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.

According to a substantial literature, passive smoking by children is associated with an increased incidence of lower respiratory illness and diminished pulmonary function. The relationship between passive smoking and childhood asthma, however, is not clear. Data from the Child Health Supplement to the 1981 National Health Interview Survey were analyzed with information about 4331 children aged 0 to 5 years to study the relationship between maternal smoking and (1) the prevalence of childhood asthma, (1) the likelihood of taking asthma medication, (3) the age of onset of children's asthma, and (4) the number of hospitalizations among children with and without asthma. ⋯ Maternal smoking is also associated with increased numbers of hospitalizations by its association with an increased risk of asthma as well as by contributing to hospitalizations independently of a child having asthma. Among children with asthma, however, maternal smoking is not associated with increased numbers of hospitalizations. It was concluded that maternal smoking is associated with higher rates of asthma, an increased likelihood of using asthma medications, and an earlier onset of the disease.(ABSTRACT TRUNCATED AT 250 WORDS)

The axillary vein was evaluated as an alternative access site for central venous catheterization in critically ill infants and children. Children were placed in the Trendelenberg position (when possible) with arm abducted 100 to 130 degrees. The vein was entered parallel and inferior to the artery. ⋯ No complication contributed to a patient mortality. Success and complication rates were comparable with those in jugular catheterization studies in children. The axillary approach is an acceptable route for central venous catheterization in critically ill infants and children.
