    Description / Table of Contents: Summary The effect of hyperbaric oxygen on cochlear microphonics, action potential of the auditory nerve, and brain stem response damaged by short exposure to noise is varied. Of 26 guinea pigs 14 showed a positive influence as measured by amplitudes. In 12 animals oxygen had little or no effect. The reason for this could lie in the individual reaction to the anesthetic of the section of the auditory nerve tested. The reaction of postmortem cochlear microphonics after hyperbaric oxygen treatment indicates oxygen diffusion through the round window.
    Notes: Zusammenfassung Hyperbarer Sauerstoff wirkt auf die durch kurzzeitige Lärmbelästigung geschädigten Mikrophon-, Nervenaktions- und Stammhirnpotentiale unterschiedlich. Vierzehn von 26 Meerschweinchen zeigten einen positiven Effekt, — gemessen an den Amplituden. Bei 12 Tieren wirkte Sauerstoff nicht oder nur sehr gering. Die Ursache wird in individuellen Narkoseeinflüssen auf den gemessenen Hörabschnitt vermutet. Das Verhalten der postmortalen Mikrophonpotentiale nach hyperbarer Oxygenation läßt auf eine Sauerstoffdiffusion durch das runde Fenster schließen.
