改良B-lynch缝合术治疗凶险性前置胎盘的效果观察

Efficacy observation on B-lynch suture operation in treatment of pernicious placenta previa

目的观察改良B-lynch缝合术治疗凶险性前置胎盘的临床效果。方法收集我科临床诊断为凶险性前置胎盘的患者46例,采用随机数字表法将其分为改良B-lynch缝合治疗组(改良组)与常规治疗组(常规组),每组23例;对2组患者的手术时间、月经恢复及血性恶露时间、产后出血、术中出血量、异常体温时间、胎盘植入、子宫切除及新生儿窒息情况进行比较。结果改良组患者术中及产后出血量少,月经恢复时间短,子宫切除率低,均优于常规组,差异具有统计学意义(P<0.05);2组患者在手术时间及血性恶露时间、胎盘植入、体温异常时间、新生儿窒息等方面的差异无统计学意义(P>0.05)。结论改良B-lynch缝合术治疗凶险性前置胎盘的临床效果显著。

Objective To observe the clinical effect of modified B-lynch suture in the treatment of patients with pernicious placenta pre-via.Methods A total of 46 patients with pernicious placenta previa in our hospital were randomly divided into the modified B-lynch suture treatment group（modified group）and the conventional therapy group（convention group）,with 23 cases in each group.The operation time, menstrual recovery time and lochia sanguinea time,postpartum hemorrhage,intraoperative blood soss,abnormal temperature time,placenta ac-creta,hysterectomy and neonatal asphyxia between the two groups were compared.Results The intraoperative blood soss and postpartum hemorrhage of modified group was less than those of convention group,the menstrual recovery time was shorter than that of convention group and the rate of resection of uterine was lower than that of conventional group,with significant difference （P 〈0.05）.There was no statistically significant difference in operation time,abnormal temperature time,lochia sanguinea time,placenta accreta and neonatal asphyxia between two groups （P 〉0.05）.Conclusion The clinical effect of modified B-lynch suture in the treatment of dangerous placenta previa is significant.
