ABSTRACT
Introduction: the biophysical profile is one of the best methods of assessment of fetal well-being and prediction of adverse prenatal outcomes. Non stress test is a part of biophysical profile which had a high rate of false positive and decreased the score of biophysical profile that resulted to increase cesarean rate due to early intervention for termination of pregnancy
Objective: prenatal outcomes in high risk pregnancies with abnormal biophysical profile score without Non stress test
Materials and Methods: this c ross-sectional descriptive study was performed on 1000 women with high risk pregnancy who was admitted in Alzahra hospital for delivery. Information about variables were found according the contents of their files such as maternal age, gestational age, parity, cesarean rate, 1 and 5 minutes Apgar score <7, fetal heart abnormalities rate, meconium passage, low birth weight, fetal and neonatal death, and preterm labour. The score of biophysical profile 6-8 was considered normal and score <6 were considered abnormal. Data were analyzed by SPSS 11.5 and chi-square and Fisher Exact Test. P<0.05 was considered significant
Results: 1000 pregnant women with high risk pregnancy were evaluated in this study. 24.9% of them had biophysical profile score less than 6 which had considered abnormal. The comparison of the two groups showed that the rate of cesarean section, 1 and 5 min Apgar score < 7, fetal heart abnormalities rate, preterm delivery, and neonatal mortality rate were higher than in abnormal group [P<0.001]. But there weren't statistical significant differences between low birth weight, meconium passage, and fetal death in two groups
Conclusion: the biophysical profile without non stress test can be predicted poor prenatal outcomes in high risk pregnancies
