Objectives/HypothesisTo determine the relationship between body mass index沿着着with other anthropomorphic variables as they relate to tracheal airway dimensions.Study DesignRetrospective cases series.MethodsThis is a radiographic study of 123 continuous hospitalized patients undergoing tracheotomy over a 4-year period（2007-2011）.我们测量了轴向计算机断层扫描成像的气道尺寸，并与身高、体重、体重指数、性别和年龄进行了比较。在第一个气管环水平进行测量，包括前后长度、宽度和计算面积。我们预计较高的体重指数不是一个很好的预测较大的气道dimensions.ResultsThe线性回归模型显示，体重指数显着负相关的气管宽度后，控制性别和年龄（P= 0.0389）。体重指数每增加1 kg/m（2），气管宽度减少0.05 mm。气道面积有随体重指数增加而减小的趋势。我们的研究表明，随着体重指数的增加，气道有变小的趋势。具体而言，随着体重指数的增加，气管宽度似乎减少。这些信息应该有助于医疗专业人员避免使用更大的管来固定肥胖患者的气道。希望这将导致对该领域的进一步研究，并可能在肥胖已成为流行病的社会中预防未来的气道损伤。证据等级4喉镜，125：1093-1097，2015
Objectives/HypothesisTo determine the relationship between body mass index along with other anthropomorphic variables as they relate to tracheal airway dimensions.Study DesignRetrospective case series.MethodsThis was a radiographic study of 123 consecutive hospitalized patients undergoing tracheotomy over a 4-year period (2007-2011). We measured airway dimensions in axial computed tomography imaging and made comparisons with height, weight, body mass index, gender, and age. Measurements were taken at the first tracheal ring level including anterior-posterior length, width, and calculated area. We expected higher body mass index not to be a good predictor of larger airway dimensions.ResultsThe linear regression model showed body mass index was significantly inversely related to tracheal width after controlling for gender and age (P=.0389). For every 1 kg/m(2) increase in body mass index, the tracheal width decreased by 0.05 mm. There was a trend for airway area to diminish with increasing body mass index.ConclusionsThese results are consistent with the hypothesis that obese patients do not have larger airways. Our study indicated a trend toward smaller airways as body mass index increased. Specifically, as body mass index increases, tracheal width appears to decrease. This information should help medical professionals avoid the tendency to use a larger tube to secure the airway of an obese patient. Hopefully, this will result in further research into the field and may prevent future airway injuries in a society where obesity has become epidemic.Level of Evidence4 Laryngoscope, 125:1093-1097, 2015
