Carbetocin at Elective Cesarean Delivery Part 2
Carbetocin at Elective Cesarean Delivery: A Dose Finding Study (Part 2)
研究概览
详细说明
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.
