A neonatal intensive care unit (NICU), a.k.a. an intensive care nursery (ICN), is an intensive care unit (ICU) specializing in the care of ill or premature newborn infants. The NICU is divided into several areas, including a critical care area for babies who require close monitoring and intervention, an intermediate care area for infants who are stable but still require specialized care, and a step down unit where babies who are ready to leave the hospital can receive additional care before being discharged. Neonatal refers to the first 28 days of life. Neonatal care, including specialized nurseries or intensive care, has been around since the 1960s. The first American newborn intensive care unit, designed by Louis Gluck, was opened in October 1960 at Yale New Haven Hospital. An NICU is typically directed by one or more neonatologists and staffed by resident physicians, nurses, nurse practitioners, pharmacists, physician assistants, respiratory therapists, and dietitians. Many other ancillary disciplines and specialists are available at larger units. The term neonatal comes from neo, 'new', and natal, 'pertaining to birth or origin'.
Roles and tasks A neonatal nurse practitioner is a registered nurse who has been specially trained to help with the care of a newborn. A dietician helps ensure the baby gets enough nutrients for healthy growth. A respiratory therapist helps with managing oxygen and breathing machines. A physical or occupational therapist watches the baby's development.
Nursing and neonatal populations
Healthcare institutions have varying entry-level requirements for neonatal nurses. Neonatal nurses are registered nurses (RNs), and therefore must have an Associate of Science in Nursing (ASN) or Bachelor of Science in Nursing (BSN) degree. Some countries or institutions may also require a midwifery qualification. Some institutions may accept newly graduated RNs having passed the NCLEX exam; others may require additional experience working in adult-health or medical/surgical nursing. Some countries offer postgraduate degrees in neonatal nursing, such as the Master of Science in Nursing (MSN) and various doctorates. A nurse practitioner may be required to hold a postgraduate degree. The National Association of Neonatal Nurses recommends two years' experience working in a NICU before taking graduate classes. As with any registered nurse, local licensing or certifying bodies, as well as employers, may set requirements for continuing education. There are no mandated requirements to becoming an RN in an NICU, although neonatal nurses must have certification as a neonatal resuscitation provider. Some units prefer new graduates who do not have experience in other units, so they may be trained in the specialty exclusively, while others prefer nurses with more experience. Intensive-care nurses undergo intensive didactic and clinical orientation in addition to their general nursing knowledge in order to provide highly specialized care for critical patients. Their competencies include the administration of high-risk medications, management of high-acuity patients requiring ventilator support, surgical care, resuscitation, advanced interventions such as extracorporeal membrane oxygenation or hypothermia therapy for neonatal encephalopathy procedures, as well as chronic-care management or lower acuity cares associated with premature infants such as feeding intolerance, phototherapy, or administering antibiotics. NICU RNs undergo annual skills tests and are subject to additional training to maintain contemporary practice.
History The problem of premature and congenitally ill infants is not a new one. As early as the 17th and 18th centuries, there were scholarly papers published that attempted to share knowledge of interventions. It was not until 1922, however, that hospitals started grouping the newborn infants into one area, now called the neonatal intensive care unit (NICU).
Before the Industrial Revolution, premature and ill infants were born and cared for at home and either lived or died without medical intervention. In the mid-nineteenth century, the infant incubator was first developed, based on the incubators used for chicken eggs. Stephane Tarnier is generally considered to be the father of the incubator (or isolette as it is now known), having developed it in 1880 to attempt to keep premature infants in a Paris maternity ward warm. Other methods had been used before, but this was the first closed model; in addition, he helped convince other physicians that the treatment helped premature infants. France became a forerunner in assisting premature infants, in part due to its concerns about a falling birth rate. After Tarnier retired, Pierre Budin, followed in his footsteps, noting the limitations of infants in incubators and the importance of breastmilk and the mother's attachment to the child. Budin is known as the father of modern perinatology, and his seminal work The Nursling (Le Nourisson in French) became the first major publication to deal with the care of the neonate. The incubator was improved in 1890 in Marseilles by Alexandre Lion, who founded in 1891 the Œuvre Maternelle des Couveuses d'Enfants in Nice and in January 1896 in Paris. Another factor that contributed to the development of modern neonatology was Martin Couney and his permanent installment of premature babies in incubators at Coney Island. A more controversial figure, he studied under Budin and brought attention to premature babies and their plight through his display of infants as sideshow attractions at Coney Island and the World's Fair in New York and Chicago in 1933 and 1939, respectively. Infants had also previously been displayed in incubators at the 1897, 1898, 1901, and 1904 World Fairs.
