who then are found to have no detectable abnormality on post-mortem. Management is therefore to provide oxygen and to abolish the inappropriate muscular activity. Airway control by ET intubation and the accompanying paralysis will abort the muscle activity. Why then does tonic-clonic seizure activity not also lead to sudden death? Well, in the community it can do if unchecked. Most seizures are self-limiting, but status is dangerous. The muscle activity is usually less in seizures than in hyperexcitable states as well. So I end this little paper (which I am publishing formally) with a request. If any of the group get a patient with such a state please measure the gases before (or maybe immediately after) intubation to see if this is reproducible - a case report is less useful than a series!
