鉀對健康人吞嚥表現的影響

// Effects of Potassium on Swallowing Performance in Healthy Humans

本研究探討氯化鉀（KCl）對自主外吞嚥啟動的影響｜利用不同速率注入溶液至志願者下咽部，並以肌電圖檢測咽肌活動｜結果顯示高速率注入時，KCl能顯著促進吞嚥，顯示其作用依賴注入速率且涉及多重感覺機制，對吞嚥障礙治療具啟示意義。

// This study investigated how potassium chloride (KCl) influences involuntary swallowing initiation by infusing solutions into the hypopharynx of volunteers at different rates. Using electromyography to measure swallowing muscle activity, results showed that at a low infusion rate, KCl did not significantly enhance swallowing beyond water, but at a higher rate, KCl facilitated swallowing more than water or saline. The findings suggest that KCl's effect on swallowing depends on infusion rate and possibly involves multiple sensory inputs. Thus, higher KCl infusion rates can enhance swallowing initiation through combined sensory mechanisms.
