TABLE 4.
NRP permissibility under variable death determination frameworks
| Death in DCDD based on | Criteria met under current DCDD protocols | Criteria met under current DCDD-NRP protocols |
|---|---|---|
| Cessation of circulation | ||
| Permanent | Yes | No |
| Irreversible | No | No |
| Cessation of intracranial circulation | ||
| Permanent | Yes | Yesa |
| Irreversible | No | No |
| Cessation of brain function | ||
| Permanent | Yes | Yesa |
| Irreversible | No | Nob |
a
Under condition that brain function has ceased at the time NRP is initiated and that surgical safeguards are effective.
b
Could be permissible provided brain function is irreversibly lost, but not permissible under current protocols because NRP is initiated prior.
DCDD, donation after circulatory determination of death; NRP, normothermic regional perfusion.
