ABSTRACT

Objectives: To know the validity of modified biophysical profile in predicting fetal outcome before and after 40 weeks of gestation. Materials and methods: A prospective comparative study was done at Al-Ameen Medical College and Hospital, Vijayapur including 200 low risk patients, in which 100 patients are <40 weeks and 100 patients >40 weeks of gestation. Modified biophysical profile was done that is NST (for 20 mins) and AFI (by ultrasonography). Perinatal outcome was followed up with the help of Apgar score, birth weight, NICU admission, mode of delivery. Result: NST was nonreactive in 29% in >40 weeks group as opposed to 16% in <40 weeks group and oligohydramnios was in 12% in >40 weeks group as compared to the 3% incidence in <40 weeks group. LSCS rate was 49% in >40 weeks group compared to 38% in <40 weeks group. Apgar score and NICU admissions were not much different because of early detection of fetal distress and early intervention. Conclusion: Postdated pregnancies have more perinatal morbidity and mortality. MBPP is a good method to perform fetal surveillance in low risk pregnancies, So that unnecessary fetal compromise can be prevented therewith and better fetal outcome can be achieved.
