Abstract:
Objective To study the causes, significance of alteration of PtiO 2, PtiCO 2 and pHti in liver tissue during liver ischemia reperfusion (I R). Methods After rabbits were anesthetized, liver ischemia was induced by complete occlusion of the hepatoduodenal ligment for 45 min, then the portal and arterial flow were released, and observed for 120 min for measuring the PtiO 2, PtiCO 2 and pHti in liver tissue and the pathology of the liver during ischemia reperfusion. Results After 15 min of hepatic vascular occlusion, PtiO 2 decreased to 4 mmHg, PtiCO 2 increased fast to (149.63?9.80) mmHg (P
