A reliable and reproducible method for precisely predicting the neurological outcome of patients with hypoxic-ischemic encephalopathy after cardiac arrest is urgently needed in neurological intensive care units. We prospectively investigated the predictive power of serum concentrations of neuron-specific enolase (NSE) and protein S-100B (S-100B) measured on days 1, 2, 3 and 7 as well as somatosensory-evoked potentials (SEPs) recorded within 48 h and on day 7 after cardiopulmonary resuscitation (CPR) in 27 patients (14 females, 13 males; mean age 61.3 +/- 17.3 years) with hypoxic-ischemic encephalopathy. During the first 7 days after CPR, median values of NSE and S-100B were increased in patients who remained unconscious after CPR compared to those patients who regained consciousness (significance up to less than or equal to0.001). The best predictor of negative outcome was an NSE cutoff point greater than or equal to43 mug/l on day 2; this had a sensitivity of 90.9% and a specificity of 100%. Additional use of S-100B on day 2 did not increase sensitivity, but this could be markedly increased by combining NSE and S-100B on days 1, 3 and 7. SEPs showing bilateral loss of cortical responses identified patients who did not regain consciousness with a specificity of 100%. Copyright (C) 2003 S. Karger AG, Basel.
