Therapeutic approaches to neonatal jaundice: an international survey.

Jaundice is one of the most common clinical phenomena in the neonatal period and a frequent indication for treatment with phototherapy, exchange transfusion, or drugs. The present study documents the variability in approaches to the treatment of this condition. A mail questionnaire was sent to neonatal units worldwide. One hundred and eight answers (49% response rate) were received from Europe (n = 72), North America (n = 28), Africa (n = 7), and Asia (n = 1). The neonatal intensive care units represented by the respondents had 31 +/- 18 beds [mean +/- SD], and 638 +/- 519 admissions per year. All units offered phototherapy, 106/108 performed exchange transfusion, while 44/108 used some form of drug therapy. There was considerable variability among the units in their approaches to the jaundiced neonate. This applied to all aspects of care, including type of phototherapy lights used, practical implementation of phototherapy, use of fluid supplementation, and use of prophylactic phototherapy. The majority used written protocols for investigation and treatment of neonatal jaundice and would let their decision on whether to treat be influenced by the infant's clinical state. There was great variability between units in the level of serum bilirubin that would trigger therapy. This applied across weight groups and to phototherapy as well as exchange transfusion. The significant heterogeneity in our approach to the treatment of jaundiced neonates suggests that our understanding of the biology of neonatal jaundice is inadequate and that further research will be necessary in order to provide a more solid biological foundation for therapy.
