Uniforme bilirubinegrenzen voor de behandeling van icterische premature neonaten

Objective

To compare the guidelines of the 10 Dutch neonatal intensive care units (NICUs) for the treatment of preterm infants with hyperbilirubinemia, in order to develop uniform threshold levels for the total serum concentration of bilirubin (TSB) above which treatment with phototherapy or exchange transfusion is indicated.

Design

Survey.

Methods

Guidelines for hyperbilirubinemia in preterm infants (gestational age

Results

All 10 NICUs used intervention criteria based on TSB. 9 NICUs used TSB thresholds based on birth weight (1 used gestational age) with 2, 3 or 5 categories. 6 NICUs used age-specific TSB thresholds and 4 NICUs used a constant TSB threshold. The maximum range in TSB thresholds was 170 µmol/l for phototherapy and 125 µmol/l for exchange transfusion. Acidosis, sepsis, asphyxia, active haemolysis and intraventricular haemorrhage were the risk factors most frequently used. During a consensus meeting with representatives of the 10 NICUs, a guideline was agreed upon that will now be used for all neonates with a gestational age

Conclusion

There was considerable variation in the TSB thresholds used to date by the 10 NICUs. Now in the Netherlands, in addition to guideline ‘Hyperbilirubinemia’ for children with a gestational age ≥ 35 weeks, ‘uniform yellow thresholds’ shall be used for jaundiced preterm infants with a gestational age
