BackgroundPost-arrest variables associated with long-term survival after cardiopulmonary resuscitation (CPR) in intensive care unit (ICU) patients remain unclear. This study was designed to identify pre- and intra-arrest factors associated with survival 3 months after CPR in ICU patients and to identify post-arrest factors associated with long-term survival in those who survived 24 h after CPR.MethodsA total of 131 ICU patients undergoing CPR from January 2009 to June 2010 were included. Data were retrospectively analysed and categorized based on the Utstein template.ResultsThe overall survival rate 3 months after CPR was 20.6%. Logistic regression analysis revealed that acute physiology and chronic health evaluation (APACHE) II score (odds ratio, 95% confidence interval, 0.87 [0.83-0.93]; P < 0.001), ventricular tachycardia/ventricular fibrillation (VT/VF, 5.55 [1.55-19.83]; P = 0.032), and normoxia during CPR (4.45 [1.34-14.71]; P = 0.045) were significant independent pre- and intra-arrest predictors of 3-month survival after CPR in ICU patients. Fifty-seven patients survived 24 h after CPR, and their 3-month survival rate was 47.4%. Early enteral nutrition (9.94 [1.96-50.43]; P = 0.030) and normoxia after return of spontaneous circulation (10.75 [2.03-55.56]; P = 0.030) were predictive of 3-month survival in patients who survived 24 h after CPR.ConclusionsNormoxia during CPR and VT/VF were predictors of long-term survival after CPR in ICU patients. In patients surviving 24 h after CPR, initiation of enteral nutrition within 48 h and maintenance of normoxia were associated with a positive outcome.© 2013 The Acta Anaesthesiologica Scandinavica Foundation.
