Effect of Maternal Intravenous Hydration in Management of Oligohydramnios and The Changes in the Fetal Doppler

Abstract

Background and aim: Oligohydramnios is linked to different fetal and maternal conditions. Maternal hydration improves amniotic fluid content, because it promotes uteroplacental perfusion. The current work aimed to determine the results of intravenous hydration on the amniotic fluid index (AFI) and Doppler measurements of uteroplacental blood circulation during pregnancy with the third trimester oligohydramnios.
 Patients and methods: The current including 50 pregnant women in their third trimester with oligohydramnios. They were selected from the outpatient clinic at Al-Azhar University Hospitals. All were submitted to clinical evaluation by history and examination, followed by abdominal ultrasound and intravenous hydration therapy. Values before and after hydration were compared, delivery mode and fetal outcome were documented.
 Results: Maternal age was 30 ± 2.28. The majority of them were multigravida (58.0%) and higher percentage were multiparous (70.0%). The GA at delivery ranged between 32 and 37 weeks of gestation. There was a significant reduction of pulse, mean arterial pressure, temperature, hematocrit after hydration than before hydration. The birth weight ranged between 2765 and 3654 g. AF volume, AMF and uterine artery PI were significantly increased while umbilical artery PI was statistically decreased after hydration that corresponding values before hydration. The mode of delivery was normal vaginal delivery among 34% and cesarean section among 66.0% and the mean Apgar score was 7.8±1.9 and 8.9±0.87 at the first and fifth minutes, respectively.
 Conclusion: Intravenous maternal hydration therapy was safe and effective in terms of improvement of amniotic fluid index in pregnant females with isolated oligohydramnios in the third trimester. It enhanced the amniotic fluid volume and AFI in females with oligohydramnios.
