Abstract
This study reports the school-age developmental and health status of a preventilatory surfactant cohort. The sample consisted of 39 surviving subjects (21 experimental and 18 controls) born at 25 to 29 weeks gestation who were studied at 6 and 12 months and 5 to 7 years of age. At 6- and 12-month follow-ups, the cohort was functioning close to the population normative mean. Although cognitive and motor assessments at school age also showed no group differences, 8 of 19 (42%) in the surfactant group and 9 of 17 (53%) in the normal saline group attained a McCarthy General Cognitive Index score of < or = 84 (abnormal range). On the Connors' Parental Questionnaire, both groups scored high on the Learning Disability Subscale. The surviving cohort at 5 to 7 years had no identified long-term sequelae due to surfactant therapy, yet both groups were at risk for neurodevelopmental and educational morbidity.
