Dressing for site of drain insertion
If a pneumothorax fails to resolve after 48 hours, refer to a respi-
ratory physician and consider adding high-volume/low-pressure
suction (e.g. 2.5-5 kPa). You may also consider inserting a bigger
drain. Discuss with the cardiothoracic surgeons if a pneumotho-
rax fails to resolve after 3-5 days.
If a drain stops swinging, it may be blocked, kinked or malposi-
tioned. A blocked drain may be unblocked with a fl ush of 10 mL
of sterile saline. A non-functioning drain should be removed.
Removal of intercostal drains
Following a pneumothorax, the chest drain can be removed when
the drain has stopped bubbling for 24 hours and a CXR confi rms
re-expansion of the lung.
Following a pleural effusion, the chest drain can be removed
when the CXR shows resolution of the effusion. Drain output will
usually be less than 100 mL per day.
To remove a chest drain, fi rstly cut the sutures which are holding
the drain in the skin. Ask the patient to hold their breath in expi-
ration or perform a Valsalva manoeuvre and remove the chest
drain. A suture will be required after removal of larger drains. A
mattress suture may have been previously placed for this purpose.
Apply a dressing and perform a CXR after drain removal.

Discharge and follow-up of patients with
Patients with a pneumothorax who are discharged without active
intervention should be advised to return in 2 weeks' time for a
follow-up CXR.
Patients should be advised to avoid air travel until 6 weeks
following resolution of the pneumothorax.
Scuba diving should be permanently avoided by patients who
have had a pneumothorax unless they undergo bilateral surgical
All patients should be given advice to return immediately should
they experience worsening breathlessness.
