Liver function and arterial blood oxygen reserves correlation Study in patients with decompensated cirrhosis

[Objective]To investigate patients with decompensated cirrhosis the arterial oxygen(PaO2),oxygen saturation of arterial blood(SaO2) and the partial pressure of carbon dioxide(PaCO2) changes in the evaluation of arterial blood oxygen hepatopulmonary syndrome clinical diagnostic value for the diagnosis and prevention hepatopulmonary syndrome and provide a theoretical basis.[Methods]Sixty cases of liver decompensated cirrhosis in patients were selected.Blood Gas Analycer was used to measure arterial oxygen pressure,oxygen saturation,carbon dioxide partial pressure.The same period hospitalization normal 60 cases for the control were selected.The PaO2 and SaO2,PaCO2 were compaired.Decompensated cirrhosis of the liver function in patients were undertaken Child-Pugh classification:A 17,B 27,C 16 cases.PaO2 and SaO2,PaCO2 were compaired among the different classification.[Results] The incidence of hypoxemia in patients with liver cirrhosis was 48 percent.① PaO2 was markedly different between cirrhosis group and normal control group(P0.01),and the levels of SaO2,PaCO2 had no difference between liver cirrhosis group and normal control group(P0.05);②PaO2 and SaO2 values existed significantly difference between the different grade of Child-Pugh classification(P0.01),but PaCO2 levels had no difference(P0.05),with the Child-Pugh classification increasing,PaO2 and SaO2 values showed a downward trend.[Conclusion ]The incidence of hypoxemia in patients with liver cirrhosis high.② With the incidence of hypoxemia Child-Pugh classification of liver function and a higher ladder up.③ Blood gas analysis on hepatopulmonary syndrome has diagnostic value.④ Patients with cirrhosis should be done as early as blood gas analysis.
