本研究的目的是利用荧光透视研究气管切开插管阻塞对抽吸的影响。纳入了20例连续气管切开患者，这些患者被转诊接受改良钡剂吞咽。选择标准是在改良吞钡手术期间能够耐受气管切开术管闭塞，除气管切开术外未进行上呼吸消化道手术，以及无口咽癌或卒中病史。3名独立评审员对存在或不存在愿望的评级100%一致。结果发现，气管切开插管的堵塞状态并不影响误吸的发生率。9/10例（90%）出现误吸的受试者年龄超过65岁（X=72岁2个月）。未观察到推注浓度、气管切开插管类型或有/无鼻胃管和抽吸评级的趋势。
The purpose of the present study was to investigate the effect of occlusion of a tracheotomy tube on aspiration utilizing fluoroscopy. Twenty consecutive tracheotomized patients referred for a modified barium swallow were included. Selection criteria were ability to tolerate tracheotomy tube occlusion during the modified barium swallow procedure, no surgery of the upper aerodigestive tract except tracheotomy, and no history of oropharyngeal cancer or stroke. These was 100% agreement among 3 independent reviewers on ratings of the presence or absence of aspiration. It was found that the occlusion status of the tracheotomy tube did not influence the prevalence of aspiration. Nine of 10 (90%) subjects who exhibited aspiration were over 65 years of age ( X=72 years 2 months). No trends were observed for bolus consistency, type of tracheotomy tube, or presence/absence of a nasogastric tube and ratings of aspiration.
