目的探讨子宫动脉结扎在前置胎盘剖宫产术中的应用效果。方法选择2011年1月至2014年12月深圳市龙华新区人民医院收治的160例行前置胎盘剖宫产术患者作为研究对象,按照数字列表法随机分为观察组和对照组,每组80例,对照组患者未行子宫动脉结扎术,采用常规止血法,观察组患者行子宫动脉结扎术,比较两组患者输血量、术中出血量与产后出血率,及两组患者手术时间与子宫切除情况,比较两组新生儿情况。结果 1观察组患者的输血量与术中出血量均明显少于对照组,两组比较差异均有统计学意义(χ~2=12.671,9.657,P<0.05);观察组患者产后出血率为3.75%,显著低于对照组(51.25%),差异有统计学意义(χ~2=15.367,P<0.05);2观察组患者手术时间明显少于对照组,两组比较差异有统计学意义(t=8.529,P<0.05);观察组患者子宫切除率为0,显著低于对照组(6.25%),差异有统计学意义(χ~2=11.347,P<0.05);3与对照组新生儿相比,观察组新生儿脐动脉pH值、Apgar评分及新生儿体质量差异均未见统计学意义(P>0.05)。结论将子宫动脉结扎应用于前置胎盘剖宫术中,可明显减少术中出血量及手术时间,且能够显著降低产后出血与子宫切除的风险,安全可靠,值得临床推广。
Objective To investigate the effect of uterine artery ligation in cesarean section of placenta previa. Methods From January 2011 to December 2014, 160 patients underwent cesarean section with placenta previa in Longhua New District People’s Hospital of Shenzhen City were randomly divided into observation group and control group according to numerical list method Cases, the control group of patients without uterine artery ligation, the use of conventional hemostasis, the observation group patients underwent uterine artery ligation, blood transfusion volume, intraoperative blood loss and postpartum hemorrhage rate, and the two groups of patients with surgery and uterine time Excision, comparison of two groups of newborns. Results 1 The transfusion volume and intraoperative blood loss in the observation group were significantly less than those in the control group, with significant differences between the two groups (χ ~ 2 = 12.671, 9.657, P <0.05). The postpartum hemorrhage rate in the observation group was 3.75%, significantly lower than the control group (51.25%), the difference was statistically significant (χ ~ 2 = 15.367, P <0.05); 2 observation group was significantly less operation time than the control group, the difference between the two groups was statistically significant (t = 8.529, P <0.05). The hysterectomy rate in the observation group was 0, which was significantly lower than that in the control group (6.25%), the difference was statistically significant (χ ~ 2 = 11.347, Neonatal compared with the observation group neonatal umbilical artery pH value, Apgar score and neonatal body weight differences were not statistically significant (P> 0.05). Conclusions The application of uterine artery ligation in placenta previa can significantly reduce the amount of intraoperative bleeding and operation time, and can significantly reduce the risk of postpartum hemorrhage and hysterectomy, safe and reliable, worthy of clinical promotion.
