Emprego da determinação de monóxido de carbono no ar exalado para a detecção do consumo de tabaco

Abstract: Introdução: O tabagismo é o principal fator de risco prevenível de morbidade e mortalidade em países desenvolvidos e está em ascensão nos países em desenvolvimento. Apesar deste fato, e do maior conhecimento sobre seus efeitos, a prevalência de tabagistas continua elevada. Com o objetivo de comparar o valor de monóxido de carbono no ar exalado (COex) entre indivíduos fumantes e não fumantes, avaliar fatores que influenciam estes valores entre os que fumam e também avaliar a possível influência do tabagismo pas… Show more

“…Nine patients were excluded: 2 patients on the otorhinolaryngology ward for undergoing tracheostomy; 1 patient on the clinical neurology ward and 1 patient on the neurosurgery ward, both due to a drop in the level of consciousness; 1 patient on the pulmonology ward for being submitted to invasive mechanical ventilation; 2 patients on the general recent smoking, we used a cut-off point of 6 ppm, as suggested in a study in which this value was found to have a sensitivity of 77% and a specificity of 96%. (13) It is known that environmental pollution, passive smoking and inflammatory pulmonary diseases such as asthma, bronchiectasis and primary ciliary dyskinesia can influence the results obtained, reaching values near 7 ppm. In the sample evaluated in this study, the influences of environmental pollution and passive smoking were excluded, since the patients had been hospitalized for more than 8 h. None of the interviewees reported having a history of any of the pulmonary diseases mentioned above.…”

“…A COex value above 6 ppm was considered a significant indicator of recent smoking. (13,14) Patients hospitalized for less than 8 h were excluded from the study due to possible interference with the results of the COex measurement.…”

“…These results are consistent with data in the literature. In one study, (7) the authors observed that the measurement of exhaled CO, which is a noninvasive, low-cost method, proved quite useful in evaluating the smoking habit.…”

“…A aplicação da técnica foi padronizada conforme a descrição: o indivíduo foi orientado a inspirar profundamente e então permanecer em apneia por 20 segundos. Em seguida era acoplado o aparelho (Micro Medical Ltda., Rochester, Reino Unido) na boca do indivíduo e o mesmo era orientado a realizar uma expiração completa de maneira lenta e suave [22].…”
