JACKSONVILLE, Ill. — Heather Crivilare was a month from her due date when she was rushed to an operating room for an emergency cesarean section.

The first-time mother, a high school teacher in rural Illinois, had developed high blood pressure, a sometimes life-threatening condition in pregnancy that prompted doctors to hospitalize her. Then Crivilare's blood pressure spiked, and the baby's heart rate dropped. "It was terrifying," Crivilare said.
