低渗血症对肺心病并发肺性脑病的影响及临床意义

The Clinical Significance of Hyposmolarity in Pulmonary Encephalopathy Complicated with Pulmonary Heart Disease

目的 :探讨低渗血症对肺心病并发肺性脑病的影响及其临床意义。方法 :肺心病患者 12 0例 ,再根据血气分析及血浆胶体渗透压筛选出 6 1例患者分为 3组 :①肺脑组 (肺性脑病组 ) 2 2例 ;②混合组 (肺性脑病合并低渗血症组 ) :18例 ;③低渗组 (低渗血症组 ) :2 1例。 3组患者抽取静脉血 2ml测定血钠、血钾、血氯、血糖、血尿素氮 ,另抽取动脉血 2ml测定动脉血氧分压和动脉血二氧化碳分压。并对 3组的血电解质、血浆胶体渗透压及病死率进行比较。结果 :混合组的血浆渗透压、病死率均明显高于肺脑组 (P均 <0 .0 5 )。结论 :低渗血症可明显加重肺心病并发肺性脑病患者的病情 ,使死亡率增高。早期诊断及时治疗是改善病人预后的关键。

objective:To determine the clinical significant and effect of hyposmolarity on complication of pulmonary heart disease:pulmonary encephalopathy.Methods:According to the results of PaO 2, PaCO 2,and plasma osmotic pressure,61 patients were divided into three groups:pulmonary encephalopathy group(22 patients),mixture group(18 patients)hyposmolarity group(21 patients).Na +、K +、Cl -, Glu (Blood Glucose)、BUN,PaO 2、PaCO 2 were detected respectively in 61 patients.Results:plasma osmotic pressure and mortality of pulmonary encephalopathy companies hyposmolarity was significantly higher than that of pulmonary encephalopathy (P>0.05).Conclusion:Hyposmolarity significantly affect the prognosis of pulmonary encephalopathy,The accurate diognosis as early as possible and active theraphy was a key of importance of prognosis in patients.
