Abstract: AIM: To explore the relationship of patients with large area cerebral infarction with secondary fervescence and recent prognosis.METHODS: According to the temperature, 200 patients with large area cerebral infarction were divided into fever group( T≥37.5 ℃,80 cases) and non-fever group(T＜37.5 ℃,120 cases) . The incidence rate and case fatality rate of multiple organ failure (MOF) and cerebral hernia, the concomitant disease and infection within 3 months were analyzed.RESULTS: The incidence rates and case fatality rates of MOF, cerebral hernia and diabetes in fever group obviously higher than those got fever onset after 7-14 d.CONCLUSION: Large area cerebral infarction of secondary temperature increase is easily happened in patients with diabetes. The MOF is easily happened in patients got fever in 7 d with high mortality. It is a factor of recent poor prognosis.
