本文分析29例具有峰状曲线的产程图,与29例无峰状曲线配对组产程图。以多因素分析方法,发现影响峰状曲线出现的主要因素为宫颈水肿、活跃期时间、胎方位等。建立了预测是否会出现峰状曲线的判别函数,其对研究组及新病例的回代符合率分别为94.83％和86.05％。本研究应用于临床,可预测并防止峰状曲线的出现,及时转化早期产程梗阻。 In this study, 29 cases with peak-like curve were analyzed, and 29 cases with no peak-like curve were produced. Using multivariate analysis methods, it was found that the main factors affecting the appearance of peak-like curves were cervical edema, active period, and fetal orientation. A discriminant function was established to predict whether there would be a peak-like curve. The coincidence rates for the study group and the new case were 94.83% and 86.05%, respectively. This study is applied to clinics to predict and prevent the appearance of peak-like curves and timely transform early stage obstruction.
