The Relation between Clinically Obvious Mild Unexplained Polyhydramnios and Poor Perinatal Outcome

Background and Objectives:The relation between clinically obvious polyhydramnios and poor perinatal outcome has been described . Much less is known about mild unexplained polyhydramnios which usually is initially suggested by sonography late in gestation. The purpose of the present investigation was to relate mild idiopathic polyhydramnios to perintal outcome. Materials and Methods: we selected 1000 pregnant women from five healthcenters overs 12 month period and performed sonographic examinations monthly after 26th week of gestation. All subjects had singleton gestations not complicated by conditions known to be predisposed to polyhydrarnnios. Mild polyhydramnios was defined sonographically as an amniotic fluid index of 24.1-39.9. Results: we dignosed mild polyhydramnios in 125 out of 1000 patients (12.5%) undergoing sonography at 26-42 weeks of gestation. The mild polyhydramnios group showed a significantly higher incidence of birth weight greater than 4000 gr than did the control group (18% versus 8.6%, p<0.05). Conclusion: we conclude that diopathic polyhydrarnnios in late gestation is relativily common. Except for a higher incidence of large for gestational age fetuses. This condition by itself is not associated with an increased risk of adverse perinatal outcomes.
