头位分娩评分法预测分娩方式的探讨

Study of cephalic presentation score in predicting the mode of labour

目的:探讨头位分娩评分法在单胎足月头位初产妇分娩方式预测中的应用。方法:回顾性分析2001年经试产758例单胎足月头位初产妇的临床资料,对采用头位分娩评分法预测的分娩方式与实际分娩的临床资料,对采用头位分娩评分法预测的分娩方式与实际分娩结局进行比较分析。结果:头位分娩评分总分≤9分的剖宫产阳性预测值达94.7%;总分≥12分的阴道分娩阳性预测值达91.8%;总的可预测率为81.3%。结论:头位分娩评分法能有效预测单胎足月头位初产妇的分娩方式,操作简便易掌握,值得产科临床常规应用。

Objective： To investigate the application of cephalic presentation score in predicting the mode of labour in nulliparous women with term singleton fetus with cephalic presentation.Methods： The clinical data in 758 cases of nulliparous women with term singleton fetus with cephalic presentation were studied retropecfively. The mode of labour predicted by cephalic presentation score compared with the actual delivery outcome.Results： The predictive coincidence rate（the positive predictive value） of cesarean section was 94.7% when cephalic presentation score ≤ 9.The positive predictive value of vaginal deliveny was 91.8% when total score ≥ 12.The total positive predictive rate was 81.3%. Conclusion： Cephalic presentation score can effectively predict the mode of labour in nulliparous women with term singleton fetus with cephalic presentation. It is easy and convenient and is worth routine application in clinical obstetrics.
