Abstract:

Objective　To investigate the effect of sprayed acid and cold stimulation on improving the swallowing function in stroke patients with dysphagia. Methods　It was a randomized controlled trial. A total of 81 stroke patients with dysphagia admitted to Department of Neurology, Jieyang People's Hospital from November 2020 to June 2022 were selected as the study subjects, and were divided into a control group (40 cases) and an observation group (41 cases) by the random number table method. In the control group, there were 21 males and 19 females, aged (69.85±9.74) years; in the observation group, there were 27 males and 14 females, aged (70.02±9.63) years. On the basis of conventional treatment and nursing, the control group was treated with acid and iced cotton stick stimulation rehabilitation therapy, while the observation group was treated with sprayed acid and cold stimulation rehabilitation therapy. Standardized Swallowing Assessment (SSA) score was used to compare the swallowing function of the two groups before intervention, one week after intervention, and two weeks after intervention, and the differences of comfort level and operation duration were compared between the two groups.Independent sample t test or analysis of variance were used for the measurement data, and χ² test was used for the count data. Results　Before intervention, there was no statistically significant difference in the SSA score between the two groups (P>0.05). One week and two weeks after intervention, the SSA scores of the observation group [(23.90±4.44) points and (21.05±3.32) points] were significantly lower than those of the control group [(27.55±4.64) points and (26.05±4.72) points], with statistically significant differences (both P<0.001). The scores of pharyngeal pain and nausea/discomfort in the observation group [(0.27±0.09) points and (0.60±0.09) points] were significantly lower than those in the control group [(0.80±0.11) points and (1.58±0.20) points], with statistically significant differences (both P<0.001). There was no statistically significant difference in the oropharyngeal discomfort score between the two groups (P>0.05). The operation duration of the observation group [(1 111.29±241.44) s] was significantly shorter than that of the control group [(1 244.25±323.27) s], with a statistically significant difference (t=2.101, P=0.039). Conclusion　Sprayed acid and cold stimulation is simple to operate, can improve the patients' comfort level, shorten the operation duration, and effectively improve the patients' swallowing function, which can provide references for the rehabilitation training in stroke patients with dysphagia.
