Effect of extended cold ischaemia with UW solution on graft function after liver transplantation.
Studies in animals on the use of UW solution in liver transplantation have shown an inverse relation between cold ischaemia time (CIT) and graft function. There are few clinical data on this relation in human beings. We have investigated the effect of extended cold ischaemia in a prospective study. We assessed early graft function and subsequent outcome for 306 consecutive elective liver transplantations; for analyses, grafts were grouped according to CIT (< 12 h group A, > or = 12 h group B), since a preliminary study identified 12 h as a significant cut-off point. Initial graft function was better in group A than group B, as shown by maximum alanine aminotransferase activity (mean 623 [805] vs 946 [1148], p = 0.02), bile production on days 1-3 (p < 0.05), maximum serum bilirubin by day 10 (206 [166] vs 244 [163] mumol/l, p = 0.04), and frequencies of primary non-function (1 [0.4%] vs 4 [7%], p = 0.006) and hepatocyte necrosis on routine biopsy sample after reperfusion (18% vs 31%, p = 0.04). Long-term outcome was also better in group A than group B; graft and patient survival rates were higher and fewer retransplantations were needed. These findings suggest that cold ischaemia in UW solution for longer than 12 h is a risk factor for graft function and patient survival. We recommend that the limit of the safe CIT be reconsidered.
