title: [Contribution of central venous oxygen saturation in postoperative blood transfusion decision].
abstract: OBJECTIVE
  The aim of this study was to assess the value of central venous oxygen saturation (ScvO(2)) for the decision of blood transfusion in comparison with the criteria of the French guidelines for blood transfusion (2003).
  
  
  METHODS
  Prospective, observational.
  
  
  METHODS
  Sixty patients, haemodynamically stable, for whom a blood transfusion (BT) was discussed in the postoperative course of general surgery, were included. ScvO(2) (%) and haemoglobin (g/dl) were measured before and after BT. Patients were retrospectively divided into two groups according to ScvO(2) measured before BT (< or >or=70%). Results are expressed as median.
  
  
  RESULTS
  The ScvO(2) before transfusion was greater or equal to 70% in 25 (47.2%) patients. Following BT, the ScvO(2) increased significantly (from 57.8 to 68.5%) in the group with initial ScvO(2) less than 70% whereas it was unchanged in patients with initial ScvO(2) greater or equal 70% (from 76.8 to 76.5%). Twenty patients (37.7%) did not meet the French guidelines for BT criteria. Eighteen patients out of 33 that met the criteria had ScvO(2) greater or equal 70% before BT while 13 patients with ScvO(2) less than 70% were not detected by these same criteria.
  
  
  CONCLUSIONS
  ScvO(2) could be a relevant biological parameter to complete the current guidelines for BT in stable patient with a central venous catheter during the postoperative period.
