The purpose of this investigation was to determine the overall prevalence of aspiration in dysphagic individuals referred for a modified barium swallow and the underlying anatomic and/or physiologic causes. A total of 166 patients were seen during a 1-month period at 5 participating institutions. Aspiration was detected in 51.2% of the patients. The most common causes were decreased laryngeal elevation and delayed triggering of the pharyngeal motor response. A history of aspiration pneumonia was significantly associated with the presence of aspiration on modified barium swallow study. The presence of a protective cough was present in only 53% of patients who aspirated, reinforcing the need for appropriate radiologic assessment in patients with suspected dysphagia.
本研究的目的是确定因改良钡餐吞咽检查而被转诊的吞咽困难患者中误吸的总体患病率以及潜在的解剖学和/或生理学原因。在5家参与机构的1个月期间共诊治了166例患者。51.2%的患者检测到误吸。最常见的原因是喉抬高降低和咽运动反应触发延迟。误吸性肺炎病史与改良钡餐吞咽检查中误吸的存在显著相关。在误吸的患者中，只有53%的患者有保护性咳嗽，这进一步强调了对疑似吞咽困难患者进行适当放射学评估的必要性。
