Hemothorax clinical guidelines. Diagnosis and treatment of spontaneous pneumothorax. Open chest wound

The term “spontaneous pneumothorax” (SP) (as opposed to the term “traumatic pneumothorax”) was first proposed by A. Hard in 1803. SP is diagnosed in 5-7 people per 100 thousand population per year. Patients with SP make up 12% of all hospitalized patients with acute diseases of the chest organs. Non-traumatic SP can occur due to various diseases, as well as during medical manipulations (iatrogenic pneumothorax (IP)) (Tables 1, 2). Mortality in severe clinical forms of pneumothorax reaches from 1.3 to 10.4%.

The goals of treatment for SP are resolution of pneumothorax (expansion of the lung) and prevention of recurrent pneumothorax (prevention of relapse). Naturally, the tactics for achieving these goals depend on the cause of pneumothorax, its volume and the general condition of the patient. Possible methods of treating pneumothorax (due to the actual evacuation of air from the pleural cavity) include:
- puncture of the pleural cavity with air aspiration;
- drainage of the pleural cavity according to Bulau;
- drainage of the pleural cavity with active aspiration.
Additional administration of drugs for medicinal pleurodesis is aimed at preventing relapse.
Open operations and video-assisted interventions are used for suturing large defects of lung tissue, resection of bullous areas of the lung, single large bullae, etc. In this case, additional mechanical, thermal, and chemical pleurodesis is possible. The effectiveness of pleurodesis performed during surgical interventions is superior to the effectiveness of pleurodesis performed during drainage of the pleural cavity.

The incidence of complications after traditional thoracotomy for SP can reach 10.4-20%, and mortality - 2.3-4.3%, which is associated with the development of complications in the postoperative period, such as pleural empyema, postoperative pneumonia, thromboembolism of the branches of the pulmonary artery .

In recent years, in specialized hospitals for SP, predominantly video-assisted operations have been performed, and among all thoracoscopic operations, video-assisted thoracoscopy (VTS) for SP accounts for about 45%. In many centers, video-assisted thoracoscopy is the primary surgical treatment for pneumothorax. The advantages of the method compared to open thoracotomy are obvious: reduction in operation and drainage time, reduction in the number of postoperative complications, less severe pain in the postoperative period, reduction in the total number of bed days. According to a multicenter study, the rate of recurrence of pneumothorax after VAT is 4%. Other authors note an even lower rate of relapse of SP after VTS treatment - 1.3%, and there are no complications inherent in standard thoracotomy. The incidence of PU development: with transthoracic fine-needle puncture biopsy - 15-37%, on average - 10%; during catheterization of central veins - 1-10%; with thoracentesis - 5-20%; with pleural biopsy - 10%; with transbronchial lung biopsy - 1-2%; during artificial ventilation - 5-15%.

Materials and methods
From 1970 to 2013, 882 patients were treated for pneumothorax in the department of thoracic surgery of City Clinical Hospital No. 61 (in 1970-1986 - 144 people, in 1987-1995 - 174, in 1996-2013 - 564) . Until 1987, the only method of treating pneumothorax accepted in the clinic was drainage of the pleural cavity with active aspiration. For active aspiration, various devices were used: from “OP-1” to the more modern “Elema-N PRO 1” and “Medela”.

Since 1987, in addition to drainage of the pleural cavity, drug pleurodesis began to be used. To carry it out, tetracycline (20 mg per 1 kg of patient’s body weight), morphocycline 0.3 g (daily dose), and more recently doxycycline (20 mg per 1 kg of patient’s body weight) were used. Medical pleurodesis was performed both during surgical and conservative treatment of pneumothorax. During surgical treatment, 0.8 g (maximum daily dose) of a solution of doxycycline in 50 ml of 0.9% NaCl was injected into the pleural cavity. In total, from 1987 to 2013, 250 medicinal pleurodeses were performed during the conservative treatment of pneumothorax. During the period from 1987 to 1995, only 2 operations were performed - atypical lung resections using the UDO, UO, and US staplers. The approach used during the operations was lateral thoracotomy. With the introduction of video endoscopic technologies (since 1996), surgical activity in the treatment of pneumothorax was 28.5%; over the past 3 years, this figure has increased to 61.7% with the development of pneumothorax in patients with bullous pulmonary disease. From 1996 to 2013, a total of 170 operations for pneumothorax were performed.

Endostaplers are used for VTS of atypical resection of bullous areas of lung tissue. In video-assisted operations from a mini-access, the most commonly used staplers are UDO-20 and UDO-30. Thermal surgical instruments were used for coagulation of bullous-fibrotic areas of the lungs and, to a greater extent, for coagulation of subpleural vesicles and thermal pleurodesis.
The operation of choice is VTS with atypical lung resection, coagulation of bullae with thermal surgical instruments, thermal pleurodestruction of the parietal pleura with the same instruments and medicinal pleurodesis with doxycycline solution.

Results and discussion
140 VTS operations were performed: 114 VTS + atypical lung resection (81.4%), 26 VTS + coagulation of bullae and/or depleurized areas of the lung (18.5%). Coagulation of bullae and blebs with a plasma flow has become the most effective. 36 patients underwent atypical lung resection from a mini-thoracotomy approach with video assistance and the use of UDO staplers. Traditional thoracotomy was used 8 times to perform atypical lung resection.

In recent years (2003-2013), 165 patients with JP were observed in the thoracic department of City Clinical Hospital No. 61, 94 patients were transferred from Moscow hospitals and 71 from other departments of the hospital. The main causes of PU were: catheterization of the central (mainly subclavian) vein and pleural puncture for hydrothorax of various origins, less often - barotrauma during artificial ventilation of the lungs, and even less often - during transthoracic or transbronchial puncture biopsy of the lung. The main reason for transfer to the department from other hospitals was the recurrence of pneumothorax after short-term drainage of the pleural cavity: the drainage was removed on the first day (or immediately) after expansion of the lung, which required repeated (often multiple) drainage of the pleural cavity. Early removal of the drainage was explained by the fear of infection of the pleural cavity and the development of associated complications - pleural empyema.

Relapses during the treatment of SP using drainage and puncture of the pleural cavity were observed in 21.5% of cases; with drainage followed by medicinal pleurodesis - in 5.5%. There were no early relapses (after drainage without pleurodesis, recurrent pneumothorax developed in 4.9% of cases in the next 10 days after discharge). The only complication of drainage of the pleural cavity is subcutaneous emphysema. There were no complications associated with medicinal pleurodesis.

In accordance with national clinical guidelines for the diagnosis and treatment of SP, expectant management is acceptable if the volume of spontaneous limited apical pneumothorax is less than 15% in patients with no dyspnea. If such patients have bullous disease and there are no contraindications, relapse prevention will involve surgical treatment to the extent of resection of bullous areas of lung tissue. When the volume of pneumothorax is up to 30% in patients without severe dyspnea, a single pleural puncture with air aspiration can be performed. Prevention of relapse is achieved in the same way as in the previous case.
Drainage of the pleural cavity is indicated when the volume of pneumothorax is more than 30%, recurrent pneumothorax, ineffective puncture, in patients with dyspnea and patients over 50 years of age. Key points of correct placement of drainage: mandatory polypositional x-ray examination before drainage and monitoring the position of the drainage with its correction as necessary after manipulation.
However, the results of treatment of SP exclusively with punctures and drainage of the pleural cavity in patients with bullous disease cannot be considered satisfactory: recurrence of pneumothorax is observed in 20-45% of cases when treated with pleural punctures, in 12-18% after closed drainage of the pleural cavity. In this regard, at present, in the absence of contraindications to VTS, operations with marginal resection and thermal destruction of bullous areas of the lung are performed in all patients with bullous lung disease.
The operation is completed with medicinal pleurodesis with solutions of tetracycline antibiotics in order to obliterate the pleural cavity, which serves as the prevention of pneumothorax even if the bulla ruptures (Fig. 1-4).

