Thoracocentesis is defined as which procedure?

• A. puncture of the chest wall with a needle to obtain fluid or air from the pleural cavity
• B. puncture of the abdomen to obtain fluid
• C. puncture of the chest wall to obtain muscle biopsy
• D. incision to drain the chest cavity

Answer: (A)

Accessing the pleural space by needle puncture through the chest wall to remove fluid or air defines thoracocentesis. This procedure is used to diagnose or relieve conditions like pleural effusion or pneumothorax and is performed with aseptic technique and local anesthesia, usually targeting a specific intercostal space to minimize risk. It differs from tapping the abdomen to obtain fluid (abdominocentesis), taking a muscle biopsy from the chest wall, or surgically incising to drain the chest cavity (which would be a thoracostomy or chest drain), which involve different approaches and purposes.
