title: Prediction of survival after 48-h of intensive care following open surgical repair of ruptured abdominal aortic aneurysm.
abstract: OBJECTIVE
  To identify predictive factors for 30-day mortality after 48 h of maximal treatment in intensive care unit (ICU) after repair for ruptured abdominal aortic aneurysm (RAAA).
  
  
  METHODS
  Retrospective study in the ICU of the university central hospital.
  
  
  METHODS
  Between 1999 and 2003, a total of 197 patients were admitted to emergency unit due to RAAA, and 185 of them underwent open surgical repair. A total of 138 patients survived at least 48-h and were included in a study to identify factors predictive of 30-day mortality by logistic regression analysis.
  
  
  RESULTS
  Thirty-day mortality of all RAAA patients was 46% (87/197) whereas the 30-day mortality for those alive at 48 h was 22% (31/138). Forward stepwise multivariate logistic regression analysis revealed that only organ dysfunction by SOFA score (sequential organ failure assessment) at 48-h, preoperative Glasgow Aneurysm Score, and supra-renal clamping in operation were independent predictors of death.
  
  
  CONCLUSIONS
  Degree of organ dysfunction by SOFA score was the best predictor of 30-day mortality in RAAA patients alive at 48-h after open surgical repair.
