Run by Icahn School of Medicine at Mount Sinai · NCT07786012 · Data updated 2026-11-12
This study tests whether intrathecal buprenorphine provides better postcesarean pain relief than morphine for women undergoing a planned cesarean delivery.

Is this trial a fit for you?
✓Likely a good fit
Women undergoing singleton elective cesarean delivery at term gestation without allergies to buprenorphine or morphine and without chronic pain or prior opioid use.
✕Probably not a fit
Patients with neuraxial anesthesia that is not feasible or those with conditions affecting analgesic response or safety may derive no clear benefit.

What this trial studies
This randomized interventional study compares two intrathecal analgesics, buprenorphine and morphine, given during neuraxial anesthesia for elective cesarean deliveries. Eligible participants are women carrying a singleton pregnancy at term. The trial investigates which drug offers superior pain relief and potentially fewer side effects in the immediate postoperative period. Results could influence standard pain-management practices after cesarean sections. The study is led by Icahn School of Medicine at Mount Sinai and conducted at Mount Sinai Hospital in New York.
Why it matters
Potential benefit: If buprenorphine provides longer or more effective pain relief with acceptable safety, patients may experience less need for additional analgesics after cesarean delivery.
How similar studies have gone: Prior research in neuraxial analgesia has explored buprenorphine and morphine separately, showing potential benefits of each; the direct head-to-head comparison in cesarean patients is informative but not definitive.
