Perinatology & Child Care

Perinatologist

An obstetrical subspecialist concerned with the care of the mother and fetus at higher-than-normal risk for complications. Since the perinatal period, depending on the definition, starts at the 20th to 28th week of gestation and ends 1 to 4 weeks after birth, a perinatologist logically could be an obstetrician or pediatrician but, in practice, a perinatologist is an obstetrician. The comparable area of pediatrics is neonatology. A high-risk baby might be cared for by a perinatologist before birth and by a neonatologist after birth. The word perinatologist is a linguistic sandwich of the Greek peri meaning around or about, natal from the Latin natus meaning born and ologist from the Greek logos meaning student of.
