The correlation of the lesion and size of cerebral hemorrhage and electroencephalogram wave

Objective: To explore the wave characteristics of continuous electroencephalogram(CEEG) in different lesions and bleeding of cerebral hemorrhage.Methods: The 24 hours CEEGs wave of 60 patients with cerebral hemorrhage were recorded.Results: The abnormal CEEGs in 60 patients with cerebral hemorrhage were obvious,which showed extensive changes.The bilateral or unilateral diffuse θ and paroxysmal δ were found.The abnormal rate of CEEG in shallow layer was higher than that in deep lesions,the abnormal rate of CEEG in patient with 20 to 40 ml or more than 40 ml bleeding was higher than that in patient with less than 20 ml bleeding(P<0.05 and P<0.01).Conclusions: CEEG has diagnostic significance in the evaluation of treatment effects and prognosis of cerebral hemorrhage.