UP, unlike SP, develops against the background of healthy lung tissue or changes in the lung parenchyma that are insufficient for spontaneous lung rupture, so UP is an indication only for conservative treatment. In this case, it is important that active aspiration continues until the lung is completely expanded, and for at least 5-7 days after expansion, until adhesions develop in the pleural cavity. When the lung is expanded, there is no danger of infection of the pleural cavity and the development of pleural empyema, since there is no actual cavity in the pleura.

Classification


Clinical classification:
- Primary (idiopathic) pneumothorax
- Secondary (symptomatic) pneumothorax
- Catamenial (menstrual) pneumothorax

Primary (idiopathic) pneumothorax persists in the ratio of 5:100 thousand people: among men 7.4:100 thousand, among women 1.2:100 thousand of the population, it occurs most often in people of working age from 20-40 years.
Secondary (symptomatic) pneumothorax is: among men 6.3:100 thousand, among women 2.0:100 thousand of the population, covers a wider age range and is often one of the manifestations of pulmonary tuberculosis.
Catamenial (Menstrual) pneumothorax is a rare form of pneumothorax that occurs in women. More than 230 cases of catamenial pneumothorax have been described worldwide.

Depending on the type of pneumothorax, there are :
- Open pneumothorax.
- Closed pneumothorax.
- Tension (valve) pneumothorax.

With an open pneumothorax, there is a connection between the pleural cavity and the lumen of the bronchus and, therefore, with atmospheric air. On inhalation, air enters the pleural cavity, and on exhalation it leaves it through a defect in the visceral pleura. In this case, the lung collapses and is switched off from breathing (lung collapse).
With a closed pneumothorax, air that has entered the pleural cavity and caused partial and complete collapse of the lung subsequently loses contact with atmospheric air and does not cause a threatening condition.
With valve pneumothorax, air freely enters the pleural cavity during inspiration, but its exit is difficult due to the presence of a valve mechanism.
According to their prevalence, they are divided into: total and partial pneumothorax.
Depending on the presence of complications: uncomplicated and complicated (bleeding, pleurisy, mediastinal emphysema).

Diagnostics


II. METHODS, APPROACHES AND PROCEDURES FOR DIAGNOSIS AND TREATMENT

List of basic and additional diagnostic measures

Basic:
1. History taking
2. Inspection, auscultation and percussion of the chest
3. General blood test
4. General urine test
5. Biochemical blood tests
6. Blood for blood type and Rh factor
7. Blood coagulogram
8. Microreaction
9. Blood test for hepatitis and HIV
10. Feces on worm eggs
11. ECG
12. Radiography in two projections

Additional:
1. Computed tomography of the chest organs in spiral mode
2. Fiberoptic bronchoscopy
3. Consultations with specialists (according to indications)

Diagnostic tactics at the outpatient (prehospital) stage:
- If sudden (spontaneous) pain appears in the chest and suspicion of SP occurs, a chest x-ray (in anterior and lateral projections) is indicated.
- If it is impossible to carry out radiography, it is necessary to send the patient to a surgical hospital.

Diagnostic tactics in a general surgical hospital.
The main goal of diagnostics in a surgical hospital is to establish an accurate diagnosis and determine therapeutic and surgical tactics.
- X-ray of the chest organs in frontal and lateral projections during exhalation (direct observation, lateral projection on the side of pneumothorax);
- CT scan of the chest in a spiral mode (additionally, according to indications);
It is recommended to use computed tomography in the differential diagnosis of pneumothorax and bullous emphysema, if improper placement of drainage is suspected, and in cases where the interpretation of a chest radiograph is difficult due to the presence of subcutaneous emphysema (level C).

Diagnostic tactics in the thoracic department.
To determine the cause of spontaneous pneumothorax, it is recommended to perform a CT examination of the thoracic segment and, based on its results, make a decision on planned surgical treatment.

Diagnostic criteria
SP in most cases occurs at a young age and is characterized by a relapsing course.
The reasons for SP may be:
1. Pulmonary emphysema, most often bullous (71-95%)
2. COPD
3. Cystic fibrosis
4. Bronchial asthma
5. Rheumatoid arthritis
6. Ankylosing spondylitis
7. Dermatomyositis
8. Systemic scleroderma
9. Marfan syndrome
10. Ehlers-Danlos syndrome
11. Idiopathic pulmonary fibrosis
12. Sarcoidosis
13. Histiocytosis X
14. Lymphangioleiomyomatosis
15. Pulmonary endometriosis

Complaints and anamnesis:
In the classic version, the joint venture begins with the appearance of:
- sudden pain in the chest,
- non-productive cough,
- shortness of breath.
In 15 - 21% of cases, pneumothorax is asymptomatic or with a blurred clinical picture without characteristic complaints of respiratory failure. .

Physical examination:
The main signs of pneumothorax during an objective examination of the patient are:
- forced position, pale skin, cold sweat and/or cyanosis
- expansion of the intercostal spaces, lag in breathing of the affected half of the chest, swelling and pulsation of the neck veins, subcutaneous emphysema is possible.
- upon percussion, weakening or absence of vocal tremor on the affected side, tympanic sound (with the accumulation of fluid in the pleural cavity in the lower parts, dullness is determined), displacement of the area of ​​the apical impulse and the boundaries of cardiac dullness to the healthy side.
- weakening of breathing upon auscultation
In the process of diagnosis and selection of treatment tactics, complicated forms of spontaneous pneumothorax require a special approach:
- tension pneumothorax
- hemothorax, ongoing intrapleural bleeding
- bilateral pneumothorax
- pneumomediastinum.

Laboratory research: not informative

Instrumental studies:
- X-ray of the chest organs in frontal and lateral projections during exhalation (direct view, lateral projection on the side of pneumothorax): a collapsed lung is determined, the presence of free air; :
- ECG (for the purpose of differential diagnosis with ischemic heart disease);
- CT scan of the chest in a spiral mode: CT picture of pneumothorax, bullous changes. :

Indications for consultation with specialists:
Specialists of a different profile - in the presence of corresponding concomitant pathology or in case of secondary and recurrent pneumothorax during planned hospitalization.
Anesthesiologist: to determine the type of anesthesia if surgical intervention is necessary, as well as to coordinate the tactics of managing the preoperative period.
Resuscitator: to determine indications for treating a patient in an intensive care unit, to coordinate the tactics of managing a patient with SP.

Differential diagnosis


Differential diagnosis:

Nosologies Characteristic syndromes or symptoms Differentiation test
IHD Acute pain behind the sternum, squeezing in nature, radiating to the left upper limb. There may be a history of angina or the presence of risk factors (smoking, hypertension, diabetes, obesity). ECG - signs of ischemia (ST segment isoline, T wave inversion, left bundle branch block)
Lower lobe pneumonia Productive cough with fever, auscultation - bronchial breathing, crepitating wheezing, dullness on percussion. X-ray - darkening in the lower parts of the lung on the affected side.

Treatment abroad

Get treatment in Korea, Israel, Germany, USA

Get advice on medical tourism

Treatment


Treatment goals: Complete expansion of the lung on the side of the pneumothorax.

Treatment tactics

Non-drug treatment
Diet: table No. 15, bed rest during hospitalization.

