Pleurodesis

What this procedure is

Pleurodesis is a medical procedure used to seal the space between your lung and your chest wall. This area is called the pleural space. Normally, this space is very thin and contains a tiny amount of fluid to help the lungs move smoothly as you breathe. However, if too much fluid or air gets into this space, it can make it hard for the lung to expand.

During the procedure, a clinician uses a special medicine or a physical method to create mild irritation on the surfaces of the lung and chest wall. This irritation causes the two layers to stick together, closing the gap. By sealing this space, the procedure helps prevent fluid or air from building up there in the future.

What it treats or fixes

This procedure is often used to manage conditions that cause the pleural space to fill up repeatedly. These include:

• Pleural effusion: This is a buildup of extra fluid around the lung that can cause shortness of breath or chest discomfort.
• Pneumothorax: This is a collapsed lung, which happens when air leaks into the space around the lung and pushes against it.

The main goal of pleurodesis is to improve your comfort and breathing. By closing the space, your clinician aims to stop fluid or air from returning. This may reduce the need for frequent hospital visits or repeated procedures to drain the fluid.

How common it is & where it's done

Pleurodesis is a well-established procedure used in hospitals across North America. It is a common option for patients who have chronic lung issues or certain conditions that cause fluid to return even after it has been drained.

The procedure can be performed in a few different settings depending on your specific needs:

• At the bedside: A clinician may perform the procedure in a hospital room using a small tube (chest tube) that is already in place.
• In an operating room: Sometimes, it is done during a minimally invasive surgery, such as Video-Assisted Thoracoscopic Surgery (VATS), while you are under anesthesia.

Your care team will determine the best location and method based on your overall health and the specific reason for the procedure.

Recovery: What to Expect

After the procedure, you will usually stay in the hospital for a few days so your care team can monitor your progress. A chest tube—a thin, flexible tube—will remain in your chest for a short time to drain any extra fluid or air. Your clinician will remove this tube once your lung is staying expanded on its own.

During recovery, your clinician may encourage you to:

• Use a breathing device: You may be asked to use a tool called a spirometer to help you take deep breaths and keep your lungs clear.
• Manage discomfort: It is normal to feel some soreness around the tube site. Your care team will provide medicine to keep you comfortable.
• Move around: You might be asked to change positions in bed or take short walks to help your lungs heal.

Before you go home, your team will explain how to care for the small incision site. You should call your clinician if you notice a high fever, sudden shortness of breath, or chest pain that feels new or different.

Risks & Possible Complications

Pleurodesis is a common procedure, but like any medical treatment, it has some risks. Your clinician will talk with you about these before the procedure to make sure you feel prepared.

• Pain: This is the most common side effect. It is usually temporary and managed with standard pain relief medicine.
• Fever: Some people develop a mild fever shortly after the procedure as the body reacts to the medicine used to seal the lung space.
• Infection: There is a small risk of infection at the site where the chest tube was placed.
• Fluid Return: In some cases, the lung surfaces do not stick together perfectly, and fluid or air may begin to collect again over time.

Outcomes & Long-Term Results

The main goal of pleurodesis is to help you breathe more easily and stay out of the hospital. By closing the empty space between the lung and the chest wall, the procedure prevents fluid or air from building up and pressing on your lung.

For many people, this procedure is very successful and provides long-term relief from shortness of breath. While it does not always treat the underlying cause of the fluid, it is an effective way to manage the symptoms and improve your daily comfort. Most patients find they can return to their normal activities once the initial healing period is over.

Emotional Support & Reassurance

It is natural to feel a bit nervous about a procedure involving your chest and breathing. Please know that pleurodesis is a standard treatment designed to help you feel better and remain more active. Your medical team performs these procedures frequently and is there to ensure you are safe and comfortable.

Focusing on the positive outcome—breathing with less effort—can help ease your mind. If you feel anxious, do not hesitate to share your feelings with your nurses or clinician. They can provide more information and support to help you feel confident during your recovery.

Why doctors recommend it

Your clinician may recommend pleurodesis if you have a condition where fluid or air keeps filling the pleural space, which is the thin gap between your lung and your chest wall. When this space fills up, it can prevent your lung from expanding fully, making it difficult to breathe.

This procedure is often suggested for people with a recurrent pleural effusion (fluid that keeps coming back) or a pneumothorax (a collapsed lung). By using a special medicine or a physical process to create mild inflammation, the procedure causes the lung to stick to the chest wall. This closes the empty space so that fluid or air no longer has a place to collect.

