目的 :探讨脑出血病人低磷血症的发生率及预后关系。方法 :分析 2 0 0 1年 1月～ 2 0 0 2年 12月资料完整的 2 3 8例脑出血患者发生低磷血症的危险因素及预后关系。结果 :脑出血病人低磷血症发生率为 8 82 % ,多发生于严重脑出血患者 ,低磷血症组病死率为 71 42 % ( 15 /2 1) ,与无低磷血症组病死率 12 44 % ( 2 7/2 17)相比有显著差异 (P <0 0 1)。结论 :低磷血症常发生了严重脑出血患者 ,是致死的危险因素 ,应加以预防 Objective: To investigate the incidence and prognosis of hypophosphatemia in patients with intracerebral hemorrhage. Methods: To analyze the risk factors and prognosis of hypophosphatemia in 238 cases of complete cerebral hemorrhage from January 2001 to December 2002. Results: The incidence of hypophosphatemia in ICH patients was 82 82%, mostly in patients with severe cerebral hemorrhage. The mortality rate in hypophosphatemia group was 71 42% (15/21) There was a significant difference between the rate of 12 44% (2 7/2 17) (P 0 01). Conclusion: Hypophosphatemia often occurs in patients with severe cerebral hemorrhage, is a risk factor for lethal, should be prevented
