Neurological evolution of patients in coma at 72 hours after out-of-hospital cardiac arrest

Abstract Introduction Establishing neurological prognosis after out-of-hospital cardiac arrest (OHCA) safely and early in those patients who remain a coma at 72 hours of admission. Purpose To analyze the prognostic performance neuron-specific enolase (NSE), Somatosensory evoked potentials (SSEPs) electroencephalogram (EEG) these patients. Methods Prospective observational study, including all OHCAs admitted to Cardiovascular Intensive Care Unit (CICU) tertiary hospital. Neurological stratification was performed with NSE (poor >60 ng/mL), SSEP absence N20) EEG prognosis). The sensitivity specificity each test for poor were calculated, as well three tests together. Results Between 03/17/2013 02/24/2022, 422 registered, which 170 remained hours. had 84% 89% due prognosis. SSEPs 68% 98% 67% 100% able be on 110 patients, combined 49% 100%. Conclusions In OHCA, most specific establish sensitive EEG. combination Funding Acknowledgement Type funding sources: None.
