Objective： To observe the effect of Xingnaojing injection on electroencephalogram(EEG)and prognosis in treating patients with supratentorial intracerebral hemorrhage，and analyzed the relationship between changes of continuous electroencephalogram(CEEG)and the prognosis of patients with supratentorial intracerebral hemorrhage.Methods：Stratified 76 cases of patients with supratentorial intracerebral hemorrhage according to the mild-impairment type，the moderate-impairment type and the severe-impairment type in Glasgowcoma scale(GCS)，and divided theminto the treatment group and the control group randomly，38 cases in each group.The control group was given the routine comprehensive physical treatment in western medicine，while the treatment group additionally received intravenous drip with Xingnaojing injection for 10 days.All the patients received the CEEG examination after hospitalization within 24 h and for 10 days，the statistical analysis of prognosis was conducted after the onset of supratentorial intracerebral hemorrhage for 3 months or at death，the changes of CEEG and prognosis in both groups were compared before and after treatment；and according to the clinicaleffect of CEEG in all the patients，divided the minto the CEEG-effective group(significantly improved+improved)， the CEEG-ineffective group(unimproved+deteriorated)， and analyzed the relationship between changes of CEEG and the prognosis.Results： Compared the clinical effect： On the whole， the improvement of CEEG in the mild-impairment patients and the moderate-impairment patients in the treatment group was better than that in the control group，difference being insignificant(P ＞ 0.05)；the improvement of CEEG of the severe-impairment patients in the treatment group was significantly better than those in the control group(P ＜ 0.05)；in the comparison of the obvious improvement rate and the total improvement rate among patients of all types，except that the total improvement of CEEG of moderateim pairment patients in the treatment group was better than that in the control group(P ＜ 0.05)，there were no significant differences being found in the comparison of the obvious improvement rate and the total improvement rate among patients of the other types in-between the two groups(P＞ 0.05).Compared the prognosis：On the whole，prognosis in the treatment was significantly better than that in the controlgroup(P ＜ 0.05)；comparing the favorable prognosis rate and the death rate of all types of patients，except that the favorable prognosis rate of severe-impairment patients in the treatment group was better than that in the control group(P ＜ 0.05)，there were no significant differences being found in the comparison of the favorable prognosis rate and the death rate among patients of the other types in-between the two groups(P＞0.05).Analyzed the relationship between the clinical effect of CEEG and prognosis：On the whole，prognosis in the CEEG-effective group was better than that in the CEEG-ineffective group( P ＜0.05)；among the mild-impairment patients，the death rate in the CEEG-effective group was lower than that in the CEEG-ineffective group(P ＜ 0.05)，while there were no significant differences being found in the comparison of the favorable rate in-between the two groups(P ＞ 0.05)；among the moderate-impairment patients，the favorable rate was higher and death rate was lower in the CEEG-effective group than those in the CEEG-ineffective group(P ＜ 0.05)；among the servere-impairment patients，the favorable rate in the CEEG-effective group was higher than that in the CEEG-ineffective group(P ＜ 0.05)，while there was no significant difference being found in the comparison of the death rate in-between the two groups(P＞0.05).Conclusion：CEEG has considerable app lication value in the prognosis of patients with supratentorial intracerebral hemorrhage，and the intervention of Xingnaojing injection has significant clinical effect in CEEG and the prognosis of patients with supratentorial intracerebral hemorrhage，especially for the moderate-impairment patients.
