Brief summary

Taurolidine-citrate solution has been used effectively as a catheter-lock device to reduce infection and blockage in central venous catheters and tunnelled peritoneal catheters and has been used intra-pleurally. This study aims to assess the safety of Taurolidine-citrate (TauroLock) in indwelling pleural catheters (IPCs).

Interventions

A syringe containing 5ml of TauroLock™ solution (Taurolidine 1%-citrate 4%) or placebo (0.9% sodium chloride) will be used as test drug/placebo in this study. Patients will be randomised to receive either test drug or placebo first. 2.5ml of solution will be instilled into the indwelling pleural catheter within 7 days of insertion (immediately following pleural drainage) and repeated 4 weeks later (with the taurolidine-citrate/placebo, whichever they did not receive). TauroLock/placebo will be i

TauroLock/placebo will be instilled twice to each patient ie. each patient will receive both TauroLock and placebo 4 weeks apart. This will be performed by clinical research fellow and documented in medication chart at the time of intervention.
