We reviewed outcomes in 65 infants with extremely low birth weight who were treated at our perinatal center from January 1981 through December 1989. Included in the study were infants whose gestational age was less than or equal to 26 weeks and whose birth weight was less than or equal to 750 grams. The outcomes were compared for three periods, 1981-83 (n = 16), 1984-86 (n = 20) and 1987-89 (n = 29). There was no significant difference in survival rate during the study period (19 vs 25 vs 31%). However, significantly more children now survive the first 24 hours of life.
我们回顾了1981年1月至1989年12月在我们围产期中心接受治疗的65例极低出生体重儿的治疗结果。纳入研究的婴儿胎龄小于或等于26周，出生体重小于或等于750克。对三个时间段（1981 - 1983年，n = 16；1984 - 1986年，n = 20；1987 - 1989年，n = 29）的治疗结果进行了比较。研究期间的存活率没有显著差异（分别为19%、25%和31%）。然而，现在有更多的儿童在出生后的头24小时内存活下来。
