OBJECTIVE: To review and revise the 1987 pediatric brain death guidelines. METHODS: Relevant literature was reviewed. Recommendations were developed using the GRADE system. CONCLUSIONS AND RECOMMENDATIONS: (1) Determination of brain death in term newborns, infants and children is a clinical diagnosis based on the absence of neurologic function with a known irreversible cause of coma. Because of insufficient data in the literature, recommendations for preterm infants less than 37 weeks gestational age are not included in this guideline.
