What is the medical term for puncturing the space between the ribs to withdraw fluid from the chest cavity?

• A. Pleurocentesis
• B. Thoracentesis
• C. Pneumothorax
• D. Cardiocentesis

Answer: (A)

The action of puncturing the space between the ribs to withdraw fluid from the chest cavity is called thoracentesis. This procedure targets the pleural space, the thin gap between the lungs and chest wall, accessed through the intercostal space with a needle or catheter to remove pleural fluid. While pleurocentesis is a term you might encounter, the commonly used and most recognized term for this purpose in exams and clinical practice is thoracentesis. Pneumothorax refers to air in the pleural space (a condition, not a procedure), and cardiocentesis would involve accessing the heart. Thoracentesis is performed to diagnose or relieve symptoms from pleural effusion, and it’s done with attention to patient position, local anesthesia, and awareness of risks like pneumothorax or bleeding.
