Splanchnic Tissue Perfusion in Acute Experimental Pancreatitis

Abstract

Background: Gut hypoperfusion may have a role in the pathogenesis of multiple organ failure, which is a the main cause of death in severe acute pancreatitis. We hypothesized that gut hypoperfusion is present early in acute pancreatitis and that supporting the systemic hemodynamics by fluid resuscitation would prevent this. Methods: In a pig model of randomized, controlled experimental hemorrhagic pancreatitis induced by Na-taurocholate the animals were divided into four groups (n = 6 for each): 1) pancreatitis, 2) control, 3) pancreatitis and fluid resuscitation to keep the pulmonary capillary wedge pressure at 5 to 6 mmHg, and 4) control and fluid resuscitation as in group 3. Splanchnic perfusion was assessed by means of local PCO₂ gap with intestinal tonometer, oxygen delivery and consumption, lactate production, and blood flow. The follow-up time was 6 h. Results
