Background: Oligohydramnios has been associated with a higher risk of labor induction
and cesarean birth, as well as a higher risk of maternal morbidity. This study was done
to compare between Non-Stress Test and Doppler Velocimetry in oligohydramnios for
maternal & fetal outcome beyond 34 weeks of pregnancy.
Methods: Patients with oligohydramnios <5cm with more than 34 week of gestation and
having normal NST and Normal color doppler were managed conservatively and
followed up to term.After collection of all data in Microsoft Excel and statistical analysis
was done by using SPSS version 22 with significant value (P value < 0.05).
Results: The majority (54.7%) of patient with oligohydramnios were in the age group
between 26-35 years. APGAR less than 7 was significantly more among groups C
(Doppler Normal/NST Abnormal) and D (Doppler Abnormal/NST Abnormal). NICU
admission was significantly more among group D. The mean NICU stay was
significantly more among groups B (Doppler Abnormal/NST Normal) and D. The mean
weight at birth was significantly more among groups A (Doppler Normal/NST Normal)
and C. The sensitivity and specificity of Doppler (78.60, 82.50) was more as compared to
NST (62.5, 61) in prediction of perinatal outcome.
Conclusion: This study concluded that Doppler is a stronger indication of early Fetal
impairment than NST because NST detects acute events in the presence or absence of
chronic hypoxia, but Doppler detects chronic alterations.
