Neonatal and follow-up data of infants from the special care nursery whose birth weights were < 750 g, born between 1980 and 1990, were reviewed. There was a 20% relative improvement in the odds of surviving the neonatal period, a 16% improvement in the odds of being discharged and a 19% improvement in the odds of surviving until 2 years of age with each consecutive year. Home oxygen use increased significantly over the study period. The neurodevelopmental outcomes of infants were similar over the 11-year period, with 53% being classified as neurologically normal, with a mean developmental index of 83 at 1 to 2 years of age. We conclude that there has been an improved survival of infants with birth weights < 750 g in our institution, and that the overall incidence of serious neurodevelopmental deficits among survivors has remained stable.
对1980年至1990年间出生体重小于750克的特殊护理病房婴儿的新生儿期及随访数据进行了回顾。每连续一年，新生儿期存活几率相对提高20%，出院几率提高16%，存活至2岁的几率提高19%。在研究期间，家庭用氧显著增加。在这11年期间，婴儿的神经发育结果相似，53%被归类为神经学正常，1至2岁时平均发育指数为83。我们得出结论，在我们机构中，出生体重小于750克的婴儿存活率有所提高，幸存者中严重神经发育缺陷的总体发生率保持稳定。
