Methadone Versus Morphine for Orthopedic Surgery Patients

Phase 4 Completed 75 enrolled University of Louisville

RandomizedParallel-groupTriple-blindTreatment

Summary

The investigators propose to compare analgesia by methadone and ketamine with a combination of morphine and ketamine in orthopedic surgery patients with moderate to severe pain. The investigators hypothesize that when given with ketamine before surgical incision, methadone is more effective than morphine in reducing postoperative morphine consumption and reducing pain during movement.
