目的 探讨马来酸麦角新碱注射液在疤痕子宫孕产妇术后子宫复旧的有效性。方法 以60例具有剖宫产指征的疤痕子宫患者为研究对象。将患者随机分成观察组和对照组，产后分别给予马来酸麦角新碱和缩宫素治疗3 d。观察两组术后子宫大小变化、出血量、宫腔积液情况及恶露消失时间。结果 术后3、42 d观察组子宫大小三径之和分别为（29.9±2.0）cm、（15.8±±1.2）cm，显著低于对照组的（32.6±2.8）cm、（18.1±1.5）cm（P<0.05）；观察组术后24、48 h出血量、42 d宫腔积液发生率、产后恶露消失时间均显著少于对照组（P<0.05）。结论 马来酸麦角新碱可有效修复剖宫产后子宫，减少术后出血量、产后宫腔积液发生率及缩短恶露消失时间，提高子宫复旧效率。

Objective To evaluate the efficacy of Ergometrine Maleate Injection in accelerating postpartum uterine involution for women with scarred uterus. Methods The study included 60 cases of parturient women, who had indications for cesarean delivery, and with previously scarred uterus. The patients were randomized to receive either ergometrine in treatment group or oxytocin in control group, for 3 days following delivery. Uterine size after operation, amount of postoperative hemorrhage, incidence of hydrometra, and duration of lochia were compared between the two groups. Results The sum of uterine longitudinal, anteroposterior and transverse diameter on the 3rd and 42nd day were (29.9 ±2.0) cm and (15.8 ±1.2) cm respectively, less than those in control group (32.6 ±2.8) cm and (18.1 ±1.5) cm, P<0.05). Blood loss within 24 and 48 hours after operation, incidence of hydrometra on the 42nd day, and duration of lochia in treatment group were less than those in control group (P<0.05). Conclusion Ergometrine maleate significantly reduces volume of post-cesarean uterus, diminishes postpartum blood loss, decreases incidence of hydrometra, shortens duration of lochia, and thus hastens uterine involution.
