Perinatal mortality, according to the International Statistical Classification of Diseases and Related Health Problems (ICD-10), includes death of the fetus any time after 22 weeks' gestation, stillbirth, and death of infants born alive who die during the first week of life. There is some debate about the definition of fetal viability. Advances in medical care of very immature infants have led some perinatologists to propose an earlier beginning of the perinatal period. Others assert that extremely immature fetuses have imperfectly formed brains and, although technically alive, they are likely to be severely brain damaged.
