Introduction; Oligohydraminos is most commonly defined as an amniotic fluid index (AFI) ≤ 5 cm or the largest vertical pocket measuring ≤ 2 cm . It is considered a risk factor for adverse fetal outcome, as well as an indicator of the possible presence of maternal and/or fetal comorbidities. Perinatal maternal morbidity and mortality are significantly increased in pregnancies with oligohydraminos. Objective: To compare perinatal and maternal outcomes among oligohydraminos and non oligohydraminos pregnancies. Methods: This is a cross sectional comparative study with prospective facility based follow up study was done with sample size is calculated to be 51 and 102 with ratio of 1:2 for oligohydraminos and non-oligohydraminos respectively. All pregnant women diagnosed to have Oligohydraminos and admitted to FHCSH and TGSH, high risk ward from April 1 - August 30/2019 was included in the study. The data was collected by a pretested structured questioner Using structured check list, information on their socio demographic factor, current obstetric factors and maternal and perinatal maternal outcomes was collected. The collected data was cleaned, coded and entered into EPI- data version 3.1. And then exported in to SPSS Version 23.0 for analysis. Strength of association between the explanatory variables and outcome variables was done described using odds ratio at 95% CI and P value less than 0.05. The results presented in tables and charts. Results: The CD rate in women with oligohydraminos was 61%, compared to 22% in non oligohydraminos group, statistically significant (P < 0.001). 5-min APGAR score <7 was observed in 20 (40%) neonates in oligohydraminos (p = 0.002) and 16(15%)in no oligohydraminos ,it is statistically significant. NICU admission was required for 14 (27 %) versus 11(10 %) babies in oligohydraminos and no oligohydraminos, respectively; this is found to be statistically significant (p = 0.011). Conclusions: Oligohydraminos has a significant correlation with adverse perinatal and maternal outcome.
