Factors affecting the survival of 136 consecutive live-born infants delivered at 24 to 28 weeks' gestation during a 4-year period were analyzed. After careful assessment of gestational age, perinatal care for the fetus of at least 26 weeks' gestation was aggressive. Survival at 26 weeks was 45% and at 28 weeks, 92%. Multivariate analysis showed that the set of variables that best predicts neonatal outcome is gestational age, antepartum glucocorticoid administration, and resuscitation at birth.
分析了4年期间136例孕24至28周连续活产婴儿的存活影响因素。在仔细评估孕周后，对孕周至少26周的胎儿进行积极的围产期护理。孕26周时的存活率为45%，孕28周时为92%。多变量分析表明，最能预测新生儿结局的变量组是孕周、产前糖皮质激素给药和出生时的复苏。
