CHAPEL HILL, N.C., Jan. 30 -- Intracranial bleeding in newborns has been found common after a vaginal birth, although the bleeding is limited and apparently has no effect, according to researchers here.
In a study using magnetic resonance imaging, about one infant in four delivered vaginally had at least one form of intracranial hemorrhage, found John Gilmore, M.D., of the University of North Carolina School of Medicine, and colleagues.
MRI did not show signs of bleeding for babies born by caesarian delivery, they reported in the February issue of Radiology.
"Small bleeds in and around the brain are very common in infants who are born vaginally," Dr. Gilmore said. "It seems that a normal vaginal birth can cause these small bleeds."
