- W4213065774 abstract "Abstract Bacground: Intravenous oxycodone compared to morphine for postoperative pain relief is controversial. The purpose of this study was to assess opioid-related adverse events of oxycodone versus morphine in opioid-naive patients after orthopaedic surgery. Methods: Patients scheduled for total hip arthroplasty under general anesthesia combined with a multimodal analgesia (acetamnophen, nonsteroidal anti-inflammatory) were randomized in a triple-blinded trial to postopertaive pain treatment with either intravenous oxycodone or morphine (potency ratio 1:1). After surgery, patients received similar drug regimen for titration in the postoperative care unit (bolus 2-3 mg, 5 min period, when pain score was >3/10) followed by an intravenous patient controlled analgesia (bolus 1 mg, lockout time 7 min) postoperatively. The primary outcome was number of patients with ≥1 opioid-related adverse events within the first 24 hours (at least one of the following complications: nausea, vomiting, respiratory depression, pruritus, urinary retention requiring evacuation, allergy, hallucination). Secondary outcomes included pain scores, opioid consumption. Patients were followed up to 4 months. Results: The intention-to-treat analysis included 241 patients with similar characteristics. There were 55 patients with at least one opioid-related adverse events in oxycodone group versus 46 in morphine group (48% vs 40%, p=0.19; relative risk= 1.22 [0.91; 1.63]). Oxycodone versus morphine requirements were respectively: 6 [0-11] versus 8 [0-12] mg (p=0.06) for titration, 15 [8-26] versus 8 [5-16] mg (p=0.001) for PCA dose, and 22 [12-37] mg versus 19 [11-28] mg for the titration and PCA accumulated consumption (p=0.048). During the first 24 hours, there were no other differences in secondary outcomes between both drugs for (respectively oxycodone versus morphine in %): nausea (15 versus 13), vomiting (5 versus 5 ), urinary retention (20 versus 12 ) and pain scores. Conclusion: This study demonstrated that oxycodone required lower doses for titration in postoperative care unit, but did not significantly reduce opioid-related adverse events within the first 24 hours compared to morphine." @default.
