Abstract

Objective: The aim of this study was to investigate changes in transfusion practice over time in liver transplantation surgery and to evaluate potential causes for changes in practice and report associated perioperative morbidity and mortality. Design: A retrospective cohort study. Setting: A single tertiary referral academic hospital. Participants: Two cohorts of 100 sequential adult primary liver transplant recipients: Early practice (1990-1991) and recent practice (2005-2006). Interventions: None. Measurements and Main Results: Perioperative transfusion and hemoglobin data were recorded. Mortality and postoperative complications were identified up to 30 days postoperatively. Appropriate intergroup statistical comparisons were made; p ≤ 0.05 was considered statistically significant. Compared with the early group, the recent group had significantly fewer perioperative allogeneic red blood cell transfusions, intraoperative autotransfusions, and transfusions of other blood products. No change in perioperative transfusion triggers was identified. There were no significant alterations in perioperative morbidity or mortality. Conclusions: When compared with patients in the early group, recent cohort patients received significantly fewer blood transfusions. The authors attribute this observation to changes in surgical technique rather than a significant alteration in transfusion triggers over the studied time period.
