Optimizing Outpatient Anesthesia (OSPREy-Outpatient Surgery Pain Relief Enhancement) (OSPREy)
January 31, 2024 updated by: Duke University
The overall goal of this research is to improve perioperative pain treatment, decrease post-operative opioid consumption, diminish opioid related side effects, and reduce postop opioid prescribing (and hence opportunity for diversion, abuse, addiction, and fatal overdose).

Detailed Description
This protocol will test the innovative, paradigm-shifting hypothesis that anesthesia for outpatient surgery with long-duration opioids (methadone), compared with conventional short-duration opioids, achieves better analgesia, with similar or diminished side effects, may reduce development of chronic postsurgical pain, improves recovery, and importantly, decreases postoperative opioid consumption and could hence diminish take-home opioid prescribing and shrink the population reservoir of unused opioids available for diversion and misuse.
Two cohorts will be studied, but analyzed separately. 1) Short-stay, anticipated next-day discharge surgery (compare short-duration vs long-duration opioid), 2) Same-day discharge surgery (compare short-duration vs long-duration opioid).
