Oligohydramnios overview

#shorts #oligohydramnios #overview #pillshill Oligohydramnios refers to the amniotic fluid volume that is less than expected for gestational age. It is typically diagnosed by ultrasound examination and may be described qualitatively (eg, reduced amniotic fluid volume) or quantitatively (eg, amniotic fluid index less than 5 cm, single deepest pocket less than 2 cm). Oligohydramnios may be idiopathic or have a maternal, fetal, or placental cause. The fetal prognosis depends on several factors, including the underlying cause, the severity (reduced versus no amniotic fluid), and the gestational age at which oligohydramnios occurs. Because an adequate volume of amniotic fluid is critical to normal fetal movement and lung development and for cushioning the fetus and umbilical cord from uterine compression, pregnancies complicated by oligohydramnios from any cause are at risk for fetal deformation, pulmonary hypoplasia, and umbilical cord compression. Oligohydramnios is associated with an increased risk for fetal or neonatal death, which may be related to the underlying cause of the reduced amniotic fluid volume or due to sequelae of the reduced amniotic fluid volume.
