Fetal Heart Rate Monitoring Combined Fetal Umbilical Blood Flow Monitoring and Forecasting Study of Fetal Distress

Objective To monitor the fetal heart rate changes and fetal umbilical blood flow,and in order to find an accurate,early diagnosis and effective method of fetal distress.Methods All of 98 full-term pregnant women giving birth or because of medical indications require early termination of pregnancy,gestational age36 weeks pregnant were treated by electronic fetal heart rate monitoring from June 2009 to May 2010 in our hospital,and by ultrasound examination detected umbilical artery blood flow,and applied statistical methods to study the observed indicators and the relationship between the occurrence of fetal distress.Results In 98 cases selected for maternal,clinical diagnosis of fetal distress was 16 patients.Monitoring the two tests normal in 53 cases,false negative in 4 cases,the clinical rate was 92.45%(49/53).An abnormal in 24 cases,false positive in 7 cases,the clinical rate was 70.83%(17/24).Two abnormalities in 13 cases,false positive in 1 case,the clinical rate was 92.31%(12/13),with the single exception(single monitor) for the chi-square test,the difference was statistically significant(P0.01).Conclusion The monitoring of individual monitoring is to exclude the interference of various factors,to determine the fetal safety of the state to improve the accuracy.
