Most infants born at 36 and 37 weeks' gestation are mature enough to be discharged from the hospital with the mother. But many premature infants need care in the neonatal intensive care unit (NICU). Hospital care will be needed for: 1  Underdeveloped lungs. 2  Inability to breathe continuously (apnea of prematurity) . 3  Inability to maintain body heat.
Those final weeks in the womb are crucial for healthy weight gain and for the full development of various vital organs, including the brain and lungs. This is why premature babies may have more medical problems and may require a longer hospital stay. They may also have long-term health issues, such as learning disabilities or physical disabilities. In the past, premature birth was the major cause of infant death in the United States. Today, the quality of care for newborns has improved, as have the survival rates of premature babies. Yet premature birth is still the top cause of infant death worldwide, according to the Centers for Disease Control and Prevention.
