Thoracentesis: Procedure, Recovery Time and Cost in India

A thoracentesis, also known as a pleural tap, is a medical procedure designed to remove excess fluid or air from the pleural space—the area between the lungs and the chest wall. When fluid accumulates in this space, a condition called pleural effusion can develop, which may cause lung compression and make breathing difficult. During a thoracentesis, a needle is carefully inserted into the pleural space to drain the accumulated fluid or air, providing relief and improving breathing.

This minimally invasive procedure aims to ease breathing by removing the excess fluid or air. In the following sections, you’ll learn more about what thoracentesis entails, how the procedure is performed, how to prepare for it, and the potential risks or complications associated with the procedure.

What is Thoracentesis?

Thoracentesis is a procedure that removes excess fluid from the pleural space—the area between your lungs and chest wall. This space is lined by a thin layer of tissue called the pleura, which allows your lungs to expand and contract smoothly as you breathe. A small amount of fluid between the pleura helps reduce friction, similar to how oil helps a door hinge move more easily.

Thoracentesis is often performed to relieve symptoms caused by pleural effusion, a condition in which fluid builds up in the pleural space, making it difficult to breathe. Pleural effusion can result from various medical conditions, including:

• Malignant tumors (cancer)
• Lung infections such as pneumonia or tuberculosis
• Congestive heart failure
• Cirrhosis (liver disease)

In some cases, a diagnostic thoracentesis can also help doctors identify the cause of fluid accumulation. Depending on your condition, your doctor may remove more or less fluid. The procedure typically takes 10 to 15 minutes, though it may take longer if there is a large amount of fluid. After the procedure, the fluid collected may be tested in a lab to help determine the cause of the pleural effusion.

In certain situations, your doctor may also perform a pleural biopsy, which can help identify the underlying cause of pleural effusion, though this is not routinely done. Possible causes that a biopsy may help diagnose include:

• Lung cancer or malignant pleural effusion
• Mesothelioma, a cancer of the lung lining associated with asbestos exposure
• Tuberculosis affecting the pleura

Why is Thoracentesis Performed?

Thoracentesis is performed for two main reasons:

1. Diagnostic: The procedure involves draining fluid to help determine the cause of its accumulation. This could be due to various factors, such as infection or malignancy.
2. Therapeutic: Thoracentesis is also done to relieve breathing difficulty caused by excess pleural fluid compressing the lungs. By removing the fluid, the lungs can expand more easily, making breathing less difficult.

Who Needs Thoracentesis?

Thoracentesis is performed on patients with pleural effusion to either improve breathing or help diagnose the cause of the fluid buildup. According to the American Thoracic Society, common reasons for performing a diagnostic thoracentesis include:

• Determining the cause of a new pleural effusion
• Providing relief for breathing difficulties
• Detecting cancer or managing its symptoms
• Identifying the presence of an infection

Your doctor will help determine if you are a suitable candidate for thoracentesis. In some cases, the procedure may not be recommended. Doctors are cautious about performing thoracentesis on patients who:

• Cannot be safely repositioned
• Have blood clotting disorders
• Take blood thinners
• Have recently undergone lung surgery
• Face other conditions where the risks may outweigh the potential benefits

What Conditions Can Thoracentesis Treat?

Thoracentesis is used to treat Pleural effusion, a condition where excess fluid accumulates between the lungs and the chest wall. The procedure helps relieve symptoms and allows doctors to determine the underlying cause of the fluid buildup, enabling appropriate treatment.

Pleural effusion can result from various medical conditions, including:

• Heart disease (especially heart failure)
• Cancer
• Lung infections or pneumonia (viral, bacterial, or fungal)
• Autoimmune diseases, such as systemic lupus erythematosus (SLE)
• Pulmonary embolism (blood clots in the lungs)
• Pulmonary hypertension
• Pancreatitis (inflammation of the pancreas)
• Liver or kidney disease
• Tuberculosis (TB)

Heart failure is one of the most common causes of pleural effusion.

How to Prepare for a Thoracentesis?

There is no special preparation required for thoracentesis, but it’s important to discuss any concerns or questions with your doctor beforehand. Your doctor will provide specific instructions to help you prepare for the procedure. You may be asked to:

• Stop taking certain medications for a specified period before and after the procedure.
• Arrange for someone to drive you home after the procedure.

