Abstract:
A 51-year-old man suffered a cardiac arrest after an attempted hanging. Post-arrest assessment revealed the bilateral absence of negative 20 somatosensory evoked potentials (N20 SSEPs) which is suggestive of a poor neurological outcome. Current evidence recommends its use in prognostication. Our patient made a good recovery which brings into question the value of negative 20 somatosensory evoked potentials in prognostication with concomitant neck injuries and swelling.
