初产妇头位分娩100例产程图分析

对５０例头位难产的初产妇（异常组）及５０例头位顺产的初产妇（对照组）的产程图进行分析。结果表明：异常组潜伏期、活跃期时限明显大于对照组（Ｐ＜０．００１），宫颈扩张速度和胎头下降速度都明显小于对照组（Ｐ＜０．００１）。异常组产后出血量、总产程、手术产率、新生儿窒息率都明显高于对照组（Ｐ＜０．００１）。异常组５０例中，经过积极处理后，有３８例阴道分娩，占７６％。提示：产程中应用产程图对发现产程异常、指导产程处理和识别难产具有非常重要的意义。

An investigation of abnormal partograpb inprimipara with vertex presentation

prospective study on partograph (cross X type)was carried out in primipara with vertex presentation.There were 50 cases of dystocia in the study group and50 cases of normal delivery in the control group. The re-sults showed that the latent phase and active period oflabor course in study group was significantly longer thanthe control group (P<0. 001 ). The speed of cervical di-lation and descent of fetal presentation in the studygroup was marked slower than the control group (P<0. 001 ). The rate of postpartum hemorrhage , total timeof labor, operative delivery rate and neonatal asphyxiarate in the study group were significantly higher thanthe control group (P < 0. 001 ). After active manage-ment 38 cases in the abnormal group were deliveriedvaginally. It suggested that the use of partography isvery important in revealing abnormal labor course anddetection of dystocia, guiding the management of labor.
