A chest tube can help drain air, blood, or fluid from the pleural space, which is the space surrounding your lungs.

Inserting a chest tube is called a chest tube thoracostomy. It’s typically an emergency procedure, but it might also be done if you’ve had surgery done on the organs or tissues in your chest cavity.

During chest tube insertion, a hollow plastic tube is inserted between your ribs into the pleural space. This tube may be connected to a machine to help with the drainage. The tube will stay in place until the fluid, blood, or air is drained from your chest.

You may need a chest tube insertion if you have any of the following:

  • a collapsed lung
  • a lung infection like bacterial pneumonia complicated by collection of pus
  • pneumothorax, which is air around or outside the lung
  • bleeding around your lung, especially after a trauma (like a car accident)
  • fluid buildup due to another medical condition, like cancer or pneumonia
  • breathing difficulty due to a buildup of fluid or air
  • surgery, especially lung, heart, or esophageal surgery

Your doctor might also insert a chest tube if they need to diagnose certain conditions, like lung damage or internal injuries.

Since chest tube insertion is most commonly performed as an emergency procedure or after surgery, there’s usually no way for you to prepare for it.

If you’re conscious and your doctor thinks it’s necessary to insert a chest tube, they’ll ask for your consent. If you’re unconscious, they’ll explain why the chest tube was necessary after you wake up.

In cases where a chest tube insertion isn’t an emergency, your doctor will first order a chest X-ray so they can confirm whether you have a buildup of fluid or air causing your symptoms. Your doctor might also order some other tests to evaluate the pleural fluid, like a chest ultrasound or chest CT scan.

Usually, a chest tube procedure is performed by a surgeon or a pulmonary specialist, which is someone who specializes in lung conditions and diseases.

These are the steps involved in the procedure:


Your doctor will start by preparing a large area on the side of your chest, from your armpit down to your abdomen and across to your nipple. This will involve sterilizing the area and shaving any hair near the insertion site, if necessary.

Your doctor may also sometimes use an ultrasound to identify a good location for inserting the tube.


Your doctor may inject an anesthetic into your skin or vein to numb the area where they’ll be inserting the chest tube. This anesthetic medication will help make you more comfortable during the procedure because it can otherwise be painful.

If you’re having major heart or lung surgery, you’ll likely be given general anesthesia and be put to sleep before the chest tube is inserted.


Using a scalpel, your doctor will make a small (1/4- to 1 1/2-inch) incision between your ribs, near the upper part of your chest. The exact place they make this incision will depend on why you need a chest tube.


Your doctor will then gently open a space into your chest cavity and guide the tube into your chest. Chest tubes come in various sizes for different conditions.

Your doctor will stitch the chest tube in place to prevent it from moving during the procedure. A sterile bandage will be applied over the insertion site.


The tube is then attached to a special one-way drainage system that allows air or fluid to flow out only. This prevents the fluid or air from flowing back into the chest cavity.

While the chest tube is in, you’ll probably need to stay in the hospital. A doctor or nurse will monitor your breathing and check for possible air leaks.

How long the chest tube is left in depends on the condition that caused the buildup of air or fluid. Some lung cancers can cause fluid to accumulate, so your doctor may leave the tube in for a longer period of time in these cases.

Before a chest tube is inserted into the chest, the other end of the tube is put into a drainage system. This system consists of a bottle to collect the air or fluid and a leakage barrier water seal.

The leakage barrier water seal is created when the bottle is filled with a saline solution. Then one end of the tube is inserted into 2 cm of that saline solution, and the other is inserted into the pleural cavity.

This decompresses the pressure from the chest — or creates negative pressure — and removes the liquid or air because the pressure around the lungs is lower than the atmospheric pressure outside the body.

Chest tube insertion puts you at risk of several complications. These include:

  • Pain during placement. Chest tube insertion is usually very painful. Your doctor will help manage your pain by injecting an anesthetic through an IV or directly into the chest tube site. You’ll be given either general anesthesia, which puts you to sleep, or local anesthesia, which numbs the area.
  • Infection. As with any invasive procedure, there’s a risk of infection. The use of sterile tools during the procedure helps reduce this risk.
  • Bleeding. A very small amount of bleeding can occur if a blood vessel is damaged when the chest tube is inserted.
  • Poor tube placement. In some cases, the chest tube can be placed too far inside or not far enough inside the pleural space. The tube may fall out in this case. This is why you’ll be kept in the hospital to monitor.

Serious complications

Serious complications are rare, but they can include:

  • bleeding into the pleural space
  • injury to the lung, diaphragm, or stomach
  • collapsed lung during tube removal

Chest tube infection symptoms

One of the complications that can arise from a chest tube placement is an infection, or empyema. This occurs when bacteria enter the body around the tube and causes a lung infection.

