Perinatal Outcome in Idiopathic Polyhydramnios

Area of Science:

• Obstetrics and Gynecology
• Perinatal Medicine
• Maternal-Fetal Medicine

Background:

• Idiopathic polyhydramnios, characterized by excessive amniotic fluid without a clear cause, presents a clinical challenge in managing pregnancy outcomes.
• Understanding the specific risks associated with idiopathic polyhydramnios is crucial for timely intervention and improved perinatal care.

Purpose of the Study:

• To investigate and compare perinatal outcomes in pregnancies complicated by idiopathic polyhydramnios versus normal pregnancies.
• To identify the specific maternal and fetal complications associated with idiopathic polyhydramnios.

Main Methods:

• A case-control study involving 500 pregnant women with idiopathic polyhydramnios and 500 controls.
• Perinatal outcomes, including delivery mode, preterm birth, maternal complications, and perinatal mortality, were recorded and compared between the groups.

Main Results:

• Idiopathic polyhydramnios was most frequently diagnosed between 28 and 36 weeks gestation, predominantly as mild cases.
• While rates of preeclampsia, gestational hypertension, and normal vaginal delivery were similar between groups, preterm deliveries were significantly higher in the idiopathic polyhydramnios group (54%).
• Maternal complications (51.8% vs 13.6%) and perinatal mortality (10.4% in study group) were substantially elevated in pregnancies with idiopathic polyhydramnios.

Conclusions:

• Idiopathic polyhydramnios is a significant risk factor for adverse perinatal outcomes.
• Pregnancies with idiopathic polyhydramnios are associated with increased perinatal morbidity and mortality compared to uncomplicated pregnancies.
