List the clinical signs and tests used for neuro-prognostication after cardiac arrest and discuss their limitations.
The question did not ask for "advantages and disadvantages", they only wanted limitations. Thus, a mangled truncated version of summary the table from the neuroprognostication chapter is offered here.
|Predictive sign or investigation||Limitations and confounding factors|
|Absent pupillary reflex||
|Absent corneal reflex|
|Extensor motor response, or worse||
|Myoclonic status epilepticus||
|Somatosensory evoked potentials:
absence of the N20 component
|Burst suppression on EEG||
|Absence of EEG reactivity, or "malignant" EEG pattern||
