Abstract
AIM: This study aimed to compare the hemodynamic profile and efficacy of carbetocin versus intra-umbilical oxytocin in the management of retained placenta following vaginal delivery. MATERIAL AND METHODS: In this randomized clinical study, women with retained placenta for more than 30 min were assigned to receive either an i.v. bolus of 100-µg carbetocin (n = 38) or an intra-umbilical vein injection of 50 IU oxytocin in 30 mL saline (n = 40). The main parameters evaluated were the success rate for expulsion of the placenta and the effects of these drugs on maternal blood pressure. RESULTS: The success rate in the carbetocin group was 86.84% compared to 77.5% in the intra-umbilical oxytocin group. Notably, 57.7% of the participants had prior induction of labor or augmentation during labor. There were no significant differences between the two groups regarding the estimated blood loss, drop of hemoglobin within the first 48 h, additional uterotonic injection or the need for manual removal of the placenta. Systolic blood pressure was significantly lower in the intra-umbilical oxytocin group at 30 and 60 min after injection (P = 0.008, 0.026, respectively). Nonetheless, diastolic blood pressure was significantly lower in the intra-umbilical oxytocin group than in the carbetocin group at 30 min (P = 0.036). CONCLUSION: A single i.v. bolus of carbetocin and umbilical vein injection of 50 IU oxytocin are similarly effective in reducing the need for manual removal of the placenta. Carbetocin seems to have an acceptable hemodynamic safety profile and can be used as an alternative choice to the conventional oxytocic agents in the management of retained placenta.