Urgent vs planned treatment

In many cases, pleurodesis is a planned procedure. If you have a chronic condition that causes fluid to build up slowly over time, your clinician may schedule the treatment to help manage your symptoms and improve your comfort. This allows you and your care team to prepare in advance.

In other situations, the treatment may be more urgent. For example, if a lung collapses suddenly and does not stay inflated on its own, your clinician may decide to perform pleurodesis sooner. This is done to stabilize the lung and prevent another collapse from happening shortly after the first one is treated.

Goals of treatment

The main goal of pleurodesis is to improve your quality of life by making it easier to breathe. By sealing the pleural space, the procedure aims to achieve the following:

• Prevent recurrence: Stopping fluid or air from building up in the same spot again.
• Symptom relief: Reducing the shortness of breath and chest pain caused by lung compression.
• Stability: Helping the lung stay fully expanded against the chest wall.

Success means you may no longer need frequent procedures to drain fluid from your chest. While pleurodesis does not always treat the original cause of the fluid or air, it is a common way to manage the symptoms and help you stay more active and out of the hospital.

Who may benefit

Pleurodesis is often recommended for people who have fluid or air that keeps building up in the space around their lungs. This space is called the pleural cavity. When too much fluid (effusion) or air (pneumothorax) collects there, it can make it very hard to breathe and cause chest pain.

Your clinician may suggest this procedure if you have a condition that causes fluid to return even after it has been drained. This is common in certain types of cancer or chronic lung issues. By sealing the space between the lung and the chest wall, the procedure helps the lung stay expanded and prevents fluid from crowding the area again.

When it may not be the right option

This procedure is generally not an option if the lung cannot expand enough to touch the chest wall. This is sometimes called a trapped lung. Because the goal is to make the two layers of tissue stick together, they must be able to reach each other for the treatment to work.

Your care team might also look for other options if there is an active infection in the chest or if your overall health makes a medical procedure difficult. In some cases, a different approach, like a small tube that stays in place to drain fluid at home, might be a better fit for your lifestyle and goals.

Questions to ask your care team

Deciding on a procedure is a big step. You may want to bring a list of questions to your next appointment to help you feel more prepared and informed about your care:

• What is the main goal of this procedure for my specific condition?
• Will this be done as a surgery or by putting medicine through a small tube?
• How long will I likely need to stay in the hospital afterward?
• What are the chances that the fluid or air will come back after the procedure?
• Are there other ways to manage my symptoms that we should consider first?

In the procedure room

You will typically be in a hospital setting, such as a specialized procedure room or your hospital bed. The medical team will help you get into a comfortable position, which often involves lying on your side or sitting up and leaning forward over a table. The area of your chest being treated will be cleaned and covered with sterile drapes to keep the environment safe and clean.

High-level steps

The main goal of this procedure is to seal the space between your lung and your chest wall. Your clinician will follow these general steps:

• Drainage: If it hasn't been done already, a thin, flexible tube called a chest tube is inserted to drain any extra fluid or air from around the lung.
• Medicine delivery: Once the lung is expanded, a medical substance (called a sclerosing agent) is guided through the tube. Common substances include sterile talc or certain antibiotics.
• Bonding: This substance causes a mild, controlled irritation. This helps the lining of the lung stick to the chest wall, which prevents fluid or air from building up in that space again.

Anesthesia and pain control

Your clinical team will take steps to keep you as comfortable as possible. They usually apply a local anesthetic to numb the skin and deeper tissues where the tube is placed. You may also receive medicine through an IV to help you feel relaxed or sleepy.

Because the medicine used to seal the lung can sometimes cause a stinging sensation or pressure, your clinician may also put numbing medicine directly into the chest tube before the procedure begins. This helps manage discomfort from the inside.

Monitoring and safety steps

Throughout the procedure, the medical team will monitor your vital signs, including your heart rate, blood pressure, and oxygen levels. They may use an ultrasound or X-ray to confirm that the fluid has been drained and that the lung is in the correct position to bond with the chest wall.

These safety checks help the clinician ensure the medicine is reaching the right areas. In some cases, they may ask you to change positions occasionally to help the medicine spread evenly around the lung.

Immediately after the procedure

After the medicine is delivered, the chest tube usually stays in place for a period of time. This allows any remaining fluid to drain while the lung and chest wall begin to stick together. The tube is typically connected to a drainage canister.

You might feel some soreness in your chest or a mild fever, which are common signs that the body is responding to the treatment. Your team will monitor your breathing and may use follow-up X-rays to check your progress.

Typical procedure length

The actual process of putting the medicine through the chest tube is relatively quick, often taking about 10 to 30 minutes. However, the total time you spend in the procedure room can be longer. This is because the team needs time to drain the fluid beforehand and ensure you are stable and comfortable afterward.

