Thoracentesis is a minimally invasive procedure that uses a needle (and sometimes a small catheter) to safely drain excess fluid or air from the space around your lungs (the pleural cavity). It’s done while you’re awake and guided by ultrasound. This fluid can then be tested for infection, cancer, or inflammation and removing it often improves symptoms like chest tightness and shortness of breath.

Who Is It For?

Ideal patients include those who:

• Feel breathless or tight-chested due to fluid buildup
• Had fluid re-accumulation despite ongoing treatment
• Need fluid analysis to investigate infections, cancer, or heart/lung disease

Key Benefits:

• Diagnostic & Symptomatic – Helps confirm a cause (infection, cancer) and often immediately relieves breathing issues
• Minimally Invasive – Just a needle or thin catheter under local anesthesia, sometimes in one quick session
• Rapid Recovery – Most patients go home the same day; discomfort is mild and brief 

Common Uses:

• Drain splashes of fluid or air in the lungs (pleural effusion, pneumothorax)
• Investigate causes like infection, lung cancer, heart failure, or TB
• Repeated fluid removal can be managed with a small catheter tube if needed
