目的 探讨自发性脑出血病人的平均动脉压与临床预后的关系。方法 就我院 1996年 1月至 1997年 12月诊治的 338例脑出血病人发病 2 4小时内最高平均动脉压 (MAP)的 4周内死亡率进行分组研究 ,并就年龄、出血量及中线偏移程度与MAP进行相关分析。结果 4周内死亡率随MAP增高而增加 ,MAP≥ 2 0kPa时死亡率明显增高(6 6 3 % ,P <0 0 1) ,MAP与年龄显著负相关 (r =- 0 12 2 ,P <0 0 5 ) ,与出血量、中线偏移程度显著正相关 (r =0 15 2 ,P <0 0 1;r =0 16 9,P <0 0 1)。结论 MAP对脑出血病人临床预后有一定作用 ,其影响因素可能与年龄、出血量及中线偏移程度有关
Objective To explore the relationship between mean arterial pressure and clinical prognosis in patients with spontaneous intracerebral hemorrhage. Methods A total of 338 patients with cerebral hemorrhage diagnosed and treated in our hospital from January 1996 to December 1997 were divided into two groups according to the 4-week mortality rate of the highest mean arterial pressure (MAP) within 24 hours. The age, blood loss, Correlation analysis between MAP and degree of offset. Results The mortality increased with the increase of MAP within 4 weeks. The mortality was significantly higher at MAP 2 0 kPa (6 6 3%, P 0 01) and MAP was significantly negatively correlated with age (r 0 0 12 2, P < There was a significant positive correlation between the amount of bleeding and the degree of midline deviation (r = 0 15 2, P <0.01; r = 0 16 9, P 0 01). Conclusion MAP may play a role in the clinical prognosis of patients with ICH, and its influencing factors may be related to the age, amount of bleeding and the degree of midline deviation
