产程潜伏期延长62例临床分析

目的　探讨产程潜伏期延长的发病因素及处理。方法　收集了 1998年 1月至 1998年 7月间符合潜伏期延长诊断者 6 2例 ,同时收集了无潜伏期延长者 85例加以对照 ,对两组病例进行回顾性分析。结果　潜伏期延长组中胎儿体重≥ 35 0 0g者及胎头位置异常者分别占 40 35 %和 5 1 6 1% ,明显高于对照组 (分别为 2 1 81%和2 3 5 3% )。潜伏期延长组中难产发生率及羊水粪染率分别占 37 10 %和 43 5 5 % ,明显高于对照组 (分别为 12 94%和 2 3 5 3% )。结论　胎儿体重≥ 35 0 0g和胎头位置异常所致的头盆不称是引起潜伏期延长的主要因素。重视对潜伏期的观察及处理是预防潜伏期延长的关键 ,从而可减少难产的发生率。

The delay of labor course delitescence:clinical analysis of 62 cases

Objective To study the pathogenic factor and treatment of labor course delitescence delay.Methods\ 62 cases complied with delitescence delay were collected as study,at the same time,85 cases as control.Results\ The result showed that,fetal weights above 3500g and malposition of fetal head in the study group were respectively 40 32% and 51 61%.which was significantly higher than those in the control group(21 18% and 23 53%).The incidence of dystocia and the amniotic fluid meconium rate in the study group were respectively 37 10% and 43 55%,which was significantly higher than those in the control group(12 94% and 23 53%).Conclusion\ The major factors which resulted in delitescence delay were fetal weight above 3500g and head-pelvic asynergy resulted from malposition of getal head.The key point to prevent delitescence delay is to emphasize the monitoring and treatment of delitescence so as to reduce the incidence of dystocia.
