Summary
The recent increase in obesity has led to an increase in the need for bariatric surgery. In
this group of patients the postoperative pain management is of vital importance. One strategy
to improve postoperative analgesia is the use of intraoperative methadone, specially in those
patients which regional anesthesia is not feasible. There is evidence that the use of
intraoperative methadone can lead to a analgesia lasting 24 to 36 hours, while not associated
with increased side effects when compared to other opioids with short or intermediate
duration of action. In this study the investigators will evaluate the efficacy of
intraoperative methadone in reducing postoperative pain and opioid consumption.
