摘要
目的分析经会阴超声在过预产期产妇阴道分娩中的作用。方法选择70例行阴道试产的单胎头位初产妇,于宫口开大4 cm行第1次经会阴超声和内诊检查,并于检查后1~2 h行第2次检查,分析产程进展度数和胎头下降距离与内诊胎先露、分娩结局的关系。结果产程进展度数、胎头下降距离与胎头位置的线性关系为:Y产程进展度数=-6.532X+0.052(R^2=0.645,P<0.001),Y胎头下降距离=-2.354X+0.068(R^2=0.621,P<0.001)。当产程进展度数大于125°、胎头下降距离大于42 mm时阴道分娩可能大。结论经会阴超声具有预测分娩结局的作用,可用于监测过预产期产妇的阴道分娩。
Objective To explore the application of transperineal ultrasound in vaginal deliveries for women who delivered after expected date of childbirth.Methods Seventy primiparas with a single fetus in cephalic position were selected.The first transperineal ultrasound and internal examination were performed when the uterine cervix was 4 cm.The second examinations were performed 1-2 hours after the first examination.The relationships between the progression angle or progression distance and the position of prenatal presentation or delivery outcome were discussed.Results The results showed the following linear relationship between progression angle or progression distance and the position of prenatal presentation:Yprogression angle=-6.532X+0.052(R^2=0.645,P<0.001),Yprogression distance=-2.354X+0.068(R^2=0.621,P<0.001).The situation with an angle>125°and a distance>42 mm were related to the success of vaginal delivery.Conclusion Transperineal ultrasound could effectively predict the delivery outcome.It could be used for monitoring the progression of vaginal deliveries for women who delivered after expected date of childbirth.
