Fetomaternal outcome in abnormal liquor volume pregnancies

Background Variation in the amniotic fluid reflects fetal compromise, and congenital anomalies and also may predict perinatal morbidity and mortality.

Methods Singleton pregnancy subjects with well-established dates at ≥28 weeks of gestational age were taken into study. These subjects were ultrasonographically diagnosed to have abnormal liquor volumes. This study was a hospital-based single-center prospective observational study conducted in Midnapore medical college and hospital, west Bengal. The chi-square test was applied for statistical significance and a p<0.05 was considered to be significant.

Results In all subjects of abnormal liquor volume, the incidence of oligohydramnios and polyhydramnios are in the proportion of 3:1 in our study. Postdated pregnancy (28.4%), hypertensive disease (16.8%), intrauterine growth restriction (IUGR) (12.6%), and anemia (2.2%) were associated with oligohydramnios. Congenital anomalies (23.3%), GDM (16.6%), and Rh-incompatibility (3.3%) were associated with polyhydramnios. The incidence of caesarean section, meconium-stained liquor and 5-minute APGAR score <7 and NICU admission was higher in the oligohydramnios group as compared to polyhydramnios. In abnormal liquor volume, the statistical association was significant with onset of labour (p=0.00), mode of delivery (p=0.00), the colour of liquor(p-0.00), and fetal outcome (p=0.00).

Conclusions Postdated pregnancy, IUGR, and hypertensive disorders were associated with oligohydramnios and congenital anomalies, and GDM and Rh-isoimmunization were associated with polyhydramnios. In abnormal liquor volume onset of labour, mode of delivery, the colour of the liquor, and fetal outcome were significant.
