| 摘 要： | 目的通过对1 913例初产妇产程数据进行分析，探讨初产妇第一产程产程曲线特征。方法选取经阴道分娩的1 913例单胎、足月、头先露初产妇，其中自然临产产妇1 523例为自然临产组，应用静滴缩宫素计划分娩产妇390例为缩宫素组。采用回顾性分析方法，收集记录2组产妇的年龄、分娩孕周、体质量、身高、新生儿出生体质量、第一产程宫口扩张程度及持续时间，并计算宫口扩张每进展1 cm所经历的时间等资料。结果自然临产组分娩时孕周为（39.6 ±0.9）周，缩宫素组分娩时孕周为（39.9±1.1）周，2组产妇孕周差异有统计学意义（P < 0.05）。2组分娩时年龄、体质量、身高、体质量指数、新生儿体质量差异均无统计学意义（P>0.05）。2组产妇产程曲线均呈现缓慢上升趋势，在宫口开大5 cm后，2组产程的进展均呈现加速趋势。自然临产组宫口开大3~4、4~5、5~6、7~8 cm所持续的时间均长于缩宫素组（P < 0.05~P < 0.01），2组宫口开大6~7、8~9、9~10 cm所持续的时间差异均无统计学意义（P>0.05）。2组产妇活跃期起点分布差异无统计学意义（P>0.05）。结论Friedman产程图和新产程标准均不能很好描述国内人群产程特征，应进一步收集国内产妇产程数据，绘制合适的产程图指导产程处理。

| Abstract: | ObjectiveTo investigate the characteristics of carve of labour duration in the first labour stage by analyzing 1 913 cases of nulliparous women.MethodsA total of 1 913 cases of nulliparous women with singleton, full-term and cephalic presentation were selected and divided into natural parturient group (n=1 523) and oxytocin group (n=390).The age, birth gestational age, body mass, height, neonatal birth mass, dilatation and duration of uterine cervix, the time required for uterine cervix dilatation per 1 cm in two groups were collected and retrospectively analyzed.ResultsThe birth gestational age in natural parturient group and oxytocin group was (39.6±0.9) weeks and (39.9±1.1) weeks, respectively, the difference of which was statistically significant (P < 0.05).There was no significant difference in age, body mass, height, body mass index and neonatal birth mass between two groups (P>0.05).The carve of labour duration of nulliparous women showed a slowly rising trend in the first stage of labour, and the carve of labour duration presented ascending trend after the cervix opened 5 cm in two groups.The duration of uterine opening at 3-4, 4-5, 5-6 and 7-8 cm in natural parturient group was longer than that in oxytocin group (P < 0.05 to P < 0.01), and there was no significant difference in the duration of uterine opening at 6-7, 8-9 and 9-10 cm between two groups (P>0.05).There was no significant difference in the starting point distribution of active phase between two groups (P>0.05).ConclusionsBoth Friedman labour curve and the new obstetrics labor standard can not exactly describe the characteristics of labor in China.More maternal labor data in China should be further collected, and a suitable curve of labor duration should be drawn to guide the labor process. |
