本文报道了对200例孕妇采用胎动计数方法了解胎儿状况。该法是以每例孕妇分娩前半月内每天胎动平均数与分娩前半月中平均基础数相比,计算波动进行胎动分型,共分四型。以Ⅱ型胎动,即每天平均次数减少大于50％、但可恢复的情况作为分界线时,各变异因素(围产儿情况、羊水性状及胎盘功能)的约登指数均为最高值。由此,可预测正常围产儿的96.90％,正常羊水的96.6％,正常胎盘功能的97.2％,其灵敏度均
This article reports the use of fetal movement counting method to understand the fetus status in 200 pregnant women. The law is based on the average number of fetal motions in each half of the first half of labor during each childbearing compared with the average basis of the first half of labor, the calculation of fluctuations in fetal movement type, divided into four types. With Type II fetal movement, ie, a decrease of more than 50% in the average number of days per day, the Youden index for each variation (perinatal, amniotic fluid, and placental function) was the highest at the time of recoverability. Thus, 96.90% of normal perinatal children, 96.6% of normal amniotic fluid, and 97.2% of normal placental function can be predicted, and their sensitivities are both
