Mortality and Morbidity After Intrapartum Asphyxia in the preterm Fetus

This matched cohort study examined the significance of intrapartum fetal asphyxia determined biochemically in the preterm newborn in regard to outcome during the first year. Thirty preterm newborns with metabolic acidosis at delivery were compared with 60 preterm newborns, matched for birth weight, with normal blood gas measures. Deaths during the first year were reviewed. Assessment of the surviving children at 1 year corrected age included neurologic examination, Bayley scales, and Uzgiris and Hunt scale to define motor and cognitive development. Seven asphyxiated infants (23%) died during the first year compared with two nonasphyxiated infants (3%), a statistically significant difference (P
