What is the immediate management for anaphylaxis during anesthesia?

In the context of managing anaphylaxis during anesthesia, the immediate administration of epinephrine is the cornerstone of treatment. Anaphylaxis is a severe, systemic allergic reaction that can quickly lead to respiratory distress, cardiovascular collapse, and other life-threatening complications. Epinephrine acts as a potent vasoconstrictor and bronchodilator, rapidly reversing the effects of anaphylaxis by increasing blood pressure, improving airway patency, and enhancing cardiac output.

When anaphylaxis is suspected or recognized during surgical procedures, the timely administration of epinephrine is crucial, as delaying treatment can significantly worsen the patient’s condition. The standard dose is typically 0.3 to 0.5 mg of intramuscular epinephrine, but in some cases, intravenous administration may be necessary, especially if the patient is in severe shock.

Other management steps, such as administering antihistamines, starting IV fluid resuscitation, or immediate intubation, may be part of the overall treatment strategy, but they do not replace the importance of epinephrine as the first-line therapy. Antihistamines may help with allergic symptoms but do not address the potentially life-threatening aspects of anaphylaxis. Similarly, IV fluid resuscitation is important for
