【摘要】 目的　对 2 6例肝硬化合并低氧血症患者进行血气分析 ,探讨肝硬化合并低氧血症的发病机理及发生率。方法　用美国生产的IL130 6型血气分析仪 ,测定 2 6例肝硬化患者及 8例正常人动脉血中PaO2 、SaO2 、PaCO2 及pH值。比较两组之间的差异。结果　研究组与对照组比较 ,研究组PaO2 明显下降 ,P <0 .0 1,研究组中低氧血症的发生率达 5 3 .8%。结论　肝硬化如出现并发症或肝贮备功能下降者合并低氧血症发生率明显增高更多还原

【Abstract】 Objective To study the hypoxemia in 26 patients with cirrhosis of liver with blood gas analyses. Methods PaO 2, SaO 2, PaCO 2 and pH of arterial blood were determined in 26 cases with hepatic cirrhosis and 8 healthy subjects by using the apparatus for blood gas analysis (IL 1306) made in USA. Result Compared the studied group with the control group, PaO 2 fell significantly ( P <0.01). The frequency of hypoxemia in the studied group was 53.8%. Conclusion The incidence of hypoxemia increases in cirrhotic patients when the hepatic reserve function falls.(Shanghai Med J, 2000,23∶481 482)更多还原
