BACKGROUND: This multicentre, double-blind, placebo-controlled study compared the opioid-sparing effectiveness and clinical safety of parecoxib sodium over 48 h, in 195 postoperative patients after routine total knee replacement surgery. METHODS:Elective total primary knee arthroplasty was performed under spinal anaesthesia, with a single dose of spinal bupivacaine 10-20 mg, and intraoperative sedation with midazolam 0.5-1.0 mg i.v., or propofol <6 mg kg(-1)h(-1). Patients were randomized to receive either parecoxib sodium 20 mg twice daily (bd) i.v. (n=65), parecoxib sodium 40 mg bd i.v. (n=67), or placebo (n=63) at the completion of surgery, and after 12, 24, and 36 h. Morphine (1-2 mg) was taken by patient-controlled analgesia or by bolus doses after 30 min. RESULTS: Patients receiving parecoxib sodium 20 mg bd and 40 mg bd consumed 15.6% and 27.8% less morphine at 24 h than patients takingplacebo (both P<0.05). Both doses of parecoxib sodium administered with morphine provided significantly greater pain relief than morphine alone from 6 h (P<0.05). A global evaluation of study medication demonstrated a greater level of satisfaction among patients takingparecoxib sodium than those taking placebo. Parecoxib sodium administered in combination with morphine was well tolerated. However, a reduction in opioid-type side-effects was not demonstrated in the parecoxib sodium groups. CONCLUSION:Parecoxib sodium provides opioid-sparing analgesic effects in postoperative patients.
