Résumé :

In patients with cirrhosis, both beta-blockers and diuretics decrease the degree of portal hypertension. Since their mechanisms of action differ, the combination of these two substances should induce a more pronounced effect on portal pressure than one of these substances alone. Thus, the hemodynamic effects of furosemide were evaluated in ten patients with cirrhosis receiving beta-blockers. One hour after furosemide (0.75 mg/kg intravenously) administration, cardiac output decreased significantly from 6.2 +/- 0.6 to 5.2 +/- 0.3 l/min and blood volume from 8.0 +/- 1.6 to 5.3 +/- 0.5 l. Mean arterial pressure was not affected. Wedged and free hepatic venous pressures did not change significantly; nor did the hepatic venous pressure gradient (19.6 +/- 1.7 to 18.6 +/- 1.5 mmHg). Azygos blood flow was not affected (0.46 +/- 0.05 to 0.50 +/- 0.07 l/min). In conclusion, this study did not demonstrate that the addition of furosemide to propranolol further decreased portal pressure in patients with cirrhosis. The long-term effects of this combination are unknown and should be tested.
