<font color="0000ff">Induced Births Cut Toll of Preeclampsia, Study Finds

Sept. 19 (Bloomberg) -- The number of fetuses and newborns who
die because of a condition their mothers develop while pregnant has
fallen as doctors perfect their timing in inducing labor, a new
study shows.
Doctors in Norway are inducing deliveries earlier for pregnant
women with preeclampsia, a condition marked by high blood pressure
and protein in the urine, boosting survival for both mothers and
their babies, according to the study, published today by the
Journal of the American Medical Association.
Doctors have been trying to balance the need to give a baby as
much time as possible in the womb with the medical strain on the
mother.
``There have been great advances in timing the delivery, so it
benefits the baby and the mother,'' said Olga Basso, one of the
study's authors and a researcher at the National Institute of
Environmental Health Sciences in North Carolina. ``As the mother
crashes, the baby will crash, too.''
The study reviewed Norwegian records for single births to
first-time mothers from 1967 to 2003 to compare incidents of
preterm births and induced labors for women with preeclampsia and
rates of infant survival. It found that while the percentage of
induced labors before 37 weeks rose to 20 percent from 1991 to 2003
from 8 percent in 1967 to 1978, stillbirths fell to 1.3 per 1,000
babies born in the later time span from 4.2 in the earlier period,
Basso said.
8 Percent of Pregnancies
Preeclampsia affects as many as 8 percent of all pregnancies
and typically occurs after 20 weeks of gestation, although it can
occur earlier, according to the Preeclampsia Foundation, a
nonprofit research and education advocate based in Bellevue,
Washington. High blood pressure and protein in the urine are often
accompanied by swelling, sudden weight gain, headaches and changes
in vision, and can cause illness and death in the mother and the
baby.
``There's not really a science to treating preeclampsia,''
said Eleni Tsigas, chairwoman of the foundation's board. ``All
you're really doing is monitoring it because it can go from mild to
severe very quickly.''
The condition is responsible for 76,000 deaths a year, the
group said.
Medical advances, including better care of premature babies
and improved access to prenatal care, have helped push down the
overall number of infant deaths, including those related to
preeclampsia, Basso said. Early detection of the condition through
a noninvasive test, as well as improved fetal monitors, have also
helped, although there is no way to prevent it.
``Just delivering the babies isn't enough,'' Tsigas said. ``We
really need to find a way to prevent preeclampsia.''
