摘　　要：目的对68例肝硬化患者的血气变化进行分析。方法采集观察组和健康对照组桡动脉血,用美国Nova公司PHOX型血气分析仪进行测定。结果观察组68例肝硬化患者氧分压(PaO2)显著下降,低氧血症的发生率为52.9%,与健康对照组比较差异有统计学意义(P<0.01);肝功能Child-Pugh分级C级PaO2显著下降、低氧血症的发生率为88.0%,与A级、B级比较差异有统计学意义(P<0.01)。结论肝硬化患者肝储备功能越差,发生低氧血症的概率就越大,应引起临床重视,若能及时给予相应的治疗可以改善患者的症状。Objective To analyze the arterial blood gas changes of 68 patients with liver cirrhosis.Methods Blood samples were collected and measured from the radial artery,and detected with PHOX blood analyzer of the United States Nova company,and divided into two groups which were observation group and control group.Results Compared with the control group,the level of PaO2 in 68 patients with liver cirrhosis of observation group significantly decreased and the incidence of hypoxemia was 52.9%,with significant differences（P〈0.01）.Compared with A,B grade,the level of PaO2 of C grade classified by liver function Child-Pugh classification was significantly decreased,and the incidence of hypoxemia was 88.0%,with significant differences（P〈0.01）.Conclusion The worse liver reserve functions of cirrhosis patients are,the greater probability occurrence of hypoxemia is,so more attention should be paid;and appropriate and timely treatment could improve the patient symptoms.
