title: [Effects of different transfusion on intraoperative blood loss and postoperative drainage volume in posterior lumbar spinal surgery].
abstract: OBJECTIVE
  To explore the effects of autotransfusion on intraoperative blood loss and postoperative drainage volume in posterior lumbar spinal surgery.
  
  
  METHODS
  From June 2010 to January 2012, a total of 183 patients with lumbar disease were enrolled. There were 74 males and 109 females with an average age of 56.6 (31-81) years. There were lumbar disc herniation (n = 80), lumbar stenosis (n = 69), lumbar spondylolisthesis (n = 32) and discogenic pain (n = 2). And one-level (n = 83) and two-level (n = 100) operations were performed. The treatments were non-transfusion (n = 34), auto-blood (n = 109) and allogeneic blood (n = 20) and both (n = 20).Operative duration, operative level, intraoperative autologous blood transfusion, intraoperative allogeneic blood transfusion, intraoperative blood loss, immediate drainage volume, duration of drainage tube and final drainage volume were recorded.
  
  
  RESULTS
  The mean intraoperative blood loss was (369.4 ± 284.0) ml and (568.8 ± 398.7) ml for two-level operation, there were significant differences between them(t = 3.94, P < 0.001). The final drainage volume was (186.3 ± 135.6) ml for one-level patients and (301.4 ± 286.8) ml for two-level patients, there were significant differences between them (t = 3.56, P < 0.05). The total intraoperative blood loss was (478.3 ± 364.3) ml and total final drainage volume was (249.2 ± 237.4) ml, there were significant differences between them(P < 0.001). There were significant differences in blood loss between autologous blood transfusion for non-transfusion groups (P < 0.001) .However, there was no difference for immediate drainage and final drainage comparing with other blood transfusion methods (P > 0.05) .
  
  
  CONCLUSIONS
  Using autologous blood transfusion alone during operation has significant difference for inoperative blood loss compared with non-transfusion. Yet there is no effect on immediate or final drainage volume.
