气管切开术的放置会影响吞咽功能，增加误吸的风险。最近的研究表明，由于气管切开术相关吞咽障碍的风险增加，单向说话阀放置可能有助于减少气管切开术患者的误吸。我们假设使用单向说话阀通过喉腔呼出的气流可以改善上呼吸道残留药团的清除，从而防止药团穿透和误吸。我们研究了单向说话阀放置对喉部间隙和吞咽生理学的影响。对 16 名接受气管切开术的患者进行了视频内窥镜和电视荧光镜吞咽检查，并对安装和不安装单向说话阀时的吞咽情况进行了比较。阀门 阀门的放置显着改善了喉部间隙和吞咽过程中穿透的发生率。然而，放置位置并没有显着影响咽部推注残留、喉部抬高、咽部延迟或误吸。与恢复经口喂养相关的因素是吞咽过程中足够的喉部抬高以及防止喉部穿透和误吸。我们得出的结论是，单向说话阀放置可改善喉部间隙并防止喉部穿透，从而改善口咽部吞咽生理和口腔喂养。
Tracheostomy placement affects swallowing function, increasing the risk of aspiration. Recent studies suggest that because of increased risk of swallowing disturbance associated with tracheostomy, one-way speaking valve placement may help to reduce aspiration in tracheostomized patients. We hypothesize that airflow exhaled through the laryngeal cavity using the one-way speaking valve may improve the clearance of residual bolus from the upper airway, thus preventing bolus penetration and aspiration. We studied the effects of one way speaking valve placement on laryngeal clearance and swallowing physiology. Videoendoscopic and videofluoroscopic swallowing were examined in 16 patients with the tracheostomy, and swallowing was compared with and without the one-way speaking valve in place. Valve Valve placement significantly improved laryngeal clearance and the incidence of penetration during swallowing. placement did not, however, significantly affect pharyngeal bolus residue, laryngeal elevation, pharyngeal delay or aspiration. Factors associated with the resumption of oral feedings were sufficient laryngeal elevation during swallow and the prevention of laryngeal penetration and aspiration. We concluded that one-way speaking valve placement improves laryngeal clearance and prevents laryngeal penetration, resulting in better oropharyngeal swallowing physiology and oral feeding.
