Pregnancy Outcome after Diagnosis of Oligohydramnios

Background. To determine the outcome of maternal and fetal wellbeing after diagnosis of oligohydramnios at term pregnancy. Methods 50 female pregnant patients aged between 18 to 27 yrs were screened with history of oligohydramnios by ultra sound scanning after 37 completed weeks, compared with 50 controls with no oligohydramnios. Results The meage age of study group were 22.7 years and of control group is 22.4yrs respectively. majority of the patients were primigravidas in both study and control group. The mean gestational age was 39.5wks in study groupand 39.4 wks in control group. the amniotic fluid index was measured by four quadrant semi quantitative technique in ultrasound and those with AFIless than5cm were considered as oligohydramnios, and those with AFI between 5cm& 20Cm were considered. the occurrence of nonreactive nstwas more in study group compared to control group. the incidence of meconium stained liquor was more (52 %) instudy group compared to control group (26 %). the induction of labour was more commonin study group (46 %) than control group (24 %), which is statistically significant. the efficacy of AFI as ascreening test to predict fetal distress is more significant with positive predictive valueof 57 % and negative predictive value is 80 %. the mean birth weight was 2.5 kg instudy group compared to 2.75kg in control which is statistically significant.34 % of the new borns were admitted to nicu in study group compared to 14 % of control group. Conclusions In the presence of oligohydramnios, the occurrence of non reactive NST, meconium stained liquor, Development of foetal distress are very high. and. the rate of lscs,. the low 5 min apgar score, , low birth weight and perinatal morbidity are high compared to controls without oligohydramnios.
