Oligohydramnios happens in 1-5% of term pregnancies. The clinical significance of isolated oligohydramnios been a matter of debate. We aimed in this study to investigate the impact of isolated oligohydramnios on the mode of delivery and risk of adverse perinatal outcome.
Retrospective study conducted in Armed Forces Hospitals of Southern Region, comparing cases with oligohydramnios (amniotic fluid level index <5) to normal amniotic fluid cases (amniotic fluid level index ≥ 8). Primary outcomes are the mode of delivery and adverse perinatal outcomes (including mortality, NICU admission, low Apgar score and sepsis)
