What is amnioinfusion?

• A. A transhepatic infusion
• B. An oral infusion of fluid
• C. A transvaginal infusion of crystalloid fluid to compensate for oligohydramnios
• D. A intravenous infusion of medication to reduce amniotic fluid

Answer: (C)

Amnioinfusion is the transvaginal infusion of crystalloid fluid into the amniotic cavity during labor to increase amniotic fluid volume when oligohydramnios is present. The added fluid, usually normal saline or lactated Ringer’s, cushions the fetus and helps relieve umbilical cord compression, which can improve fetal heart rate patterns. It is delivered through a catheter placed through the cervix after membranes have ruptured and is used to compensate for oligohydramnios, not administered orally or intravenously to reduce amniotic fluid.
