Study redefines the 'Optimal time for delivery'
The number of fetal deaths that could be avoided by delivery is greater than the number of neonatal deaths that would be anticipated by delivery around 37 to 38 weeks' gestation, according to research published in the March issue of the American Journal of Obstetrics & Gynecology.

(HealthDay)—The number of fetal deaths that could be avoided by delivery is greater than the number of neonatal deaths that would be anticipated by delivery around 37 to 38 weeks' gestation, according to research published in the March issue of the American Journal of Obstetrics & Gynecology.

Using data from the National Center for Health Statistics, Alicia Mandujano, M.D., of the MetroHealth Medical Center/Case Western Reserve University in Cleveland, and colleagues examined the optimal gestational age for by comparing the risk of for those fetuses remaining undelivered with the rate of neonatal death for each week of gestation.

According to the researchers, the risk of fetal death declined between 34 and 40 weeks' gestation, but then increased at term. The fetal death risk of those remaining undelivered was higher for high-risk pregnancies than for low-risk pregnancies. By 37 to 38 weeks' gestation, the number of exceeded the number of .

"The data reported herein suggest that the 'optimal time for delivery' is not necessarily the same for everyone, and, as is often the case in the practice of medicine, providers should individualize their approach for each patient," the authors write.
