This is a subspecialty of obstetrics and neonatology concerned with the care of the mother and fetus when there are increased risks of complications. Definitions vary, but the perinatal period begins approximately after 25th week of pregnancy and ends in the first month after birth.
A high-risk baby might be cared for by a perinatologist before and during birth, and by a neonatologist after birth, although at the time of delivery, both specialists are likely to be in attendance.
A resource for perinatologists, referring physicians, and genetic counselors. Includes links to journals and research groups, as well as information on evidence based medicine and continuing education.
