Changes of the white blood cell(WBC) count and it's clinical significance in acute cerebral infarction

Objective: To discuss the correlation of peripheral WBC in acute cerebral infarction and the development and prognosis of the disease.Methods: Rertrospective statistics of 2812 severe cerebral infarction patients were divided into two groups according to WBC count:WBC count larger than 10×10 9/L was taken as abnormal group and normal group include WBC count smaller than 10×10 9/L. WBC count at three stage(1～3,3～6,7～10d) was calculated at the same time with death rate,consciousness.An analysis of the WBC count of the dead and the survivors was made.Results: The fatality rate of abnormal groups obviously higher normal ones. The fatality rate was increasing with the rise of WBC count,which is obviously higher in the dead than in the survivors.There was correlation between the increase of WBC count the serverity of consciosness state.Conclusion: It is the stress after brain injury to a certain serverity that leads to the increase of WBC count.It's the important reason for the serious condition and poor diagnosis of the patients. As an obvious correlation is established between WBC count and the outcome,WBC count can be a simple and easy evaluation in the prognosis of cerebral vessles.
