title: [Analysis of risk factors of postoperative hemodialysis in patients undergoing off-pump coronary artery bypass grafting].
abstract: OBJECTIVE
  To investigate the risk factors of postoperative hemodialysis in patients undergoing off-pump coronary artery bypass grafting (OPCAB).
  
  
  METHODS
  The perioperative data of 2379 consecutive patients undergoing OPCAB from November 2007 to February 2009 were analyzed retrospectively. Patients were divided into dialysis group and non-dialysis group according to their use of hemodialysis therapy or not.
  
  
  RESULTS
  Fifty-four patients experienced hemodialysis postoperatively. The incidence of hemodialysis was 2.3%, the mortality rate of dialysis group and non-dialysis group was 18.5% and 0.9% respectively. Univariate analysis showed that these factors significantly related with the postoperative dialysis:intraoperative ventricular fibrillation, emergent cardiopulmonary bypass, preoperative atrial fibrillation, intraoperative atrial fibrillation, preoperative renal dysfunction, intraoperative high-dose adrenaline usage, ventricular aneurysm, combined valvular disease, hypertension, age and numbers of grafting vessels. Multivariate logistic regression showed that intraoperative ventricular fibrillation, intraoperative high-dose adrenaline usage, hypertension, age and the numbers of grafting vessel were the risk factors of postoperative hemodialysis for patients undergoing OPCAB surgery.
  
  
  CONCLUSIONS
  Intraoperative ventricular fibrillation, intraoperative high-dose adrenaline usage, hypertension, age and the numbers of grafting vessels were the independent predictors of postoperative hemodialysis in patients undergoing OPCAB surgery.
