Practice
The reduction procedure is generally carried out during the first trimester of pregnancy. The most common method is to inject potassium chloride into the fetus's heart; the heart stops and the fetus dies as a result. Generally, the fetal material is reabsorbed into the woman's body. While the procedure generally reduces the over-all risk level for the remaining fetus or fetuses, reduction does have its own risks, including the possibility that one or more of the remaining fetuses will also die.
Dr. Mark Evans, a New York City-based obstetrician-geneticist, and a group of doctors, developed the procedure for selective reduction in the 1980s.

Famous quotes containing the word practice:
“Theory can leave questions unanswered, but practice has to come up with something.”
—Mason Cooley (b. 1927)
“It is accordance with our determination to refrain from aggression and build up a sentiment and practice among nations more favorable to peace ... that we have incurred the consent of fourteen important nations to the negotiation of a treaty condemning recourse to war, renouncing it as an instrument of national policy.”
—Calvin Coolidge (1872–1933)
“Abused as we abuse it at present, dramatic art is in no sense cathartic; it is merely a form of emotional masturbation.... It is the rarest thing to find a player who has not had his character affected for the worse by the practice of his profession. Nobody can make a habit of self-exhibition, nobody can exploit his personality for the sake of exercising a kind of hypnotic power over others, and remain untouched by the process.”
—Aldous Huxley (1894–1963)
