RESUMEN
The scarcity of liver donors has increased the necessity to closely select recipients to improve liver transplantation outcomes. If we were able to recognize those recipients with the best outcomes, then this could result in a better and more accurate selection of our donors. Hemoderivate transfusion is one of the main important factors to analyse. We reviewed the data of all of our liver transplant recipients from May 1998 to December 2013 and selected 888 patients with complete records. We divided these patients into 5 groups to get a better selection. We found differences between these groups with respect to the following: recipient age at the time of transplantation, percentage of patients with hepatocarcinoma, and those with hepatitis C virus (HCV)-related etiology. Also, intensive care unit (ICU) time and the need for retransplantation were distinctive factors with observable differences between our groups. With respect to model for end-stage liver disease (MELD) score, the groups were clearly defined by their mean MELD score, finding significant statistical differences between these groups with respect to this score. We also found a significant relationship between MELD scores and survival in the different groups. This is also the first review in which the MELD score and intraoperative transfusion requirements are well associated with patient and graft survival.
