Selective Reduction
A procedure to reduce the number of fetuses in a multiple pregnancy to improve outcomes for remaining fetuses.
Full Definition
Selective reduction, also known as multifetal pregnancy reduction, is a procedure performed in the first trimester to reduce the number of fetuses in a higher-order multiple pregnancy (triplets or more) to twins or singleton. The procedure aims to reduce risks associated with multiple pregnancies including preterm birth, low birth weight, and maternal complications. It involves the injection of potassium chloride into selected fetal hearts under ultrasound guidance. The decision for selective reduction involves complex medical, ethical, and psychological considerations.
