COLOUR DOPPLER STUDY OF FOETOMATERNAL CIRCULATION IN PIH, OLIGOHYDRAMNIOS AND ITS PERINATAL OUTCOME
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2018, Vol 7, Issue 47
Abstract
BACKGROUND Hypertensive disorders of pregnancy are one of the most common complications that affect the mother. It is one of the leading causes of maternal and foetal morbidity and mortality. Oligohydramnios is defined by Phelan1 as AFI <5 cm but Jeng2 et al proposed a cut off of 8 cms demonstrating increased incidence of meconium staining, caesarean delivery for foetal distress. Abnormal foetal heart rate pattern and Apgar score of 7/less at one minute when AFI was < 8. The aim of the study is to evaluate and study the foetomaternal circulation using colour Doppler in hypertensive disorders of pregnancy and oligohydramnios in third trimester so that we may predict various complications that may arise and to follow the foetal outcome. MATERIALS AND METHODS This observational study has been carried out in the department of Obstetrics and Gynaecology, Sri Adichunchanagiri Institute of Medical Sciences, B. G. Nagara, in pregnant women attending OPD/admitted and satisfying the inclusion (PIH and oligohydramnios in third trimester) and exclusion criteria, during the period November 2012 to October 2014. Doppler study was conducted in all these high-risk cases. RESULTS Out of 100 high risk cases, 56% had hypertension, 24% had Oligohydramnios and 20% had both hypertension and Oligohydramnios. Majority of the patients (48%) were in the mean age group of 21-25 years. In uterine artery Doppler study, abnormal RI >0.6 was present in 11%, PI >1.1 in 25% and S/D ratio >2.6 in 24%. 39% showed persistence of notching in uterine artery. Umbilical artery Doppler revealed, abnormal RI >0.6 in 58%, PI > 1 in 39% and abnormal S/D ratio >3 in 29%. Majority were term at the time of termination. 58% of neonates had a mean birth weight of <2.5 kg. Meconium staining was present in 40 % of babies and low APGAR < 7 at 1 min and 5 mins in 19%. NICU admission was needed for 38% of babies. 12% perinatal mortality was observed. CONCLUSION Present study conducted in high risk pregnancies with Doppler parameters, revealed those with abnormal Doppler study had an adverse outcome. Hence, Doppler study has got a better prediction of adverse perinatal outcome and thus provide the obstetrician adequate time during which early intervention can be made, to improve foetal outcome.