Common approaches (open vs minimally invasive)

Clinicians choose the best method based on your overall health and the specific lung condition being treated. The two main ways to perform pleurodesis are through a bedside procedure or through surgery.

• Bedside chemical pleurodesis: This is a common, less invasive approach. A doctor places a plastic tube (chest tube) between your ribs to drain fluid or air. Once the lung has re-expanded, they put a medicine—called a sclerosing agent—through the tube to help the lung stick to the chest wall.
• Surgical pleurodesis (VATS): Video-Assisted Thoracoscopic Surgery is a minimally invasive operation. A surgeon makes small cuts and uses a tiny camera to see inside the chest. They may blow a powder (like talc) into the space or gently scratch the lining (mechanical abrasion) to create the necessary stickiness.
• Open surgery (Thoracotomy): This involves a larger cut to access the lung directly. It is rarely used today unless minimally invasive options are not possible or have failed.

Partial vs total

The goal of pleurodesis is usually "total"—meaning the doctor wants the entire surface of the lung to stick to the chest wall. This prevents fluid or air from building up anywhere in that space again. For the procedure to work well, the lung must be able to expand fully to touch the chest wall.

In some cases, a "partial" result may happen if the lung is held down by scar tissue and cannot expand completely. If the lung cannot reach the chest wall at all (a condition called trapped lung), pleurodesis is often not applicable. In these situations, your clinician might suggest a different treatment to manage the fluid.

Revision or repeat procedures

Pleurodesis is generally successful, but it does not always work permanently. If the lung does not stick properly or if fluid returns, the procedure may need to be repeated. A "redo" procedure might involve switching methods, such as moving from a bedside chemical approach to a surgical one.

If a repeat procedure is not the right choice, your clinician may recommend an indwelling pleural catheter. This is a small tube that stays in place to let you drain fluid at home, rather than trying to seal the space again.

Tests and imaging that may be done

Before the procedure, your healthcare team needs to see exactly how much fluid or air is around your lung. This helps them confirm that your lung is capable of expanding and helps them plan the safest spot to place the tube.

• Chest X-ray or CT scan: These images provide a clear view of the pleural space (the area between the lung and the chest wall).
• Ultrasound: Your clinician may use an ultrasound at your bedside to guide them. This helps locate the best entry point for the procedure.

Medication adjustments

Your care team will review your current medication list to ensure your safety. It is important to tell them about everything you take, including vitamins, supplements, and over-the-counter drugs.

Certain medications, such as blood thinners, might need to be paused briefly to lower the risk of bleeding. However, you should not make changes on your own. Only stop medicines if your clinician instructs you to do so. They will tell you exactly when to take your last dose and when you can restart them.

Day-before and day-of instructions

To help the procedure go smoothly, your clinician will provide a checklist of instructions. You will also have a chance to discuss the risks and benefits of the treatment before signing a consent form.

• Food and drink: You may be asked not to eat or drink for a specific time before the procedure, especially if you will receive medicine to help you relax (sedation).
• Pain control: The team will explain how they will keep you comfortable. This usually involves local numbing medication (lidocaine) for the skin and sometimes additional medicine to manage pain or anxiety.
• Clothing: Wear loose, comfortable clothing. You will likely change into a hospital gown for the procedure.

General surgical risks

Pleurodesis is a common procedure, but like any medical treatment, it carries some general risks. Your care team takes specific safety measures to minimize these issues.

• Infection: There is a small chance of infection at the site where the tube enters the skin or inside the chest cavity (pneumonia or empyema).
• Bleeding: Minor bleeding may occur during the procedure. Significant bleeding (hemorrhage) is less common but possible.

Procedure-specific complications

Because pleurodesis works by creating inflammation (irritation) to stick the lung to the chest wall, some side effects are actually a result of the medication doing its job.

• Pain and fever: These are the most common side effects. The chemical agent used to seal the lung space causes inflammation, which often leads to chest pain and a fever.
• Breathing difficulties: Some patients experience shortness of breath. In rare cases, if a collapsed lung expands too quickly, fluid can build up in the lung tissue (re-expansion pulmonary edema).
• Procedure failure: Sometimes the lung layers do not stick together fully. This often happens if the lung is "trapped" and cannot expand enough to touch the chest wall. If this occurs, fluid or air may build up again.

How complications are treated

Most side effects are temporary and can be managed while you recover. Your clinical team will monitor your breathing and vital signs closely.

