Pneumothorax can be primary spontaneous, secondary, or iatrogenic and is typically diagnosed and monitored using chest imaging. Treatment depends on factors like size, symptoms and underlying lung condition, ranging from observation to tube drainage.
Pneumothorax is the presence of air in the pleural space and can be spontaneous, due to trauma, or iatrogenic. It is classified as primary spontaneous which occurs without lung disease usually in young males, secondary spontaneous which occurs with underlying lung pathology, or traumatic. Types include closed which seals off, open with a bronchopleural fistula, and tension which increases pressure. Clinical features include chest pain and shortness of breath. Diagnosis is made with chest x-ray showing increased radiolucency. Small primary pneumothoraces may resolve on their own while secondary pneumothoraces and those with symptoms require tube thoracostomy drainage. Recurrent cases require pleurodesis or surgery.

This document discusses pneumothorax, which is the accumulation of air in the pleural space causing lung collapse. It defines pneumothorax as air in the pleural space that can occur spontaneously or from trauma. The types are described as spontaneous, open, or tension pneumothorax. Clinical manifestations include shortness of breath, chest pain, and decreased breath sounds on the affected side. Diagnosis involves history, exam, chest x-ray and blood gas analysis. Management depends on the type but may include observation, needle aspiration, chest tube placement, or surgery to repair the lung. Nursing care focuses on dressing wounds, positioning, monitoring chest tube drainage, and watching for complications like respiratory failure.
This document discusses pneumothorax and hemothorax. It defines pneumothorax as a collection of air in the pleural space, which can be spontaneous or traumatic. Tension pneumothorax is a life-threatening condition where air builds up pressure in the pleural space. Hemothorax is defined as a collection of blood in the pleural space. The document covers causes, pathogenesis, clinical presentations, and treatment approaches for pneumothorax and hemothorax.
This document discusses pneumothorax, which is the presence of air in the pleural space outside the lung. It describes different types of pneumothorax including primary spontaneous, secondary spontaneous, closed, open, and tension pneumothorax. Risk factors, clinical features, diagnosis using chest x-ray, treatment options including chest tube insertion, and postoperative management of chest drains are covered. Surgical intervention is indicated for recurrent pneumothorax or when chest drainage fails.
Lung compression or chest trauma can cause several complications including pneumothorax, hemothorax, and flail chest. Pneumothorax involves air in the pleural space collapsing part or all of the lung. Hemothorax is a collection of blood in the pleural cavity. Flail chest occurs when multiple ribs are broken, detaching a segment of the chest wall. Nursing management focuses on stabilizing the patient, draining fluid or air from the chest, controlling pain, and supporting ventilation as needed.
Pneumothorax is the presence of air in the pleural cavity, which occurs when there is a breach in the parietal or visceral pleura. It can be classified as primary or secondary, and also as acute, chronic, small, large, partial or complete. Primary spontaneous pneumothorax typically occurs in young, tall, thin males and results from a rupture of a pulmonary bleb or bulla. Management depends on factors such as size, symptoms and underlying cause, and may include observation, aspiration, tube thoracostomy, chemical or surgical pleurodesis, or thoracoscopic procedures. Complications can include failure to reexpand, recurrence, infection or respiratory failure.
This document discusses pneumothorax, which is the presence of air in the pleural space. It can be spontaneous, due to underlying lung disease or trauma, or iatrogenic due to medical procedures. The types are described as closed, open, or tension pneumothorax. Clinical features include chest pain and breathlessness. Diagnosis is made through chest x-ray or CT scan. Treatment depends on the type and severity, ranging from needle aspiration for minor cases to chest tube drainage or surgery for more severe or recurrent cases.
