Answer

The ERC guidelines indicate that poor outcome is very likely in patients who are unconscious for 72 hours or more after ROSC and have one or both of the following [49] :

  • No pupillary and corneal reflexes

  • Bilaterally absent N20 somatosensory-evoked potential (SSEP) wave

If neither of those are present, the ERC recommends waiting at least 24 hours. At that point, poor outcome is very likely in patients with two or more of the following:

  • Status myoclonus 48 hours or less after ROSC

  • High neuron-specific enolase

  • Status epilepticus on EEG

  • Diffuse anoxic injury on brain CT/MRI
