气管切开术与吞咽功能障碍之间的关系早已被认识到，这种功能障碍通常表现为误吸，这可能是一些病因因素所致。声门关闭的中断以前已经被证实与留置气管切开管的存在有关。堵塞或拔除气管造口管，或使用呼气阀，已被证明可以减少吸入和改善吞咽功能。吞咽时通过留置气管切开管声门下压力的测量显示，压力峰值出现在吞咽和喉部抬高的同时。本报告将回顾支持声门下压力升高在吞咽效率中的作用的证据。将审查目前的调查活动，并提出新的研究领域。
The relationship between tracheostomy and swallowing dysfunction has been long recognized, Often this dysfunction is manifested by aspiration, for which a number of etiologic factors may be responsible. Disruption of glottic closure has been previously demonstrated in association with the presence of an indwelling tracheostomy tube. The plugging or removal of the tracheostomy tube, or the use of an expiratory air valve, has been demonstrated to decrease aspiration and improve swallowing function. Measurement of subglottic pressure through an indwelling tracheostomy tube during swallowing demonstrated pressure peaks occurring concomitant with swallowing and laryngeal elevation. This presentation will review the evidence supporting the role of subglottic pressure rise in swallowing efficiency. Current investigational activity will be reviewed, and new areas for study will be suggested.
