A. "We need to decrease the fluid in your uterus." An amnioinfusion adds sterile fluid to the uterus, not decreases it. B. "The decreased fluid in the uterus is causing the baby to lie on the umbilical cord." Amnioinfusion is commonly performed when oligohydramnios (low amniotic fluid) is present, and it helps relieve pressure on the umbilical cord, which can result in fetal distress. C. "You need extra amniotic fluid to prevent a dry birth." A "dry birth" is not a recognized medical term or condition related to amnioinfusion. D. "This will replace fluid in your uterus to prevent an infection." Amnioinfusion is not used to prevent infection. Its purpose is typically to relieve umbilical cord compression or dilute meconium in the amniotic fluid.
