Cardiorespiratory events in extremely low birth weight infants: neurodevelopmental outcome at 1 and 2 years

Objective:to examine the association between cardiorespiratory events (cre) and neurodevelopmental (nd) outcome at 8 and 20 months corrected age (ca) in a contemporary extremely low birth weight (elbw )cohort.study design:retrospective chart review of 98 elbw infants born in 2009 to 2010 who completed nd assessments at 8 and 20 months ca. neonatal, sociodemographic, cre and nd data were collected. nd outcome measures included neurologic examination and results from the bayley scales of infant and toddler development-iii. multiple regression analyses adjusted for the impact of neonatal risk factors on nd outcome.result:after adjusting for neonatal and social variables, greater frequency of cre was related to worse language scores at 8 months, while cre of greater severity were related to worse language at 20 months ca.conclusion:cre in elbw infants have impact on language development in the first two years of life.
