title: Prevention of post operative pain after abdominal hysterectomy by single dose etoricoxib.
abstract: OBJECTIVE
  To test whether a reduction in post operative morphine consumption could be achieved by a single-dose of etoricoxib before induction of anesthesia.
  
  
  METHODS
  Randomized, double-blind, placebo-controlled study.
  
  
  METHODS
  Two hours before surgery, patients undergoing transabdominal hysterectomy (under general anesthesia) were randomized to a single oral dose of 1) etoricoxib 120 mg (n = 17), 2) etoricoxib 180 mg (n = 17), or 3) placebo (n = 15). Intravenous morphine was given for patient-controlled analgesia (PCA) device. Morphine consumption, pain scores both at rest and on coughing, and side-effects were recorded at 1, 2, 4, 8 and 24 h after surgery. Patients' global evaluation of study medication was assessed at the end of the present study.
  
  
  RESULTS
  Etoricoxib provided greater clinical benefit than the placebo in terms of mean morphine in milligram at 24 hour consumption (stardard deviation): a) 26.4 mg (SD of 11.2) for etoricoxib 120 mg; b) 27.2 mg (SD of 9.9) for etoricoxib 180 mg; and, c) 36.6 mg (SD of 8.9) for the placebo group. At 8 h post surgery, pain both at rest and on coughing in the active drug groups was significantly less than in the placebo, while pain on coughing was significantly less at 24 h. Patients reported better global satisfaction and less somnolence in the etoricoxib groups.
  
  
  CONCLUSIONS
  Single dose etoricoxib 180 mg given before surgery provides the same analgesic effect as 120 mg for post operative pain after an abdominal hysterectomy.
