对21例肝硬化腹水病人作肺功能测定,并与50名正常人进行对照。肝硬化组VC为93.67±12.57%,对照组为102.47±15.22%,P<0.05;肝硬化组MVV 89.33±25.4%,对照组127.48±28.44%,P<0.001;肝硬化组FRC 2362.19±845.08%,对照组3085±837.92%,P<0.01;肝硬化组FEV_1 70.1±12.79%,对照组为77.74±9.18%,P<0.05。这些结果都说明在肝硬化腹水时有肺活动受限、肺顺应性下降、气道阻力增高和肺通气量减少。 Pulmonary function tests were performed on 21 patients with cirrhosis and ascites and were compared with 50 healthy controls. The VC in the cirrhosis group was 93.67 ± 12.57%, the control group was 102.47 ± 15.22%, P <0.05; the MVV in the cirrhosis group was 89.33 ± 25.4%, the control group was 127.48 ± 28.44%, P <0.001; the cirrhosis group was FRC 2362.19 ± 845.08% , 3085 ± 837.92% in the control group, P <0.01; in the cirrhosis group, FEV_1 was 70.1 ± 12.79% in the control group and 77.74 ± 9.18% in the control group, P <0.05. These results indicate that there is limited pulmonary activity, decreased lung compliance, increased airway resistance, and decreased pulmonary ventilation in cirrhotic ascites.
