Perhaps you have felt a little tight or uncomfortable in your throat when you woke up after surgery. Or you may have seen someone close to you in the intensive care unit (ICU) with a tube in their mouth. Today we are talking about removing the tube that helps them breathe. This is called extubation in medical terms. Although this may sound like a scary word, it is actually a very good sign on your recovery journey.
First, let's see, what are Intubation and Extubation?
This is very simple.
- Intubation: Imagine that you are unable to breathe on your own due to an illness, an accident, or major surgery. At that time, doctors will insert a flexible tube through your mouth into your windpipe. This tube is called an Endotracheal Tube (ETT) . This tube is connected to a ventilator and provides oxygen to your lungs. Intubation is the process of inserting this tube.
- Extubation: When your health has improved and the doctors are confident that you can breathe well again on your own, without any help, they will carefully remove the previously inserted tube (ETT). This is the process we call extubation .
Why does someone need to be intubated like this?
There are several reasons why someone may not be able to breathe on their own. These are some of the main reasons why intubation may be necessary before extubation.
| Reason | A simple explanation |
|---|---|
| Surgery | General anesthesia, which is given during major surgeries, temporarily stops our breathing process. Therefore, this tube is inserted to help us breathe during the surgery. |
| Respiratory Failure | Severe infections like pneumonia and damage to the lungs can prevent the body from getting the oxygen it needs. |
| Airway Obstruction | This is necessary to keep the airway open in cases where something is stuck in the throat or the airways are swollen due to a severe allergy. |
| Trauma | Severe injuries to the head , neck, and chest can damage the respiratory system. |
| Loss of Consciousness | When someone loses consciousness, they may not be able to control their airway. There is also a risk of things like vomit getting into the lungs (aspiration). |
How is extubation performed? What is the process?
This is not just a matter of removing a tube and putting it back in. The medical team does this with great planning and care.
How do doctors decide when it's time to remove the tube?
They do a special test for this. It's called the Spontaneous Breathing Test (SBT) . Simply put, this tests whether you can breathe on your own with very little help from the ventilator. It's like taking a little 'test drive' when you're learning to drive a car. If you pass this test, it means your lungs are strong enough to work again.
They will also check your ability to cough and clear your throat (gag reflex). This is important to ensure that you can keep things like food and drink out of your lungs.
Steps to remove the tube
After you pass the SBT, the doctor or trained nursing staff will follow these steps:
1. Bed preparation: You will be brought into an upright position in bed.
2. Cleaning: A special suction device is used to remove all the mucus and debris from your mouth, throat, and inside the tube.
3. Removing the tape: The plaster or tape that holds the tube to the face is removed.
4. Giving breathing instructions: The doctor tells you to "take a deep breath and cough." As you cough, they remove the tube in a quick, smooth motion.
This entire process takes a few seconds. You may not even feel it.
What happens after extubation? What to expect?
The first thing you'll feel after the tube is removed is a huge relief! However, you may also experience some soreness in your throat and hoarseness for a few days. This is completely normal. It's like a sore throat from screaming for a long time.
After the tube is removed, the medical team will continue to monitor you.
- Your blood oxygen levels are checked regularly.
- Pay attention to your heart rate and breathing pattern.
- Sometimes, as a small help at first, a little oxygen can be given through a nasal cannula or an oxygen mask.
Are you conscious when you remove the tube?
This depends on the reason you were put on the tube.
- For surgery: Often, the tube is removed right after the surgery, before you fully wake up from the anesthesia. When you wake up, the tube is gone.
- In the Intensive Care Unit (ICU): If you are being treated for an illness or accident, the tube will be removed while you are conscious. But don't worry, the medical team will explain everything to you and make you feel calm.
Are there risks and complications of extubation?
As with any medical procedure, there are some very small risks involved. But these don't happen very often. Doctors are well aware of this, so they are always prepared to deal with such situations.
The main complication is extubation failure . This means that after the tube is removed, you are unable to breathe properly again and have to be re-intubated.
- This only happens to a small percentage of people, about 10%-14%, who have their tubes removed on a planned basis.
- This risk is slightly higher for people over 65 years of age, and those with heart disease or chronic lung disease.
Other minor complications:
- Voice changes and sore throat: This is a common condition that many people experience and will improve on their own within a few days.
- Stridor: Sometimes, a slight whistling sound can be heard when breathing due to swelling in the throat. Doctors know how to treat this.
- Severe coughing: The coughing that occurs when the tube is removed can sometimes cause a tightening of the throat muscles (laryngospasm).
The important thing is that all of these things happen very rarely. Your doctor is prepared for all of these things. So don't worry unnecessarily about this.
Take-Home Message
