ASSOCIATION OF ABNORMAL AMNIOTIC FLUID VOLUME AND ABNORMAL DOPPLER IN THIRD PREGNANCY TRIMESTER WITH PRETERM BIRTH PREGNANT FEMALES

Abstract

Background: Perinatal mortality in India has been linked to preterm birth with it being considered as vital contributor. Preterm birth presents with incidence ranging from 13% to 19% of all live Indian births and has large interstate variations.
Aim: The present study aimed to assess the diagnostic efficacy and association of abnormal amniotic fluid volume (AFV) and abnormal Doppler in the third pregnancy trimester with preterm birth pregnant females.
Methods: The study assessed 289 females where the staging of fetal growth restriction, fetal structure, growth, and environment, estimation of preterm preeclampsia risk, ultrasound assessment, and fetal Doppler studies were done in the third trimester. Association in abnormal amniotic fluid volume and abnormal Doppler was assessed with preterm birth along with diagnostic efficacy of doppler and amniotic fluid volume.
Results: Among 315 females, 25.39% (n=80) of females had preterm birth before 37 weeks of gestation. In 190 females with normal fetal Doppler and abnormal AFV, 21.05% (n=40) had preterm birth. Preterm preeclampsia was associated with the preterm birth. The diagnostic efficacy of both AFV and abnormal fetal Doppler is good in predicting preterm birth.
Conclusions: The present study concludes that third-trimester fetal Doppler studies can help reduce the rate of preterm birth by helping in the assessment of fetal well-being which contradicts the belief that third-trimester fetal Doppler can lead to iatrogenic preterm birth. The association is present between preterm preeclampsia and preterm birth, and early identification in high-risk females and aspirin therapy initiation can have beneficial effects on preterm birth.