This document discusses pneumothorax, which is the presence of air in the pleural space. It can be spontaneous, due to trauma, or iatrogenic. Spontaneous pneumothorax is classified as primary or secondary. Primary occurs without lung disease in young males and secondary occurs with underlying lung conditions. Types include closed, open, and tension. Clinical features, investigations like CXR and CT, and treatment approaches are described depending on the type and severity of pneumothorax. Needle aspiration, tube thoracostomy, surgery, and pleurodesis are common management steps.
The document discusses various life-threatening chest injuries that may occur from thoracic trauma. It identifies injuries like tension pneumothorax, open pneumothorax, flail chest, massive hemothorax, and cardiac tamponade as immediately life-threatening injuries that must be addressed during the primary survey. It also discusses potentially life-threatening injuries like tracheobronchial injuries, pulmonary contusions, hemothorax, and blunt cardiac injuries that require identification and treatment. Physical exams, chest x-rays, and other tests can help identify these injuries, which then often require simple procedures or surgeries to treat. The overall goals are to restore normal breathing and blood flow.
Pneumothorax is the presence of air in the pleural space. It can be classified as closed, open, or tension pneumothorax. The annual incidence is around 9 per 100,000 people. Risk factors include being a tall, thin male aged 20-40 who smokes cigarettes. Symptoms include chest pain and breathlessness. Chest x-ray is used for diagnosis and can classify pneumothorax as small or large based on rim size. Needle decompression is immediately needed for tension pneumothorax. Oxygen, aspiration, chest drain insertion, and surgery are treatment options depending on the severity of the case.
This document provides information on respiratory emergencies including causes, types of chest injuries, signs and symptoms, assessments, and treatments. It discusses specific chest injuries like rib fractures, flail chest, pneumothorax, hemothorax, and cardiac tamponade. For each injury, it describes definitions, risk factors, manifestations, diagnostic procedures, nursing care, and complications. The overall document aims to define respiratory emergencies, list causes, describe patient presentations, discuss assessments, and examine various chest injuries in detail.
Neonatal pneumothorax is the accumulation of air in the pleural cavity, which can collapse the lung. It occurs most commonly in preterm infants and those with underlying lung conditions requiring ventilation support. Symptoms range from none in mild cases to respiratory distress and hypotension in severe cases. Diagnosis is confirmed by chest x-ray showing hyperlucent lung fields. Small pneumothoraces may be observed but symptomatic or tension pneumothoraces require needle aspiration or chest tube placement to re-expand the lung. Persistent pneumothoraces lasting over a week sometimes require additional interventions like HFOV. Prognosis depends on the underlying condition but early and effective treatment prevents complications.
This document provides an overview of chest trauma. It begins with the anatomy of the thorax and then discusses various types of chest injuries including pneumothorax, hemothorax, flail chest, cardiac tamponade, and traumatic aortic rupture. For each type of injury, the document describes the mechanism of injury, signs and symptoms, and treatment approaches. It emphasizes the life-threatening nature of many chest injuries and stresses the importance of rapid diagnosis and management.
Pneumothorax refers to the presence of air in the pleural space and can occur spontaneously due to ruptured blebs or as a result of trauma or medical procedures. It presents clinically as reduced breath sounds, hyperresonance to percussion, and mediastinal shift. Chest x-ray or CT scan are used for diagnosis and show hypertranslucency. Treatment involves supplemental oxygen, aspiration, or chest tube placement. Physiotherapy focuses on improving ventilation and exercise tolerance. Recurrence can be prevented through procedures like pleurodesis or thoracotomy along with smoking cessation.
This document provides an overview of pneumothorax. It begins by defining pneumothorax as air in the pleural space between the lung and chest wall. The pathophysiology section explains how a pneumothorax occurs when air leaks into the pleural space, eliminating the normal negative pressure. This can impair breathing and circulation.
