| umls-concept:C0021294 | skos:definition | MSH: A human infant born before 37 weeks of GESTATION.,CSP: human born before the normal gestation period has elapsed, before 32 weeks of gestation.,MEDLINEPLUS: <p>A premature baby, or preemie, is born before the 37th week of pregnancy. Premature birth occurs in between 8 percent to 10 percent of all pregnancies in the United States. Because they are born too early, preemies weigh much less than full-term babies. They may have health problems because their organs did not have enough time to develop. Preemies need special medical care in a neonatal intensive care unit, or NICU. They stay there until their organ systems can work on their own. </p> | lld:umls |
