Borderline oligohydramnios in term pregnancy and it's relation with pregnancy outcome

Background Oligohydramnios can lead to contamination of amniotic fluid, fetal distress, neonatal asphyxia, aspiration pneumonia, increased perinatal mortality and adverse pregnancy outcomes. Because of atypical clinical symptoms, the critical point is to treat patients with oligohydramnios in late pregnancy. The objectives of the research were to study the mode of delivery/rate of operative interference/incidence of cesarean section due to fetal distress/non-reassuring fetal heart rate status in cases of term pregnancy with borderline amniotic fluid index (AFI), and to study the perinatal outcome in cases of term pregnancy with borderline AFI.

Methods The study is a prospective comparative study to be conducted in patients attending antenatal clinic at department of obstetrics and gynaecology, Tirunelveli government medical college hospital from from January 2018 till January 2019 (12 months). Data collected with regards to age, demographic characteristics, and socioeconomic status, detailed history including patient’s complaints, duration of complaints, menstrual and obstetric history, significant past, family and personal history. 265 cases of borderline oligohydramnios were detected of which 150 cases were selected for the study after applying exclusion criteria.

Results APGAR scores between the two groups. The mean APGAR scores of the normal group were 8.3±0.7 and the same of the borderline AFI group was 8.0±0.9. The difference between the means was statistically highly significant (p<0.01).

Conclusions Cumulative analysis of various studies, it will be reasonable to conclude that antepartum surveillance for borderline oligohydramnios is indicated in cases associated with fetal growth restriction or suboptimal fetal growth.
