Amnioinfusion
Amnioinfusion
Amnioinfusion (pronounced am-nee-oh-in-fyoo-zhun) is a medical procedure that involves the introduction of a saline solution into the amniotic sac during labor or pregnancy. This procedure is typically performed to alleviate complications associated with low levels of amniotic fluid, or oligohydramnios.
Etymology
The term "amnioinfusion" is derived from the Greek words "amnion" (meaning "membrane around the fetus") and the Latin word "infusio" (meaning "to pour in").
Procedure
During an amnioinfusion, a thin catheter is inserted into the uterus through the cervix. The catheter is then used to deliver a sterile saline solution into the amniotic sac. This procedure can be performed during labor to alleviate complications associated with low levels of amniotic fluid, or it can be performed during pregnancy to improve the accuracy of certain diagnostic tests.
Indications
Amnioinfusion is typically indicated for conditions such as oligohydramnios, thick meconium staining of the amniotic fluid, and variable decelerations of the fetal heart rate during labor. It may also be used to improve the accuracy of ultrasound examinations when there is insufficient amniotic fluid.
Risks and Complications
While amnioinfusion is generally considered safe, it does carry some risks. These can include infection, premature rupture of membranes, and umbilical cord complications. It's important for patients to discuss these risks with their healthcare provider before undergoing the procedure.
