目的观察垂体后叶素联合子宫背带式缝合对中央型前置胎盘患者剖宫产术中及术后出血的影响。方法我院剖宫产分娩的中央前置胎盘产妇28例,随机分为两组,研究组16例,术中用子宫背带式缝合术基础上于胎盘娩出后立刻在剥离面散在、多点注射1∶1稀释后垂体后叶素6u;对照组12例,常规处理,包括按摩子宫,胎儿娩出后子宫肌注短效催产素20u。用容积法和称重法测量术中及术后24h出血总量。结果研究组平均手术时间50.58分钟,对照组平均手术时间67.53分钟,研究组产后平均出血量472.71ml,对照组产后平均出血量797.23ml,两组对比在手术时间、产后出血量方面差异有统计学意义,P<0.05。对照组有1例患者止血失败行子宫切除术。结论垂体后叶素注射联合子宫背带式缝合能缩短中央型前置胎盘剖宫产术的手术时间,减少术中及术后出血,安全可靠,疗效优于普通催产素注射。
Objective To observe the effect of pituitrin combined with uterus strap suture on cesarean section and postoperative bleeding in patients with central placenta previa. Methods 28 cases of cesarean delivery in the center of the placenta previa were randomly divided into two groups, the study group of 16 cases, intraoperative hysteresis suture based on the placenta immediately after delivery in the dissected surface scattered, multi-point injection 1: 1 diluted pituitrin 6u; control group of 12 cases, routine treatment, including massage the uterus, uterine intramuscular injection of short-acting oxytocin 20u. Volume and weight method were used to measure intraoperative and postoperative 24h total bleeding. Results The average operation time was 50.58 minutes in the study group and 67.53 minutes in the control group. The mean postpartum blood loss was 472.71ml in the study group and 797.23ml in the control group. There was statistically significant difference between the two groups in operation time and postpartum hemorrhage volume Significance, P <0.05. One patient in the control group had failed hemostasis for hysterectomy. Conclusions The combination of pituitrin injection and uterine strap suture can shorten the operation time of cesarean section in central placenta previa and reduce the intraoperative and postoperative bleeding, which is safe and reliable. The curative effect is superior to that of ordinary oxytocin injection.
