Following ROSC after cardiac arrest, the clinicians are responsible for determining the patient’s neurological status. The team must understand the assessments that will aid in developing a realistic prognosis for the patient.
The team uses multiple modalities in this process:

Neuroprognostication Modalities
- Clinical Assessment begins at the time of ROSC and continues throughout the patient’s stay. The assessments include:
- Targeted temperature management (TTM), beginning at ROSC and continuing for approximately 36 hours.
- After TTM, the team begins rewarming the patient. This process continues until 60 hours following ROSC.
- At that time, the team ensures normothermia and begins to reduce sedation
- Radiological Assessment includes:
- CT of the head at the time of ROSC and as needed for 24 hours.
- After 24 hours, MRI is a better tool for predicting neurological outcomes.
- Electrophysiological Assessment includes:
- Assessment of SSEP N20 cortical waves beginning at 24 hours after ROSC.
- Burst suppression and status epilepticus assessment beginning at 72 hours after ROSC.
- Clinical Examination includes:
- Continual EEG assessment for status myoclonus beginning at 24 hours after ROSC.
- Assessment of pupillary light reflex, pupillometry, and corneal reflex beginning at 72 hours after ROSC.
- Serum Biomarker Assessment includes assessment for serum neuron-specific enzyme (NSE) at 24 hours after ROSC.
