Modified biophysical profile in antepartum fetal surveillance of high risk pregnancies
Keywords:Amniotic fluid index, Amniotic fluid volume, Biophysical profile, Fetal heart rate, Modified biophysical profile, Non-stress test
Background: Fetal biophysical profile is a well-established method of antepartum surveillance in high risk pregnancy. Classical biophysical profile with all parameters (fetal breathing movements, fetal tone, fetal gross body movements, amniotic fluid volume and non-stress test) needs two phase testing by ultrasound and external Doppler monitor to record fetal heart rate, is more cumbersome, time consuming and expensive.
Methods: This study was a prospective clinical study which consisted of 70 patients having pregnancy with high risk factors. The patients were evaluated with the modified biophysical profile consisting of NST recording for 20mins, followed ultrasound assessment of amniotic fluid volume, using four quadrant technique.
Results: When the Modified biophysical profile is normal, it gives reassurance that the fetal status is good with good perinatal outcome. When the MBPP is abnormal there is increased incidence of perinatal morbidity as well as mortality.
Conclusions: Modified biophysical profile is an effective primary antepartum fetal surveillance test in high risk pregnancies in predicting perinatal outcome.