Drug treatment
Antibiotic therapy is not the main conservative treatment method. Its main purpose is preventive and for complicated forms of SP. The duration of therapy in the postoperative period depends on the characteristics of the clinical course. In complicated cases, it can be prolonged according to indications. The absence of symptoms of fever within 24 hours and normal white blood cell counts are criteria for stopping antibiotic therapy.

Other treatments

Surgical intervention

Treatment tactics at the outpatient (prehospital) stage
In case of tension pneumothorax, puncture or drainage is indicated on the side of the pneumothorax in the II intercostal space along the midclavicular line or along the lateral surface of the chest in the III-VII intercostal space for the purpose of decompression of the pleural cavity

Treatment tactics in a general surgical hospital
"Minor surgery" - Drainage of the pleural cavity: The pleural cavity should be drained with drainage with a diameter of at least 14 Fr -18 Fr with active aspiration with a vacuum of 20-40 cm of water. Art. or according to Bulau. (level B)
Active aspiration of the pleural cavity using vacuum aspirators (stationary and portable).

To decide on further management tactics, an examination by a thoracic surgeon is necessary.

N/B! SP with ongoing intrapleural bleeding, tension pneumothorax against the background of a drained pleural cavity is an indication for emergency or urgent surgery. After elimination of complications, pleural induction is required. Anti-relapse surgery is not recommended for patients with uncomplicated course of SP in a non-specialized surgical hospital.

Treatment tactics in the thoracic department
- when a patient is admitted to the thoracic department after an X-ray examination, if it is impossible to perform an urgent CT scan, a diagnostic thoracoscopy is performed. Depending on changes in the pleural cavity, the procedure can be completed by draining the pleural cavity or performing anti-relapse surgical treatment.
- if a patient with SP is transferred from another medical institution with an already drained pleural cavity, it is necessary to assess the adequacy of the drainage function. If the drainage is functioning adequately and diagnostic thoracoscopy has been performed in another medical institution, repeated drainage is not required, and the decision on the need for anti-relapse surgery is made based on the established cause of SP.
- if air flow through the drains continues for 72 hours, thoracoscopic surgery or video-assisted mini-thoracotomy is also indicated. The extent of surgery depends on the specific intraoperative finding.
- in case of relapse of SP, it is necessary to drain the pleural cavity, achieving expansion of the lung. Surgical treatment should be carried out in a delayed or planned manner.

N/B! Anti-relapse treatment is surgery in the chest cavity to identify and eliminate the cause of pneumothorax, as well as induce pleura in one way or another to prevent recurrence of pneumothorax.

After any method of treating spontaneous pneumothorax, conservative or surgical, relapses are possible.

N/B! If the patient refuses hospitalization, the patient and his relatives should be warned about the possible consequences. The situation must be documented by an appropriate entry in the medical record and medical history.

It is preferable to perform anti-relapse surgery in a low-traumatic manner using video-assisted thoracoscopic technology or video-assisted technology (VATS). (level C). If technical difficulties are expected during thoracoscopy, surgery from a thoracotomy or sternotomy approach is possible. .
For patients who need anti-relapse treatment, but have contraindications to surgical treatment, pleural induction and pleurodesis using chemical sclerosants introduced into the drainage or through a trocar are possible.

The purpose of surgical intervention for SP:
1. Inspection of the lung and pleural cavity with elimination of the source of air intake by:
- resection of bullae
- dressings of bullae
- suturing of broncho-pleural fistula
- coagulation bullae
- excision, suturing or stitching of other bullae that do not contain a defect
- pleurectomy
- pleurodesis
- economical resection of the lobe
Regardless of the presence or absence of bullous changes, a biopsy of the lung tissue is necessary.

N/B! The volume and method of surgical treatment is determined by the severity and nature of changes in the lung and pleural cavity, the presence of complications, the age and functional state of the patient. Surgical tactics may change intraoperatively.

Preventive actions: There is no special prevention of SP.

Further management
In the postoperative period, the pleural cavity is drained by one or more drainages, depending on the type and volume of surgery. Drains with a diameter of at least 12 Fr. In the early postoperative period, active aspiration of air from the pleural cavity with a vacuum of 20-40 cm of water is indicated. Art. (level D).
To control the expansion of the lung, a dynamic X-ray examination is performed. The amount is determined by the thoracic surgeon according to indications individually for each patient.
The criteria for the possibility of removing pleural drainage are: complete expansion of the lung according to X-ray examination, no air flow through the drainage for 24 hours, and discharge through the pleural drainage of less than 150 ml/day.
Before removal of chest tubes, patients are advised to receive prophylactic antibiotic therapy.
Discharge in an uncomplicated postoperative period is possible after removal of the pleural drainage, with mandatory X-ray monitoring before discharge.

Indicators of treatment effectiveness and safety of diagnostic and treatment methods described in the protocol:
- complete expansion of the lung, determined radiographically;
- cessation of air flow through the pleural drainage for 24 hours.
Despite the mandatory implementation of all points of the protocol, there must be a personalized and individual approach to each patient based on the actual clinical situation.

Groups of drugs according to ATC used in treatment

Hospitalization


Indications for hospitalization

general information

Short description

Definition:

Spontaneous pneumothorax (SP) is a syndrome characterized by the accumulation of air in the pleural cavity, not associated with lung injury or medical manipulation.

ICD 10 code: J93.1

Prevention:
Induction of pleurodesis, that is, the formation of adhesions in the pleural cavity, reduces the risk of recurrent pneumothorax [A].
Quitting smoking reduces both the risk of developing pneumothorax and the risk of its recurrence [ C].

Screening:
Screening is not applicable for primary pneumothorax.
For secondary - it is aimed at identifying diseases that provoke the development of spontaneous pneumothorax.

Classification


Classifications

Table 1. Classification of spontaneous pneumothorax

By etiology:
1. Primary is a pneumothorax that occurs without obvious causes in previously healthy individuals. Caused by primary bullous pulmonary emphysema
Caused by primary diffuse pulmonary emphysema

Table 2. The most common causes of secondary pneumothorax

Note: The accumulation of air in the pleural cavity resulting from rupture of cavities of destruction of lung tissue (in tuberculosis, abscess pneumonia and cavitary lung cancer) should not be classified as secondary pneumothorax, since in these cases acute pleural empyema develops.

Diagnostics


Diagnostics:

Diagnosis of SP is based on the clinical manifestations of the disease, objective and radiological examination data.

In the clinical picture, the main place is occupied by: pain in the chest on the side of the pneumothorax, often radiating to the shoulder, shortness of breath, dry cough.

Rare complaints - usually appear in complicated forms of SP. Changes in voice timbre, difficulty swallowing, an increase in the size of the neck and chest occur with pneumomediastinum and subcutaneous emphysema. With hemopneumothorax, the manifestations of acute blood loss come to the fore: weakness, dizziness, orthostatic collapse. Palpitations and a feeling of interruptions in the heart (arrhythmia) are characteristic of tension pneumothorax. Late complications of pneumothorax (pleurisy, empyema) lead to the patient developing symptoms of intoxication and fever.

With secondary SP, even if it is small in volume, there are more pronounced clinical symptoms, in contrast to primary SP [D].

An objective examination reveals a lag in breathing of half the chest, sometimes widening of the intercostal spaces, a tympanic tone during percussion, weakening of breathing and weakening of vocal tremor on the side of the pneumothorax.

With tension pneumothorax, clinical manifestations are more pronounced [D].

It is mandatory to take radiographs in frontal and lateral projections during inspiration, which are sufficient to make a diagnosis of pneumothorax [A]. In doubtful cases, it is necessary to take an additional expiratory photograph in a direct projection.

