Abstract
According to the German Medical Council guidelines, the proof of irreversible brain death can be carried out using clinical investigations alone or can necessitate the use of ancillary tests (ATs), depending on the patient age and type of brain injury. Retrospective evaluation of the diagnostics of irreversible brain death, which were carried out using ATs according to the third edition of the guidelines between January 2001 and December 2010 in Berlin, Brandenburg and Mecklenburg-Western Pomerania and were registered at the German National Foundation for Organ Transplantation. In 1401 patients (aged 0-94 years) a total of 1636 ATs were carried out. The most frequently used additional procedure for the first AT was an electroencephalogram (EEG) in 71.7 %. Confirmatory results regarding irreversibility were reported for 93.6 % of the initial ATs. Negative results of ATs were less common with primary supratentorial brain lesions (2.9 %) compared to infratentorial lesions (13.7 %), secondary hypoxic brain damage (8.1 %) and children younger than 2 years old (18.5 %). Regardless of the AT results, a return of clinical brain function was never documented. The timing, type and repetition of ATs were variable. In most cases the diagno...Continue Reading
