Background: Pregnancy is a unique, physiologically normal event in a women’s life. Objective of this study was to compare the efficacy of the doppler velocimetry versus non stress test in relation to perinatal outcome in high risk pregnancies.Methods: This is a prospective study conducted in the department of obstetrics and gynaecology, Narayana Medical College and Hospital. 100 women with high risk pregnancy were recruited. All were examined systematically, and Doppler velocimetry and non-stress test were done.Results: All cases were divided into four groups based on NST and doppler velocimetry of umbilical artery and middle cerebral artery. 10% of women had abnormal doppler. Middle cerebral artery doppler abnormality was noted in 3% and CPR abnormality in 3% of women in the study group. 15% had abnormal NST. In Group A, out of 88 patients 9 had fetal compromise. In Group B, out of 5 patients all had fetal compromise. In Group C, out of 4 patients none had fetal compromise. In Group D, all 3 patients had fetal compromise. In Group D, all 3 had neonatal deaths. Average birth weights in Group A was 2.7 kg, in Group B was 2 kg, in Group C was 2.5 kg, in Group D was 1.4 kg. Two (2.2%) newborn in Group A, 4 (80%) newborns in Group B, 3 (100%) in Group had Apgar < 7 at 5 minutes. 4 (4.5%) babies in Group A, 5 (100%) babies in Group B, 3 (100%) babies in Group D were admitted in NICU. Umbilical artery doppler was found to have sensitivity 46.6%, specificity - 94%, PPV - 93%, NPV - 54%. Middle cerebral artery doppler was found to have sensitivity 73.3%, specificity - 90%, PPV - 91.6%, NPV- 69.3%.Conclusions: In present study, highest percentage of perinatal complications and perinatal deaths were seen in groups with abnormal tests of NST and velocimetry. Group D had the worst perinatal outcome.

Fetal Surveillance

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.

Background: Aim and objective of current investigation was to evaluate perinatal outcome in high risk pregnancy with modified biophysical profile and also evaluate the efficacy of MBPP.Methods: Type of study was observational study, 100 patient fulfilling inclusion criteria were included in study. All women were subjected to modified biophysical profile comprises amniotic fluid index and non stress test. NST was performed with cardiotocogram, real time ultrasound scanning was performed. Perinatal outcome assessed in terms of admission to NICU, low birth weight, foetal distress, low APGAR score, neonatal mortality.Results: Out of 100 cases, 55 cases had reactive NST and 45 had non reactive NST. AFI was normal in 79 cases 21 cases had abnormal AFI. Diagnostic power was maximum seen with NST i.e. 76.36% (61.90% for AFI and 71.64% for combined MBPP) it indicates that NST is a good predictor to diagnose a compromised foetus.Conclusions: This study shows that pregnancy with high risk factors are associated with more chances of intrapartum complications perinatal morbidity and mortality , if MBPP was abnormal or any one parameter was abnormal, chances of perinatal morbidity were high.

Doppler Study

Background: Doppler ultrasound provides a non-invasive method of studying the status of various blood vessels. It provides a spectrum analysis of the velocities of moving red blood cells. Doppler sonography can provide useful information in a variety of gynecological and obstetric conditions. In obstetrics, Doppler velocimetry of the uteroplacental and fetoplacental circulation can be used to further investigate complications of pregnancy such as fetal growth restriction, other forms of fetal distress that result from fetal hypoxemia or asphyxia.Methods: In a prospective observational study, 93 pregnancies fitting in the criteria for high risk were evaluated by doppler velocimetry between 28-40 weeks of gestation. The flow velocity time wave forms were examined and quantitated by use of systolic/diastolic (S/D) ratio, resistance index (RI), pulsatility index (PI) values. The outcome of pregnancy was noted.Results: Fetuses with abnormal velocimetry are at higher risk with regard to birth weight, Apgar score, fetal distress, need of cesarean section, need of NICU admission. The patients with absent end-diastolic flow (AEDF)/reversal of end-diastolic flow (REDF) had poor perinatal outcome. Positive predictive value for small for gestational age (SGA) and fetal distress was 75% and 60% respectively. 23.8% babies needed to be kept in neonatal intensive care unit (NICU).Conclusions: Doppler velocimetry can be useful prenatal test for the patients of hypertensive disorder of pregnancy and IUGR. Abnormal doppler waveform changes indicate adverse perinatal outcome. Appropriate and timely interventions guided by doppler study help to reduce perinatal morbidity and mortality.

Fetal Compromise

Background: High risk pregnancies increase the maternal and fetal morbidity and mortality; and there is a need for appropriate investigation which can diagnose it early and predicts the morbidity and mortality. The objectives of this study were to compare the efficacy of Doppler velocimetry studies and NST in predicting fetal compromise in utero and compare their ability in predicting the perinatal outcome in cases of high risk pregnancies.Methods: It was a prospective cross-sectional hospital based study conducted at Central Referral Hospital (CRH) which is a teaching hospital of Sikkim Manipal Institute of Medical Sciences (SMIMS). The study was conducted over a period of eighteen months between November 2012 and April 2014. One hundred consecutive cases of high risk pregnancies were enrolled into the study and investigated with NST (non-stress test) and Doppler velocimetry and results were correlated with perinatal outcome. In all cases, accurate gestational age was established from detailed menstrual history and ultrasonographic evidence of gestational age. Detailed examination, history and investigation were undertaken in each patient. Inclusion criteria were patients with singleton pregnancy beyond 34 weeks having one or more high risk factors. In these patients antenatal surveillance was done by Doppler and NST and results of these tests were correlated with perinatal outcome. Based on the Doppler velocimetry and NST results, the study population was divided in to four groups. Pregnant women below 34 weeks, multiple pregnancy and women with no risk factors were excluded from the study.Results: Maximum (63%) patients belonged to pregnancy induced hypertension (PIH) group, followed by oligohydramnios (11%), and gestational diabetes mellitus (GDM). The study showed that patients with both NST and Doppler waveform abnormal (group D) had the highest percentage of neonatal complication, NICU admissions and perinatal deaths. Even those patients with NST normal but Doppler velocimetry abnormal (group B) had comparatively higher neonatal complications. However, in group with NST abnormal and Doppler velocimetry normal (group C) had no fetal compromise. It was observed that normal NST and normal Doppler velocimetry were not statistically different in predicting fetal compromise and prediction value was low. But abnormal Doppler had statistically significant (p value = 0.021) predictive value in detecting fetal compromise. In cases with abnormal Doppler and fetal compromise, NST was still normal showing that abnormal Doppler waveform was better in predicting the bad perinatal outcome. Three out of 100 cases had absent end diastolic flow (AEDF) and all 3 were associated with perinatal morbidity with 2 perinatal deaths. Cerebroplacental ratio was < 1.08 in seven cases and all seven had neonatal complications including 3 neonatal deaths which also had AEDF. Thus, cerebroplacental ratio was better in detecting fetal compromise as compared to NST.Conclusions: Doppler velocimetry was better in predicting fetal compromise in comparison to NST in high risk pregnancies. Normal NST and normal Doppler velocimetry were not significantly different in prediction of fetal outcome. Abnormal Doppler value was better in predicting fetal compromise in comparison to abnormal NST.
