Neonatology is a subspecialty of paediatrics that comprises of the restorative care of newborns, particularly the premature or sick baby. It's a hospital-based forte generally practised in NICUs - neonatal concentrated care units. Infants are mostly the patients of neonatologists require special medical attention because of ill or prematurity, low birth weight, intrauterine growth retardation, birth asphyxia, sepsis and congenital malformations. Neonatology has drastically developed since its beginnings in the late 1960s, and neonatologists have turned into an integral part of the obstetric-pediatric team at significant medical centres all through the world. Additionally, being looked after by the doctors who have some expertise in neonatology, some neonatal newborn babies, specifically those who are critically premature or ill, are cared by nurse practitioners. For infection control, if an infant has gone home and then gotten sick and brought back to the hospital, then the infant will probably be admitted to a paediatric intensive care unit or paediatric ward rather than the NICU.
