Type of study
Randomized controlled trial
The study will be carried out at ward 23, Colombo South Teaching Hospital (CSTH).
Participants meeting the inclusion/exclusion criteria will be allocated to the study arms using computer generated random numbers.
Arm A (intervention arm) will receive a single rectal administration of diclofenac sodium 100mg (suppository) 30 minutes prior to the procedure. A single rectal administration of an identical matching placebo (suppository) will be given immediate post-operatively.
Arm B (control arm) will receive a single rectal administration of the placebo (suppository) 30 minutes prior to the procedure. A single rectal administration of diclofenac sodium 100mg (suppository) will be given immediate post-operatively.
Standard of care: All patients will be receive general anesthesia and will be given the standard weight calculated doses of same IV pain relief preparations during the surgery. If any of the subjects of either group develop pain they will be adequately provided with postoperative analgesia according to standard unit protocols (IV pethidine, IV / oral tramadol or diclofenac sodium suppositories).
Patients and outcome assessors will be blinded to the intervention status.
