[Comparison of different treatments of acute acoustic trauma]

Comparison between different treatments of acute acoustic trauma. The acute acoustic trauma, induced tinnitus, hearing loss and an fickle otalgia, is a Permanent or a Temporary Threshold Shift. In a retrospect study of 184 patients, or 313 cases, the target of this research was to determinate a possible level of blood dilution resulted during normovolemic hemodilution, and an optimal therapeutic group. In fact, just the dilay of a starting treatment between 0 and 3 days permitted to obtain this group on qualitatives and quantitative criteria; efficiency of the treatment is better than the damages are important. We observed an important post normovolemic hemodilution effect on audition recovery and tinnitus evolution. In return, an optimal hematocrite value hadn't been found between 29 and 35%.
