What is the typical immediate management for intraoperative anaphylaxis?

• A. Epinephrine administration with fluids and removal of the trigger.
• B. Raise the inhaled anesthetic concentration.
• C. Stop all medications and wait.
• D. Give antihistamines alone.

Answer: (A)

Prompt recognition and prompt treatment with epinephrine are essential because intraoperative anaphylaxis causes life-threatening hypotension, airway edema, and bronchospasm. Epinephrine acts on multiple receptors to reverse these problems: alpha-1 constricts dilated vessels to raise blood pressure and reduce edema, beta-1 boosts cardiac output, and beta-2 relaxes bronchial smooth muscle and dampens mediator release. Giving a carefully titrated IV dose quickly during the event, along with aggressive IV fluids to support circulation, addresses the core physiologic derangements. Removing the trigger—such as stopping the suspected drug or other inciting agent—and calling for help are critical to halt ongoing exposure and further mediator release. Providing high-flow oxygen and preparing for airway management if edema or obstruction progresses completes the immediate resuscitation. Raising the inhaled anesthetic concentration wouldn’t address the shock and could worsen hemodynamics. Stopping all medications and waiting delays lifesaving treatment. Antihistamines alone don’t treat the shock and bronchospasm seen in anaphylaxis and are not sufficient as the sole therapy.
