SIDS is a type of sudden unexpected infant death, a term that encompasses all unexpected infant deaths, both deaths from SIDS and those for which a cause is ultimately determined.1 Of the 3500 U.S. yearly cases of sudden unexpected infant death, 27% to 43% are due to SIDS.2,3 A number of other terms are used in pediatrics to refer to sudden and unexpected death. Sudden unexpected death of an infant is interchangeable with sudden unexpected infant death, and sudden death in the young (SDY) refers to such a death in any child ≤19 years old. Sudden unexplained early neonatal death is limited to infants succumbing within the first week of life and is often caused by congenital abnormalities. Sudden intrauterine unexpected death syndrome refers to stillbirths for which a postmortem exam cannot identify a cause, and sudden unexpected death in epilepsy is an unexpected death in an individual with epilepsy (excluding trauma or drowning) in which a postmortem exam does not reveal an anatomic or toxicologic cause.
