[Artificial arterial hypotension during surgical treatment of intracranial aneurysms].
In studying the content of lactic and pyruvic acids in the cerebrospinal fluid of 31 patients during operation for intracranial aneurysms under halothane anesthesia, the authors established that the performance of these operations under protection of deep (40 mm Hg) and prolonged (up to 2 hrs 25 min) artificial arterial hypotension in an uncomplicated course of the surgical intervention was not attended with hypoxic damage of the brain. The danger of hypoxia developing became greater when acute disturbances of blood flow in the cerebral arteries (clipping of a vessel, spasm) occurred in the period of hypotension.
