Abstract:
Objective To explore the prognostic value of long-time EEG monitoring and the clinical examination index in comatose patients.Methods The long-time EEG monitoring and the modified Glasgow coma scale were done in 26 comatose patients(15 patients were male;11 patients were female;17—40 years old)in acute phase.The complexity of cerebral hemisphere was analyzed by computer.The patients were followed-up for 2 months and evaluated by Glasgow outcome scale.The correlation between the long-time EEG monitoring,clinical examination index and the prognosis of the patients was analyzed.The time- variation of hemisphere complexity and the relationship between prognosis and entropy were observed. Results The specificity(77.8%)and accuracy rate(92.3%)of long-time EEG monitoring in predicting the outcome of the acute comatose patients were higher than those of clinical examination.The EEG index appeared more closed-up with prognosis than clinical examination.The correlation coefficient between the EEG index and the modified Glasgow prognosis scoring was r=0.81(P