The document then classifies pneumothoraces as primary spontaneous, secondary spontaneous, or traumatic. Clinical features include dyspnea and chest pain. Diagnosis involves chest x-ray or CT scan to evaluate lung collapse and estimate size. Treatment depends on pneumothorax type and size but may include observation, oxygen therapy, needle aspiration, chest tube drainage, chemical pleuro
ABDOMINAL TRAUMA in pediatrics part one.drhasanrajab
Abdominal trauma in pediatrics refers to injuries or damage to the abdominal organs in children. It can occur due to various causes such as falls, motor vehicle accidents, sports-related injuries, and physical abuse. Children are more vulnerable to abdominal trauma due to their unique anatomical and physiological characteristics. Signs and symptoms include abdominal pain, tenderness, distension, vomiting, and signs of shock. Diagnosis involves physical examination, imaging studies, and laboratory tests. Management depends on the severity and may involve conservative treatment or surgical intervention. Prevention is crucial in reducing the incidence of abdominal trauma in children.

8 Surprising Reasons To Meditate 40 Minutes A Day That Can Change Your Life.pptxHolistified Wellness
We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.

Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).
Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.

Normal pleural space = closed sac in which negative pressure is essential for normal lung expansion during breathing (simplified: space b/w lungs and chest wall)
*Remember from physics: Areas of high pressure will move into areas of lower pressure (I.e. when we exhale, we force air out of lungs, creating large area of negative pressure in pleural space, which entices air to rush back into lungs when we open mouth; inhalation = opposite, lots of positive pressure introduced into lungs, smaller negative pressure in pleural space around lungs).
“OPEN” vs. “CLOSED” chest injuries: open injuries have significant potential to compromise efficacy of pleural space and therefore respiratory function. Also potential for infection of exposed vital organs/systems, plus cavity area can pool blood quickly (internal bleeding).
Primary-smokers suggestive of subclinical disease
----------------------
primary spontaneous (no obvious underlying lung disease), secondary spontaneous (underlying lung disease), and iatrogenic pneumothoraces (which are traumatic but typically are smaller and more easily managed)
Primary spontaneous pneumothorax seems to result from rupture of a subpleural bleb, usually in an upper lobe.5 These blebs are usually multiple and have increased wall tension, allowing distention and eventual rupture. The mechanism of bleb formation remains unknown, but higher upper lobe transpulmonary pressure, local ischemia from decreased upper lobe blood flow, and subclinical emphysema-like changes have been postulated
-------------------
Primary spontaneous pneumothorax
Air in the intrapleural space without preceding trauma and without underlying clinical or radiologic evidence of lung disease
Typically in patients who are between 18 and 40 years of age
Primary spontaneous pneumothorax occurs in individuals without known lung disease and accounts for two-thirds of spontaneous pneumothoraces
Secondary spontaneous pneumothorax
Occurs in patients with underlying pulmonary structural pathology
Air enters the pleural space via distended, damaged, or compromised alveoli
May present with more serious clinical symptoms and sequelae due to comorbidity
Iatrogenic pneumothorax
Medical procedure resulting in traumatic pneumothorax (usually from a small-bore hollow needle)
Iatrogenic pneumothorax occurs secondary to a diagnostic or therapeutic procedure and is really a subset of penetrating traumatic pneumothorax.
------------------------------
Primary spontaneous pneumothorax
Spontaneous pneumothorax is heavily associated with smoking, with 80-90% of primary spontaneous pneumothorax cases occurring in smokers.
Physical height: It has been noted that typical patients tend to have a tall and thin body habitus. Whether height affects development of subpleural blebs or whether more negative apical pleural pressures cause preexisting blebs to rupture is unclear.
Valsalva results in increased intrathoracic pressure. However, contrary to popular belief, most spontaneous pneumothoraces occur while the patient is at rest.
Changes in atmospheric pressure, proximity to loud music, and low frequency noises have also been reported to be associated with pneumothorax
Familial associations have been noted in more than 10% of patients. Some are due to rare connective tissue diseases, but recently, mutations in the gene encoding folliculin (FLCN) have been described. These patients may represent an incomplete penetrance of a genetic disorder. Birt-Hogg-Dube syndrome is characterized by benign skin growths, pulmonary cysts, and renal cancers and is caused by mutations in the FLCN gene.
