Background: Decrease in amniotic fluid is known as "Oligohydramnios". It is correlated with adverse maternal and perinatal outcomes in terms of intrauterine growth retardation, me conium aspiration syndrome, low birth weight, low APGAR scores, congenital anomalies and increase rate of caesarean deliveries. Early detection of Oligohydramnios and its management may help in reduction of maternal andperinatal morbidity and mortality. Objective: To find out maternal and fetal outcome of oligohydroamnios. Methods: This was a cross-sectional observational study conducted in the Indoor patient Department of Obstetrics & Gynecology in Tairunnessa Memorial Medical College and Hospital, Gazipur, Bangladeh from January 2016 to June 2016. The study was conducted in oligohydroamniotic patient admitted in the same ward. Fifty patients Included in your study. Complete history was taken from patients and their accompanying attendants. Thorough clinical examination was done. Relevant investigations report was collected. All the information was recorded in the fixed protocol. Collected data was classified, edited, coded and entered into the computer for statistical analysis by using SPSS-19. Results: Out of 50 cases mean age was 24.56 (±4.71) years, majority 27(54%) were primigravida and 23(46%) were multi gravida. Majority 27(54%) delivered bycaesarean section and 23(46%) were delivered by normal vaginal delivery. Mainindication for caesarean section 25.93% fetal distress, 18.52%malpresentation, 18.52% previous LSCS and 37.03% severe Oligohydramnios. Prevalence of SGA babies (62%) is almost double than AGA babies (38%). Factor associated with oligohydramnios were PIH, malpresentation, chronic abruption, prolong pregnancy, post term pregnancy, fetal congenital anomalies were 16%,04%, 18%, 28%, 06%, 20% and 18% respectively Eighty two percents pregnant women were borderline oligohydramnios and 18% were severe oligohydramnios. Most of 88% patients had confirmed by ultrasonographically. The various perinataloutcomes, including Low birth weight, IUGR babies, perinatal death, APGAR score< 7 at 5 min, admission in neonatal ward etc. Among 50 babies, low birth babies were 62%, APGAR score < 7 was found in 18% of babies, 26% babies wereadmitted in neonatal intensive care unit. Among 50 babies perinatal death (Stillbirth+Neonatal death) was 10% and 1 baby born with congenital anomaly (2%). Conclusion: In conclusion majority delivered by caesarean section, main indication forcaesarean section was fetal distress, malpresentation, previous LSCS and severe Oligohydramnios. Factor associated with oligohydramnios were PIH, malpresentation, chronic abruption, prolong pregnancy, Post term pregnancy, fetalcongenital anomalies. Eighty two percents pregnant women were borderline oligohydramnios. Various perinatal outcomes, including Low birth weight, IUGRbabies, perinatal death, APGAR score < 7 at 5 min, admission in neonatal ward. Perinatal death (Still birth+Neonatal death) was 10% and 1 baby born with congenital anomaly.
