Lesson plan
Selective reduction
triplets, a very rare condition where the triplets share a single placenta, seen on ultrasound. Because a single placenta has difficulty supporting multiple fetuses, in such cases a selective reduction to improve the likelihood of survival for the remaining fetus or fetuses may be indicated. Selective reduction is the practice of reducing the number of fetuses in a multiple pregnancy, such as quadruplets, to a twin or singleton pregnancy. The procedure is also called multifetal pregnancy reduction. The procedure is most commonly done to reduce the number of fetuses in a multiple pregnancy to a safe number, when the multiple pregnancy is the result of use of assisted reproductive technology; outcomes for both the mother and the babies are generally worse the higher the number of fetuses. The procedure is also used in multiple pregnancies when one of the fetuses has a serious and incurable disease, or in the case where one of the fetuses is outside the uterus, in which case it is called selective termination. The procedure generally takes two days; the first day for testing to select which fetuses to reduce, and the 2nd day for the procedure itself, in which potassium chloride is injected into the heart of each selected fetus under the guidance of ultrasound imaging.…
