Fetal reduction
Selective termination of one or more fetuses in multiple pregnancies to improve outcomes for remaining fetuses.
Full Definition
Fetal reduction, also known as selective reduction or multifetal pregnancy reduction, is a procedure involving the selective termination of one or more fetuses in higher-order multiple pregnancies (triplets or greater) to reduce maternal and perinatal morbidity and mortality. The procedure is typically performed between 11-13 weeks gestation using ultrasound guidance to inject potassium chloride into the fetal heart. Fetal reduction aims to optimize outcomes by reducing risks associated with extreme prematurity, low birth weight, and maternal complications. The procedure requires careful counseling regarding risks, benefits, and ethical considerations, with decisions individualized based on specific circumstances.
