Correlação entre a classificação de Friedman e Índice de Apneia-Hipopneia em portadores de Síndrome da Apneia e Hipopneia Obstrutiva do Sono

Abstract

OSAHS is an important disease in current medical settings because of its association with chronic cardiovascular diseases and socioeconomic impacts.Aims: to establish the correlation between the Friedman Classification and the OSAHS severity through the Apnea-Hypopnea Index) in patients with OSAHS for assessment and surgery purposes. Materials and Methods:Cross-sectional study. We evaluated and classified 143 patients, using the Epworth's and Friedman's scale and OSAHS severity according to the AHI.Results: 112 patients were submitted to polysomnography. We compared the Friedman Score and the IAH. The variables were associated with p<0.05. We found that patients with light OSAHS, tended to have a lower Friedman classification (better surgical result). By the same token, patients with moderate to severe OSAHS had a greater prevalence of Friedman's score of III and IV; p< 0.05 (lower success rates from uvulopalatopharyngoplasty). Conclusion:We conclude that the Friedman's classification correlates with OSAHS severity -the higher the Friedman's score, the more severe is the OSAHS. Braz J Otorhinolaryngol. 2010;76(5):557-60.
