Objective . To evaluate a simple, relatively inexpensive method using the fluid bed to provide high-intensity double-surface (HIDS) phototherapy and to confirm that the method described is more effective than conventional phototherapy (CPT) in the treatment of neonatal hyperbilirubinemia.Design . Prospective controlled study.Method . HIDS phototherapy (26 to 30 μW/cm2 per nanometer) on the fluid bed (n = 22) versus conventional (7 to 10 μW/cm2 per nanometer) phototherapy (n = 28) was used to treat neonates weighing more than 1500 g with hyperbilirubinemia.Results . After 24 hours of therapy, the bilirubin in the group receiving HIDS phototherapy was significantly lower. The mean rate of fall of bilirubin was 5.34 μmol/L per hour in the group receiving HIDS phototherapy versus 0.7 μmol/L per hour in the group receiving CPT. HIDS phototherapy on a fluid bed was well tolerated.Conclusion . HIDS phototherapy on the fluid bed is significantly more effective in reducing bilirubin than CPT. It can be easily and economically provided using equipment currently available in most neonatal units.
