肝肺综合征(HPS)是指在无原发性心肺疾病时,由肝功能障碍和/或门脉高压、肺内血管扩张及低氧血症组成的三联征。此研究检测印度肝硬化病人中HPS的发生率,并研究它的临床征象和肺血流动力学改变,以及与肝病严重程度的关系。 病人和方法:自1997年9月～1998年8月在SSKM医院门脉高压诊所内,45例经活检证实为肝硬化并排除原发性心肺疾病的患者。平均年龄(41±12.5)岁(17～69)岁,其中男性37例。所有病人均作气泡造影超声心动图检查。阳性患者均进行立位和仰卧位血气分析。有异常血气值者行肺功能试验。HPS的最后确认依靠阳性的气泡造影超声心动图检查和一次动脉血氧分压水平<70mmHg(在立位呼吸室内空气时)。3例HPS患者和24例非HPS患者通
Hepatic-lung syndrome (HPS) refers to the triad of liver dysfunction and / or portal hypertension, pulmonary vasodilation and hypoxemia in the absence of primary cardiopulmonary disease. This study examined the incidence of HPS in cirrhotic patients in India and investigated its clinical signs and changes in pulmonary hemodynamics and its relationship to the severity of liver disease. Patients and Methods: From September 1997 to August 1998, 45 patients with cirrhosis and primary cardiopulmonary disease were confirmed by biopsy in SSKM hospital portal hypertension clinic. The mean age (41 ± 12.5) years (17 ~ 69) years old, including 37 males. All patients were examined by bubble contrast echocardiography. Positive patients were standing and supine position blood gas analysis. Have abnormal blood gas values in lung function tests. The final confirmation of HPS relies on positive bubble contrast echocardiography and an arterial partial pressure of <70 mm Hg (when breathing in the air in the standing position). 3 HPS patients and 24 non-HPS patients
