Early brain protection proventing the low blood pressure brain edema of general surgery patients in operation

Objective To investigate the methods and efficacy of the early brain protection to prevent the brain edema with low blood pressure patients of general surgery in operation.Methods Fifty-four patients with intraoperative low blood pressure were divided into two groups,27 cases in each group.Protective measure such as hypothermia,osmotic diuretics,hormone,tranquillizer and other measures before symptoms of brain edema appeared were given in early brain protection group.The same protective measures after symptoms of brain edema appeared was given in other group.Then the effacay was evaluated by Glasgow standard of narcose scroe.Results In early brain protection group,brain edema occurred in 7 cases(25.9%) after operation,and 3 cases(11.1%) were death.In the other group,brain edema occurred 11 cases(40.8%),and 5 cases(18.6%) were death.The scores of Glasgow standard of coma was statistically significant differences at the 1st day,the 3rd day,the 5th day and the 7th day between two groups(P0.05).Conclusion The early brain protection can prevent the low blood pressure brain edema and can decrease the death rate and the incidence of brain edema.