• Managing comfort: Doctors typically prescribe medication to help control chest pain and lower fever while your body heals.
• Addressing infection: If signs of an infection appear, your clinician may treat it with antibiotics.
• Next steps if fluid returns: If the pleurodesis does not work, your doctor may suggest repeating the procedure or trying a different approach, such as placing a long-term catheter that allows you to drain fluid at home.

Pain control medicines

Pleurodesis works by causing a controlled irritation between the lung and the chest wall. Because this process can be uncomfortable, your clinician may use several types of medicine to keep you at ease. They might use local anesthetics, which are numbing medicines like lidocaine, injected directly into the area around the lung.

Your care team may also provide pain relief through an IV or in pill form. These options often include:

• NSAIDs: Common anti-inflammatory medicines that help reduce swelling and pain.
• Opioids: Stronger pain relievers used for more significant discomfort.
• Acetaminophen: A standard over-the-counter pain reliever often used for mild aches.

Your clinician will tailor the pain management plan to your specific health history. It is important to mention any past reactions to pain medications or allergies you may have.

Antibiotics

Antibiotics are medicines used to fight infections caused by bacteria. While they are not always required for every pleurodesis, your clinician may prescribe them if you have an existing infection in the pleural space (the area around the lungs), such as an empyema, which is a buildup of pus.

In some cases, antibiotics might be given as a precaution to prevent an infection from starting while a chest tube is in place. Your medical team will monitor you closely for signs of fever or redness to determine if these medicines are necessary for your recovery.

Blood thinners and clot prevention

Blood thinners, also called anticoagulants, are medicines that help prevent dangerous blood clots. If you are already taking these for another condition, your clinician may give you specific instructions on when to stop taking them before your procedure to help prevent excess bleeding.

After the pleurodesis is finished, your care team will decide the best time for you to restart these medications. They will balance the need to prevent clots with the need to ensure your body is healing properly. Always tell your clinician about all the supplements and blood-thinning medicines you use to ensure a safe treatment plan.

Emergency warning signs

While recovery is usually steady, some symptoms indicate a serious reaction or a complication affecting your lungs. You should seek immediate emergency care (call 911 or go to the nearest emergency room) if you experience:

• Severe shortness of breath: Struggling to breathe or feeling like you cannot get enough air.
• Sudden chest pain: Sharp or crushing pain that happens suddenly or gets much worse quickly.
• Coughing up blood: Coughing up bright red blood (more than just a streak in mucus).
• Signs of shock: Feeling very dizzy, confused, faint, or having a rapid heartbeat.

Call your surgeon or clinic if…

Contact your healthcare provider if you notice changes that are not emergencies but suggest your recovery is off track. Your clinician may want to check for signs of infection or ensure the procedure was successful. Call if you have:

• Fever: A temperature higher than 100.4°F (38°C) or chills.
• Incision issues: Redness, warmth, increasing swelling, or pus draining from the area where the chest tube was placed.
• Unmanaged pain: Chest pain that is not relieved by your prescribed pain medicine.
• Returning symptoms: If you feel the same shortness of breath you had before the surgery, it could mean fluid or air is building up again.

Expected vs concerning symptoms

It can be hard to tell what is normal after pleurodesis because the procedure intentionally creates inflammation (irritation) to help the lung stick to the chest wall. Knowing the difference can help you stay calm.

• Expected: It is common to feel chest soreness or pleuritic pain (pain when taking a deep breath). This is often a sign that the medication or talc used during surgery is working to seal the space. Most people also feel tired for a few days.
• Concerning: Pain that gets significantly worse instead of better over time is not expected. Likewise, while some soreness is normal, difficulty breathing while resting is a concerning sign that requires medical evaluation.

Non-surgical treatments

Before recommending pleurodesis, your clinician may try other ways to manage fluid or air around the lungs. One common choice is thoracentesis, where a needle is used to drain fluid. This often helps you breathe better right away, but the fluid may come back over time.

Another alternative is an indwelling pleural catheter (IPC). This is a thin, flexible tube placed in the chest that stays there for a while. It allows you to drain fluid at home using a small vacuum bottle. This can be a helpful option for those who prefer to manage their symptoms without a hospital stay.

Watchful waiting

If your symptoms are mild, your clinician might suggest watchful waiting. This means they will monitor your condition closely without performing a procedure right away. This is often used for small amounts of fluid or air that are not causing significant shortness of breath or pain.

During this period, you may need regular imaging tests, such as chest X-rays. These tests help the medical team see if the fluid is being absorbed by the body on its own. If the fluid or air stays the same and you feel well, you might avoid more invasive treatments entirely.

