Objective :To investigate the effects of oxytocin and Leonurus injection for prevention of postpar-tum hemorrhage and the effect of promoting uterine involution .Methods :304 cases randomly divided into control group and study group ,152 cases in each group .In the control group ,only the oxytocin was used and the study group used oxytocin combined with Leonurus injection .Comparison of two groups of contraction duration ,duration of lo-chia ,postpartum 2 h and 24 h when the amount of bleeding ,the incidence of postpartum hemorrhage ,uterine involu-tion (fundus height) and adverse drug reaction conditions .Results :The uterine contraction duration of study group was higher than the control group (P＜0 .05) ,the duration of lochia was lower than the control group (P＜0 .05) . The amount of bleeding after postpartum 2h and 24h in the study group was lower than that of the control group (P＜0 .05) .The incidence of postpartum hemorrhage in the study group was 0%,which was lower than that of the control group 3 .95%(P＜0 .05) .At the time of postpartum 3d and 5d ,the height of the uterus in the study group was lower than that of the control group (P＜0 .05) .The incidence of adverse reactions in the study group was 1 . 97%,which was lower than that of the control group 7 .24%(P＜0 .05) .Conclusion :Oxytocin and Leonurus injection on postpartum hemorrhage has significant preventive effect ,and further accelerate the involution of uterus speed .%目的:探讨缩宫素联合益母草注射液对产后出血的预防作用及促子宫复旧的效果.方法:选择进行分娩的产妇304例,按照随机数表法将其分为对照组与研究组各152例.对照组产时与产后仅应用缩宫素,研究组则应用缩宫素联合益母草注射液.比较两组宫缩持续时间、恶露持续时间、产后2 h与24 h的出血量、产后出血的发生率、子宫复旧情况(宫底高度)以及药物不良反应.结果:研究组宫缩持续时间高于对照组(P＜0 .05) ,恶露持续时间低于对照组(P＜0 .05).研究组产后2 h与24 h的出血量均低于对照组( P＜0 .05) .研究组产后出血的发生率0 .00%,低于对照组3 .95%(P＜0 .05).研究组产后第3天与第5天时宫底高度均低于对照组(P＜0 .05).研究组不良反应发生率为1 .97%,低于对照组7 .24%( P＜0 .05) .结论:缩宫素与益母草注射液对产后出血具有显著的预防作用,且进一步加快了子宫复旧速度.
