Aim To assess feto-maternal outcome of pregnancies with polyhydramnios.

Background The incidence of polyhydramnious is around 1% of all pregnancies. Prognosis depends on the cause of polyhydramnios. Currently no guidelines are available to manage pregnancies with polyhydramnios. This study was hence undertaken to look into the feto-maternal outcomes and propose guidelines to treat patients with polyhydramnios.

Materials and Methods Retrospective study was undertaken over 8 months. 80 patients were identified and 48 cases were included in the study. The correlation of diabetes, risk of Down's syndrome, abnormal anomaly scans and positive blood investigations (glucose tolerance tests, TORCH and Parvo virus testing) were studied.

Results 48 patients were included in our study. 38% of the cases were primi gravid. 17% had family history of diabetes and 4% had a high Down's syndrome risk. 4% had positive anomaly scans. 6 patients had deepest vertical pool as a criterion to diagnose polyhydramnios and the rest were diagnosed using amniotic fluid index. Glucose tolerance testing was offered to 85% of the cases and TORCH and parvo testing was offered to 83% of the patients. 15% of the GTT tested were positive and 32% of TORCH testing was positive for IgG. Majority of the patients delivered after 37 weeks of gestation. 25 of the patients had normal vaginal delivery.

Conclusion GTT should be offered to all patients with polyhydramnios whereas TORCH and parvo testing should not be routinely recommended.
