摘 要 目的:探讨麦角新碱联合卡贝缩宫素对前置胎盘剖宫产产后出血的影响。方法:选择2017年5月—2019年4月江西省妇幼保健院产科收治的前置胎盘剖宫产产后出血产妇96例,依据随机对照原则分为两组,每组48例。对照组患者采取20 U卡贝缩宫素静脉推注联合宫腔填塞纱布治疗,观察组则在对照组基础上子宫肌肉注射0.2 mg麦角新碱。观察患者生命体征变化情况、宫缩持续时间、宫底下降速度、恶露持续时间以及出血情况。结果:两组血氧饱和度、收缩压、舒张压均较稳定,和干预前相比差异无统计学意义(P>0.05)。干预后,观察组宫缩持续时间短于对照组,宫底下降速度快于对照组,恶露持续时间短于对照组(均P<0.05);观察组2 h出血量少于对照组(P<0.05),止血时间短于对照组(P<0.05)。观察组治疗总有效率为97.92%,高于对照组的87.50%(P<0.05)。结论:麦角新碱联合卡贝缩宫素对前置胎盘剖宫产产后出血有良好的治疗作用,对患者生命体征无明显影响,可以加快宮底下降速度,缩短恶露持续时间,减少出血时间并降低出血量,应用价值较高。

ABSTRACT Objective: To investigate the effect of ergonoxine combined with carbetocin on postpartum hemorrhage of placenta previa after cesarean section. Methods: Ninety-six cases of postpartum hemorrhage of placenta previa after cesarean section admitted to the Obstetrics Department of Jiangxi Provincial Maternity and Child Health Hospital from May 2017 to April 2019 were selected, and according to the randomized control principle divided into two groups with 48 cases in each group. The patients in the control group were treated with 20 U carbetocin intravenous injection combined with intrauterine packing gauze, and on the basis of the control group, the observation group was given 0.2 mg ergonoxine intramuscular injection. The changes of vital signs, duration of uterine contraction, descending speed of uterine fundus, duration of lochia and bleeding were observed. Results: The oxygen saturation, systolic blood pressure and diastolic blood pressure of the two groups were stable, and compared with the pre-intervention, the difference was not statistically significant(P>0.05). After the intervention, the duration of contractions in the observation group was shorter than that in the control group, the rate of uterine fundus decline in the observation group was faster than that in the control group, and the duration of lochia in the observation group was shorter than that in the control group(P<0.05); the amount of bleeding in 2 hours in the observation group was less than that in the control group(P<0.05), and the hemostasis time in the observation group was shorter than that in the control group(P<0.05). The total effective rate in the observation group was 97.92%, which was higher than 87.50% in the control group(P<0.05). Conclusion: Ergonoxine combined with carbetoxine has a good therapeutic effect on postpartum hemorrhage of placenta previa after cesarean section, and has no significant effect on vital signs of patients, which can accelerate the rate of descent of the uterine fundus,shorten the duration of lochia, reduce the bleeding time and the amount of bleeding, and has high application value.

产后出血是产妇在分娩过程中常见的并发症之一,不及时救治死亡率高,对产妇的生命安全造成直接危害[1]。美国妇产科医师学会(ACOG)2017年发布的产后出血临床实践简报中明确定义产后出血是指产后24 h内失血≥1 000 mL或伴有低血容量症状及体征的情况[2]。前置胎盘产妇需通过剖宫产终止妊娠,发生大出血的风险相对增加[3]。麦角新碱、卡贝缩宫素等是全新的催产素受体激动剂,能够快速起效,预防子宫收缩乏力等[4]。本院开展了麦角新碱联合卡贝缩宫素对前置胎盘剖宫产产后出血的影响研究。汇报如下:
