The Clinical Research of the Oxytocin Intramuscular Injection at the Placenta Attachment Surface During Cesarean Section

Abstract：Objective:To evaluate the effect of the oxytocin intramuscular injection at the placenta attachment surface during cesarean section. Method:Randomly controlled clinical trial was adopted which contained 110 cases performed cesarean section.All the cases were injected oxytocin 10 U by intravenous route after the delivery of the baby.The observation group (55 cases) were performed oxytocin 10 U intramuscular injection at the placenta attachment surface,while the control group (55 cases) were injected oxytocin 10 U at the uterine wall but not at the placenta attachment site.The other procedures were the same as the observation group.The time from the baby delivery to the close of the uterine incision(T1),the blood loss during this period(V1),the time from the end up of oxytocin injection at the uterine wall to the placenta delivery(T2),and the postoperative blood loss within 24 hours(V2) were recorded.The data of the test was analyzed with the software SPSS 18.0.Result:The observation group VS the control group:the difference of T1 was no significant difference statistically(P>0.05), the difference of T2 was also no significant difference statistically(P>0.05),the difference of blood loss was statistically significant(P<0.05) both during operation and within postoperative 24 hours.The data of the observation group was better.Conclusion:At the cesarean section,with the basic intravenous injection oxytocin,the blood loss during operation and postoperative,and the extra hemostasis procedure were decreased by the way of intramuscular injection of oxyctocin at the placenta attachment surface.
