  • Title: Fetal surveillance in insulin-dependent diabetic pregnancy: predictive value of the biophysical profile.
    Author: Dicker D, Feldberg D, Yeshaya A, Peleg D, Karp M, Goldman JA.
    Journal: Am J Obstet Gynecol; 1988 Oct; 159(4):800-4. PubMed ID: 3052075.
    Abstract:
    Ninety-eight insulin-dependent diabetic pregnancies underwent monitoring by means of 978 biophysical profiles from 28 weeks' gestation until parturition. Only 2.9% of the 978 tests had abnormal results (score less than or equal to 7). When performed within 2 days before birth, a normal biophysical profile predicted the 1-minute Apgar score to be normal in 92% and 5-minute Apgar score in 99%. When all biophysical profiles ever performed were included, the predictive value improved to 100%. The baby's first cry within 1 minute after birth was predicted in 95%. Furthermore, the predictive value of a normal biophysical profile regarding the absence of ominous intrapartum cardiotocographic patterns was excellent (95%). The specificity was in general good (80% to 90%), but the predictive value of abnormal test results and sensitivity were almost without exception poor. It seems that the very low rate of abnormal biophysical profiles indicates that obstetric interventions were made immediately after the occurrence of the first sign of fetal jeopardy; thus improved results were obtained.
