title: [Hepatopulmonary syndrome in decompensated cirrhotic patients].
abstract: Hypoxemia is common in cirrhotic patients and, when obvious pulmonary or cardiac causes are discarded, it is attributed to the so-called hepatopulmonary syndrome. The aim of this work was to assess the frequency of hypoxemia and orthodeoxia and its relationship with the degree of liver failure, in cirrhotic alcoholic patients. We studied 30 alcoholic cirrhotics. In all, arterial blood gases were measured in supine and standing positions, in 26 a chest X ray examination was done and in 20 a spirometry. Twelve patients had a subnormal PaO2 and this parameter fell more than 105 when assuming the standing position in one of these. The same reduction was observed in two subjects with normal supine PaO2. In the chest X ray examinations, pleural effusions were observed in five hypoxemic subjects and four with normal PaO2. Likewise minimal athelectasis was found in six and seven subjects and intestinal infiltrates in one of the two subjects. A significant association between hypoxemia and Pugh score was observed. Similarly, subjects with hypoxemia is frequent in alcoholic cirrhotic patients and, since it is not associated to obvious pulmonary causes, it may be attributed to the hepatopulmonary syndrome.
