Pneumocentesis is a medical procedure involving the aspiration or withdrawal of air or gas from the pleural cavity, which is the space between the membranes that surround the lungs and line the chest cavity. This procedure is typically performed to alleviate conditions such as pneumothorax (accumulation of air in the pleural space), allowing the lung to re-expand and restore normal respiratory function.
Pneumocentesis is carried out using a specialized needle or catheter inserted through the chest wall into the pleural cavity under controlled conditions, often guided by imaging techniques such as ultrasound or fluoroscopy. The removed air or gas may be analyzed for diagnostic purposes or to monitor treatment effectiveness. Pneumocentesis requires expertise and precision to minimize risks and ensure patient safety. Pneumocentesis carries risks such as pneumothorax, bleeding, and infection, so it is typically only conducted when clinically necessary.
