ABSTRACT
Objective To evaluate the value of admission test of fetal heart rate and artificial rup-ture of membrane in predicting fetal distress in labor. Methods 658 pregnant women who had been pregnant for 33+5 to 43 weeks and delivered spontaneously in 24 hours were divided into low risk group(598 cases) and hign risk group(60 cases) according to their admission test. The admission test, result of deliv-ery, amniotic fluid contamination and Apgar scores of newborns were analyzed. Results 515 cases were reactive type(78.27%), 72 cases were equivocal type(10.94%) and 71 cases were ominous type(10.79%). Total incidence of neonatal asphyxia were 6.53%,and it was 1.94% and 33.08% in reactive type subjects and ominous type subjects, respectively. The rates of anmiotic fluid contamination were 20. 97% and 67.61% in reactive type subjects and ominous type subjects (P<0.01). The incidence of reactive type and equivocal type of amniotic fluid contamination and neonatal asphyxia were significantly lower in the low risk group than those in the high-risk group (P<0.05). Conclusions Reactive type of admission test can ensure safety of fetus during the subsequent four to five hours. Admission test of fetal heart rate and artifi-cial rupture of membrane can be used to predict fetal outcome in labor.
