FHR monitoring and perinatal mortality in high-risk pregnancies.

The aim of the study was to evaluate the effect of the introduction of fetal heart rate monitoring on perinatal mortality rates in high-risk pregnancies. Results were compared with the perinatal mortality rates published previously from our clinics. The study group consisted of 2165 high-risk pregnant patients. The perinatal mortality rate in the study group was 28.6%, and the corrected rate 15.9%. The rates were significantly lower in comparison with the total perinatal mortality rates in former years. We are convinced that fetal heart-rate monitoring resulted in a significant decrease in the perinatal mortality rate. Although the increased use of fetal monitoring cannot reduce perinatal mortality resulting from problems such as genetic disorders, this study shows improved outcomes for many high-risk conditions, in particular postmature pregnancies.
