Objective To compare the application value of umbilical artery，electronic fetal monitoring and fetal biophysical behaviors and to explore the predictors of adverse neonatal outcomes in the patients with preeclampsia. Methods A total of 123 singleton pregnant women with preeclampsia who underwent umbilical artery electronic fetal monitoring，ultrasonographic biophysical profile，biophysical profile，modified biophysical profile（MBPP）were selected. The results of the five kinds of monitor methods within one week before delivery and neonatal outcomes were recorded. The data of every monitor methods were grouped and compared，to find out the predictive factors of adverse neonatal outcomes. Results The incidence of adverse neonatal outcomes was higher in the group with absent or reversed end diastolic velocity of the umbilical artery（UA-AREDV）compared with the normal umbilical artery group（P＜0.01）；the incidence of adverse neonatal outcomes was higher in the group with abnormal NST （or type III figure）compared with the normal electronic fetal monitoring group （P＜0.01）；the incidence of adverse neonatal outcomes was higher in the group with abnormal MBPP scores compared with the normal scores group（P＜0.05）.The diagnostic odds ratios of UA-AREDV and abnormal NST （or type III figure） were 18.4 and 5.9 respectively in predicting adverse neonatal outcomes of patients with preeclampsia. The positive predictive value and negative predictive value of UA-AREDV were 82.1% and 81% and the positive predictive value and negative predictive value of abnormal NST （or type III figure） were 72.2% and 73.3% in the diagnosis of adverse neonatal outcomes. Conclusion There are many indexes of fetal intrauterine monitor in the pregnant women with preeclampsia. umbilical artery，electronic fetal monitoring and MBPP are profit.UA-AREDV and abnormal NST （or type III figure） are valuable in predicting neonatal adverse outcomes.
