What should I do before thoracentesis?
Before a thoracentesis, a chest ultrasound will be done to identify the exact location of the pleural effusion. An ultrasound is preferred because it is more accurate in determining the location of the effusion and the distance from the skin to the fluid collection than a chest X-ray or physical examination.

What is thoracentesis?
Thoracentesis is a procedure to remove fluid or air from around the lungs. A needle is put through the chest wall into the pleural space. The pleural space is the thin gap between the pleura of the lung and of the inner chest wall. The pleura is a double layer of membranes that surrounds the lungs. Inside the space is a small amount of fluid. The fluid prevents the pleura from rubbing together when you breathe. Excess fluid in the pleural space is called pleural effusion. When this happens, it’s harder to breathe because the lungs can’t inflate fully. This can cause shortness of breath and pain. These symptoms may be worse with physical activity.

What is thoracentesis procedure?
Thoracentesis is a procedure that is performed to remove fluid from the thoracic cavity. This can be done for both diagnostic and therapeutic purposes. A potential space exists in the left and right side of the chest cavity between the inner chest wall and lung. In healthy individuals, a trace amount of fluid is found in this space and provides lubrication between the lung parenchyma and musculoskeletal structures of the rib-cage during expansion and recoil. However, excess fluid is pathological. The volume of excessive fluid, the rate of accumulation, the cellular content of the fluid, and the chemical composition of the fluid are all used to guide the management and the differential diagnosis of the underlying etiology. This activity reviews the indications, contraindications, and techniques involved in performing thoracocentesis and highlights the role of the interprofessional team in the care of patients undergoing this procedure.

Why is ultrasound important in thoracentesis?
If using a sterile probe cover, thoracentesis can be facilitated by ultrasound guidance, improving landmark location and site selection.
