Factors associated with survival and freedom from cerebral parenchymal lesions and severe retinopathy were examined in a cohort of 250 extremely preterm infants of less than 26 weeks gestation admitted to a regional neonatal intensive care unit between 1982 and 1993. There were 99 survivors of whom 73 were free of major early morbidity.
Conclusion: Logistic regression showed that both survival and survival free from early morbidity were independently related to gestation, birth weight, birth period and antenatal steroid prophylaxis.
