The Achievement of Optimal Brain Relaxation by Hyperventilation Technics of Anesthesia

Abstract

ThE problem of the swollen or tight brain is one that has plagued the neurosurgeon since- the inception of intracranial surgery. Numerous attempts have been made to offset this condition by hypertonic solulions injected into the blood stream or by a physical approach such as hypothermia. To these technics we wish to add another technic which, in our experience, has proved quite satisfactory. We have used the technic of hyperven/Hation anesthesia since February 1958 for over 3~5 patients who have had intracranial procedures for various types of lesions. H These lesions have been located both supra- and infratentorially. The application of the technic varies in relationship to the locati<)n of the lesion for which the operation is performed.
