A Prospective Comparison of Methadone, Fentanyl, and Morphine for Post-laparotomy Epidural Analgesia

March 20, 2022 updated by: Hadassah Medical Organization

A Prospective Double Blind Randomized Comparison of Methadone, Fentanyl, and Morphine for Post-laparotomy Epidural Analgesia.

The current study aim is to compare between the opioids morphine, fentanyl and methadone in terms of efficacy and side effects profile when administered epidurally for pain management after laparotomies. Intravenous morphine will also be used. The outcomes of that method will be compared to those obtained using epidurally administered opioids, as this is another commonly used postoperative pain relief method.
