[Liver transplantation with no-heatbeating donor supplied gaseous oxygen during cold preservation in pigs].

Objective To investigate the availability of liver transplantation with non- heart beating (60 min) donors supplied gaseous oxygen by hepatic vein in cold preservation period in pigs. Methods Thirty-six pigs were randomly divided into three recipient groups and three donor groups (group A-15 min of warm ischaemia. group B-60 min of warm ischaemia and group C-60 min of warm ischaemia with gaseous oxygen by hepatic vein during cold preservation period). OTL was performed after four hours cold preservation. Postoperative 5 days survival rate of the liver metabolic, function and inflammatory reaction were observed. Results All animals in group A and C survived after reperfusion for 5 days. but animals in group B died within 3 hours postreperfusion. The damage of liver construction and function were found in group A and group B. There was no significant difference of the changes between group A and C. Conclusions Gaseous oxygen persufflation during cold preservation has important protective and resuscitative effect for liver from long-time no-heart beating donors. It was possible to become a promising method for liver transplantation with no-hearbeating donors.
