title: Red blood cell transfusion in liver transplantation: a case-control study.
abstract: BACKGROUND
  We aimed to analyze the influence of intraoperative blood transfusion on postoperative complications and survival and to identify the preoperative variables associated with greater intraoperative bleeding.
  
  
  METHODS
  Thirty-one elective liver transplantations (OLT) without blood transfusion performed between 1986 and 2002 (group 1) were compared with 62 patients (group 2) who underwent elective OLT with intraoperative transfusion after matching for gender, disease severity, and chronology.
  
  
  RESULTS
  The hemoglobin and hematocrit values were significantly greater in group 1 compared to group 2. No significant differences were reported for the other parameters. In particular, the type of surgical technique had no influence on the blood requirement. As expected the nontransfused patients received less autologous packed red blood cells compared with the transfused patients. No differences were observed in either group for mean CIT, ICU and hospital stay, or acute rejection. A significant difference was observed in the number of postoperative infectious episodes, which was higher in group 2 (28 vs 5, P = .01). Graft and patient survivals at 3 months and 5 years did not differ significantly between groups.
  
  
  CONCLUSIONS
  OLT without blood transfusion may be achieved in the presence of good recipient conditions. Lower preoperative hemoglobin and hematocrit values were associated with greater intraoperative transfusions.