Secondary spontaneous pneumothorax
COPD or emphysema
Asthma
Cystic fibrosis
Interstitial lung disease
Tuberculosis
Bronchogenic or metastatic carcinoma
Pneumonia (fungal, caseating, HIV)
Collagen vascular disease including Marfan syndrome
Catamenial pneumothorax
---------------------------
The most common underlying abnormality in secondary spontaneous pneumothorax is COPD
-----------------------------------------
Regardless of the inciting event, once there is a break in the pleura, air travels down a pressure gradient into the intrapleural space until pressure equilibrium occurs with partial or total lung collapse. Altered ventilation perfusion relationships and decreased vital capacity then contribute to dyspnea and hypoxemia
flying
Iatrogenic pneumothorax occurs secondary to a diagnostic or therapeutic procedure and is really a subset of penetrating traumatic pneumothorax.
Spontaneous pneumothoraces in most patients occur from the rupture of blebs and bullae. While primary pneumothorax is defined as a lack of underlying pulmonary disease, these patients have asymptomatic blebs and bullae detected on CT scans or upon thoracotomy. Until a bleb ruptures and causes a pneumothorax, no clinical signs or symptoms are present.The pleural space has a negative pressure, with the chest wall tending to spring outward and the lung's elastic recoil tending to collapse. If the pleural space is invaded by gas from a ruptured bleb, the lung collapses until equilibrium is achieved or the rupture is sealed. As the pneumothorax enlarges, the lung becomes smaller.
The main physiologic consequence of this process is a decrease in vital capacity and partial pressure of oxygen. Young and otherwise healthy patients can tolerate these changes fairly well, with minimal changes in vital signs and symptoms, but those with underlying lung disease may have respiratory distress.
Equilibrium between intrathoracic and atmospheric pressure is immediate..
Spontaneous pneumothorax
Tachycardia (most common)
Tachypnea
Hypoxia
-----------------------
Symptoms are related to the size of the pneumothorax, rate of development, and underlying clinical status of the patient.
----------------------------------------------
Acute pleuritic chest pain occurs in 95 percent of patients and localizes to the side of the pneumothorax in >90 percent of cases. Dyspnea occurs in 80 percent of patients, and predicts a larger pneumothorax. Patients with COPD who develop a spontaneous pneumothorax may acutely decompensate, with 1 to 17 percent mortality.
Decreased breath sounds occur over the affected lung 85 percent of the time, but only 5 percent have tachypnea of more than 24 breaths/min or tachycardia of more than 120 beats/min. Hyperresonance occurs in fewer than one-third. Tracheal deviation and hemodynamic compromise are the hallmarks of tension pneumothorax that demand immediate treatment
Short-term complications of spontaneous pneumothorax include tension pneumothorax, failure to reexpand, persistent air leak, and complications related to the removal of intrapleural air, such as infection, technical errors, and reexpansion pulmonary edema
---------------------
Recurrence of pneumothorax is the major long-term complication and the reason that all patients with spontaneous pneumothorax require referral for potential definitive therapy. Primary spontaneous pneumothorax recurs in approximately 20 to 30 percent of patients and is independent of the method chosen to remove the intrapleural air
----------------
Secondary spontaneous pneumothorax recurs in 40 to 50 percent of patients
Chest radiography for evaluation of pneumothorax
Although expiratory images are thought to better depict subtle pneumothoraces (the volume of the pneumothorax is constant and hence proportionally higher on expiratory images), a randomized controlled trial revealed no difference in the ability of radiologists to detect pneumothoraces on inspiratory and expiratory images.
In patients with underlying pulmonary disease, the classic visceral pleural line may be harder to detect because the lung is hyperlucent, and little difference exists in the radiographic density between the pneumothorax and the emphysematous lung.
