The Use of EEG in Evaluating the Clinical Efficacy of Repetitive Transcranial Magnetic Stimulation in Coma Patients with Severe Brain Injury
Objective To evaluate the clinical efficacy of EEG in patients with severe brain injury.Methods Select Jiujiang First People's hospital neurosurgery in January 2021 to January 2023 received severe brain injury coma patients 24 cases,Glasgow coma score(GCS)＜9 points,admission to accept repeated transcranial magnetic stimulation awake treatment,observe the EEG related parameters before and after treatment,compared the average power and slow wave ratio(DTR)on different channels,evaluate the application value of EEG in evaluating curative effect.Results After rTMS treatment,83.33％of the patients recovered to grade Ⅰ and grade Ⅱ,and another 4 patients were in grade Ⅲ and grade Ⅳ,but no grade Ⅴpatients,most of the patients basically had a good recovery.Significant difference before and after treatment(P＜0.05);decreasing mean power and DTR on Fp 1,F3,C3,F7 and T3 after rTMS compared with before treatment(P＜0.05).In addition,of the 24 included severe brain injuries,comatose patients had EEG abnormalities of varying degrees,the images mainly show the medium and high amplitude slow wave and θ array hairstyle,25％(6/24)and 41.67％(10/24)respectively.However,all of the above abnormalities were significantly reduced after rTMS treatment,with an improved waveform differentiation.Conclusion EEG is useful in the evaluation of clinical outcome in coma patients with severe brain injury,Repeated rTMS is also worthwhile as a feasible option for getting awake in coma patients with severe brain injury.
