Abstract: This article discussed the risk factors of aspiration in stroke patients and the value of using contrast examination to assess the swallowing function of patients. A total of 90 patients with aspiration after confirmed stroke were selected as aspiration group, and 90 patients without aspiration after stroke were selected as control group during the same period. The risk factors of aspiration were analyzed, and the swallowing function of the two groups was evaluated by video fluoroscopic swallowing study (VFSS). The results showed that the NIHSS score, past stroke rate, and stroke location of the aspiration group were compared with the control group, and the difference was statistically significant. High NIHSS scores in stroke patients, previous stroke history, and brainstem stroke were independent risk factors for aspiration. The measured values of OTT and STT of patients in the aspiration group were higher than those of the control group, while the measured values of DT were lower than those of the control group. It shows that severe neurological deficits, brainstem stroke, and past history of stroke are risk factors for aspiration in stroke patients. The use of VFSS has high clinical value for detecting and diagnosing swallowing dysfunction in stroke patients.
