【摘要】 目的探讨老年人肺源性心脏病（肺心病）并发低渗血症及高粘血症的诊断与治疗对策。方法对２０例经血浆渗透压及血液流变学检查，证实有低渗血症并高粘血症的老年肺心病患者进行回顾性分析。结果本组低渗血症并高粘血症轻度及中度各８例，重度４例，多见于肺心病危重病例。治疗后症状缓解１５例，死亡５例，病死者为中至重度低渗血症并高粘血症。结论由于临床症状无特异性，老年肺心病并发低渗血症及高粘血症容易漏诊，应引起注意。治疗上应和肺心病的其他并发症同步进行，以减少肺心病患者的死亡。更多还原

【Abstract】 Objective To investigate the diagnosis and treatment of blood hypoosmolality and hyperviscosaemia in aged patients with cor pulmonale. Methods Hypoosmolality and hyperviscosaemia proved by plasma osmotic pressure and hemorheology were analysed in 20 aged patients with cor pulmonale. Results Hypoosmolality and hyperviscosaemia were found in 20 severe cor pulmonale. Eight mild cases and 8 moderate cases (osmotic pressure 260280 mmol/L and 240259 mmol/L, hematocrit >050 and 055) 4 severe cases (osmotic pressure<240 mmol/L,hematocrit>060).After treatment, symptoms of the disease were alleviated in 15 patients and 5 patients died of mild to high degree blood hypoosmolality and hyperviscosaemia. Conclusions It is notable that because of lack of characteristic clinical manifestations, blood hypoosmolality and hyperviscosaemia are easily to be missed in diagnosis. Treatment of the above conditions should be considered during managing complications of cor pulmonale so as to decrease mortality of the disease.更多还原