The main radiological symptoms of SP are:

  • absence of a pulmonary pattern in the peripheral parts of the corresponding hemithorax;
  • visualization of the outlined edge of the collapsed lung;
With severe lung collapse, additional radiological symptoms may be detected:
  • shadow of a collapsed lung;
  • symptom of deep furrows (in lying patients);
  • mediastinal shift;
  • changing the position of the diaphragm.

When assessing radiographs, it is necessary to remember the possibility of limited pneumothorax, which, as a rule, has an apical, paramediastinal or supradiaphragmatic localization. In these cases, it is necessary to perform inspiratory and expiratory radiographs, the comparison of which provides complete information about the presence of limited pneumothorax.
An important task of x-ray examination is to assess the condition of the lung parenchyma, both the affected and the opposite lung.

When assessing radiographs, pneumothorax should be differentiated from giant bullae, destructive processes in the lungs, and dislocation of hollow organs from the abdominal cavity to the pleural cavity.

Before draining the pleural cavity, it is necessary to perform radiography in 2 projections or polypositional fluoroscopy to determine the optimal drainage point [D].

Spiral computed tomography (SCT) of the chest plays a major role in determining the causes of pneumothorax and differential diagnosis of SP with other pathologies. SCT should be performed after drainage of the pleural cavity and the maximum possible expansion of the lung. With SCT, the following signs are assessed: the presence or absence of changes in the pulmonary parenchyma, such as infiltration, disseminated process, interstitial changes; unilateral or bilateral bullous changes; diffuse emphysema.
Indicators of laboratory tests in cases of uncomplicated spontaneous pneumothorax, as a rule, are not changed.

Treatment


Treatment:
All patients with pneumothorax should be urgently hospitalized in thoracic surgical hospitals, and if impossible, in emergency surgical hospitals.

Treatment goals for spontaneous pneumothorax:

  • expansion of the lung;
  • cessation of air flow into the pleural cavity;
  • prevention of disease relapse;

The fundamental points for determining surgical tactics for pneumothorax are: the presence of respiratory and, even to a greater extent, hemodynamic disorders, the frequency of formation, the degree of lung collapse and the etiology of pneumothorax. In all cases, it is necessary to clarify the nature of changes in the pulmonary parenchyma before surgery using all possible methods, preferably SCT.
Emergency surgical care for spontaneous pneumothorax should be aimed, first of all, at decompressing the pleural cavity and preventing respiratory and circulatory disorders, and only then at performing radical surgery.
Tension pneumothorax occurs in cases where a defect in the lung functions as a valve, while an increase in intrapleural pressure leads to a total collapse of the lung, a progressive decrease in alveolar ventilation on the affected side, and then on the healthy side, pronounced shunting of the blood flow, as well as a shift of the mediastinum to the healthy side side, leading to a decrease in stroke volume of blood circulation up to extrapericardial cardiac tamponade.

Treatment methods for spontaneous pneumothorax:

  • conservative - dynamic observation;
  • pleural puncture;
  • drainage of the pleural cavity;
  • chemical pleurodesis through pleural drainage;
  • surgical intervention.

1. Dynamic observation
Conservative treatment involves clinical and radiological monitoring, in combination with a protective regimen, pain relief, oxygen therapy and, if indicated, preventive antibacterial therapy.
Observation, as the method of choice, is recommended for small, non-strained primary SP occurring without respiratory failure [ B].
For small apical or limited pneumothorax, the risk of pleural puncture exceeds its therapeutic value [ D]. Air from the pleural cavity is resorbed at a rate of about 1.25% of the volume of the hemithorax in 24 hours, and oxygen inhalation increases the rate of air resorption from the pleural cavity by 4 times.

2. Pleural puncture
Indicated for patients under 50 years of age with the first episode of spontaneous pneumothorax with a volume of 15 - 30% without severe dyspnea. The puncture is performed using a needle or, preferably, a thin stylet catheter. A typical place for puncture is the 2nd intercostal space along the midclavicular line or the 3rd - 4th intercostal space along the midaxillary line, however, the puncture point should be determined only after a polypositional x-ray examination, which makes it possible to clarify the localization of adhesions and the largest accumulations of air. It is important to remember that if the first puncture is ineffective, repeated attempts at aspiration are successful in no more than one third of cases [B].
If the lung does not expand after pleural puncture, drainage of the pleural cavity is recommended. [A].

3. Drainage of the pleural cavity
Drainage of the pleural cavity is indicated when pleural puncture is ineffective; with large SP, with secondary SP, in patients with respiratory failure, and in patients over 50 years of age [B].
Drainage should be installed at a point selected based on the results of the x-ray examination. In the absence of adhesions, drainage is performed in the 3rd - 4th intercostal space along the mid-axillary line or in the 2nd intercostal space along the midclavicular line.
The most common methods of drainage of the pleural cavity for pneumothorax are stylet and trocar. You can also install drainage through a guidewire (Seldinger technique) or using a clamp. The procedure for draining the pleural cavity is performed under aseptic conditions in a dressing room or operating room.
The drainage is inserted to a depth of 2 - 3 cm from the last hole (inserting the tube too deeply will not allow it to function adequately, and the location of the holes in the soft tissues can lead to the development of tissue emphysema) and is securely fixed with skin sutures. Immediately after drainage, the drainage is lowered to the bottom of a jar with an antiseptic solution (Bulau drainage) and subsequently connected to a pleuroaspirator. The pleural cavity is carried out using active aspiration with individual selection of vacuum until air discharge stops. It should be taken into account that with prolonged lung collapse before hospitalization, the risk of developing reperfusion pulmonary edema after its expansion increases. [D].

Diagnostic thoracoscopy (DT), performed during drainage.
If it is impossible to perform SCT urgently, to identify the cause of pneumothorax and determine further tactics, it is advisable to perform diagnostic thoracoscopy during drainage. It should be taken into account that DT does not provide a complete opportunity to identify intrapulmonary changes.
The operation is performed under local anesthesia on the side of the pneumothorax, with the patient lying on the healthy side. The location for installing the thoracoport is selected based on the results of an X-ray examination. In patients with complete lung collapse, a thoracoport is installed in the 4th or 5th intercostal space along the mid-axillary line.
The pleural cavity is sequentially inspected (the presence of exudate, blood, adhesions), the lung is examined (blebs, bullae, fibrosis, infiltrative, focal changes), and in women the diaphragm is specifically assessed (scars, through defects, pigment spots). Macroscopic changes in the pulmonary parenchyma and pleural cavity identified during DT should be assessed according to the classification of Vanderschuren R. (1981) and Boutin C. (1991).

Classification of morphological types detected in the pleural cavity and pulmonary parenchyma in patients with spontaneous pneumothorax
(Vanderschuren R. 1981, Boutin C. 1991).
Type I - absence of visual pathology.
Type II - the presence of pleural adhesions in the absence of changes in the lung parenchyma.
Type III - small subpleural bullae less than 2 cm in diameter.
Type IV - large bullae, more than 2 cm in diameter.

The operation is completed by draining the pleural cavity. The pleural cavity is maintained under active aspiration until air discharge stops. Active aspiration with a vacuum of 10-20 cm of water column is considered optimal. [ B]. However, the most beneficial is aspiration with the minimum vacuum at which the lung fully expands. The method for choosing the optimal vacuum is as follows: under fluoroscopy control, we reduce the vacuum to the level when the lung begins to collapse, after which we increase the vacuum by 3 - 5 cm of water. Art. When complete expansion of the lung is achieved, there is no passage of air for 24 hours and fluid intake is less than 100-150 ml, the drainage is removed. There is no exact timing for drainage removal; aspiration should be carried out until the lung is completely expanded. X-ray monitoring of lung expansion is performed daily. If air flow from the pleural cavity ceases within 12 hours, the drainage is closed for 24 hours and then an x-ray is taken. If the lung remains expanded, the drainage is removed. The next day after removal of the drainage, it is necessary to perform a control x-ray of the chest to confirm the elimination of pneumothorax.
If, despite drainage, the lung does not expand and the flow of air through the drainage continues for more than 3 days, urgent surgical treatment is indicated.

