Patient's question:
NoDoctor's answer:
Oligohydramnios refers to a condition where the amniotic fluid volume is less than 300 milliliters during the late stage of pregnancy. The cause is unclear, but it may be related to an imbalance in amniotic fluid metabolism. When oligohydramnios occurs, the amniotic fluid appears viscous, cloudy, and dark green. Oligohydramnios poses significant risks to both the mother and fetus, primarily due to high uterine sensitivity, uncoordinated uterine contractions during labor, and prolonged labor. It can lead to varying degrees of fetal malformations, underdeveloped lungs, fetal distress, intrauterine growth restriction, and neonatal asphyxia. Statistics show that the perinatal mortality rate (from 28 weeks of gestation to 7 days after birth) is five times higher in cases of oligohydramnios compared to normal pregnancies, making it one of the key diseases requiring focused prevention and treatment.
