What is the first priority when treating a patient with a severe allergic reaction?

When addressing a patient experiencing a severe allergic reaction, often referred to as an anaphylactic reaction, the first priority is to maintain airway patency and administer epinephrine. This is essential because a severe allergic reaction can lead to significant airway swelling and obstruction, as well as a drop in blood pressure and potential cardiovascular collapse.

Epinephrine is a critical medication in this context; it works swiftly to counteract the effects of the allergic reaction by causing vasoconstriction, bronchodilation, and reducing vascular permeability. This, in turn, helps to stabilize the patient’s condition by improving airflow and reducing swelling in the airways. Ensuring that the airway is clear and providing immediate epinephrine significantly enhances the likelihood of a positive outcome.

While administering antihistamines and providing oxygen therapy are important in managing allergic reactions, they are not the first steps. Antihistamines act more slowly and are not effective in treating life-threatening symptoms of anaphylaxis, such as airway obstruction. Transporting the patient to the hospital is also essential, but it follows the immediate need to stabilize the patient’s condition with airway management and epinephrine administration. Immediate actions addressing airway and circulation take precedence in acute care scenarios.
