A randomized clinical trial comparing the effect of maternal intravenous hydration and placebo on the amniotic fluid index in oligohydramnios.

Objective: To compare the treatment of acute intravenous hydration with placebo in term pregnant women manifesting oligohydramnios.

Methods: All patients with oligohydramnios who met the inclusion criteria were offered participation in this randomized, double-blind, placebo-controlled study. After ruling out rupture of membranes and maternal and fetal complications, we recruited 44 women with third trimester singleton pregnancies having an amniotic fluid index (AFI) of less than 6.
