What is the chance of survival for a premature infant?
The survival of premature infants is determined by gestational age at delivery and birth weight. Infants born after 28 weeks gestation and 1,000 grams, or 3 pounds 3 ounces (454 grams equals 1 pound), have more than a 90% chance of survival. The rate of survival at 27 weeks and 900 grams is 80% to 85%, at 26 weeks and 800 grams is 75% to 80%, and at 25 weeks and 700 grams is 60%. Rates of survival drop off rapidly at less than 25 weeks, and they vary quite a bit among different nurseries. The long-term outcome also is dependent on gestational age and birth weight. For babies of 26 to 32 weeks gestation, the rate of severe neurodevelopmental problems among survivors is about 10%; at 23 to 26 weeks, the rate increases gradually to 25% of survivors. Other long-term complications, including lung problems, vision disturbances, and hearing loss, are more common in babies of lower gestational age at birth. top What is the delivery room management of the premature infant?
