What does neonatal mean?
Neonatal is an adjective meaning relating to newborn babies or to the period immediately following birth. In medicine, it usually refers to the first four weeks of life, a time when infants can be particularly vulnerable to complications and when specialized hospital care may be needed. The word is used with expressions such as neonatal care, neonatal intensive care, neonatal mortality, and neonatal conditions. Although “newborn” can describe an individual baby, “neonatal” more often describes a category of care, a medical condition, a stage of development, or an outcome involving infants. Its precise medical use has made it especially important in paediatrics, public health, and discussions of infant health. The term is used in both British and American English and is recognized as a specialized but increasingly familiar vocabulary word.
