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

Abstract

A mniotic fluid gradually surrounds the developing fetus and acts physiologically and anatomically in a protective manner preventing fetal and umbilical cordcompressive forces, besides having 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 musculoskeletal normal development and physiological systems maturity and well-being such as pulmonary development besides amniotic fluid constituents reflect physiological integrity of fetal systems particularly the renal and gastrointestinal systems. Aberrations in amniotic fluid volume (AFV), both low (oligohydramnios) and high (polyhydramnios), are associated with multiple adverse pregnancy outcomes. Oligohydramnios clinically defined as reduced amniotic fluid volume assessed by sonographic features such as AFI below 5 cm and an AFI under the 5th centile for the corresponding gestational age. Oligohydramnios affects around 8.2% of antepartum pregnancies, and present in about 37.8% of laboring cases, and have been correlated to statistically significantly raised perinatal morbidity and mortality issues The aim of this study is to find out if there is significant increase in amniotic fluid index after maternal hydration in pregnant women with oligohydraminos.
