A cross-sectional study of Pregnancy and its outcome with special reference to oligohydramnios and polyhydramnios at tertiary care center

Abstract

Background: The importance of amniotic fluid volume as an indicator of fetal wellbeing has made its assessment an important part of antenatal fetal surveillance, also the level of amniotic fluid affect the fetal well being so the present study was conducted to study the pregnancy and its outcome with special reference to oligohydramnios and polyhydramnios. Methodology: We studied 200 clinically suspected cases of oligohydramnios and polyhydramnios of more than 28 weeks of gestational age at Govt. Medical College Akola Maharashtra. All these clinically suspected patients were further examined by ultrasonography for fetal surveillance, AFI calculation and confirmation of amniotic fluid level abnormality. Result: The study revealed that predisposing factors and complications associated with oligohydramnios were – post term pregnancies, PROM, PIH, chronic abruption placentae while for polyhydramnios they were preeclampsia, PROM, preterm labour, abruption placentae, malpresentation. There were no maternal high risk factors seen in oligohydramnios but polyhydramnios was observed with anemia, Rh factor incompatibility, PIH, gestational diabetes mellitus and multifetal gestation. The proportion of C-section for fetal distress was higher in oligohydramnios. Conclusion: We concluded from this study that there were many predisposing factors for both oligohydramnios and polyhydramnios they should be addressed judiciously to reduce their higher proportion. Hence it is essential to evaluate amniotic fluid volume during ante partum fetal surveillance, while maternal examination should look for high risk factors to avoid untoward complications beforehand. Thus management of women with oligohydramnios and polyhydramnios should be indivisualised with careful monitoring during labour, judicious and active intervention timely gives margin of safety.
