title: [Cause analysis of prolonged intensive care unit stay after coronary artery bypass grafting].
abstract: OBJECTIVE
  To investigate the risk factors of prolonged intensive care unit (ICU) stay following coronary artery bypass grafting (CABG), and to provide a reference for effective control measure.
  
  
  METHODS
  A retrospective study was conducted. All data of patients with post CABG admitted to the Department of Critical Care Medicine of the First People's Hospital in Yichang from January 2008 to January 2012 were retrospectively analyzed. The CABG patients staying in ICU more than 3 days served as observation group, and the patients staying in ICU less than 3 days were the control group. Potential risk factors in both groups were compared, and multivariable non-condition logistic regressions analysis was adopted to determine the independent risk factors which resulted in prolonged stay in ICU after CABG.
  
  
  RESULTS
  Sixty-eight patients underwent CABG were analyzed retrospectively. Twenty-four cases (35.29%) had prolonged stay in ICU after CABG. Univariate analysis showed that the risk factors of prolonged stay in ICU after CABG were low cardiac output, arrhythmia, postoperative respiratory failure, postoperative acute renal failure, emergency operation, and left atrial inner diameter. The multivariable logistic regression analysis showed that the independent risk factor of prolonged stay in ICU after CABG was the postoperative respiratory failure [odds ratio (OR)=6.856, 95% confidence interval (95%CI) 1.322 - 35.559, P<0.05].
  
  
  CONCLUSIONS
  The independent risk factor of prolonged stay in ICU after CABG was postoperative respiratory failure. By monitoring the risk factors, duration of stay in ICU after CABG can be decreased.
