目的　探讨感染对脑血管病发生发展的影响。方法　回顾分析 115 6例脑血管病感染住院患者临床资料 ,并对脑出血、脑梗死起病前后感染情况进行比较。结果　①脑出血组合并感染患者 ( 2 0 6 2 % )显著高于脑梗死 ( 9 34% ) (P <0 0 1) ,两者都以起病后合并感染居多。②感染以细菌为主 ,呼吸道感染占首位( 5 2 5 % ) ,泌尿道感染其次。③ 115 6例患者院内死亡 76例 ,病死率 6 5 7% ,感染组较非感染组病死率高 (P<0 0 1)。④脑血管病有感染者比无感染者血白细胞计数明显增多 (P <0 0 1)。⑤脑出血与脑梗死的部位与感染的发生有相关性 (P <0 0 5 )。结论　脑出血患者感染的发生率高于脑梗死 ,脑血管病患者起病后合并感染是其致残、致死的重要原因之一。 Objective To investigate the impact of infection on the occurrence and development of cerebrovascular disease. Methods A retrospective analysis of 1156 cases of cerebrovascular disease inpatients with clinical data, and cerebral hemorrhage, cerebral infarction before and after onset of infection were compared. Results (1) Patients with combined intracerebral hemorrhage (20.62%) were significantly higher than those with cerebral infarction (93.4%) (P <0.01), both of whom had the highest incidence of infection after onset. ② infection mainly bacteria, respiratory tract infection accounted for the first (52.5%), followed by urinary tract infection. (3) There were 76 cases of nosocomial death in 116 cases with a mortality rate of 65.7%. The case fatality rate of infected group was higher than that of non-infected group (P <0.01). ④ The number of blood leukocyte in patients with cerebrovascular disease was significantly higher than those without infection (P <0.01). ⑤ The site of cerebral hemorrhage and cerebral infarction was associated with the occurrence of infection (P <0.05). Conclusions The incidence of cerebral hemorrhage is higher than that of cerebral infarction. One of the most important causes of morbidity and mortality is the complicated infection after onset of cerebrovascular disease.