4. Chemical pleurodesis
Chemical pleurodesis is a procedure in which substances are introduced into the pleural cavity, leading to aseptic inflammation and the formation of adhesions between the visceral and parietal layers of the pleura, which leads to obliteration of the pleural cavity.
Chemical pleurodesis is used when it is impossible for some reason to perform radical surgery. [B].
The most powerful sclerosing agent is talc; its introduction into the pleural cavity is rarely accompanied by the development of respiratory distress syndrome and pleural empyema [ A] . Studies of 35 years of results from the use of asbestos-free chemically pure talc have proven that it is not carcinogenic [ A]. The talc pleurodesis technique is quite labor-intensive and requires spraying 3-5 grams of talc using a special sprayer introduced through a trocar before draining the pleural cavity.
It is important to remember that talc does not cause an adhesive process, but granulomatous inflammation, as a result of which the parenchyma of the mantle zone of the lung fuses with the deep layers of the chest wall, which causes extreme difficulties for subsequent surgical intervention. Therefore, indications for talc pleurodesis should be strictly limited to only those cases (senile age, severe concomitant diseases) when the likelihood that subsequent surgery in the obliterated pleural cavity will be required is minimal.
The next most effective drugs for pleurodesis are antibiotics of the tetracycline group (doxycycline) and bleomycin. Doxycycline should be administered at a dose of 20 - 40 mg/kg, if necessary, the procedure can be repeated the next day. Bleomycin is administered at a dose of 100 mg on the first day and, if necessary, pleurodesis of bleomycin 200 mg is repeated on subsequent days. Due to the severity of pain during pleurodesis with tetracycline and bleomycin, it is necessary to dilute these drugs in 2% lidocaine and be sure to premedicate with narcotic analgesics [WITH]. After drainage, the drug is administered through a drain, which is clamped for 1 - 2 hours, or, with constant air release, passive aspiration is carried out according to Bulau. During this time, the patient must constantly change body position to evenly distribute the solution over the entire surface of the pleura.
When the lung is not expanded, chemical pleurodesis through pleural drainage is ineffective, since the layers of the pleura do not touch and adhesions do not form. In addition, in this situation, the risk of developing pleural empyema increases.
Despite the fact that other substances are used in clinical practice: sodium bicarbonate solution, povidone iodine, ethyl alcohol, 40% glucose solution, etc., it should be remembered that there is no evidence of the effectiveness of these drugs.

5. Use of endobronchial valves and obturators
If air discharge continues and it is impossible to expand the lung, one of the methods is bronchoscopy with the installation of an endobronchial valve or obturator. The valve is installed for 10-14 days using both a rigid bronchoscope under anesthesia and a fiberoptic bronchoscope under local anesthesia.
In most cases, a valve or obturator allows the defect to be sealed and leads to expansion of the lung.

6. Surgical treatment

Indications and contraindications
Indications for emergency and urgent surgery:
1. hemopneumothorax;
2. tension pneumothorax with ineffective drainage.
3. continued release of air when it is impossible to expand the lung
4. continued air release for more than 72 hours with the lung expanded

Indications for planned surgical treatment:
1. recurrent, including contralateral pneumothorax;
2. bilateral pneumothorax;
3. the first episode of pneumothorax when bullae or adhesions are detected (II-IV type of changes according to Vanderschuren R. and Boutin C.);
4. endometriosis-dependent pneumothorax;
5. suspicion of secondary pneumothorax. The operation is of a therapeutic and diagnostic nature;
6. professional and social indications - patients whose work or hobbies are associated with changes in pressure in the respiratory tract (pilots, parachutists, divers and musicians playing wind instruments).
7. rigid pneumothorax

Basic principles of surgical treatment of spontaneous pneumothorax
Surgical tactics for spontaneous pneumothorax are as follows. After a physical and polypositional X-ray examination, which allows one to assess the degree of lung collapse, the presence of adhesions, fluid, and mediastinal displacement, it is necessary to perform a puncture or drainage of the pleural cavity.
At the first episode of pneumothorax an attempt at conservative treatment is possible - puncture or drainage of the pleural cavity. If the treatment is effective, SCT should be performed, and if bullae, emphysema and interstitial lung diseases are detected, elective surgery should be recommended. If there are no changes in the lung parenchyma that are subject to surgical treatment, then we can limit ourselves to conservative treatment, recommending that the patient adhere to a regimen of physical activity and SCT monitoring once a year. If drainage does not lead to expansion of the lung and air flow through the drains continues for 72 hours, urgent surgery is indicated.

If pneumothorax recurs surgery is indicated, however, it is always preferable to first perform drainage of the pleural cavity, achieve expansion of the lung, then perform a CT scan, assess the condition of the lung tissue, paying special attention to signs of diffuse emphysema, COPD, interstitial diseases and processes of destruction of lung tissue; and perform the operation as planned. The preferred approach is thoracoscopic. The exceptions remain rare cases of complicated pneumothorax (continuing massive intrapleural bleeding, fixed lung collapse), intolerance to one-lung ventilation.
Surgical techniques for the surgical treatment of pneumothorax can be divided into three stages:
audit,
surgery on a modified area of ​​the lung,
obliteration of the pleural cavity.

Revision technique for spontaneous pneumothorax
Thoracoscopic examination allows not only to visualize changes in lung tissue characteristic of a particular disease, but also, if necessary, to obtain biopsy material for morphological verification of the diagnosis. To assess the severity of emphysematous changes in the parenchyma, it is most advisable to use the R. Vanderschuren classification. A thorough assessment of the severity of emphysematous changes makes it possible to predict the risk of recurrent pneumothorax and make an informed decision about the type of operation aimed at obliterating the pleural cavity.
The success of the operation depends to the greatest extent on whether the source of air supply was found and eliminated. The frequently held opinion that with thoracotomy it is easier to detect the source of air intake is only partly true. According to a number of studies, the source of air intake cannot be detected in 6 - 8% of cases of spontaneous pneumothorax.
As a rule, these cases are associated with the entry of air through the micropores of an unruptured bulla or occur when a thin pleural adhesion is torn off.
To detect the source of air intake, the following technique is advisable. Pour 250 - 300 ml of sterile solution into the pleural cavity. The surgeon presses all suspicious areas one by one with an endoscopic retractor, immersing them in liquid. The anesthesiologist connects the open bronchial canal of the endotracheal tube to the Ambu bag and, at the surgeon’s command, takes a small breath. As a rule, with a thorough sequential inspection of the lung, it is possible to detect the source of air intake. As soon as you can see a chain of bubbles rising from the surface of the lung, you should, carefully manipulating the retractor, turn the lung so that the source of air intake is as close as possible to the surface of the sterile solution. Without removing the lung from under the liquid, it is necessary to grasp its defect with an atraumatic clamp and make sure that the air supply has stopped. After this, the pleural cavity is drained and suturing of the defect or lung resection begins. If, despite a thorough inspection, the source of air intake could not be detected, it is necessary not only to eliminate the existing intact bullae and blebs, but also, without fail, to create conditions for obliteration of the pleural cavity - to perform pleurodesis or endoscopic parietal pleurectomy.

