B超监测在选择分娩方式中的临床指导意义

Clinical significance of ultrasound detection on choosing the delivery mode

目的探讨B超监测在瘢痕子宫分娩方式选择上的指导意义。方法对200例剖宫产术后再次妊娠病例进行B超检测,并根据妊娠晚期子宫下段瘢痕厚度分组,其中>3mm组147例,≤3mm组53例。结果所有产妇中成功阴道分娩者49例,占全部产妇的24.5%,其中瘢痕>3mm的产妇43例,瘢痕≤3mm的产妇6例。结论应用B超动态观察检测子宫下段瘢痕厚度及愈合情况,可以预测子宫下段先兆破裂,从而选择恰当分娩方式,预防子宫破裂发生,减少并发症发生。

Objective To study the clinical significance of ultrasound detection on choosing the delivery mode for scar uterus. Methods 200 cases of subsequent pregnancy after cesarean section were detected by ultrasound. And according to the scar thickness of the ioWer uterine segment in the late trimester of pregnancy,they were divided into 〉 3 mm group（147 cases） and 〈 3 mn ＇group （53cases）. Results There were 49 cases with successful vaginal delivery,which accounted for 24.5% of all the parturient women. And there were 43 cases in 〉 3 mm group and 6 cases in 3 mm group. Conclusion The application of dynamic ultrasound for observation and detection of the scar thickness and healing situation of the lower uterine segment can predict the threatened uterine rupture to choose appropriate delivery mode,prevent uterine rupture and reduce complications.