The risk of infection increases the longer the chest tube is in your body, though your doctor can reduce your risk of infection if they bandage the skin around the tube insertion.

Signs of a lung infection from a chest tube insertion include:

What are the benefits vs. the risks of chest tube insertions?

Chest tube insertions come with risks, like empyema, organ rupture, malpositioning of the tube, and issues arising from the tube removal, like a collapsed lung.

But this is an emergency, life-saving procedure that can help treat collapsed lungs (pneumothorax). It can also remove excess fluid and air around the lungs, which makes it difficult to breathe.

When they’re needed, patients may be unlikely to recover without this intervention.

Was this helpful?

The chest tube usually stays in for a few days. After your doctor is sure that no more fluid or air needs to be drained, the chest tube will be removed.

The removal of the chest tube is usually performed quickly and without sedation. Your doctor will give you specific instructions on how to breathe when the tube is removed. In most cases, the chest tube will be removed as you’re holding your breath. This ensures extra air doesn’t get into your lungs.

After the doctor removes the chest tube, they’ll apply a bandage over the insertion site. You may have a small scar. Your doctor will likely schedule an X-ray at a later date to make sure that there isn’t another buildup of air or fluid inside your chest.

Sometimes, your doctor might prescribe antibiotics to prevent or treat an infection.

You won’t be discharged from the hospital until your incision site starts to heal. Before you leave, it can be helpful to ask your nurses to see what the incision looks like so you know how big it is and can notice any signs that it isn’t healing properly.

Don’t panic if there’s some light yellow or pink-colored drainage from the incision site — this can happen. If it does though, do write down the amount and color, and check if it smells. If it does smell, call your doctor and let them know.

If the drainage changes quickly or becomes substantial, you should also give your doctor a call.

You should keep your incision covered for at least 48 hours after the chest tube is removed, but you should wear it longer if you’re noticing discharge. If the bandage gets wet for any reason, change it quickly with a new dry one.

During your recovery, make sure to take care of yourself by:

  • getting some light exercise, even if it’s just a short walk outside, but see if you can do a little more each day
  • use your incentive spirometer, a device they’ll send home with you
  • do deep breathing and cough often to help re-expand your lungs
  • eat balanced meals regularly
  • drink lots of water
  • avoid alcohol and smoking, as both can interfere with your recovery
  • avoid anyone that’s sick in your household, as bacteria could cause you to get an infection
  • get plenty of rest at night, but try avoiding naps during the day
  • keep household activities light
  • take your any prescribed medication on a schedule
  • shower before sleeping

It usually takes about 3-4 weeks to recover from having a chest tube. Don’t drive until you’re able to fully use your arm and shoulder.

You’ll have a small scar from the procedure.

How effective are chest tubes?

Chest tubes can be effective at draining fluid and air from the pleural space. In many cases, it can help eliminate the need for a more invasive surgery.

Sometimes, though, it does not drain the space enough, and you may need surgery. Some people also develop a collapsed lung after removal of the tube, as well as bleeding in the pleural space, which might require more intensive treatment.

Are chest tubes painful?

When the procedure is performed, your doctor will likely use an anesthetic to numb your pain. But both the procedure and recovery can be painful.

One study found that 50 percent of patients experienced a pain level of 9 or 10 on a scale of 10.

You’ll be prescribed pain medications after the procedure to manage your pain post-procedure.

Can a chest tube cause nerve damage?

Yes, an incorrectly inserted chest tube can damage organs in your chest or m. Specifically, is can cause intercostal nerve impairment. This is one of the possible complications of this procedure.

Can a chest tube cause pneumonia?

Chest tubes can be used to remove pus from a pneumonia infection, and some patients may need re-intervention after the tube is removed because it doesn’t remove all the fluid.

But the tube itself doesn’t cause pneumonia.

Should my chest tube bubble?

It’s normal for there to be some intermittent air bubbling through the water seal chamber once your chest tube is inserted. This usually occurs when you cough or exhale.

But continuous air bubbling isn’t usual and could mean there is a leak in the tube.

A chest tube thoracostomy — or chest tube insertion — is an emergency, life-saving procedure that can be done when there’s air or fluid in your chest cavity, affecting your ability to breathe. It can also be performed if you have a collapsed lung.

This procedure, which involves putting a chest tube into your pleural space to remove the air or fluid, can lessen the chances that you’d need invasive surgery, but it’s not without risks. It’s possible to develop infections or have a buildup of fluid after the tube is removed.

Recovery from a chest tube insertion generally takes 3-4 weeks, but you can make a full recovery with just a small scar.
