Abstract

Morbidity is seen in pregnancies with oligohydramnios due to various complications like, cord compression and subsequent distress, deformity due to intra-amniotic adhesions, decreased fetal weight, fetal hypoxia,Fetal pulmonary hypoplasia. Present study was conducted to find out the value of oligohydramnios in perinatal outcome and maternal outcome in pregnancies beyond 37 completed weeks. Material and Methods: Present study was cross-sectional study, conducted in pregnant women with Gestational Age Between 37 to 40 weeks, amniotic fluid index of ≤5 cm, Intact membranes., Singleton pregnancy with cephalic presentation. Results: Our study was performed in tertiary care center with AFI ≤5 cm and gestational age between 37 to 40 weeks. Majority of pregnant women were from 21 to 25 years of age group i.e. 59%, followed by 21% from 26 to 30 years age group. Mean age was 23.8±3.29 years. Majority (86%) were booked cases. 41% of cases were primigravida and remaining 59% were multi. Majority belongs to 38 weeks of gestation followed by 33% were from 39 weeks of gestation. Mean gestational age of cases was 38.38±0.90 weeks. Trial of labour given to 31% subjects and 69% cases were directly undertaken for LSCS. Majority underwent LSCS (86%) and only 14% were normally delivered. Out of 86 LSCS carried out, majority 63(73.3%) having fetal distress followed by history of previous LSCS in 21 (24.4%) NICU admission was indicated in only 22% of newborn of women. Out of 100 delivered babies, newborn death incidence was 6%. All 6 neonates admitted in NICU were died (100%) incidence. Out 94 who survived, NICU admission was required in only 17% (16) newborns. This difference was highly significant. NICU admission required in 59.1% cases with AFI 0-2 as against 36.4% in AFI 2-4 and 4.5% with AFI >4. The difference was statistically significant. Neonatal death occurred in 83.3% cases with AFI 0-2 as against 16.7% in AFI 2-4. The difference in proportion was significant (<0.05) and there is association between NICU admission and AFI grades LSCS took place in 39.5% cases with AFI 0-2 as against 47.7% in AFI 2-4 and 12.8% with AFI > 4 & difference was statistically significant. Conclusion: In oligohydramnios, the occurrence of non-reactive NST, meconium stained liquor, development of fetal distress, the rate of LSCS, low 1 and 5 minute Apgar score, low birth weight, NICU admission, perinatal morbidity and mortality are more.
