分析158例临产后胎心率异常的初产妇与有关因素的关系,并与无胎心异常的155例对照比较,结果:总产程、胎儿体重、高危孕妇、胎位异常和脐带异常均有非常显著差异(P<0.01)。胎心异常发生率为7.98％。提示,胎心异常伴羊水混浊占54.9％;Apgar≤7分占19.26％;难产率高于对照组一倍以上(P<0.001)等,故胎心率异常是分娩过程中的危险信号。并指出处理必须及时、果断。 Analysis of 158 cases of fetal heart rate after labor abnormalities of primipara and related factors, and with no fetal heart failure compared to 155 cases, the results: total labor, fetal weight, high-risk pregnant women, fetal abnormalities and umbilical cord abnormalities are very significant Difference (P <0.01). Abnormal fetal heart rate was 7.98%. The results showed that the fetal heart rate was 54.9% with amniotic fluid opacity, Apgar≤7 was 19.26%, and the rate of dysthymia was more than double that of the control group (P <0.001). Therefore, abnormal fetal heart rate was a dangerous signal during labor. And pointed out that the treatment must be timely and decisive.
