中風患者螢光吞嚥攝影檢查嗆入、吸入與否與喉上抬能力之關係

Abstract

Objective: Post-stroke dysphagia is associated with increased morbidity and mortality in acute stroke patients due to malnutrition or aspiration. This study compares the hyolaryngeal movement during swallowing between post-stroke dysphagia patients with and without penetration/aspiration by videofluoroscopy swallowing study (VFSS). The goal was to find out possible defects in swallow mechunism for improving post-stroke dysphagia swallowing training. Method: We retrospectively collected VFSS images from stroke in-patients in a medical center in Central Taiwan from October 2015 to April 2017. The subjects were subdivided according to the VFSS results and 8-point penetration-aspiration scale (PAS) into those with penetration/aspiration (PAS ≥ 3) and those without penetration/aspiration (PAS ≤ 2). The time expenditure of laryngeal excursion, the percentage of hyoid/thyroid cartilage displacement, and the velocity of hyoid and thyroid cartilage movement were compared between the two groups. Results: A total of 60 patients were recruited in the study. There were no significant differences between the two groups in age, sex, interval between stroke onset and VFSS, type of stroke, and hemiplegic side. The penetration/aspiration group showed slurred laryngeal elevation and reposition slower vertical movement, and slower back-and-forth vector velocity of thyroid cartilage. There were no significant difference between the two groups in terms of horizontal/vertical displacement percentage of hyoid/thyroid cartilage, percentage of hyoid/thyroid cartilage movement vectors, horizontal/vertical movement velocity of the hyoid, horizontal movement velocity of thyroid cartilage, and vector velocities of hyoid and thyroid cartilage. Conclusions: Post-stroke dysphagia patients with penetration/aspiration showed slower laryngeal excursion, slower vertical velocity of the thyroid cartilage, and slower back-and-forth vector velocity of the thyroid cartilage than patients without aspiration/penetration. Future studies should investigate methods for enhancing the efficiency of the muscles involved in vertical laryngeal movement to prevent penetration/aspiration.
