Randomized Controlled Trial Multicenter Study Clinical Trial
Phototherapy for neonatal hyperbilirubinemia: six-year follow-up of the National Institute of Child Health and Human Development clinical trial.
The National Institute of Child Health and Human Development Randomized, Controlled Trial of Phototherapy for Neonatal Hyperbilirubinemia was conducted to determine whether phototherapy used to control serum bilirubin is safe and is as effective in preventing brain injury as exchange transfusion. The study, conducted at six neonatal care centers, randomly assigned 1339 newborn infants to phototherapy or control groups by the following subgroups: (1) birth weight less than 2000 g; (2) birth weight 2000 to 2499 g and bilirubin level greater than 171 mumol/L (10 mg/dL); or (3) birth weight greater than or equal to 2500 g and bilirubin level greater than 222 mumol/L (13 mg/dL). Phototherapy was administered for 96 hours, and exchange transfusion was used to control hyperbilirubinemia at the same predetermined levels in both groups. ⋯ The phototherapy and control groups had similar rates of cerebral palsy (5.8% vs 5.9%), other motor abnormalities including clumsiness and hypotonia (11.1% vs 11.4%), and sensorineural hearing loss (1.8% vs 1.9%). The Wechsler Intelligence Scale for Children-Revised scores overall were not significantly different for the two groups (Verbal, 96.8 vs 94.8; Performance, 95.8 vs 95.1 for phototherapy and control groups, respectively). Phototherapy effectively controlled neonatal hyperbilirubinemia without evidence of adverse outcome at 6 years of age and was at least as effective as management with exchange transfusion alone.
