A neonatal intensive care unit, or NICU, is a specialized hospital unit that provides intensive medical and nursing care to newborn infants who are critically ill or at high risk because of prematurity, low birth weight, or congenital and acquired conditions. It delivers continuous monitoring and life-supporting interventions, including thermoregulation, respiratory support and ventilation, intravenous fluids and nutrition, and management of infection, alongside specialized feeding support such as the use of human milk and milk banks. The NICU cares for a range of neonatal problems, from the complications of preterm birth and difficulties with breathing and feeding to surgical and gastrointestinal conditions such as necrotizing enterocolitis, tracheoesophageal fistula, and congenital diaphragmatic hernia, and it supports infants requiring prenatal diagnosis and complex postnatal management. Care is delivered by multidisciplinary teams of neonatologists, neonatal nurses, and allied professionals using advanced technology and graded levels of support according to the infant's acuity. Important priorities include the prudent use of antimicrobials to limit resistance, the protection of nutritional integrity, and attention to developmental and family-centered care. Research relevant to the NICU spans infection control, nutrition and breastmilk handling, novel biomarkers for early diagnosis, and outcomes of high-risk newborns. By concentrating expertise and resources, the NICU aims to improve survival and long-term health for vulnerable neonates.
