Carbetocin at Elective Cesarean Delivery Part 2

Status Completed

Clinical Trial Summary

Post-partum hemorrhage (PPH) is a major cause of maternal death worldwide. Oxytocin is the most common uterotonic drug used to prevent and treat PPH in North America, however, there are some limitations to its use. Oxytocin has a very short duration of action, which requires a continuous infusion to achieve sustained uterotonic activity. The Society of Obstetricians and Gynecologists of Canada (SOGC) has recently recommended a single 100mcg dose of carbetocin at elective Cesarean delivery to promote uterine contraction and prevent post partum hemorrhage (PPH), in lieu of the more traditional oxytocin regimens. Carbetocin lasts 4 to 7 times longer than oxytocin, with a similar side effect profile and apparent greater efficacy rate. However, a dose response to determine the minimum effective dose of carbetocin has not yet been published. The investigators hypothesize that the minimum effective dose (ED90) is above 20mcgs and below 80mcgs in women undergoing elective Cesarean delivery.

Clinical Trial Description

The Society of Obstetricians and Gynecologists of Canada (SOGC) recently recommended a 100mcg intravenous bolus dose of carbetocin following Cesarean delivery.

Studies thus far show that carbetocin may be just as effective as oxytocin in promoting uterine contraction, with a similar side effect profile. In addition, patients receiving carbetocin may experience less blood loss, and require less additional uterotonics when compared with oxytocin. A dose response study conducted by Cordovani et al suggested no difference in efficacy of uterine contraction for doses of carbetocin between 80-120mcg. Additionally, hypotension was noted for all dose groups studied.

The results of this follow-up study will define the minimum required dose of carbetocin for uterine contraction, thus minimizing unnecessary side effects, improving quality and safety of patient care. It may also contribute in establishing carbetocin as a substitute to oxytocin for elective cesarean section at our institution as well as others. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
