摘　　要：目的：探讨肝硬变患者的门静脉压力、肺动脉压力的变化及其与肝功能损害间的关系。方法：应用阻抗微分图，测定４７例肝硬变患者的门脉指数（ｈＤ／ｈＳ）、平均肺动脉压（ＰＰＡ）；将肝硬变患者的肝功能按ＣｈｉｌｄＰｕｇｈ分级（Ａ级１４例，Ｂ级２１例，Ｃ级１２例），并同时测定动脉血氧分压（ＰａＯ２）。结果：反映门静脉压力的参数（ｈＤ／ｈＳ）与腹水的发生率有关。ｈＤ／ｈＳ及ＰａＯ２参数在ＰＰＡ增高组与正常组间差异有显著性，且ｈＤ／ｈＳ与ＰＰＡ的升高与肝功能损害程度呈正相关。结论：阻抗微分图可以反映肝硬变患者的肝功能损害程度及门静脉压力、肺动脉压力的变化。Objective:To study the changes of the portal pressure and pulmonary pressure in liver cirrhosis and their relation to impaired hepatic function.Methods:hD/hS and P PA were measured on electrical impedance plethysmogram(EIP) in 47 patients with liver cirrhosis.According to Child Pugh's classification,the patients were divided into group A( n =14),B( n =21) and C( n =12) and PaO 2 were determined.Results:The parameters of the portal pressure were referable to the rate of ascites production.hD/hS and PaO 2 in cases with elevated P PA differed markedly from those of normal individuals,and elevated hD/hS and P PA correlated positively with severity of impaired hepatic function.Conclusions:EIP can evaluate the severity of hepatic function in cirrhotic patients and the alteration of the portal and pulmonary pressure.Change in pulmonary pressure may be used as one of criteria for supplementary diagnosis.
