Questions and Answers

What is a characteristic of a closed pneumothorax?

Pleural pressure is equal to atmospheric pressure

There is continuous communication between the lung and pleural cavity

The opening in the lung is very large, hence it doesn't heal rapidly

The opening in the lung is very small, hence it heals rapidly (correct)

What is a sign of a pneumothorax?

Shift of the mediastinum to the same side

Hyper-resonance on percussion (correct)

Dullness on percussion

Decreased venous return to the heart

In which situation is needle aspiration of pneumothorax more likely?

The air occupies <20% of the hemithorax

The patient has a traumatic pneumothorax

The patient has a secondary spontaneous pneumothorax and is clinically unstable

The patient has a primary spontaneous pneumothorax and is clinically stable (correct)

Study Notes

Pneumothorax and Pleural Effusion

Pleural infection is a common cause of pyo-pneumothorax, which is secondary to pressure fistula.

Clinical Presentation

Symptoms depend on the amount of air leakage, extent of lung collapse, rate of development, etiology, and underlying clinical status of the patient.
Common symptoms include chest pain, dyspnea, and dry or nonproductive cough.
Simple pneumothorax may present with no symptoms and is found incidentally on a chest radiograph.
Patients with spontaneous pneumothorax secondary to preexisting lung disease may have a dramatic presentation.
Premature neonates on mechanical ventilation may develop pneumothorax due to positive pressure and respiratory system compliance.

Radiological Diagnosis

Chest X-ray shows:
- Hyper-translucency between the lung and thoracic cage.
- Sharp border of the collapsed lung.
- Shifting of mediastinum to the opposite side.
Chest US and Chest CT may also be used for diagnosis.

Complications

Cardiac tamponade
Cardiopulmonary arrest
Hemothorax
Pneumopericardium
Pneumomediastinum
Shock
Tension pneumothorax

Treatment

Surgical treatment includes:
- Supplemental O2 to facilitate pleural air resorption.
- Aspiration to aspirate air in the pleural cavity.
- Tube thoracostomy connected to a water seal device ± suction.
- Thoracoscopy (VATS) for mechanical pleurodesis.
Large or complicated pneumothorax requires hospitalization and direct mechanical evacuation of pleural air.
Clinically stable patients with primary spontaneous pneumothorax can be treated with needle aspiration.
Clinically unstable patients and most patients with underlying lung disease require chest tube insertion.
Traumatic pneumothorax requires immediate decompression with needle thoracostomy followed by tube thoracostomy.

Physiotherapy

Aims to improve distribution of ventilation, reinflate collapsed lung areas, increase oxygenation, improve exercise tolerance, and maintain airway clearance.
Gentle coughing can be performed in small pneumothorax.
Large pneumothorax requires increase in lung expansion, allowing air entry during inspiration and leak during expiration, and decreasing venous return to the heart.
