Background: Current study was carried out to assess the impact of isolated oligohydramnios on perinatal outcomes and mode of delivery.Methods: A retrospective observational cohort study was conducted at term pregnancy with sonographic finding of isolated oligohydramnios (AFI <5 cm) were recruited for the study. Uterine anomaly and high risk pregnancies were excluded from the study. The mode of delivery and perinatal outcome were compared with control group of pregnancy with normal amniotic fluid (AFI >5-25 cm).Results: When compared to the normal AFI, women with oligohydramnios had significantly lower birth weight babies and were delivered at a significantly earlier gestational age. However there was no difference in the APGAR scores at birth and NICU admissions between the two groups. Reactive NST had more chances of good APGAR score at 1 and 5 minute and that lower the AFI more the probability of nonreactive NST and abnormal Doppler. The number of inductions and caesareans done for foetal reasons were significantly higher in the exposed group.Conclusions: Obstetric and perinatal outcome remains similar in both isolated oligohydramnios with reactive NST as well as in patients with normal amniotic fluid index. Isolated oligohydramnios is not associated with adverse perinatal outcomes. However, it increases the risk for labour induction and caesarean section.

Background: Tobacco is known to be an established cause of adverse pregnancy outcome. Scientific studies, encompassing various ethnic groups, cultures and countries, have shown that cigarette smoking during pregnancy significantly affects mother, unborn fetus and the newborn baby.Methods: A hospital based cross sectional study was performed on 933 patients, separated in two groups: tobacco users and tobacco non-users and findings from each group were compared.Results: Incidence of complications like anemia, PIH and abruption increase with maternal usage of tobacco during pregnancy, chances of preterm delivery and ectopic pregnancy was raised, rate of wound complication was more in tobacco user women. There was no significant difference in mode of delivery.Conclusions: In the present study may establish association of tobacco consumption with adverse neonatal and obstetrics outcome and may encourage administration to focus on IEC (information, education, communication) to reduce tobacco consumption during pregnancy. Incidence of complications like anemia, PIH, abruption increase with maternal usage of tobacco during pregnancy. Chances of preterm delivery and ectopic pregnancy, was raised usage with of tobacco.
