dc.descriptionIn 18 dogs, previously anesthetized with sodium pentobarbital for the surgical preparation, catheterism and monitoring, the action of sodium pentobarbital (7.5 mg/kg) and enflurane (1.5 - 2%) in the liver circulation was studied. Measurements of the following parameters were made in four different times, before and 15, 30 and 60 min after the drug administration. By direct determination: hepatic artery flow, portal vein flow, mean pressure of the abdominal aorta, peripheral arterial pressure (mean), pressure in the caudal cava vein, portal pressure; and by indirect determination: total flow, arterial-cava gradient, portal-cava gradient, resistance in the hepatic artery territory, resistance in the territory of the portal vein, and total resistance. Based on the results, it is concluded that in the experiment's conditions: sodium pentobarbital doesn't change significantly the hepatic circulation, and enflurance produces a fall in the total hepatic flow, by reducing the portal flow, without alterations of the hepatic arterial flow. It diminishes the total hepatic resistance by diminishing the arterial resistance without alterations of the portal resistance; it diminishes the arterial-cava gradient in consequence of the reduction of the abdominal aorta pressure and of the portal pressure, but it seems that the caudal cava pressure is not altered. It also occurs a fall in the peripheral mean pressure.