Pulmonary stage of the operation
The operation of choice is resection of the altered area of ​​the lung (marginal, wedge-shaped), which is performed using endoscopic staplers that ensure the formation of a reliable hermetically sealed mechanical suture.
In some cases, the following interventions may be performed:
1. Electrocoagulation of blebs
2. Opening and suturing of bullae
3. Plication of bullae without opening
4. Anatomical lung resection

For blebs, electrocoagulation can be performed, the lung defect can be sutured, or the lung can be resected within healthy tissue. Electrocoagulation of the bleb is the simplest and, with careful adherence to the technique, reliable operation. Before coagulating the surface of the bleb, it is necessary to carefully coagulate its base. After coagulation of the underlying lung tissue, the coagulation of the bleb itself begins, and one should strive to ensure that the wall of the bleb is “welded” to the underlying lung tissue, using a non-contact coagulation mode for this. Ligation using a Raeder loop, advocated by many authors, should be considered risky, since the ligature may slip off during lung reexpansion. Suturing with the EndoStitch device or manual endoscopic suture is much more reliable. The suture must be placed 0.5 cm below the base of the bleb and the lung tissue must be tied on both sides, after which the bleb can be coagulated or cut off.
For bullae, endoscopic suturing of the underlying parenchyma or lung resection using an endostapler should be performed. Coagulation of bullae cannot be used. If a single bulla ruptures no more than 3 cm in size, the lung tissue supporting the bulla can be sutured using a hand suture or the EndoStitch device. In the presence of multiple bullae or blebs localized in one lobe of the lung, if single giant bullae are ruptured, an atypical resection of the lung should be performed within healthy tissue using an endoscopic stapler. More often with bullae it is necessary to perform marginal resection, less often - wedge-shaped. When wedge-shaped resection of the 1st and 2nd segments, it is necessary to mobilize the interlobar groove as much as possible and perform the resection by sequentially applying a stapler from the root to the periphery of the lung along the border of healthy tissues.
Indications for endoscopic lobectomy in patients with SP are extremely limited; it should be performed for cystic hypoplasia of the lung lobe. This operation is much more technically difficult and can only be recommended to surgeons with extensive experience in thoracoscopic surgery. To make endoscopic lobectomy easier, you can open the cysts using endoscopic scissors with coagulation before proceeding to the treatment of the root lobe elements. After opening the cysts, the lobe collapses, providing optimal conditions for manipulation at the root of the lung. Endoscopic isolation of the lobar artery and vein, as in traditional surgery, must be performed in accordance with the “golden rule of Overhold”, first treating the visible anterior, then the lateral and only then the posterior wall of the vessel. It is easier to suture selected lobar vessels using the EndoGIA II Universal or Echelon Flex device with a white cassette. In this case, it is technically easier to bring it under the vessel “upside down”, i.e. not a cassette, but a thinner mating part of the device downwards. The bronchus should be sutured and crossed using a stapler with a blue or green cassette. Removing a lobe of the lung from the pleural cavity with cystic hypoplasia, as a rule, does not cause difficulties and can be performed through an extended trocar injection.
Endoscopic anatomical resection of the lung is technically complex and requires a large number of expensive consumables. Video-assisted lobectomy from a mini-access does not have these disadvantages, and the course of the postoperative period does not differ from that of endoscopic lobectomy.
The technique for performing video-assisted lobectomy was developed in detail and introduced into clinical practice by T.J. Kirby. The technique is as follows. The optical system is inserted into the 7-8 intercostal space along the anterior axillary line and a thorough visual inspection of the lung is performed. The next thoracoport is installed in the 8-9 intercostal space along the posterior axillary line. The lobe is isolated from the adhesions and the pulmonary ligament is destroyed. Then the intercostal space is determined, the most convenient for manipulations on the root of the lobe, and a mini-thoracotomy 4-5 cm long is performed along it, through which standard surgical instruments are passed - scissors, a pulmonary clamp and dissectors. The intersection of vessels is carried out using the UDO-38 apparatus, with mandatory additional ligation of the central stump of the vessel. The bronchus is carefully isolated from the surrounding tissue and lymph nodes, then sutured with a UDO-38 device and transected.
Pneumothorax caused by diffuse pulmonary emphysema presents particular technical difficulties. Attempts to simply suturing a rupture of emphysematous pulmonary tissue are, as a rule, futile, since each suture becomes a new and very strong source of air entry. In this regard, preference should be given to modern stitching machines that use cassettes with gaskets - or sutures using gaskets.
Both synthetic materials, for example, Gore-Tex, and free flaps of biological tissue, for example, a pleural flap, can be used as a gasket. Good results are obtained by strengthening the seam with an application of Tahocomb plate or BioGlue glue.

Obliteration of the pleural cavity
In the British Society of Thoracic Surgeons Guidelines, 2010. [ A] The results of studies of the 1st and 2nd level of evidence are summarized, on the basis of which it was concluded that pulmonary resection in combination with pleurectomy is a technique that provides the lowest percentage of relapses (~ 1%). Thoracoscopic resection and pleurectomy are comparable in recurrence rate to open surgery, but are more preferable in terms of pain, duration of rehabilitation and hospitalization, and restoration of external respiratory function.

Methods of obliteration of the pleural cavity
Chemical pleurodesis during thoracoscopy is performed by applying a sclerosing agent - talc, tetracycline solution or bleomycin - to the parietal pleura. The advantages of pleurodesis under the control of a thoracoscope are the ability to treat the entire surface of the pleura with a sclerosing agent and the painlessness of the procedure.
You can perform mechanical pleurodesis using special thoracoscopic instruments for abrading the pleura or, in a simpler and more effective version, pieces of sterilized metal sponge used in everyday life for washing dishes. Mechanical pleurodesis, performed by wiping the pleura with tuffers, is ineffective due to their rapid wetting, and cannot be recommended for use.
Physical methods of pleurodesis also give good results; they are simple and very reliable. Among them, it should be noted the treatment of the parietal pleura with electrocoagulation - in this case, it is more advisable to use coagulation through a gauze ball moistened with saline solution; This method of pleurodesis is characterized by a larger area of ​​influence on the pleura with a smaller depth of current penetration. The most convenient and effective methods of physical pleurodesis are the destruction of the parietal pleura using an argon plasma coagulator or an ultrasonic generator.
A radical operation for obliteration of the pleural cavity is endoscopic pleurectomy. This operation should be performed according to the following procedure. Using a long needle, saline solution is injected subpleurally into the intercostal spaces from the apex of the lung to the level of the posterior sinus. Along the spine at the level of the costovertebral joints, the parietal pleura is dissected along its entire length using an electrosurgical hook. Then the pleura is dissected along the lowest intercostal space at the level of the posterior phrenic sinus. The corner of the pleural flap is grasped with a clamp, and the pleural flap is peeled off from the chest wall. The pleura detached in this way is cut off with scissors and removed through a thoracoport. Hemostasis is carried out using a ball electrode. Preliminary hydraulic preparation of the pleura makes the operation easier and safer.

Features of surgical tactics for pneumothorax in patients with extragenital endometriosis
In women with SP, the cause of the disease may be extragenital endometriosis, which includes endometrial implants on the diaphragm, parietal and visceral pleura, as well as in the lung tissue. During surgery, if damage to the diaphragm is detected (fenestration and/or implantation of the endometrium), it is recommended to use resection of its tendon part or suturing of defects, plication of the diaphragm or plastic surgery with a synthetic polypropylene mesh, supplemented by costal pleurectomy. Most authors [ B] consider it necessary to carry out hormonal therapy (danazol or gonadotropin-releasing hormone), the purpose of which is to suppress menstrual function and prevent recurrence of pneumothorax after surgery.

