PANSAID Trial Summary: Hojgaard et al. randomized 556 patients who were scheduled to undergo total hip arthroplasty to pain control with a combination of paracetamol + ibuprofen or any one of them with placebo. The primary objective was to assess if post-op morphine requirement decreases with the use of adjunctive pain medications. The results showed significant decrease in morphine requirement when paracetamol and ibuprofen were used in combination full dose. Ibuprofen alone was also found to have signficant benefit in terms of decreasing the morphine requirement therefore, the authors concluded that isolated ibuprofen can be used as an adjunct pain medication to lessen the requirement of patient-controlled morphine in patients who undergo total hip arthroplasty.