When surgery becomes the best option

Surgery may become the best choice if other treatments fail to keep the lung expanded or if fluid keeps returning. If the fluid buildup is caused by a condition that creates a thick layer of scar tissue over the lung, surgery may be needed to remove that layer so the lung can inflate properly.

Your clinician may also recommend surgery if you have a persistent air leak or if you have a high risk of the problem happening again. Surgical pleurodesis is often considered when a more permanent fix is needed to improve your quality of life and prevent frequent hospital visits for drainage.

Hospital services that commonly perform this surgery

Pleurodesis is a procedure used to treat a collapsed lung or a buildup of fluid around the lungs. Your clinician may refer you to a Pulmonology department, which focuses on lung health, or a Thoracic Surgery department, which specializes in operations inside the chest. These teams have the specialized equipment needed to perform the procedure safely.

In some cases, the procedure is performed by Interventional Radiology. These specialists use medical imaging, like X-rays, to guide a small tube into the chest. If the procedure is being done because of an underlying illness like cancer, the Oncology (cancer care) team will often coordinate closely with the surgical team to manage your overall care.

Patient resources and support services

After the procedure, Respiratory Therapists are often available to help you with breathing exercises. These exercises are designed to help your lungs expand fully and stay clear as you heal. They may also provide tools like an incentive spirometer, which is a small device that helps you practice deep breaths.

Many hospitals provide access to Pain Management services. These specialists work to ensure you are comfortable during your recovery. Additionally, Social Workers or patient navigators can help you arrange for any equipment you might need at home and can connect you with local support groups for people with chronic lung conditions.

Questions for choosing where to have surgery

Choosing the right facility can help you feel more confident about your care. You may want to ask your care team the following questions when deciding where to have your procedure:

• How many pleurodesis procedures does this hospital perform each year?
• Is there a dedicated team of lung specialists and thoracic surgeons on-site?
• What kind of support is available if I have questions or concerns after I am discharged?
• Does the facility have specialized respiratory therapists to help with my recovery?
• Will my care be coordinated between my primary doctor and the hospital specialists?

Conditions commonly treated by this procedure

Pleurodesis is often used to manage a condition called pleural effusion. This is when too much fluid builds up in the pleural space, which is the thin area between your lungs and your chest wall. Your clinician may suggest this procedure if the fluid buildup is caused by certain illnesses, such as cancer, and keeps coming back after being drained.

It is also used for a pneumothorax, which is the medical term for a collapsed lung. This happens when air leaks into the space around the lung, making it hard for the lung to expand properly. The procedure is typically considered when these issues happen repeatedly or do not get better with other treatments.

Related symptoms people search for

People looking into this procedure often experience symptoms that affect their breathing. These may include:

• Shortness of breath: Also known as dyspnea, this happens because the fluid or air around the lung prevents it from filling up completely with air.
• Chest pain: This may feel like a sharp or aching sensation that often gets worse when you take a deep breath or cough.
• Coughing: A persistent cough that does not go away.
• Chest pressure: A feeling of heaviness or tightness inside the chest area.

Because these symptoms can be associated with many different health concerns, they require a careful evaluation by a clinician to find the right cause and determine if this procedure is appropriate for you.

Evidence overview

Pleurodesis is a well-established medical procedure supported by extensive clinical research. It is widely accepted as a standard treatment for patients experiencing recurrent pleural effusions (fluid buildup around the lungs) or recurrent pneumothorax (collapsed lung). Studies indicate that the procedure is generally effective at sealing the space between the lung and the chest wall to prevent fluid or air from returning.

Medical literature compares various agents used to create this seal. Talc is frequently identified in research as one of the most effective options, with high success rates for preventing fluid recurrence. Other agents, such as doxycycline or bleomycin, are also supported by evidence and may be chosen based on a patient's specific needs and medical history.

Safety notes and individualized care

While pleurodesis is considered safe for many people, it is not suitable for everyone. Your clinician will evaluate your lung function before recommending this procedure. For the procedure to work, the lung must be able to expand fully against the chest wall. If a patient has a "trapped lung" that cannot expand, or if there is an active infection in the pleural space, this treatment is typically not recommended.

Like all medical procedures, pleurodesis carries some risks. Your care team will monitor you closely for side effects, which may include:

• Pain and discomfort: This is a common reaction to the inflammation caused by the procedure. Pain management is a standard part of the care plan.
• Fever: Patients often experience a fever as the body responds to the medication introduced into the chest cavity.
• Infection or inflammation: While less common, there is a risk of infection or more serious lung inflammation.

Your healthcare providers will tailor the approach to your situation, ensuring that pain is managed and that the benefits of preventing future lung collapse or fluid buildup outweigh the potential risks.
