Abstract: Objective To explore the nursing strategy and effect of cognitive nursing intervention combined with functional training in patients with sudden deafness(SSHL), and to evaluate the clinical application effect. Methods A total of 80 patients with sudden deafness and tinnitus in department of otorhinolaryngology head and neck surgery, Shanghai Ninth People's Hospital, Shanghai Jiaotong University School of Medicine from December 2017 to December 2018 were randomly divided into study group and control group according to the date of hospitalization. Both groups were given antiviral drugs, microcirculation improvement drugs, hyperbaric oxygen therapy and hormone tympanic injection therapy. The control group was given routine nursing of otorhinolaryngology head and neck surgery. In the study group, the implementation of combined cognitive nursing intervention under the basic routine functional training was compared between the two groups in terms of the improvement of negative emotions, curative effect and overall quality of life of sudden deafness patients after intervention. Results The effective rate of the study group was 90.0%, which was significantly higher than 67.5% of the control group. The difference of the hearing effect between the two groups was statistically significant(P<0.05). The SCL-90 symptom checklist scores of sudden deafness patients with tinnitus after intervention in the study group were significantly lower than those in the control group(1.55±0.96 vs. 1.95±0.78, P<0.05). The air conduction threshold levels of sudden deafness patients with tinnitus after intervention in the study group were significantly lower than those in the control group(26.08±3.29 vs. 31.03±4.06, P<0.05). The scores of daily activities, psychological state, sleep disorders, social relations and quality of life in the study group were significantly lower than those in the control group(all P<0.05). Compared with the control group, the difference was statistically significant(all P<0.05). Conclusion The application of cognitive intervention combined with functional training nursing strategy in sudden deafness patients can effectively alleviate the negative emotions of patients, improve the compliance of patients with treatment, help the recovery of disease, improve the level of patients' hearing threshold, and improve the quality of life of patients.
