Effects of postoperative epidural analgesia with three different methods in cesarean section

Objective: To investiate effects of postoperative epidural analgesia with three different methods after cesarean section.Methods: One hundred and ninety-five patients undergoing cesarean section under combined epidural anesthesia were equally and randomly allocated in to A,B and C groups.Group A was performed 48 hours with pethidine.Group B was perfomed 48 hours with only one epidural infusion of 0.25% ropivacaine 5 ml+morphine 2 mg+droperidol 1 mg.Group C was perfomed 48 hours with a continuous epidural infusion of 0.25% ropivacaine 5 ml+morphine 2 mg+droperidol 1 mg,and was connected with a pump of analgesia,then perform patient-controlled epidural analgesia(PCEA).The analgesia efficacy were evaluated and visual analog scale(VAS) of 6,12,24,48 h were recorded.Result: The VAS score was significantly higher in group A than that in group B and group C.There were significant differences among three groups after 6,12,24,48 h.The VAS score was significantly higher in group B than that in group C.There was significant difference among three group after 24,48h.The duration by which the intestine resumed its motor function was greatly shorted in group C.Conclution: The continuous epidural analgesia can improve analgesic effect of PCEA with few of complications,even adapt it to patient with preoperative pain.
