Abstract

During operations for major hepatic trauma it may be necessary temporarily to deprive the liver of its blood supply by occlusion of the hepatic artery and portal vein. The maximum β€˜safe period’ of total hepatic ischaemia in man is unknown.

In the monkey the ischaemic liver β€˜leaks’ potassium, and levels of this element in the hepatic veins rise during ischaemia reaching a peak immediately after blood supply to the liver is restored. However, critical systemic levels of potassium are never reached and severe biochemical disturbance does not occur until 2 h following revascularization in animals having experienced ischaemic periods of longer than 20 min.
