Amnioinfusion is a procedure where IV fluids are infused into the uterus during labor to relieve umbilical cord compression and alleviate fetal distress caused by prolonged variable decelerations associated with low amniotic fluid levels (oligohydramnios). Nurses assist physicians with amnioinfusion by helping with catheter placement, monitoring infusion rates and fetal heart tones, and discontinuing the procedure if complications arise like increasing uterine tone or signs of fetal compromise. They also carefully document details of the procedure.
