HypothesisOutcomes of critically ill patients who receive cardiopulmonary resuscitation (CPR) are poor, and the subgroup on vasopressors or inotropes before cardiopulmonary arrest (CPA) rarely survives.SettingThe setting of the study was a critical care unit of a 350-bed community teaching hospital.Study DesignThis was a retrospective, cohort study.MethodsA retrospective review was performed of medical records of all patients, identified through medical billing and hospital committee records, who received CPR for CPA in a critical care unit.ResultsOf 83 patients, with an average age of 66 years, 14 (17%) survived to hospital discharge. Patients with pulseless electrical activity and asystole were significantly less likely to survive (9% and none, respectively; P = .0001). Only 2 (4%) of 55 critically ill patients receiving vasopressors before CPR survived, whereas 12 of 28 patients not on vasopressors survived (P < .0001). Although mechanical ventilation just before CPR was highly associated with administration of vasopressors, ventilation was not significantly associated with mortality (P = .13). Mortality of patients on vasopressors was higher for both mechanically ventilated (95% vs 33%, P < .001) and spontaneously breathing (100% vs 64%, P = .02) patients. In multiple logistic regression analyses, administration of vasopressors was the only variable independently associated with in-hospital mortality (odds ratio, 35.1; 95% confidence interval = 4.1-304.3).ConclusionsSurvival of patients requiring CPR during critical care admission was 17%. Very few patients survived who required vasopressors or inotropes immediately before CPA. This study is limited significantly by its retrospective design and small cohort, and so this question should be reexamined in a larger study.
