Moreover, the rate of labor induction has more than doubled from 9.5 percent In 1990 to 22.3 percent In 2005, and currently accounts for approximately 24 percent of Infants born between 37 and 41 weeks gestation In the U.S.* The rate of induction of labor has also increased for prete Ebook High-risk and critical care obstetrics: Part 2rm gestations.
