Objective: To explore the effects of acupuncture, hyperbaric oxygen and basic rehabilitation training on electroencephalogram and clinical symptoms in children patients with dysphagia after viral encephalitis. Methods: A total of 142 children with dysphagia after viral encephalitis admitted to our hospital were randomly divided into a study group (n=71) and a control group (n=71). The control group was given basic rehabilitation training and routine symptomatic treatment, and the study group was additionally given acupuncture and hyperbaric oxygen therapy. The swallowing function, electroencephalogram (EEG) and clinical symptoms were compared between the two groups before and after treatment. Results: The total effective rate was higher in the study group than that in the control group, and there was significant difference in clinical efficacy between the two groups (P<0.05). After the treatment, the swallowing function in two groups was significantly improved, and the swallowing function in the study group was better than that in the control group (Z=7.62, P<0.05). The recovery times of consciousness disorder, convulsion, speech disorder, cranial nerve disorder and limb dysfunction in the study group were shorter than those in the control group (P<0.05). The abnormal rate of EEG and the incidence rate of aspiration pneumonia within 6 months in the study group were lower than those in the control group (P<0.05). Conclusion: Acupuncture, hyperbaric oxygen and basic rehabilitation training for children with dysphagia after viral encephalitis can have exact efficacy, and promote the recovery of swallowing function, clinical symptoms and EEG, and reduce the occurrence of aspiration pneumonia during convalescent stage.
