Thoracocentesis & Pleural Tap Procedure in Delhi

Thoracocentesis (Pleural Tap)

Thoracocentesis is also called as pleural tap. It is a medical procedure where a needle is inserted into the pleural space, the space between the lungs and chest wall to remove excess fluid. It is done for both diagnosis, finding the cause of the fluid and treatment relieving symptoms like breathlessness.

Why is it Done?

Pleural fluid build-up (pleural effusion) can occur due to:

Infections (pneumonia, tuberculosis, empyema)
Heart failure
Liver or kidney disease
Cancer (lung, breast, mesothelioma, metastatic cancers)
Pulmonary embolism
Autoimmune diseases (e.g., rheumatoid arthritis, lupus)

Symptoms

Shortness of breath
Chest pain
Persistent cough
Unexplained fever
Abnormal chest X-ray or ultrasound showing fluid in the chest

How to Prepare for the test?

Fasting is usually not required unless combined with other procedures.
Inform your doctor about any blood thinners you take (aspirin, warfarin, and clopidogrel).
You should wear loose clothing.
A chest ultrasound may be done beforehand to find the safest spot for fluid removal.

How is it Done?

Patient sits upright, leaning slightly forward.
The skin is cleaned and local anesthesia is given to numb the area.
A thin needle or catheter is inserted into the pleural space, guided by ultrasound.
Fluid is drained into a sterile container, sometimes only a small amount for diagnosis, or more if done to relieve breathlessness.
The needle is removed, and a dressing is applied.

Frequently Asked Questions (FAQs)

1. Is thoracocentesis painful?

You may feel a slight stinging from the anesthesia and some pressure when fluid is removed, but it’s usually well-tolerated.

2. How long does it take?

Around 10–30 minutes, depending on the amount of fluid.

3. Will the fluid come back?

If the underlying cause is not treated (e.g., cancer, heart failure), fluid may return and require repeat drainage.
