Brain death. Cerebral appearance of inhaled hydrogen in the diagnosis of cerebral circulatory arrest

Abstract

121 qualitative registrations of the cerebral appearance of inhaled hydrogen were performed in 21 patients with fatal intracranial disease approaching brain death. A platinum electrode, designed for the present purpose and placed in the cerebral cortex was used for the measurements. The aim was to determine the time of cerebral circulatory arrest, not to measure tissue perfusion quantitatively. The system was found inexpensive, electrotechnically simple, safe to the patient and registrations could be repeated with short intervals. Good correlation was found with the angiographic demonstration of circulatory arrest in the brain. It is stressed that the method, being locally applied cannot by itself give conclusive information about global cessation of cerebral blood flow.
