[Comparative evaluation of mask and intratracheal anesthesia with fluothane and nitrous oxide].
Under examination were 119 patients with mitral stenosis, stage III, in whom mask and endotracheal narcosis with 0.5, 1.0, and 1.5 volume per cent of fluothane in combination with 50% nitrogen monoxide was accomplished. As a result of studies, it was found that with the same concentrations of anesthetics in the inhaled mixture the depth of anesthesia according to EEG findings was greater in endotracheal than in mask anesthesia. Mask anesthesia was associated with more pronounced pathophysiological shifts than endotracheal one. In endotracheal narcosis with an artificial ventilation of the lung the fluothane concentration of 0.5 and 1.0 volume per cent in a combination with 50% nitrogen monoxide proved to be optimum.
