Effect of secretin on portal venous flow.
In this study we evaluated the effect of two different doses of secretin on portal haemodynamics (by pulsed Doppler associated with real time ultrasound) in 24 healthy humans. In 12 subjects (group A) we administered an intravenous dose of 75 clinical units of secretin and in the remaining 12 (group B) a dose of 20 CU. In all subjects the following parameters were studied before, during, and fo...
متن کاملRelationship of splanchnic blood flow and portal venous resistance to elevated portal pressure in the dog.
To determine the relationship of splanchnic blood flow and portal venous resistance to elevated portal pressure, in situ perfusion of the splanchnic circuit was carried out in 12 freshly killed dogs at varying perfusion rates and degrees of acute and chronic portal vein constriction. In six normal dogs before being killed, portal pressure averaged 8-8 +/- 1-2 mmHg and portal flow 658 +/- 81 ml/...
متن کاملEffect of portal hypertension on splenic blood flow, intrasplenic extravasation and systemic blood pressure.
We have previously shown that intrasplenic fluid extravasation is important in controlling blood volume. We proposed that, because the splenic vein flows in the portal vein, portal hypertension would increase splenic venous pressure and thus increase intrasplenic microvascular pressure and fluid extravasation. Given that the rat spleen has no capacity to store/release blood, intrasplenic fluid ...
متن کاملInfluence of Levarterenol on Portal Venous Flow in Acute Hemorrhage
In anesthetized dogs, the effects of hemorrhage alone upon the mesenteric circulation have been compared with those of hemorrhage plus 1-norepinephrine. With norepinephrine, the portal venous flow is slightly less than in the case of untreated hemorrhage. In view of the significantly higher blood pressure during the norepinephrine infusions, however, the mesenteric resistance is considerably gr...
