Randomized Controlled Trial Comparative StudyUtilization of carbetocin for prevention of postpartum hemorrhage after cesarean section: a randomized clinical trial.
A randomized study involving pregnant women was conducted to compare the effectiveness of a single intravenous (IV) injection of carbetocin with that of a standard 2-h oxytocin IV infusion with respect to intraoperative blood loss in the prevention of uterine atony after cesarean section (CS). The two treatments also were compared for safety and ability to maintain adequate uterine tone and to reduce the incidence and severity of postpartum hemorrhage (PPH) in women at risk for this condition. ⋯ Carbetocin makes possible to obtain, with a single IV injection, results equivalent to those of oxytocin on the maintenance of uterine tonicity and the limitation of blood losses, in the peri- and in the post-operative period, during a delivery by CS. It has in addition a comparable tolerance. Even in our series adverse events are practically of the same type and similar frequency in both study groups. Thus, the effectiveness of carbetocin consists, thanks to its long half-life, on an unique injection, whereas oxytocin requires repeated injections or a perfusion of several hours, with a variability of the administered doses.
