title: [Carbogen combined with drugs in the treatment of sudden deafness].
abstract: OBJECTIVE
  To analyze the clinical efficiency and study the possible mechanism of the carbogen combined with drugs in the treatment of sudden deafness.
  
  
  METHODS
  Fifty-two patients with sudden deafness were divided into two groups: Twenty-six cases received carbogen (5% CO2 - 95% O2) combined with drug therapeutics of a course of intravenous administration of dexamethasone, vitaminB, low molecular dextran, salviae miltiorrhizae, and intake vitaminC, vitaminE, et al and the other 26 cases received the drugs only. The clinical effects were compared.
  
  
  RESULTS
  The total effective rate was 76.92% in the carbogen group and 50.00% in the control group. The difference was significant between the two groups. The recovery time in the carbogen group was 3-14 days while in the control group was 6-23 days.
  
  
  CONCLUSIONS
  The efficiency of carbogen ombined with drugs is superior to drug therapeutics in the treatment of sudden deafness.
