Obstetric and perinatal outcome & usefulness of umbilical artery doppler Velocimetry in cases of Oligohydramnios diagnosed after 34 weeks of gestation

Aim: To study the obstetrical and perinatal outcome and usefulness of umbilical artery Doppler velocimetry and AFI in oligohydramnnios at or beyond 34 weeks of gestation. Methods: This comparative randomized prospective study conducted among 150 pregnant women at 34 weeks to 42 weeks of gestation.AFI was measured by 4 quadrant technique and umbilical artery Doppler velocimetry done in cases with AFI5 cm and the results were statistically analyzed and compared. Results: In control group mean AFI was 11.74 cm and in study group it was 4.18cm.Among control group LSCS was 46%, in group 1and 2, 74% and 56% respectively. Occurrence of non reactive NST was more in oligohydramnios i.e. group 1 and 2 (42% & 28%) compared to 24% in control group. NICU admission were more in group 1 (58%) compared to group 2 (38%) and control group 22%. Conclusion: AFI 5 CM after 34 weeks of gestation is an an indicator of poor perinatal outcome and umbilical artery Doppler velocimetry is helpful in identification of high risk cases and reduced perinatal morbidity and mortality.
