In general, a chest drain can be removed when:
- The patient’s clinical condition has improved
- The lung has fully re-expanded on chest imaging
- There is no air leak (bubbling in the drain) on Valsalva manoeuvre or cough
- There is minimal fluid drainage:
- Exact amount depends upon the indication
- Generally <100-150ml / day
- Any fluid drained is serous
- Should be removed with the patient either:
- Performing a Valsalva’s manoeuvre
- During expiration
- A brisk firm movement should be used
- An assistant should be present to tie the previously placed closure suture
- An X-ray should be performed and reviewed post-removal to assess for pneumothorax
