Comparison of three blood-processing techniques during and after cardiopulmonary bypass

摘要: The return of extracorporeal circuit blood at the termination cardiopulmonary bypass is an important feature conservation during open heart procedures. However, relative benefits and disadvantages different salvage methods remain unclear. Accordingly, purpose this study was to examine whether quantifiable differences exist between three blood-salvaging techniques: direct infusion, centrifugation, ultrafiltration. Sixty patients with very similar preoperative characteristics were randomly assigned each groups, coagulation screens, plasma profiles, respiratory function determined 20 minutes 6 18 hours after bypass. Early (20 minutes), colloid osmotic pressure fibrinogen platelet concentrations significantly higher ultrafiltration (p < 0.05) versus those observed for other two methods. thromboplastin times longer centrifugation as compared infusion profiles composition normalized by all There no significant in terms utilization or chest tube drainage over entire postoperative period among any These results suggest that postcardiopulmonary may preserve concentration early period, but these do not persist. Thus, routine procedures, be satisfactory salvage.
