Abstract:
Objective To systematically review the effects of different delivery routes of oxytocin in preventing hemorrhage after cesarean section.Methods Databases including PubMed,Medline,Embase,Cochrane library,Wanfang Medical Database,China National Knowledge Internet (CNKI),VIP Database for Chinese Technical Periodicals were searched by computers and Conference papers were manually searched.The randomized,controlled clinical trials of oxytocin given by intramuscular injection,intravenous injection or intravenous infusion were included in elective cesarean section under spinal anesthesia.The quality of included literatures was evaluated by Cochrane systematic evaluation.The primary outcome measure was intraoperative amount of blood loss or change in Hb before and after operation.The secondary outcome measures were changes in blood pressure and heart rate,electrocardiogram,uterine contraction and other adverse reactions after using oxytocin.Results Seven studies involving 2 325 patients were included in this meta-analysis.Among the 2 325 patients,oxytocin was given through intramuscular injection in 79 cases,by intravenous injection in 1 147 cases and in the way of intravenous infusion in 1 099 cases.Compared with intramuscular injection group or intravenous infusion group,no significant change was found in the amount of blood loss during operation in intravenous injection group (P＞0.05).There was no statistically significant difference in the amount of blood loss during operation between intravenous injection group and intravenous infusion group (P＞0.05).Intravenously infusing oxytocin produced less effect on the mean arterial pressure and heart rate than intravenously injecting oxytocin (P＜0.01).Conclusion Intravenous infusion is a suitable route for oxytocin delivery in cesarean section with spinal anesthesia.