Be sure to inform your doctor if you:

• Have a bleeding or clotting disorder.
• Take aspirin, blood thinners, or any other medications (including over-the-counter drugs, vitamins, or supplements).
• Are pregnant or planning to become pregnant?
• Have allergies to latex, tape (adhesives), or any medications, including anesthetics.

What Happens During a Thoracentesis Procedure?

What Happens During a Thoracentesis Procedure?

Thoracentesis can be performed in a hospital or doctor’s office. While the procedure is typically done while you are awake, you may be given a sedative. If sedated, you will need someone to drive you home afterward. The procedure usually takes 10 to 15 minutes, though it may take longer if there is a significant amount of fluid to drain.

Before the Procedure: Before thoracentesis, your doctor will check your blood pressure and oxygen levels using a small device on your finger. Imaging techniques such as X-ray, ultrasound, or CT scans will be used to locate and assess the amount of fluid in the pleural space, ensuring the needle is inserted correctly.

You will need to remove any jewelry and change into a gown with an open back. You will be asked to sit with your arms resting on a table or, if you cannot sit, lie on your side. The doctor will clean the area with antiseptic and apply a local anesthetic to numb the site.

During the Procedure: You will typically remain awake during thoracentesis. Your doctor may ask you to hold your breath or stay still while they perform the procedure. You may feel pressure or discomfort as the fluid is drained, but it should not be painful. If you experience chest pain, shortness of breath, or dizziness, inform your doctor immediately.

• You will be positioned in a way that allows the doctor to access the pleural space. This position helps spread out the space between your ribs for easier needle insertion.
• Your vital signs, including heartbeat and blood pressure, will be monitored throughout the procedure.
• You may receive oxygen through a mask or nasal cannula.
• After numbing the area, the doctor will insert a needle into the pleural space, which may cause a brief pinch. They may wait a moment to ensure the area is properly numb before proceeding.
• A second needle may be used to drain the fluid, guided by ultrasound. As the fluid drains, you may feel pressure or have the urge to cough as your lungs re-expand.
• Once all the fluid is drained, the needle is removed, and the site is bandaged. A follow-up X-ray may be taken to check for any complications.

After the Procedure: Following thoracentesis, your doctor will monitor your vital signs and may perform another X-ray to ensure everything is normal. If your blood pressure, oxygen levels, and breathing are stable, you can typically go home the same day. You may cough for up to an hour afterward, which helps your lungs recover.

While you can resume most activities soon after, your doctor may recommend avoiding strenuous exercise for a few days. They will also explain how to care for the puncture site, and you should contact them if you notice any signs of infection, such as:

• Difficulty breathing
• Blood in sputum
• Fever or chills
• Pain when breathing deeply
• Redness, swelling, or bleeding at the injection site

The fluid drained during thoracentesis is usually sent to a lab for testing to identify possible causes of the pleural effusion, such as infections or cancer. Your doctor will inform you of the results and their implications for your health.

Recovery: The recovery time for thoracentesis is generally short, with most patients able to leave the hospital on the same day. The doctor will give you instructions on how to care for the puncture site at home. If necessary, you can take acetaminophen to manage any discomfort. Heavy activity should be avoided for about 48 hours, but you can typically remove the bandage after 24 hours.

Complications: Though rare, complications can occur during thoracentesis. Possible risks include:

• Bleeding: If the needle punctures a blood vessel, bleeding may occur, though it usually resolves on its own.
• Infection: Bacteria could enter through the skin during the procedure, leading to an infection.
• Lung collapse (pneumothorax): The needle may accidentally puncture the lung, causing air to escape and potentially leading to a collapsed lung.
• Pulmonary edema: If too much fluid is drained too quickly, it can cause fluid to build up in the lungs.
• Damage to the liver or spleen: Though rare, this can occur if the needle is misplaced.

The use of ultrasound or CT imaging to guide the procedure has significantly reduced the risk of complications. Studies show that ultrasound-guided thoracentesis has a complication rate of less than 1.2%, compared to a 10-18% risk of a collapsed lung without imaging guidance.
