A patient with myasthenia gravis, being treated with atropine and neostigmine, is brought to the emergency room.
He is cyanotic, has weak respiratory movements, poor grip strength and other signs of striated muscle weakness.
A test injection of edrophonium caused a temporary intensification of these symptoms.
It, therefore, can be concluded that this patient has
a) a cholinergic crises
b) a myasthenic crises
c) atypical pseudocholinesterase syndrome
d) botulism
e) atropine toxicity
