 The evidence reported for Carbetocin use in the literature has mostly been based upon low risk non-laboring patients undergoing elective cesarean deliveries. At present, only 2 studies have looked at the use of Carbetocin in low risk patients requiring emergency cesarean deliveries. The minimum effective dose ED90 of carbetocin in laboring women has not been determined so far. Similar to oxytocin, the ED90 of Carbetocin is likely to be higher in laboring women undergoing Cesarean deliveries as compared to the non-laboring women, due to the effect of the desensitization phenomenon.
