Thoracentesis

Thoracentesis is a procedure that removes excess fluid from the space between your lungs and chest wall (pleural space). When fluid accumulates in this space, it can make breathing difficult. During the procedure, your doctor numbs a small area of your chest wall and carefully inserts a thin needle between your ribs to remove the fluid. This fluid can then be tested to determine what's causing the buildup.

The procedure typically takes 15-30 minutes, and most patients experience immediate relief from breathing difficulties. While you might feel some pressure during the procedure, the use of local anesthesia ensures minimal discomfort.
