Hydration therapy in oligohydraminos in Ain Shams University Maternity Hospital: Randomized Controlled Clinical Trial

Abstract

Abstract Background Amniotic fluid surrounds the fetus within first gestational weeks. acts physiologically and anatomically in a protective manner preventing fetal and umbilical cord compressive forces, besides have antibacterial features keeping the fetal temperature stable, and avoiding adhesive attachment to developing fetal membrane system. Amniotic fluid volume and constituents continuously change in a dynamic manner as the gestation progresses. Sufficient amniotic fluid volume is crucial for fetal mechanophysiological well-being adding in normal musculoskeletal wellbeing besides aminiotic fluid consituents refelect physiological integrity of fetal systems particularly the renal and gastrointestinal systems. Objective The aim of this study is to find out if there is significant increase in amniotic fluid index after acute maternal hydration in pregnant women with oligohydraminos and to evaluate therapeutic effectiveness of two different modalities of hydration therapy. Methods We conducted randomized controlled open labeled clinical trial on 300 cases with oligohydraminos admitted to Ain Shams University Maternity Hospital (ASUMH) in the period from September 2019 to March 2020. These patients were classified to three groups, Patients in group A were Oral hydration group: 100 participants while Patients in group B were Intravenous hydration group: 100 participants, patients in Group 3 No hydration group: 100 participants. Results The demographic data analysis of the current study have shown that there was no statistical significant difference between the investigated research groups as regards the demographic characteristics (age, BMI, Parity gestational age p values 0.171,0.370,0.840,0.290 consecutively). The study results also showed that oligoydramnios recurrence frequency was highest among control group, followed by intravenous group and least in oral group, the differences were statistically nonsignificant. Conclusion Hydration can be considered an effective way of decreasing the chance of oligohydraminos because maternal dehydration increases the chance of the condition. Therefore both serum and oral hydration therapies are hypothesized to be effective treatment for oligohydraminos. Previous studies have supported this hypothesis. Maternal hydration may theoretically increase amniotic fluid volume may by causing fetal diuresis.
