Autonomic Storm
Definition
The biphasic cardiovascular crisis of Indian red scorpion envenomation. An initial cholinergic phase of vomiting, salivation and bradycardia is followed by an adrenergic phase of hypertension, tachycardia, pulmonary oedema and myocarditis. The Bawaskar protocol uses prazosin to block the adrenergic surge.
