[Irreversible loss of brain function-Part 1: pitfalls in clinical diagnosis]

Abstract

A significant change in the fourth update of the German guidelines on determining brain death is that it includes an explicit profile of requirements on physicians involved in ILBF diagnosis. These requisite qualification criteria have also been formulated due to the fact that, in many hospitals, ILBF diagnosis is only rarely carried out and, as a result, uncertainty frequently arises. Typical difficulties emerge at all stages of ILBF diagnosis, and numerous relevant pitfalls arise that need to be taken into consideration and which might also be relevant in the selection of the method(s) to detect irreversibility. The approaches presented here are suited to achieving a valid result in the evaluation of equivocal ILBF.
