应用产程图对发现产程异常、指导产程处理具有重要意义。我们收集了180例产程曲线活跃期延长的病例与同期分娩的无延长病例对照,分析活跃期延长的原因,探讨活跃期异常与头位难产的关系。资料分析我院1985年初产妇头位足月分娩数4689例,本文选择了其中无明显头盆不称、胎儿出生体重2500g以上,产程图记载活跃期超过8小时的180例为延长组,并收集了同时期分娩的活跃期8小时以下的180例为无延长组作对照,然后对活跃期延长组中单纯延长与合并活跃期阻滞者再作比较。活跃期阻滞诊断标准为宫口扩张3cm 以上4小时无进展。1.胎儿体重以出生后体重为准,两组比较无显著差异,P>0.05。
The application of labor map to find abnormal birth process, to guide the production process is of great significance. We collected 180 cases of active prolongation of labor curve cases and prolonged delivery of non-prolonged cases of control, analysis of the reasons for the extension of the active period to explore the relationship between abnormal activity and head dystocia. Data analysis of our hospital in early 1985, the first delivery of 4689 cases of full-term births, this selection of which no obvious head basin is not known, the birth weight of more than 2500g, birth chart records active period of more than 8 hours for the extension group and collected In the same period of delivery, the active period of less than 8 hours was used as the control group, and then the prolongation of the active group was compared with the simple prolongation and active block. Active diagnostic criteria for the stagnation of the cervix 3cm more than 4 hours no progress. 1 fetal weight to birth weight prevail, no significant difference between the two groups, P> 0.05.
