Abstract
UNLABELLED: The study concentrates on estimating the magnitude of the effect of a single risk factor, maximum total serum bilirubin (TSB) in excess of 400 micromol/l (23.4 mg/dl), on the neurodevelopmental outcome of 50, singleton, Zimbabwean neonates at 1 year of age. At 1 year corrected age the Bayley Scales of Infant Development (BSID) was administered. Two infants died and five were lost to follow up. TSB was neither associated with birth weight nor with gestational age. Of 43 infants with a TSB > 400 micromol/l (23.4 mg/dl),11(26%) scored abnormal on the BSID at 1 year of age and 5 (12%) infants developed the choreoathetoid type of cerebral palsy. CONCLUSION: Infants with bilirubin levels between 400 and 500 micromol/l (23.4 and 29.2 mg/dl) who scored abnormal or suspect on the Bayley Scales of Infant Development were preterm or had haemolytic disease. All term infants without haemolysis and with bilirubin levels between 400 and 500 micromol/l (23.4 mg/dl-29.2 mg/dl) were normal at 1 year of age.