Ratio of lung size to hemithorax size to estimate pneumothorax size avoids the subjective underestimation of pneumothorax expressed as a percentage of previous lung volume
The size of a pneumothorax may be estimated by using the ratio of the lung diameter cubed to the hemithorax diameter cubed.
This formula assumes a constant shape of the lung when it collapses and is invalid if pleural adhesions are present.
A simple approach to classification of the pneumothorax as small or large involves measuring the distance from the apex of the lung to the top margin of the visceral pleura (thoracic cupola) on the upright chest radiograph.
Small pneumothorax: <3 cm distance to the apex
Large pneumothorax: >3 cm distance to the apex
A supine chest radiograph may depict the deep sulcus sign (very dark and deep costophrenic angle). The anterior costophrenic recess becomes the highest point in the hemithorax, resulting in an unusually sharp definition of the anterior diaphragmatic surface due to gas collection and a depressed costophrenic angle.
--------------------------------------------
CT of the thorax
When performed on primary spontaneous pneumothorax patients, CT detects multiple blebs and bullae in the setting of negative chest radiographic findings. This may not impact management, as there has been no correlation between number of blebs and recurrence.
CT can detect occult pneumothorax in patients who will require mechanical ventilation in trauma and emergency surgery settings.
CT has also been shown to be more sensitive than radiography for hemothorax and pulmonary contusion.
While the role of CT in trauma patients is evolving, it is controversial whether it significantly alters management and is not indicated in primary spontaneous pneumothorax.
CT may have a role in secondary spontaneous pneumothorax, especially to differentiate from giant bullous emphysema.
-------------------------------------------------------------------------------------
Ultrasonography
Ultrasonography can be used as a possible bedside technique to detect pneumothorax.
It may be useful in unstable patients who cannot undergo radiologic studies outside of the emergency department.
Many trauma centers are incorporating chest ultrasonography as an adjunct to the Focused Assessment with Sonography in Trauma (FAST) examination used for trauma patient screening.
Ultrasonography is operator dependent.
-------------------------------
Skin fold mimicking pneumothorax. A: AP supine chest radiograph shows opacification of the right medial lung outlined by a sharp edge (skin fold; arrows). Note that the lung peripheral to this edge is not hyperlucent, a clue that there is no pneumothorax. B: AP upright chest radiograph obtained 1 hour later no longer shows the skin fold. Redundant skin can result in skin folds on the chest radiograph, especially when the patient is supine. Changing patient positioning is often useful in differentiating a skin fold from a pneumothorax.
Pseudo-pneumothorax caused by a skin fold, scapular border, or tubing, is differentiated from true pneumothorax by looking for vascular markings inside the confines of the radiolucent area and the blending of these lines into the chest wall, rather than following the borders of a collapsed lung. Large bullae have been mistaken for pneumothoraces, but bullae and cysts have concave inner margins and rounded edges.
severe bullous COPD may mimic pneumothorax, and careful review of the CXR is needed with confirmatory CT, if the patient is stable. A thoracostomy with the chest tube inserted into a bulla mistaken for a pneumothorax results in a large pneumothorax, associated bronchopulmonary fistula, and its complications
---------------------------------------
Chest tube track mimicking pneumothorax. A: PA chest radiograph, coned to the left upper hemithorax, shows a thin curvilinear opacity paralleling the chest wall (arrows). B: AP chest radiograph obtained 1 day earlier shows a chest tube following the course of the opacity seen in (A).
Pneumothorax in a supine patient. AP supine chest radiograph shows the “deep sulcus†sign of pneumothorax on the right (curved arrow) and a basilar pneumothorax on the left (straight arrows)
---------------------------------
Pneumothorax is much more difficult to detect on a supine anteroposterior radiograph. On the anteroposterior view, a deep sulcus sign, representing a deep lateral costophrenic angle, sometimes is a clue to a pneumothorax.
