Abstract:
Epinephrine is the first line of management of anaphylaxis. Autoinjectors rapidly deliver epinephrine in anaphylaxis in the community. Patients and caregivers have safety concerns regarding their use. Accidental digital injection is a frequently encountered problem that can lead to digital ischemia. Immersion of the affected digit in warm water and topical nitroglycerine are usually used. If the symptoms persist, the patient discomfort and the possible risk of losing the digit might require an invasive approach. Local infiltration with phentolamine is mentioned in different case reports. We report a case of successful management of digital ischemia from epinephrine auto injector using phentolamine.

Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.
