Uterine artery Doppler in first trimester in prediction of adverse pregnancy outcome in Dharmapuri district of Tamil Nadu

Bindu S.


Background: Pregnancies are complicated by hypertensive disorders of about 5-10% and hemorrhage, sepsis, and fetal growth restriction constitute a triad contributing to maternal morbidity and mortality. Hypertensive disorders in pregnancy vary from mildly elevated blood pressure to severe hypertension with multi-organ dysfunction. The study aims to evaluate the first-trimester uterine artery Doppler in the prediction of the development of adverse pregnancy outcomes.

Methods: This prospective longitudinal observational was done in Dharmapuri Medical College and Hospital were selected for this study. Totally 150 pregnant women were included in the study. 75 were controls and 75 cases. The study period was from June 2018 to February 2019. Evaluating the optimal definition of abnormal first trimester.

Results: Previous obstetric history in the study population. In the study group 3% of bad obstetric history (BOH) present. In the case group, 5% has BOH due to 2 neonatal death and 2 term intrauterine device (IUD), uterine artery Doppler parameters to predict adverse pregnancy outcomes, and association of gestational hypertension in the study groups. In the control group, 1%, and the case group 5% of them had gestational hypertension. Out of 4, 3 had an average uterine artery Doppler more than 2.3 (maximum of 2.7) and 1 had single uterine artery Doppler abnormality.

Conclusions: The study showed that first-trimester uterine artery Doppler with single and average uterine artery pulsatility index (PI) >95th centile (2.3) has a better screening value in my population. The overall performance of the first-trimester uterine artery Doppler in the prediction of adverse pregnancy outcomes is valuable.
