Objective:To observe the effects of Shenmai Injection on the blood pressure and recovery of brain function for the aneurysmal subarachnoid hemorrhage patients.Methods:According to below the level of systolic pressure at 130mmHg after clipping of the cerebral aneurysm

65 cases enrolled have been divide into two groups randomly

In addition to the routine treatment

Shenmai treatment group were intravenous injection of 40%Shenmai Injection for 7 days.We compared the mean arterial pressure

the index of middle cerebral artery by TCD and Glasgow coma score(GCS) between two groups before and on the 3st and 7rd day postoperative

also we compared Glasgow outcome scale(GOS) at discharge.Results:Shenmai Injection raised the blood pressure of treatment group

the degree of cerebral vasospasm

the GCS and GOS score of treatment group were better than control group.Conclusion:By raising the mean arterial pressure of postoperative patients of cerebral aneurysm

Shenmai Injection could raise cerebral perfusion pressure

improved the recovery of brain function.
