Perinatal Outcome in Idiopathic Polyhydramnios.

OBJECTIVES To study perinatal outcome in idiopathic polyhydramnios. METHODS Case-control study was conducted in 500 pregnant women with idiopathic polyhydramnios (study group) and 500 normal pregnant women (control group) attending the outpatient department of SHKM Medical College, Haryana. Perinatal outcomes were recorded in both the groups. RESULTS Out of 500 cases with idiopathic polyhydramnios, maximum cases were diagnosed between 28 and 36 weeks of pregnancy (84.6 %), and maximum presented with mild polyhydramnios (82 %). In the study and control groups, there were no statistically significant differences in preeclampsia and gestational hypertension (p = 0.445 and p = 0.230). In the study and control groups, 74.6 and 79.6 % women, respectively, had normal vaginal delivery (p = 0.250). The study group recorded much higher number of preterm deliveries than the control group (54 %) (p = 0.000). In the study group, 51.8 % women had maternal complications, while in the control group, 13.6 % women had obstetrical complications. The study group recorded higher perinatal mortality (10.4 %) than the control group. CONCLUSIONS Idiopathic polyhydramnios is associated with higher perinatal morbidity and mortality than normal pregnancy.
