Abstract

Objective: To assess a new technique of hemoconcentration and the necessity of blood component transfusion.Method: Eighty-six male (61.4%) and 54 female (38.6%) patients submitted to heart surgery under cardiopulmonary bypass were divided into two groups of 70 patients each according to conventional technique of blood preparation (Group A) and the use of the new technique of hemoconcentration (Group B).Results: The hemoconcentration technique is feasible and did not alter the intra-and postoperative complications of the patients. The amount of blood and plasma used during and after cardiopulmonary bypass was less in Group B patients. Moreover, the fluid balance after cardiopulmonary bypass in this group was better when compared to the Group A patients. Conclusions:The new technique of hemoconcentration was efficient regarding removal of fluids, allowed a better use of oxygenator residual contents and decreased the amount of blood components used during and after cardiopulmonary bypass.

Preditores de transfusão de concentrado de hemácias em cirurgia de revascularização miocárdica

“…Souza & Braile [25] developed a study to evaluate a technique of hemoconcentration during heart surgery with CPB with and without a hemoconcentrator and the necessity of blood components transfusion in patients. They verifyed that this technique of hemoconcentration used during on-pump heart surgery was efficacious in the removal of fluids and allowed a greater utilization of the blood remaining in the oxygenator and a lesser necessity of blood component transfusion.…”

“…Studies conducted on the use of hemoconcentration in cardiac surgery with ECC have concluded that the main advantages are removal of the macromolecules that mediate the systemic inflammatory reaction, reduction of circulating endotoxins, elimination of excess body water and pulmonary hypertension 15,16 .…”
