RESPONSE TO PAINFUL STIMULI


Profound sedation in the presence of a reasonable blood pressure suggests TCAs, neuroleptics, anticonvulsants (e.g. carbamazepine, phenytoin), opioids or barbiturates.

It is unusual for benzodiazepines or alcohol alone to lead to deep coma (grades 2-4). More serious toxins such as TCAs and anticonvulsants are more likely.