Postoperative treatment in uncomplicated cases
1. The pleural cavity is drained with two drains with a diameter of 6-8 mm. In the early postoperative period, active aspiration of air from the pleural cavity with a vacuum of 20-40 cm of water is indicated. Art.
2. To control the expansion of the lung, a dynamic X-ray examination is performed.
3. The criteria for the possibility of removing pleural drainage are: complete expansion of the lung according to X-ray examination, absence of air and exudate through the drainage within 24 hours.
4. Discharge in an uncomplicated postoperative period is possible one day after removal of the pleural drainage, with mandatory X-ray monitoring before discharge.

Tactics of examination and treatment of patients with SP depending on the category of medical institution.

1. Organization of diagnostic and treatment care at the prehospital stage:
1. Any pain in the chest requires the targeted exclusion of spontaneous pneumothorax using radiography of the chest organs in two projections; if this study is impossible, the patient must be immediately referred to a surgical hospital.
2. In cases of tension pneumothorax, decompression of the pleural cavity is indicated by puncture or drainage on the side of the pneumothorax in the 2nd intercostal space along the midclavicular line.

2. Diagnostic and therapeutic tactics in a non-specialized surgical hospital.
The task of the diagnostic stage in a surgical hospital is to clarify the diagnosis and determine further treatment tactics. Particular attention should be paid to identifying patients with complicated forms of spontaneous pneumothorax.

1. Laboratory research:
General blood and urine analysis, blood group and Rh factor.
2. Hardware research:
- it is mandatory to perform a chest x-ray in two projections (frontal and lateral projection from the side of the suspected pneumothorax);
- ECG.
3. An established diagnosis of spontaneous pneumothorax is an indication for drainage.
4. Active aspiration of air from the pleural cavity with a vacuum of 20-40 cm of water is advisable. Art.
5. Complicated spontaneous pneumothorax (with signs of ongoing intrapleural bleeding, tension pneumothorax against the background of a drained pleural cavity) is an indication for emergency surgery through a thoracotomy approach. After the elimination of complications, obliteration of the pleural cavity is mandatory.

7. The inability to perform SCT or diagnostic thoracoscopy, recurrent pneumothorax, detection of secondary changes in the lung tissue, continued release of air and/or non-expansion of the lung for 3-4 days, as well as the presence of late complications (pleural empyema, persistent lung collapse) are indications for consultation thoracic surgeon, referral or transfer of the patient to a specialized hospital.
8. Performing anti-relapse surgical intervention in patients with uncomplicated spontaneous pneumothorax in a non-specialized surgical hospital is not recommended.

3. Diagnostic and therapeutic tactics in a specialized (thoracic) hospital.

1. Laboratory research.
- general blood and urine analysis, biochemical blood test (total protein, blood sugar, prothrombin), blood group and Rh factor.
2. Hardware research:
- SCT is mandatory, if not possible, chest x-ray in two projections (frontal and lateral projection from the side of the suspected pneumothorax) or polypositional fluoroscopy;
- ECG.
3. If a patient with spontaneous pneumothorax was transferred from another hospital with an already drained pleural cavity, it is necessary to assess the adequacy of the drainage function. If the pleural drainage is not functioning adequately, it is advisable to perform diagnostic thoracoscopy and re-drainage of the pleural cavity. If the drainage is functioning adequately, re-drainage is not required, and the decision on the need for anti-relapse surgery is made on the basis of examination data.
4. The pleural cavity is drained, and active aspiration of air from the pleural cavity with a vacuum of 20-40 cm of water is advisable. Art.
5. Complicated spontaneous pneumothorax (with signs of ongoing intrapleural bleeding, tension pneumothorax against the background of a drained pleural cavity) is an indication for emergency surgery. After elimination of complications, induction of pleurodesis is required.
6. The criteria for removal of pleural drainage are: complete expansion of the lung according to X-ray examination, no air flow through the drainage within 24 hours and no discharge through the pleural drainage.

Mistakes and difficulties in treating SP:

Errors and difficulties of drainage:
1. The drainage tube is inserted deep into the pleural cavity and is bent, which is why it cannot evacuate accumulated air and straighten the lung.
2. Unreliable fixation of the drainage, with it partially or completely coming out of the pleural cavity.
3. Against the background of active aspiration, massive air discharge persists and respiratory failure increases. Surgery is indicated.

Management of the long-term postoperative period:
After discharge from the hospital, the patient should avoid physical activity for 4 weeks.
During the 1st month, the patient should be advised to avoid changes in barometric pressure (parachute jumping, diving, air travel).
The patient should be advised to quit smoking.
Observation by a pulmonologist and examination of external respiration function after 3 months are indicated.

Forecast:
Mortality from pneumothorax is low, and is more often observed with secondary pneumothorax. In HIV-infected patients, in-hospital mortality due to the development of pneumothorax is 25%. Mortality in patients with cystic fibrosis with unilateral pneumothorax is 4%, with bilateral pneumothorax - 25%. In patients with COPD, when pneumothorax develops, the risk of death increases 3.5 times and is 5%.

Conclusion:
Thus, surgical treatment of spontaneous pneumothorax is a complex and multifaceted problem. Often, experienced surgeons call spontaneous pneumothorax “thoracic appendicitis,” implying that this is the simplest operation performed for lung diseases. This definition is doubly true - just as appendectomy can be both the simplest and one of the most complex operations in abdominal surgery, also a banal pneumothorax can create difficult problems to overcome during a seemingly simple operation.
The described surgical tactics, based on an analysis of the results of a number of leading thoracic surgery clinics and extensive collective experience in performing operations, both in very simple and in very complex cases of pneumothorax, make it possible to make thoracoscopic surgery simple and reliable, and to significantly reduce the number of complications and relapses.

ECG changes are usually detected only with tension pneumothorax: deviation of the electrical axis of the heart to the right or left depending on the location of the pneumothorax, decreased voltage, flattening and inversion of T waves in leads V1–V3.

X-ray of the chest organs

To confirm the diagnosis, it is necessary to conduct a chest x-ray (the optimal projection is anteroposterior, with the patient in an upright position).

Radiographic sign of pneumothorax - visualization of a thin line of visceral pleura (less than 1 mm), separated from the chest (Fig. 1).

Pneumothorax

Res. 1. Secondary spontaneous pneumothorax on the right in a patient with Pneumocystis pneumonia.

A common finding in pneumothorax is displacement of the mediastinal shadow to the opposite side. Since the mediastinum is not a fixed structure, even a small pneumothorax can lead to displacement of the heart, trachea and other elements of the mediastinum, so contralateral shift of the mediastinum is neither a sign of severe pneumothorax nor a sign of tension pneumothorax.

■ About 10–20% of pneumothoraxes are accompanied by the appearance of a small pleural effusion (within the sinus), and in the absence of expansion of the pneumothorax, the amount of fluid may increase.

In the absence of signs of pneumothorax according to the radiograph in the anteroposterior projection, but in the presence of clinical data in favor of pneumothorax, radiographs in the lateral position or lateral position on the side are indicated ( decubitus lateralis), which allows confirming the diagnosis in an additional 14% of cases.

Some guidelines recommend that in difficult cases, radiography be performed not only at the height of inspiration, but also at the end of expiration. However, as recent studies have shown, expiratory films have no advantages over conventional inspiratory films. Moreover, vigorous exhalation can significantly aggravate the condition of a patient with pneumothorax and even lead to asphyxia, especially with tension and bilateral pneumothorax. That's whyX-ray at expiratory height is not recommended for the diagnosis of pneumothorax.

Radiological sign of pneumothorax in a patient in a horizontal position (more often during mechanical ventilation) - a sign of a deep sulcus (deep sulcus sigh) - deepeningcostophrenicangle, which is especially noticeable when compared with the opposite side (Fig. 2).

