AbstractAmniotic fluid is a dynamic medium that plays a significant role in fetal well-being. It is essential during pregnancy for normal fetal growth and organ development. About 4% of pregnancies are complicated by oligohydramnios. It is associated with an increased incidence of perinatal morbidity and mortality due to its antepartum and intrapartum complications. Gerbruch and Hansman described a technique of Amnioinfusion to overcome these difficulties to prevent the occurrence of fetal lung hypoplasia in pregnancies complicated by oligohydramnios. Amnioinfusion reduces both the frequency and depth of FHR deceleration. The mechanisms through which amnioinfusion acts include mechanical cushioning of the umbilical cord to prevent recurrent umbilical compressions that lead to fetalacidemia, predisposition to meconium aspiration Syndrome (MAS).
