The relationship between the full biophysical profile and rapid biophysical profile in antepartum fetal surveillance

Objective: one of the best tests for the assessment of a fetus is the biophysical profile test which has a significant effect on fetus health and the outcome of pregnancy. The present study was designed to determine the relationship between the full biophysical profile and the rapid biophysical profile tests in antepartum fetal surveillance. Patients and Methods: In this prospective study, Singleton pregnancies (n=209) with more than 34 weeks of gestational age were chosen. Both full biophysical profile (FBP) and rapid biophysical profile (RBP) tests were performed for all the patients. The main outcome is Apgar score and NICU admission were analyzed by the SPSS. The sensitivity, specificity, positive predictive value, and negative predictive value of RBP were calculated. Results: Out of 209 people who entered the study, 48 women (23.0%) had gestational diabetes, 84 women (40.2%) had hypertension pregnancy (preeclampsia), 45 people (21.5%) had IUGR and 45 women (21.5%) had post-date pregnancy. For predicting adverse fetal outcomes of pregnancy, the sensitivity, specificity, positive predictive value, and negative predictive value of RBP were found as 95%, 73%, and 52%. 98%, respectively. Conclusions: According to the statistically significant positive correlation between RBP and FBP and its simple and rapid application, RBP might be an acceptable alternative method for primary antepartum fetal screening tests in overcrowded obstetrics centers.
