摘要
难产可因产力或阻力异常所致,两者的处理不同,应予鉴别。本文报道对61例初产妇子宫收缩力测定对鉴别难产及预测分娩方式的价值。结果表明,经阴道分娩组所需的子宫收缩力明显低于剖宫产组,说明阻力越大,所需子宫收缩力越高,当超过一定限度时,仍不足以克服阻力,应及时行剖宫产术以免危害产妇及胎儿。根据本资料结果初步提出在产程进展的不同阶段的总子宫收缩力的警戒值及处理值作为鉴别难产、预测分娩方式及难产处理的指标。
Uterine activity was measured in 61 nulliparous at the first stage of labor, which was divided into three parts: part A, from the onset of labor to the cervix dilated at 3cm; part B, from 3 to 5cm; part C, from 5 to the cervix dilated completely(10cm). The total uterine impluse(TUI)was calculated in each part using both uterine activity integral(UAI)and Motevideo Unit(MU). The results showed that the value of TUI in any part was much more higher in the cesarean section group than the vaginal delivery group. According to the data, a warning value as well as a management value were suggested in the purpose of differentiating dystoeia and predicting the method of delivery.
