Which of the following is NOT part of the immediate management of anaphylaxis?

In the context of anaphylaxis management, sending a patient home after the first dose of adrenaline is not advisable and is, therefore, not part of the immediate management protocol. Anaphylaxis is a severe, potentially life-threatening allergic reaction that requires careful monitoring and treatment.

When a patient experiences anaphylaxis and is administered intramuscular (IM) adrenaline, it is critical that they are observed in a medical setting for at least several hours, usually for a minimum of 4-8 hours after the initial dose. This is due to the risk of biphasic anaphylaxis, where symptoms can return after the initial episode has resolved. Immediate follow-up care involves monitoring for respiratory distress, cardiovascular stability, and any further reactions.

Administering high-flow oxygen and providing IV fluids may also be necessary depending on the severity of the reactions and the patient's vital signs, but these interventions are aimed at supporting the patient during the acute event. Ultimately, the patient's safety necessitates that they are not sent home immediately after treatment but rather monitored for further development of symptoms before discharge.
