摘　　要：目的 观察测量拔管后气管导管屈角,并对屈角形成的可能相关因素进行分析。方法 全身麻醉苏醒后,收集置管时间超过50 min的数量约300条（内径型号,ID：5.5-7.5）使用后的普通PVC气管导管,冷水冲洗后放到固定支架下摄取数码照片,同时记录气管导管的型号和留置时间。使用Corel Draw 12.0对符合要求的气管导管的屈角进行测量。对屈角进行描述性统计分析,分析留置时间与气管导管屈角之间的相关性,比较不同型号气管导管的屈角。结果 气管导管屈角为86°-132°,平均（108.4±8.5）°,呈大致正态分布,气管导管留置时间与气管导管屈角之间无显著的相关性（r=-0.072,P=0.232）,而不同气管导管内径与屈角之间却表现出显著的差异性（F=167.216,P=0.000）。结论 气管导管口腔置管超过50 min后,会发生屈角变形,其屈角约为（108.4±8.5）°,其变形与气管ID有关,反映了口咽部气道解剖。Objective To measure the shaped angle of the endotracheal tube（ET） after extubation, and to analyze the related factors. Methods Three hundred oral intubated ETs（inner diameter, ID range： from 5.5 to 7.5） were collected after extubation from general anesthetized patients. After washed by cold water, the collected tubes were photographed in a fixed holder by a digital camera, and shaped angles of ETs were measured by Corel Draw 12.0. The following data were recorded of each tube： ID and intubated duration of the ETs. Shaped angles and intubated durations of ETs were statistically described, and factors which may affect ET shaped angles were also analyzed, including intubated durations and ID of ETs. Results A total of 283 photos were taken among 300 ETs, and shaped angle measured with normal distributed roughly [ranged from 86° to 132°,（108.4±8.5）° in mean]. There was no significant relationship between shaped angles and intubated duration（r=-0.072, P=0.233）. However, if grouped by ID, ETs shaped angles were differed significantly（F=44.735, P=0.000）. Conclusion After intubated orally for more than 50 min, endotracheal tubes will be shaped into a angle at（108.4 ± 8.5）° and differ from different inner diameter, which may be caused by anatomy of oropharyngeal airway.
