title: Hybrid CABG: an alternative for perfusion time decrease.
abstract: OBJECTIVE
  To evaluate the decrease of CPB time and its related complications in CABG using a hybrid alternative method.
  
  
  METHODS
  Ninety patients were retrospectively analyzed between March 2000 and August 2006. All were treated with three or more grafts and divided into two groups: Group 1 was the hybrid group--45 patients who had been operated by the hybrid technique; Group 2 was the total group--45 patients operated in on-pump.
  
  
  RESULTS
  In the hybrid group, the CPB time varied from 20 min. to 81 min. In the total group, the CPB time varied from 60 min. to 210 min. (p<0.001). The aorta cross-clamping time varied in the first group from 7 min. to 70 min. In Group 2, from 34 to 100 min. (p<0.001). A statistically significant difference was found between these two groups in relation to the occurrence of postoperative atrium fibrillation and renal dysfunction.
  
  
  CONCLUSIONS
  Using the hybrid technique it is possible to reduce the CPB time, as well as the occurrence of some postoperative complications. Probably, this decreasing in atrial fibrillation and renal dysfunction incidences could be explained due to a less significant inflammatory activation, which is a consequence of a shorter CPB time.
