Severe Oligohydramnios at Mid trimester: Maternal hydration- A case report

Abstract

A case of severe oligohydramnios diagnosed at 23 weeks of pregnancy is presented. She is a known hypertensive on multiple drugs and had chorionic villous sampling at 12 weeks for molecular diagnosis. Diagnosis was based on ultrasound measurement of amniotic fluid index, while other evaluations including umbilical artery doppler studies, fetal anatomy and placenta maturity were essentially normal. Mainstay of management was combined intravenous/oral maternal hydration, bed rest, modification of antihypertensive regimen and close fetal surveillance. The amniotic fluid index returned to normal range and fetal growth has remained satisfactory. The emphasis of the case presentation is the role of maternal hydration in the management of idiopathic oligohydramnios.