For diagnosing small pneumothoraxes, CT is a more reliable method compared to radiography. The sensitivity of CT in detecting pneumothorax after transthoracic lung biopsy is 1.6 times higher.

For the differential diagnosis of large emphysematous bullae and pneumothorax, the most sensitive method is CT WITH .

CT is indicated to determine the cause of secondary spontaneous pneumothorax (bullous emphysema, cysts, ILD, etc.) D.

Determining the size of pneumothorax

The size of pneumothorax is one of the most important parameters determining the choice of treatment tactics. The widest application

knowledge was obtained by the Light formula, based on the position that the volume of the lung and the volume of the hemithorax are proportional to the size of their diameters raised to the third power. The size of pneumothorax using the Light formula is calculated as follows:

Volume of pneumothorax (%) = (1 - DL 3 / DH 3 ) × 100,

where DL is the diameter of the lung, DH is the diameter of the hemithorax on a chest x-ray (Fig. 3).

In patients with PSP, the correlation between the calculated data and the volume of air obtained by simple aspiration is r = 0.84 (p< 0,0001), т.е. метод может быть рекомендован для широкого использования в клинической практике.

Recurrent pneumothorax

■ Relapses, e.g. development of repeated pneumothorax after re-

recurrent primary pneumothorax, are one of the important

nary aspects of patient management. Relapses, as a rule, are not

52%, averaging 30%. The majority of relapses occur in the first 0.5–2 years after the 1st episode of pneumothorax.

■ After recurrent pneumothorax, the likelihood of subsequent recurrences increases progressively: 62% after the 2nd episode and 83% after the 3rd pneumothorax.

■ In one of the largest studies, which included 229 patients with VSP, the relapse rate was 43%.

■ The main risk factors for the development of relapses in patients with spontaneous pneumothorax (both with PSP and SSP) are the presence of pulmonary fibrosis, age over 60 years, high stature and low nutritional status of patients. The presence of subpleural bullae is not a risk factor for relapse.

Differential diagnosis

■ Pneumonia ■ Pulmonary embolism

■ Viral pleurisy ■ Acute pericarditis

■ Acute coronary syndrome ■ Rib fracture

■ Treatment goals: resolution of pneumothorax and prevention of repeated pneumothoraxes (relapses).

Indications for hospitalization. Hospitalization is indicated for all patients with pneumothorax.

■ Treatment tactics. Currently, there are two known consensus documents on the diagnosis and treatment of patients with spontaneous pneumothorax - the British Thoracic Society manual (2003) and the American College of Chest Physicians manual (2001). Despite some differences in approaches to patient management tactics, these guidelines suggest similar stages of patient treatment: observation and oxygen therapy simple aspiration installation of a drainage tube chemical spitting

A 15% pneumothorax will require approximately 8–12 days to resolve.

All patients, even with a normal arterial blood gas composition, are prescribed oxygen (10 l/min through a mask, but a positive effect is also observed when oxygen is administered through cannulas), since oxygen therapy can accelerate the resolution of pneumothorax in 4–6 timesC. The administration of oxygen is absolutely indicated for patients with hypoxemia, which can occur with tension pneumothorax even in patients without underlying lung pathology. In patients with COPD and other chronic lung diseases, blood gas monitoring is necessary when prescribing oxygen, as hypercapnia may increase.

For severe pain syndrome, it is prescribed analgesics, including narcotics; If pain is not controlled with narcotic analgesics, an epidural or intercostal blockade may be performed D.

Simple aspiration

■ Simple aspiration (pleural puncture with aspi-

walkie-talkies) are indicated for patients with PSP with a volume of more than 15%; pain-

Drainage of the pleural cavity

Early use of suction after chest tube placement (especially in patients with PSP that occurred several days ago) may lead to the development of reexpansion ( ex vacuo) pulmonary edema. Clinically, reexpansion pulmonary edema is manifested by coughing and increased shortness of breath or the appearance of chest congestion after insertion of a drainage tube. On a chest x-ray, signs of edema may be visible not only in the affected lung, but also on the opposite side. The prevalence of reexpansion pulmonary edema when using suction can reach 14%, and its risk is significantly higher with the development of pneumothorax for more than 3 days, complete collapse of the lungs, and young patients (less than 30 years).

When air bubbles are released, clamping (squeezing) the drainage tube is unacceptable, since such an action can lead to the development of tension pneumothorax WITH . There is no consensus on the need to clamp the tube when air loss stops. Opponents of the method fear the development of repeated pulmonary collapse, and supporters talk about the possibility of detecting a small “leak” of air, which the “air lock” cannot detect.

The drainage tube is removed 24 hours after air has stopped flowing through it, if (according to a chest x-ray) expansion of the lung has been achieved.

Chemical pleurodesis

■ One of the leading tasks in the treatment of pneumothorax is to prevent

rotation of repeated pneumothoraxes (relapses), but no

■ Chemical pleurodesis is a procedure in which

the pleural cavity is injected with substances leading to aseptic

pleura, which leads to obliteration of the pleural cavity.

■ Chemical pleurodesis is indicated for: patients with first and subsequent

mi VSP and patients with the second and subsequent PSP, since

Pneumothorax

no intrapleural anesthesia - at least 25 ml of 1% solution

helps prevent recurrence of pneumothorax.

Chemical pleurodesis is usually performed by insertion through

doxycycline drainage tube (500 mg in 50 ml saline)

solution) or a suspension of talc (5 g in 50 ml of physiological

solution). Before the procedure, it is necessary to carry out adequate

ra lidocaineS. After administration of the sclerosing agent, the drainage tube is closed for 1 hour.

The number of relapses after the introduction of tetracycline is 9–25%, and after the introduction of talc - 8%. Complications that can occur when talc is administered into the pleural cavity - acute respiratory distress syndrome (ARDS), empyema, acute respiratory failure - cause some concern. The development of ARDS may be associated with a high dose of talc (more than 5 g), as well as with the size of the talc particles (smaller particles undergo absorption with the subsequent development of a systemic inflammatory response); It is characteristic that cases of ARDS after the administration of talc have been reported mainly in the USA, where the particle size of natural talc is much smaller than in Europe.

Surgical treatment of pneumothorax

Objectives of surgical treatment of pneumothorax: resection of bullae

and subpleural vesicles (blebs), suturing of pulmonary defects

of tissue, performing pleurodesis.

Indications for surgical intervention:

lack of expansion of the lung after drainage

for 5–7 days;

bilateral spontaneous pneumothorax;

contralateral pneumothorax;

spontaneous hemopneumothorax;

recurrence of pneumothorax after chemical spewing

Urgent events

For tension pneumothorax it is indicated immediate tracocentesis(using a needle or cannula for venipuncture no shorter than 4.5 cm, in the 2nd intercostal space along the midclavicular line), even if it is impossible to confirm the diagnosis using radiography.

Patient education

After discharge from the hospital, the patient should avoid physical activity for a period of time. 2–4 weeks and air travel for 2–4 weeks.

The patient should be advised to avoid changes in barometric pressure (parachuting, diving).

The patient should be advised to quit smoking.

Indications for consultation with specialists

If there are difficulties in interpreting chest x-ray data, consultation with a specialist in x-ray methods is indicated.

Consultation with a pulmonologist (or intensive care specialist) and a thoracic surgeon is necessary: ​​when performing invasive procedures (installation of a drainage tube), determining indications for pleurodesis, additional measures (thoracoscopy, etc.).

Further management

Once the pneumothorax resolves, a chest x-ray is recommended.

Consultation with a pulmonologist via 7–10 days after discharge from the hospital.
