Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults aged 18 and older who are undergoing planned withdrawal of life-sustaining measures and are expected to die within 24 hours.

Probably not a fit

Patients who are already declared brain dead or those with conditions that prevent neurologic monitoring will not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to investigate the timing of brain function cessation in relation to heart function cessation by using electroencephalography (EEG) in patients who are undergoing withdrawal of life-sustaining measures in an intensive care unit. It seeks to provide evidence regarding the neurologic determination of death, particularly in the context of organ donation after circulatory determination of death. By monitoring electrical brain activity, the study will clarify the relationship between brain and heart activity during the dying process, addressing concerns about the current practices in organ donation. The findings could enhance the understanding of death determination and improve trust in the organ donation process.

Why it matters

Potential benefit: If successful, this study could provide critical insights that enhance the ethical framework and trust surrounding organ donation practices.

How similar studies have gone: While the approach of monitoring brain activity during the dying process is novel, similar studies have not been widely conducted, making this an important and potentially groundbreaking investigation.
