ABSTRACT

Background: For coronary artery bypass graft (CABG) surgery, cardiopulmonary bypass (CPB) is required for many patients. However, this procedure has several risks. Our objective was to test the hypothesis that minimal extracorporeal circulation is more advantageous than conventional CPB for CABG surgery.
Methods: We analyzed 17 patients submitted to CABG surgery between April 1, 2006 and August 31, 2009. Patients were divided into two groups. In one group, minimal extracorporeal circulation system (MECC) (n = 8) was used and in the other group the conventional CPB circuit (n = 9). Perioperative bleeding, blood requirements and clinical evolution were compared.
Results: We observed a statistically significant difference for postoperative leukocyte count (p ‹0.05). However, for blood requirements, intraoperative urinary output, and pre- and postsurgical levels of creatinine, we did not find differences. Intraoperative bleeding was lower in the MECC group (p ‹0.05). Major cardiovascular complications were also lower in this group (p ‹0.05).
Conclusions: It was concluded that MECC reduces the frequency of major cardiovascular complications, intraoperative bleeding and probably a lower inflammatory systemic response compared with conventional CPB.
