The Shifting Landscape of Death by Neurologic Criteria in Pediatrics: Current Controversies and Persistent Questions

Abstract

Since the concept of death by neurologic criteria (DNC) or “brain death” was articulated by the Harvard Ad Hoc Committee in 1968, efforts to establish and uphold DNC as equivalent to biologic death have been supported through federal and state legislation, professional guidelines, and hospital policies. Despite these endeavors, DNC remains controversial among bioethics scholars and clinicians and is not universally accepted by patient families and the public. In this focused review, we outline the current points of contention surrounding the diagnosis of DNC in pediatric patients. These include physiologic, legal, and philosophical inconsistencies in the definition of DNC, controversy regarding the components of the clinical exam, variability in clinical practice, and ethical concerns regarding justice and role of informed consent. By better understanding these controversies, clinicians may serve families grappling with the diagnosis of DNC more effectively, compassionately, and equitably.
