Perinatal outcome associated with oligohydramnios at term

Abstract

Background: Oligohydramnios is a severe and common complication of pregnancy and its incidence is reported to be around 1 to 5% of total pregnancies. The aim of this study was to perinatal outcome of oligohydramnios (AFI <5) at term.Methods: A prospective study was conducted in which 200 patients at term with oligohydramnios AFI <5 cm with intact membranes were analyzed for perinatal outcome.Results: There were increased chances of FHR decelerations, thick meconium, increased LSCS, low Apgar score at 5 minutes, birth weight <2.5 kg, admission to NICU in pregnancy with oligohydramnios.Conclusions: An amniotic fluid index (AFI) of <5 cm detected after 37 completed weeks of gestation is an indicator of poor perinatal outcome. Determination of AFI can be used as an adjunct to other fetal surveillance methods that helps to identify those infants at risk of poor perinatal outcome.

Study of low amniotic fluid index and its effect on perinatal outcome

“…Gandotra et al also documented statistically significant association of LBW with oligohydramnios. 17 Naik et al also documented Oligohydramnios to be associated with higher incidence of low birth weight babies. 15 Literature suggest that oligohydramnios is associated with adverse perinatal outcome.…”

“…Similar findings were documented by Gandotra et al, where oligohydramnios was significantly associated with low Apgar score at 5 minutes and NICU admission. 17 Sharma et al also documented that majority of neonates born to mother with oligohydramnios required resuscitation and were admitted in NICU for more than 5 days. 18 Our study findings were similar to Naik et al in which oligohydramnios was associated with low Apgar score at 1 and 5 min, higher admission to NICU & Perinatal mortality.…”
