Chest drain insertion

Overview

A chest drain insertion is a procedure where a doctor places a thin, flexible tube into the space between your lung and chest wall. This tube helps remove air, fluid, or blood that has built up around the lung, allowing the lung to expand and breathe more easily.

Chest drain insertion is a common procedure in hospitals, especially in emergency departments and surgical wards.

It can affect anyone who has a condition causing air or fluid around the lung, such as a collapsed lung, pneumonia, chest injury, or after lung surgery.

Symptoms

Common symptoms

• Chest pain that gets worse when you breathe in
• Shortness of breath
• Feeling of pressure or tightness in the chest

Symptoms in children

• Rapid breathing
• Cyanosis (blue tint to lips or skin)
• Irritability or difficulty feeding

Symptoms in older adults

• Confusion or drowsiness
• Faster heart rate or low blood pressure
• Less obvious chest pain

Causes

Main causes

• Collapsed lung (pneumothorax) – air leaks into the space around the lung
• Pleural effusion – build-up of fluid, often from infection, heart failure, or cancer
• Chest injury that causes bleeding (haemothorax)
• After chest surgery to prevent fluid or air from re-accumulating

Risk factors

• Smoking or lung disease like COPD
• Recent chest surgery or trauma
• Infection such as pneumonia or tuberculosis
• Certain cancers that spread to the lung lining

When to see a doctor

See a doctor urgently if:

• If you have sudden sharp chest pain and trouble breathing
• If you have had a chest injury and symptoms develop

Book a routine appointment if:

• If you have ongoing chest discomfort or shortness of breath that does not go away

Diagnosis

Doctors usually find the problem first with a chest X-ray or CT scan. If air or fluid is seen, they may decide a chest drain insertion is needed to treat it.

Tests that may be done

• Chest X-ray
• CT scan of the chest
• Ultrasound to locate the fluid
• Blood tests to check for infection

What to expect at your appointment

You will be asked to change into a hospital gown and lie down or sit up. The doctor will clean the area and inject local anaesthetic to numb the skin. A small cut is made, and the tube is gently guided in. You may feel pressure but not sharp pain. The drain is stitched in place and covered with a dressing. You will have a chest X-ray after to confirm the drain is in the right position.

Treatment

Treatment with a chest drain involves removing the air or fluid so your lung can re-expand. The drain stays in until there is no more air or fluid coming out, which usually takes a few days. Medicines may be given to treat the underlying cause, such as antibiotics for infection or pain relievers for comfort.

Self-care at home

• Keep the drain site clean and dry – do not shower or bathe until the doctor says it is safe.
• Let your healthcare team know if you feel short of breath or have new pain.
• Do not pull on the tube or try to adjust it yourself.

Medical treatments

If the drain is for a large fluid collection, the fluid may be sent to the lab for testing. Sometimes medication is given through the drain to help prevent fluid from re-forming (pleurodesis). Pain relief is provided as needed.

When is surgery considered?

In rare cases, if the chest drain does not work or the underlying problem is severe, surgery (such as video-assisted thoracoscopic surgery) may be needed to repair the lung or remove the lining.

Living with this condition

While the chest drain is in place, you will stay in hospital. You can walk carefully with help. The drain may feel uncomfortable, but moving gently can help. Once the drain is removed, the small wound heals within a week or so.

Lifestyle tips

• Avoid heavy lifting or strenuous activities for a few weeks after the drain is removed.
• Do not go swimming or use a hot tub until the wound is fully healed.
• Follow your doctor's advice about returning to work or driving.

Diet and exercise

Eat a balanced diet to help healing. Gentle walking is encouraged once you are home. Stop any activity that causes pain or shortness of breath.

Mental health and emotional wellbeing

Having a chest drain can be frightening and may cause anxiety or stress. It is normal to feel worried about the procedure or recovery. Talk to your healthcare team about how you feel – they can offer support.

Prevention

Some causes of air or fluid around the lung, such as chest trauma, cannot always be prevented. But you can lower your risk of a collapsed lung by quitting smoking. Managing other health conditions like pneumonia or heart failure can help prevent fluid build-up.

Complications

If left untreated

• Worsening shortness of breath and low oxygen levels
• Infection in the chest cavity (empyema)
• Lung collapse that does not re-expand

Long-term outlook

With proper treatment, most people recover well and the lung re-expands fully. The underlying cause will need follow-up, but chest drains are a safe and effective way to help you breathe easier. Your healthcare team will guide you through recovery.
