Low amniotic fluid during pregnancy: How is it treated?
Your baby excretes about 16 fl oz ( half a liter) of urine daily and at 35 weeks the amniotic fluid reaches a peak volume of 2 pints ( 1 liter). After this time the volume starts to decline and can be as little as 3.5-7 fl oz ( 100-200 ml) in a pregnancy that is post mature ( overdue).
Low levels of amniotic fluid can be a sign of a growth-restricted baby or a baby with kidney problems, while excessive amniotic amniotic fluid may be seen in twin pregnancies and is sometimes associated with physical abnormalities in the baby or diabetes in the mother.
Few effective treatments exist for low amniotic fluid (oligohydramnios).
It's possible to temporarily increase the amount of amniotic fluid with a procedure known as amnioinfusion, in which saline is instilled into the amniotic sac. The effect is short-lived, however.
During prenatal care, amnioinfusion is usually done only to enhance ultrasound images. In this case, the saline is injected into the amniotic sac through a needle placed in the abdominal wall. Treatment will depend on what's detected through the ultrasound. Amnioinfusion might also be done during labor to relieve pressure on the umbilical cord. In this case, the saline is instilled into the amniotic sac through a catheter placed in the cervix. If the baby's heart rate drops too low or too often during labor or the umbilical cord is compressed, a C-section might be needed.
