Guidelines recommend use of computerized tomography (CT) and electroencephalography (EEG) in post-arrest prognostication. Strong associations between CT and EEG might obviate the need to acquire both modalities. We quantified these associations via deep learning. ⋯ CT and EEG provide complementary information about post-arrest brain injury. Our results do not support selective acquisition of only one of these modalities, except in the most severely injured patients.

Point-of-care ultrasound (POCUS) is used in cardiac arrest patients to assess for reversible causes. We aimed to conduct a diagnostic test accuracy systematic review of intra-arrest POCUS to indicate the etiology of cardiac arrest in adults in any setting. ⋯ It is feasible to identify reversible causes of cardiac arrest with POCUS, but the current literature is heterogenous with high risks of bias, wide confidence intervals, and very low certainty of evidence, which render these data difficult to interpret.
