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.

Prospective Case Control Study

Background: Placenta plays a very important role in the growth and development of fetus. Objective: To know the correlation between placental weight and perinatal outcome in term antenatal women. Methods: Present prospective case-control study was conducted in the rural tertiary center of Northern India over one year (January-December 2018) on 1,118 term (≥37-≤42 weeks) antenatal women with singleton pregnancy fulfilling inclusion criteria with 559 women with high-risk pregnancy as cases and 559 low-risk pregnant women as controls. Placental weight, birth weight was measured immediately after delivery and compared between the two groups along with gestation, parity, fetal gender, and neonatal outcome. Statistical analysis was done using SPSS 22 version. Results: Mean placental weight [481.98±67.83 gm vs. 499.47±59.59 gm (p=.000)] and birth weight [2.68±0.53 Kg vs. 2.88±0.4 Kg (p=.000)] was significantly lower in high risk as compared to lowrisk participants, whereas placental birth weight ratio was higher in high-risk cases [18.35±2.37 vs. 17.41±1.38 (p=.000)] respectively. Placental weight was positively correlated with birth weight and placental weight and birth weight increased with increasing gestation in both cases and controls. Male neonates had higher placental weight [492.74±68.24 gm vs. 488±58.8 gm (p=0.224)] and birth weight [2.81±0.5 Kg vs. 2.74±0.45 Kg (p=0.033)] as compared to females. Neonatal Intensive Care Unit admission was significantly associated with low placental and birth weight (p=.000). Conclusion: There is a significant correlation between placental weight, birth weight and neonatal outcome, hence placental weight can be used as an indirect indicator of intrauterine fetal growth.

A Prospective Study

This was a prospective study conducted in pregnant patients with high risk factors who got admitted in the Department of Obstetrics and Gynaecology at Care Hospital, Jamnagar during the period from May 2018 to September 2020. Background: High-risk pregnancies causes many adverse perinatal outcomes. Doppler ultrasound is a non-invasive technique to study the feto-maternal circulation to guide the clinical management. Objective: This study aims at evaluating the role of colour Doppler in high-risk pregnancies and their perinatal outcome. Materials and Methods: This was a prospective study carried out for 29 months in the Department of Radiology with antenatal women in the age group of 18-35 years with singleton pregnancy of gestational age of <28 weeks to >35 weeks having high-risk factors considered in study. The risk factors considered were pregnancy induced hypertension (PIH), gestational diabetes, anemia, oligohydramnios, polyhydramnios and IUGR. Doppler study of umbilical artery and fetal middle cerebral artery (MCA) arteries was done and amniotic fluid index (AFI) was measured. Parameters in the form of resistive index, pulsatility index, and systolic/diastolic ratio were taken. obstetric history was taken with regular interval follow up. Results: The study was carried out with 50 patients. High-risk pregnancy was more common in the age group of 21-25 years. The most common high-risk factor in pregnancy was oligohydramnios which accounted for 30% of cases. Out of 50 high-risk pregnancies, 5 (10 %) of cases resulted in intrauterine growth restriction (IUGR). Out of 50 high-risk cases, in 36 cases, umbilical artery findings were abnormal. 3 patients had intrauterine death (IUD) and 27 patients had poor perinatal outcome. Umbilical artery abnormality showed significant sensitivity and negative predictive value for adverse (poor + IUD) perinatal. Correlation was seen between high risk pregnancy and need of emergency caesarean section and induction and associated adverse perinatal outcome. Conclusion: Combination of different arterial waveform study enhance the diagnostic accuracy in identifying those intrauterine growth restricted foetuses that were at risk. Keywords: Colour Doppler, high risk pregnancy, perinatal outcome.

Background: Pre-eclampsia and IUGR are two conditions resulting from defective trophoblastic invasion of spiral arteries and an increase in vascular resistance in uteroplacental circulation. Doppler offers a non-invasive tool for evaluation of fetoplacental blood flow and correlate with fetal compromise giving early warning sign of fetal distress.Methods: The study was conducted in Command Hospital, Lucknow in 100 singleton pregnancies with vertex presentation between 28-40 weeks of gestation with severe preeclampsia and/or IUGR. Doppler analysis of UA and MCA was done. Pregnancies were terminated depending on clinical condition and Doppler results.Results: Abnormal Umbilical artery S/D ratio had strong statistical correlation with poor perinatal outcome. Elevated RI had 100% sensitivity in predicting APGAR<7 at 5 minutes. Elevated PI values was statistically significant in all parameters (except NICU stay>48hrs) in predicting poor perinatal outcome. PI values had highest sensitivity for predicting low APGAR values and highest specificity for predicting NICU admission. AEDF and REDF also correlated with adverse perinatal outcome. MCA S/D ratio had a high sensitivity (96.8%) in determining NICU stay>48h and specificity (70%) in determining NICU admissions. RI had highest sensitivity (71.8%) for NICU stay >48hrs and highest specificity for predicting NICU admissions (76.5%). MCA PI had a sensitivity of 66.6% in determining APGAR<7 at 5min and a specificity of 78.7% in determining NICU admissions. CPR had the highest sensitivity (100%) among all indices.Conclusions: The study showed an adverse fetal outcome in cases of severe preeclampsia and or IUGR which showed abnormal Doppler results and thereby help to determine the optimal time for delivery.

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.
