When is the ideal time to administer IM adrenaline in anaphylaxis?

• A. After fluid resuscitation
• B. Immediately upon recognition of anaphylaxis
• C. Once cardiovascular stability is achieved
• D. Following antihistamine administration

Answer: (B)

Administering intramuscular adrenaline immediately upon recognition of anaphylaxis is crucial for effective treatment. Anaphylaxis is a life-threatening allergic reaction that can progress rapidly, leading to severe respiratory distress, cardiovascular collapse, and even death. The sooner adrenaline is given, the better the chance of reversing the symptoms, as it works by constricting blood vessels, dilating the airways, and increasing heart rate, all of which counteract the severe effects of anaphylaxis. The immediate administration of adrenaline allows for rapid absorption and action, which is vital since reactions can escalate within minutes. Delaying this treatment for fluid resuscitation, achieving cardiovascular stability, or waiting until after antihistamines are administered could jeopardize the patient's life, as these alternatives do not address the acute symptoms of anaphylaxis as effectively or as quickly as adrenaline does.
