What is Pleurodesis?
Pleurodesis deliberately causes the two layers of the pleura to stick together, eliminating the space where fluid or air can collect. A sclerosing agent (such as sterile talc) is introduced through a chest drain or during thoracoscopy.
Why it is done
- Recurrent malignant pleural effusion
- Recurrent pneumothorax in selected patients
Before the procedure
- Inform the team about blood thinners and allergies
- Blood tests (including clotting profile) may be checked
- An ultrasound of the chest will be performed to locate the fluid or air safely
- You can usually eat lightly unless sedation is planned
During the procedure
- The agent is instilled through the chest drain or sprayed during thoracoscopy
- Pain relief is given, as temporary chest discomfort and fever are common
After the procedure
- The drain stays in until drainage reduces
- Hospital stay of a few days is typical
Safety & risks
Common effects include chest pain and fever for a short period. Pleurodesis may not always succeed. Your doctor will discuss alternatives such as an indwelling pleural catheter where appropriate.
