Background: Good neurological outcome is a major determinant after cardiac resuscitation. Extracorporeal life support may rapidly stabilize the patient, but cerebral ischemia remains a frequent complication relevant for further therapy. The aim of this study was to prove the value of NSE to indicate cerebral injury in patients with extracorporeal support after CPR. Methods: 159 patients with CPR were included. NSE 48 h peak levels and trends were tested for usability as predictive marker of brain injury, in-hospital mortality and long-term outcome. Results: Overall mortality in this cohort was 53.5%. Incidence of relevant brain injury was 34.6% with severe diffuse hypoxia in 23.2%. NSE peaks were comparable in patients with and without focal ischemia, but were increased in patients with severe diffuse hypoxic injury (p < 0.0001). ROC analysis (area under the curve) of peak values indicating brain injury and in-hospital mortality was 0.73 (95% confidence interval [CI] 0.65-0.82) and 0.74 (95% CI 0.66-0.81), respectively. NSE increased in 56.6% of patients with a sensitivity of 0.82 (95% CI 0.69-0.92) and a specificity of 0.43 (CI 0.0.31-0.55) indicating cerebral injury. Sensitivity and specificity of NSE peak levels > 100 mu g/L was 0.6 (CI 0.49-0.72) and 0.74 (CI 0.63-0.84). In-hospital mortality of patients with NSE > 100 mu g/L was 71.7%. 46.2% of discharged patients are in good neurological status (cerebral performance category scale [CPC] 1-2). Patients with NSE < 100 mu g/L showed an in-hospital mortality of 36.4%, and good neurological status in 67.9%. Conclusion: NSE monitoring reliably indicates relevant cerebral injury in patients on extracorporeal support after cardiopulmonary resuscitation. (C) 2017 Elsevier B.V. All rights reserved.
