title: [Strategies to reduce the use of blood components in cardiovascular surgery].
abstract: OBJECTIVE
  The aim of this study is to evaluate the strategies adopted by our team to reduce the use of bloods components in patients undergoing cardiovascular surgical procedures.
  
  
  METHODS
  Between October 2005 and January 2007, 101 patients were operated. Fifty-one (50.5%) were male and 50 (49.5%) female. Patients' age ranged from 13 to 80 years (mean of 50.76 years). The strategy consisted in using antifibrinolytics and normovolemic hemodilution, and reinfusion of all the blood remaining in the CPB circuit.
  
  
  RESULTS
  Mean use of blood components was 1.45 UI, red blood cells; 0.75 UI, fresh frozen plasma; 0.89 UI, cryoprecipitate, and 1.43 UI, platelet. Fifty-nine patients (58.4%) had not used blood components and 12 (11.9%) patients used more than 4 UI of red blood cells. In 27 patients (26.7%) whose CPB time was higher than 120 minutes, 17 (63%) needed hemotransfusion. However, 3 (2.97%) developed coagulopathy and 2 (1.98%) needed reoperation due to bleeding. Of the three patients who developed coagulopathy, two were in the elderly subgroup.
  
  
  CONCLUSIONS
  In the presented series, the measures adopted succeeded in reducing the need of hemotransfusion in the postoperative period of thoracic surgery. Patients with CPB time higher than 120 minutes tended to need hemotransfusion. The association of surgery in elderly patients and CPB time over 120 minutes resulted in significantly greater use of blood components postoperatively.
