Summary:This study was undertaken to assess the ability of each individual biophysical profile score variable and combination of variables, to predict fetal distress or imminent labor in the post data pregnancy. From June 1992 to August 1993, Biophysical Profile Scoring (BPS) was performed on 182 pregnant women. Thirty one patients delivered between 42 and 43 weeks of gestation, while the other 151 pregnant women delivered between 38 and 41+6 days. Monitoring procedures were based on the evaluation of fetal heart rates by Non Stress Test and four ultrasound parameters: Fetal Tone; Gross Body Movements; Fetal breathing movements; Evaluation of amniotic fluid volume. In this analysis the BPS showed a high specificity (82.7%) with a negative predictive value of 100%. The mean value of the last BPS among the 151 term patients was significantly higher if compared with the 31 post term pregnant women (6.73 and 6.12 respectively with p < 0.05). The predictive value of Fetal Breathing Movements (FBM) for the onset of imminent labor was confirmed. BPS, as measured in this study, has proved to be a very accurate method of determination of fetal well-being. Although these results will be further verified by other studies, BPS should come into general use to help reach the correct diagnosis and treatment of post date pregnancy.
