What Is a Neonatal Intensive Care Unit?
A Neonatal Intensive Care Unit (NICU) is a special area of the hospital that is devoted to the care of critically ill babies. Typically a NICU is completely separated from the nursery for healthy newborns, and may not even be in the same building (the nursery is always located near the rooms for the mothers). The staff for the NICU and the staff for the newborn nursery are completely separate as well.
In most hospitals, babies are only admitted to the NICU directly from the delivery room, the newborn nursery, or from another hospital's NICU or nursery. For reasons of infection control, if a baby has gone home and then gotten sick and come back to the hospital, the baby will probably be admitted to a pediatric ward or pediatric intensive care unit rather than the NICU. Of course, exceptions can be made if the baby has a problem that definitely requires the constant attention of a neonatologist.
Babies usually stay in the NICU until they are ready to go home, even if that takes several months. This is much different than an adult or pediatric intensive care unit, where the patient will leave the unit as soon as they are stable and do not need help with their breathing and constant monitoring. For this reason, NICUs are often divided by walls or partitions into several distinct regions: a true "intensive care" area where the nurses and doctors spend most of their time at the babies' bedsides, an "intermediate care" area for babies that are still on IVs or extra oxygen, and a quieter area for the "growers."