The Lung Point, a Sign Specific to Pneumothorax
A patient with hard-to-detect or absent lung sliding and absence of interstitial syndrome will have an ultrasound profile of pneumothorax, i.e., a false-positive image. we can build a specific sign: with immediate and fleeting visualization at a precise location of the chest wall and along a definite line, at a precise moment of the respiratory cycle, usually inspiration, with the probe strictly motionless, the operator finds either lung sliding, lung rockets, or alteration of A lines, in an area previously observed with no lung sliding and the A-line sign, i.e., patterns that were barely suggestive of pneumothorax This sign has been called the lung point sensitivity of 66% and a specificity of 100% This sign can be explained if one considers that any lung, at the wall or not, in spontaneous or mechanical ventilation,
will slightly increase its volume on inspiration. Therefore, a lung sign will appear at the boundary area, at the precise line where the lung reaches the wall, since the lung surface in contact with the wall will increase .The poor sensitivity of ultrasound is easily explained: major, completely retracted pneumothorax will never touch the wall.
Emergency department evaluation and management of pneumothorax centers on immediate management of complications such as tension pneumothorax or ventilatory failure, and then on eliminating the intrapleural air and optimizing pleural healing.

Needle coverts it into simple pneumo…
All sides-tension pneumothorax
There is general agreement that a tension pneumothorax must be treated as an emergency by inserting a wide-bore needle or intercostal catheter (Davies, 1969), which can be connected subsequently to an underwater seal or to a valve (Knight, 1967). There is, however, considerable controversy about the treatment of cases not under tension.
--------------------------
Primary - rupture of apical pleural blebs, small cystic spaces that lie within or immediately under the visceral pleura
Nearly all patients with secondary pneumothorax should be treated with tube thoracostomy because of the lack of pulmonary reserve in these patients
----------------------------
Primary spontaneous pneumothorax
If the pneumothorax is smaller than 15% (or estimated as small, see Imaging Studies) and the patient is symptomatic but hemodynamically stable, needle aspiration is the treatment of choice.
If the pneumothorax is smaller than 15% and if the patient is asymptomatic, many consider observation to be the treatment of choice. (If the patient is admitted, administer oxygen, since this has been shown to speed resolution of the pneumothorax.)
If the pneumothorax is greater than 15% (or estimated as large, see Imaging Studies), aspiration using a pigtail catheter left to low suction or water seal is recommended.
Secondary spontaneous pneumothorax
Tube thoracostomy is the procedure of choice.
----------------------------------------
It is clearly important that treatment with high concentration oxygen should be avoided in patients with respiratory failure and in those with a tension pneumothorax. This method of treatment should probably be limited to the common primary type of spontaneous pneumothorax occurring in the absence of any generalized lung disease.
Computed tomography of the patient showing the pigtail
------------------------------------------------
The technique involves placing a small catheter either into the second anterior intercostal space in the midclavicular line or laterally at the fourth or fifth intercostal space in the anterior axillary line after local anesthesia and sterile preparation. A three-way stopcock is applied, and a 60-mL syringe is used to aspirate the pleural space until resistance is met and the patient coughs. The stopcock is closed, the tube is secured, and a chest radiograph is obtained to assure reexpansion. Aspiration of more than 4 L suggests continued air leak and failure of simple aspiration. Failure to fully expand warrants another aspiration attempt, addition of a Heimlich valve, or formal tube thoracostomy. If the procedure is successful, patients should be observed for 6 h and, if no recurrence is seen, the catheter is removed and the patient discharged with close follow-up within 24 h.
Secondary spontaneous pneumothorax
Tube thoracostomy is the procedure of choice.
Iatrogenic pneumothorax: Aspiration is the technique of choice for iatrogenic pneumothoraces because recurrence usually is not a factor. Tube thoracostomy is reserved for very symptomatic patients.
