Review Meta Analysis
Ancillary investigations for death determination in infants and children: a systematic review and meta-analysis.
We performed a systematic review and meta-analysis to determine the diagnostic test accuracy of ancillary investigations for declaration of death by neurologic criteria (DNC) in infants and children. ⋯ PROSPERO (CRD42021278788); registered 16 October 2021.

The new 2023 Canadian Brain-Based Definition of Death Clinical Practice Guideline provides a new definition of death as well as clear procedures for the determination of death (i.e., when that definition is met). Since physicians must practice in accordance with existing laws, this legal analysis describes the existing legal definitions of death in Canada and considers whether the new Guideline is consistent with those definitions. It also considers how religious freedom and equality in the Canadian Charter of Rights and Freedoms might apply to the diagnosis of brain death. ⋯ There are some differences between the wording of the new Guideline and existing legal definitions. To reduce confusion, these should be addressed through revising the legal definitions. In addition, future challenges to brain death based on the Charter of Rights and Freedoms can be anticipated. Facilities should consider and adopt policies that identify what types of accommodation of religious objection and what limits to accommodation are reasonable and well-justified.

Radionuclide perfusion studies have an established ancillary role in determination of death by neurologic criteria (DNC). While critically important, these examinations are not well understood by individuals outside of the imaging specialties. The purpose of this review is to clarify relevant concepts and nomenclature and provide a lexicon of relevant terminology of value to non-nuclear medicine practitioners who wish to better understand these examinations. ⋯ The new adult and pediatric Canadian recommendations favour use of lipophilic RPs to variable degrees, specifically 99mTc-HMPAO, the lipophilic moiety which has undergone the greatest validation. Although ancillary use of radiopharmaceuticals is quite settled in multiple DNC guidelines and best practices, several areas of further research remain open to investigation.
