PY - 2022 T2 - Current Diagnosis & Treatment: Pediatrics, 26e AB - The newborn period is defined as the first 28 days of life. In practice, however, sick or very immature infants may require neonatal care for many months. There are four levels of newborn care. Level 1 refers to basic care of well newborns, neonatal resuscitation, and stabilization prior to transport. Level 2 refers to specialty neonatal care of premature infants greater than 1500 g or more than 32 weeks’ gestation. Level 3 is subspecialty care of higher complexity neonates without limitations based on newborn size and gestational age. Level 4 includes availability of specialized pediatric surgery, cardiac surgery, and extracorporeal membrane oxygenation (ECMO). Level 4 care is often part of a perinatal center offering critical care and transport to the high-risk mother and fetus as well as the newborn infant.
