Survival rates for very early preterm infants have improved slightly, according to a study published in the New England Journal of Medicine on Wednesday. Those who survive are also somewhat less likely to suffer from neurodevelopmental impairments, the study found.
Researchers gathered survival and neurodevelopmental impairment data for 4,000 extremely premature infants by analyzing records from a National Institutes of Health research network. The infants were born between 22 and 24 weeks of gestation, rather than after a normal 40-week pregnancy.
