From October, 1986 to February, 1990 eighty-five potential donors with death of the brain were examined at the Scientific Research Institute of Transplantology and Artificial Organs, USSR Ministry of Public Health. Thirty of them were used as heart donors in orthotopic transplantation of the heart; 24 (80%) were males and 6 (20%) females. The cause of death of the brain was craniocerebral trauma in 13, brain tumor in 9, hemorrhage into the brain tissue in 7 cases, and gunshot injury to the skull with damage to the brain in one case. In appraisal of the donors; in 8 (26.7%) cases the ECG did not differ from the initial one, in another 8 cases (26.7%) the ECG demonstrated electrolyte disorders in the form of hypokalemia , still in another 8 cases right bundle-branch block was encountered, in 2 (6.65%) the ECG showed transient form of cardiac fibrillation, in still another 2 cases I-II degree atrioventricular block was found, in one (3.3%) right and left bundle-branch block was demonstrated, and in one case the ECG showed diminished nutrition in the region of the posterior left-ventricular wall. All donors had disorders of homeostasis characteristic of patients with death of the brain, while the condition of hemodynamics conformed to these disorders. It is concluded on the basis of the obtained data that electrocardiographic monitoring is expedient and that it plays a role in complex appraisal of a potential heart donor. |
