Umbilical Artery Doppler Indices Better Predictor for Perinatal and Obstetrics Outcone in Oligohydromnios at or Beyond 34 weeks of gestation

Aim:  To compare the  usefulness of umbilical artery Doppler velocimetry in predicting the obstetrical and perinatal outcome in  oligohydramnnios at or beyond 34 weeks of gestation.                                                                             Methods:  This comperative  prospective study conducted among 50 pregnant women at 34 weeks  of gestation with oligohydramnios( AFI £ 5 cm) .They are divided in to two groups.The study group(n=21) consist of oligohdramnios at or beyond 34 weeks gestation with abnormal doppler and control group (n=29) with oligohydramnios with normal doppler.  Results were statistically analyzed and compared using various variables of perinatal outcome.. Results:  In the study  group the 28% cases in the AFI range of 1-2cm and none in control and 46.6% cases in study group were 4-5cm where as 79% of cases in control group.Among control group 65.5% had a LSCS while 34.5% delivered vaginaly and in study group 85.7% had  LSCS and 14.3% devilered vaginaly.LSCS for fetal distress in study group were 42.8% and in control group 32.4% In study group IUGR were 80.9% , NICU admission were 76.19% where as in control group IUGR were 34.48% & NIUC admission were 44.88%.                                                                                                                            Conclusion:oligohydramnios with normal flow velocimetry are at lower risk than those with abnormal  umbilical artery Doppler velocimetry.Cases with anbnormal Umbilical artery Doppler velocimetry were taken directly for LSCS ,which reduced , the perinatal morbidity and mortality.Hence in all patients with oligohydramnios, Umbilical artery Doppler velocimetry  should be done to recognize the compromised fetus.
