对34例肝硬化伴腹水病人进行血气检查,与50名正常人进行对照。肝硬化病例P_aO_2值低于80mmHg,平均76.9±3.73,而正常人为93.8±10.3,t=10.63,P<0.01。S_aO_2为94.8±10.3,而对照组为96.4±1.13,t=3.07,P<0.01。在肝硬化,除肝细胞与枯氏细胞功能减退之外,尚有门—肺循环分流,肺内动—静脉分流、肺通气—灌注比率异常等。这些均可导致P_aO_2与S_aO_2降低,以及各种酸碱失衡。因此肺组织抵抗力降低、病人易患感染与ARDS,这些均是死亡的主要原因。
Thirty-four patients with liver cirrhosis and ascites were inspected for blood gas, compared with 50 healthy controls. The value of P_aO_2 in cirrhotic patients was lower than 80mmHg, with an average of 76.9 ± 3.73, while the normal rate was 93.8 ± 10.3, t = 10.63, P <0.01. S_aO_2 was 94.8 ± 10.3, while the control group was 96.4 ± 1.13, t = 3.07, P <0.01. In liver cirrhosis, in addition to liver cells and cell dysfunction, there are door - pulmonary circulation shunt, pulmonary shunt - venous shunt, pulmonary ventilation - perfusion rate abnormalities. These can lead to P_aO_2 and S_aO_2 decreased, and a variety of acid-base imbalance. Therefore, reduced lung tissue resistance, susceptibility to infection and ARDS patients, these are the main causes of death.
