A case of atypical status epilepticus is reported in which convulsive spasms were slight and tended selectively to affect muscles associated with respiration with the result that cyanosis was deeper than the degree observed in ordinary status epilepticus. Status epilepticus occurs infrequently, it may be atypical and difficult to recognize. Fatal cases have been reported. On this occasion it was amenable to treatment. Its occurrence bears no relation to the size of the dose of metrazol used. In the cases reported it has followed the first administration of the convulsive agent.Abstract Teaser
