학습 자료 둘러보기 →In anaphylaxis with hypotension and stridor, the priority is epinephrine 1:1000 0.3-0.5 mg IM into the anterolateral thigh. This is the only agent that simultaneously reverses vasodilation, bronchoconstriction, and airway edema.
Delayed epinephrine administration is the primary cause of fatal outcomes. Do not prioritize adjuncts like oxygen, fluids, or intubation preparation over the first-line pharmacological intervention.
In severe shock, intravenous epinephrine requires cardiac monitoring and is reserved for patients unresponsive to multiple IM doses. The initial dose must be given IM without delay.
