Which condition is indicated for thoracocentesis or thoracostomy?

• A. Asthma attack
• B. Tension pneumothorax
• C. Heart failure
• D. Cardiac arrest

Answer: (B)

Thoracocentesis and thoracostomy are both procedures used to relieve pressure in the thoracic cavity and are specifically indicated in cases of tension pneumothorax. In tension pneumothorax, air accumulates in the pleural space and exerts pressure on the lung and mediastinal structures, potentially leading to respiratory failure and cardiovascular collapse. This condition can arise from trauma, mechanical ventilation, or spontaneous rupture of lung tissue. Performing a thoracostomy (chest tube insertion) or thoracocentesis (needle decompression) effectively allows for the escape of trapped air, thereby restoring normal intrathoracic pressure, allowing the lung to re-expand, and improving venous return to the heart. Prompt intervention is critical to prevent fatal outcomes, which is why these procedures are lifesaving measures in the context of a tension pneumothorax. Other conditions like asthma attack, heart failure, and cardiac arrest do not typically require these invasive procedures as first-line management. While they may require different urgent interventions, the presence of a tension pneumothorax specifically necessitates a thoracocentesis or thoracostomy to address the potentially life-threatening increase in thoracic pressure.
