Abstract

This study aimed to characterize the abnormal swallowing features observed during Videofluoroscopic Swallowing Studies (VFSS) in moderate to severe COVID-19 patients. From the JH CROWN cohort database (January 2020 to March 2022), a total of 3,660 patients with moderate to severe COVID - 19 disease requiring oxygen supplementation were identified. The study abstracted and reported VFSS referral rates and swallowing characteristics using Modified Barium Swallow Impairment Profile (MBSImP). 16% (n = 588) of patients exhibited dysphagia; only half underwent VFSS. Among those referred, 39.3% had COVID-19 severity level 7, 39% exhibited aspiration, and 30% had silent aspiration. Abnormal MBSImP scores were reported in the following components: tongue control during bolus hold (score 2/3, 40%), bolus transport and lingual motion (score 3/4, 34%), oral residue (score 2/4, 57.7%), initiation of pharyngeal swallow (score 3/4, 65.2%), laryngeal vestibular closure (score 1/2, 64.5%), and pharyngeal residue (score 2/4, 50.5%). In conclusion, this large cohort of COVID-19 patients exhibited a myriad of swallowing abnormalities in the oral and pharyngeal phases, with a notably high rate of silent aspiration. Moreover, differentiating COVID-19-induced dysphagia from post-extubation dysphagia is challenging.

COVID-19患者的异常吞咽特征。

本研究旨在描述中重度COVID-19患者在视频透视吞咽研究（VFSS）中观察到的异常吞咽特征。从JH CROWN队列数据库（2020年1月至2022年3月）中，共确定了3,660例需要补充氧气的中重度COVID - 19疾病患者。本研究采用改良的钡餐吞咽损伤量表（MBSImP）提取并报告了VFSS转诊率和吞咽特征。16% （n = 588）的患者出现吞咽困难；只有一半接受了VFSS。其中39.3%的患者严重程度为7级，39%的患者出现误吸，30%的患者出现无症状误吸。MBSImP评分异常的部分包括：抱丸时舌控（评分2/3,40%）、丸运输和舌动（评分3/4,34%）、口腔残留（评分2/4,57.7%）、咽部吞咽开始（评分3/4,65.2%）、喉前叶闭合（评分1/2,64.5%）和咽部残留（评分2/4,50.5%）。总之，这一大型COVID-19患者队列在口腔和咽期表现出无数的吞咽异常，其中无声误吸率明显很高。此外，区分covid -19引起的吞咽困难与拔管后吞咽困难具有挑战性。

期刊介绍： Dysphagia aims to serve as a voice for the benefit of the patient. The journal is devoted exclusively to swallowing and its disorders. The purpose of the journal is to provide a source of information to the flourishing dysphagia community. Over the past years, the field of dysphagia has grown rapidly, and the community of dysphagia researchers have galvanized with ambition to represent dysphagia patients. In addition to covering a myriad of disciplines in medicine and speech pathology, the following topics are also covered, but are not limited to: bio-engineering, deglutition, esophageal motility, immunology, and neuro-gastroenterology. The journal aims to foster a growing need for further dysphagia investigation, to disseminate knowledge through research, and to stimulate communication among interested professionals. The journal publishes original papers, technical and instrumental notes, letters to the editor, and review articles.
