A total of 823 infants born at 28 weeks' gestation or less were admitted to a regional referral unit between 1980 and 1989. Four hundred and sixty five (56.5%) survived to be discharged home. Twenty one subsequently died and two were lost to follow up. Four hundred and forty two (53.7%) were assessed for disabilities at the age of 3 years. Eighty four (19%) had major disabilities, of which 40 (9%) were severe. A further 39 (9%) had lesser disabilities. Three hundred and nineteen (63%) survivors appeared to be functioning normally. Logistic regression showed the likelihood of survival to be independently related to gestational age, birthweight ratio, and more recent year of birth, and inversely related to male sex and ultrasound evidence of cerebral haemorrhage or infarction. The likelihood of later disability in survivors was only independently related to cerebral ultrasound appearances.
1980年至1989年间,共有823名孕周28周及以下的婴儿被收治于一家区域转诊单位。其中465名(56.5%)存活至出院回家。21名随后死亡,2名失访。442名(53.7%)在3岁时接受了残疾评估。84名(19%)有严重残疾,其中40名(9%)为重度残疾。另有39名(9%)有较轻残疾。319名(63%)存活者似乎功能正常。逻辑回归分析显示,存活的可能性与孕周、出生体重比及更近的出生年份独立相关,与男性性别以及脑内出血或梗死的超声证据呈负相关。存活者日后出现残疾的可能性仅与脑部超声表现独立相关。
