Oxytocin 10 IU as Prophylactic for Uterine Atony : a Randomized Clinical Trial

Abstract

Objective : To compare the effectiveness of oxytocin dose of 10 IU and 20 IU for preventing uterine atony in women undergoing cesarean section. Methods : This was a double-blind, randomized clinical trial with good matching selection with randomization block of patients who had risk factors for the occurrence of uterine atony such as preeclampsia, patients were receiving MgSO4, oxytocin intrapartum and chorioamnionitis who performed stratified randomization prospectively with two kinds of oxytocin doses which are 10 IU and 20 IU as a prophylaxis for uterine atony in women who performed emergency cesarean section with transverse incision and were using a general anesthesia. Results : This study found no any significant differences between the use of 10 IU and 20 IU as prophylaxis for uterine atony during cesarean section either in its action at the time or while in recovery room, especially on the cases without chorioamnionitis thus using oxytocin 10 IU regimen can be considered, besides the effectiveness did no differ, it will cost cheaper than oxytocin 20 IU regimen which frequently used. Conclusions : There were no significant differences in the incidence of blood loss during the cesarean section between the treatment of oxytocin 10 IU group and oxytocin 20 IU group. The additional uterotonic was using during the action of the cesarean section between the treatment of oxytocin 10 IU group, and oxytocin 20 IU group gave no significant differences. The side effects in this study at least form of chills and vomiting found no significant differences between both of groups despite the side effects that arise in oxytocin 20 IU group was higher at 23.08% than oxytocin 10 IU group at 15.19%. Chorioamnionitis would be a risk factor for the occurrence of uterine atony during the action of the cesarean section if it associated with the use of additional uterotonic in oxytocin 10 IU group if compared with oxytocin 20 IU group.
