摘要: Abstract Objective To analyze the association between SSEP results and EEG in comatose patients after cardiac arrest, including added value of repeated measurements. Methods Continuous was measured 619 during first 3–5 days arrest. SSEPs were recorded daily 55 patients, on indication later patients. EEGs visually classified at 12, 24, 48, 72 h time SSEP. Outcome 6 m dichotomized as good (Cerebral Performance Category 1–2) or poor (CPC 3–5). related to outcome. Additionally, patterns Results Absent responses suppressed synchronous background ≥24 h arrest invariably associated with identified different outcome (joint sensitivity 39% specificity 100%). N20 always preserved continuous traces >8 Hz. did not re-emerge five days. Conclusions may diverge Significance together identify more without chance recovery than one these alone.
