Study of drug control over postoperative hemorrhage after selective caesarean section

Objective: To compare the efficacy and safety of carbetocin and oxytocin in the prevention of postpartum hemorrhage after selective caesarean section. Methods: Two hundred and sixteen pregnant women who were going to deliver by caesarean section were randomly divided into two paralleled and controlled groups, of which the oxytocin group(group A) contained 105 women and the carbetocin group(group B) 111 women. 20 IU of oxytocin was administrated during operation for both groups, 10 IU directly into uterus and 10 IU intravenously. When the operation was over, 20 IU of oxytocin was dripped for group A lasting for 8 hours, while for group B 100μg of carbetocin was immediately injected intravenously for 1 minute. Blood loss as well as hemoglobin alteration was measured for the comparison of the effect of the two drugs. Blood biochemical indicators were introduced for the evaluation of the safety of carbetocin including the function of liver and kidney and the fasting glucose.Results: No significant difference was revealed between the two groups concerning the postpartum hemorrhage within 24 hours, the postpartum hemorrhage incidence and the changes of hemoglobin. There was no significant difference in the change of liver and kidney function, fasting glucose and electrolyte changes as well.Conclusions: Carbetocin has a similar effect and safety of oxytocin in controlling the blood loss of selective caesarean section.
