Polyhydramnios: ultrasonographic detection, associated risk factors and perinatal outcome
Prerna Gupta, Sangeeta Sen
Objectives: Detection of polyhydramnios by ultrasonography and studying its associated risk factors and following up for its perinatal outcome were the objectives of this study. Methods: It was an observational study in which 70 antenatal cases of polyhydramnios from 20-42 weeks of gestation were taken into consideration, irrespective of age and parity. Results: Out of total 70 patients in the study, 42.8% were diagnosed at gestational age of 33-37 weeks. Forty (57.14%) cases were having mild polyhydramnios. Thirty eight (54.28%) cases had no associated risk factors. In rest of cases congenital malformation 24.27% and diabetes 7.14% were associated as the risk factors. Forty (57.1%) pregnancies had no complication but 10% developed preterm labor. Thirty six (51.42%) cases had normal vaginal delivery and 31.42% had caesarean section. Fifty three (75.71%) of newborns were alive but 17.14% had neonatal death. Conclusion: Most cases were diagnosed after 28weeks and most had idiopathic and mild polyhydramnios. Diabetes and congenital malformation were the most frequent associated risk factors. Preterm labor represented the most frequent complication. Caesarean section as a mode of delivery was higher.
