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.

Biophysical Profile

An assessment of amniotic fluid volume has become an important component of antenatal testing for the at-risk pregnancy. The presence of normal amniotic fluid volume, either in association with a reactive nonstress test or as a component of the biophysical profile is considered to reflect current fetal well being and probable absence of chronic stress. The chronically stressed fetus is likely to have low amniotic fluid volume because of the shunting of blood preferentially to the brain, heart and adrenal glands at the expense of other body systems during the period of chronic stress. Decreased renal blood flow leads to decreased urinary output. Because the primary component of amniotic fluid in the third trimester of pregnancy is fetal urine, ongoing chronic stress can be recognised as oligohydramnios.Precise amniotic fluid volume (AFV) measurement is accomplished either by use of a dye-dilution technique or by direct measurement of the fluid volume at the time of caesarean delivery. The need for laboratory support and the inherent invasiveness of dye-dilution procedures limits their application to study protocols. Direct measurement of AFV at caesarean delivery is reflective only of fluid volume at the time of delivery and cannot be used to serially evaluate fluid volume as a component of antenatal testing.

Background: The amniotic fluid is fundamental for proper fetal development and growth. Ultrasound visualization of the amniotic fluid permits both subjective and objective estimates of the amniotic fluid. Objective: The objective of this study was to determine the reference values of normal single deepest pocket (SDP) – upper and lower limits, mean SDP and variation of the SDP with gestational age among Igbo women of South-Eastern Nigeria extraction carrying uncomplicated singleton pregnancy. Methodology: This was a prospective cross sectional study involving 400 women carrying uncomplicated singleton pregnancies and who were sure of the date of the first day of their last menstrual period. The single deepest pocket / maximum vertical pool were determined once at presentation at the hospital.. The study was conducted from January 1st to December 31st 2015. The second author carried out all the scanning. The SDP was obtained. Results: The womens’ mean and median ages were the same at 28 years. The gestational age range of the pregnancies was 14-41 weeks. The mean SDP was 5.8cm, while the 5th and 95th percentiles were 3.3cm and 8.5cm respectively. There was no difference in the mean SDP in both term and preterm. There was irregular but continuous rise of mean SDP to a peak of 6.8cm at gestational age of 39 weeks. In conclusion, the participants had a mean SDP of 5.8cm. There was also a positive correlation between SDP and Gestational age. We therefore recommend a longitudinal study to assess perinatal outcome and abnormal amniotic fluid volume among Igbo women of South-Eastern Nigeria. Key words: Single Deepest Pocket, Uncomplicated Singleton Pregnancy, Igbo Women.
