Management of acute anaphylaxis

Area of Science:

• Allergy and Immunology
• Emergency Medicine
• Pharmacology

Background:

• Anaphylaxis and anaphylactoid reactions present a spectrum of clinical severity, from mild to life-threatening.
• Prompt recognition and management are crucial for patient outcomes.

Purpose of the Study:

• To outline the appropriate therapeutic interventions for anaphylactic and anaphylactoid reactions based on clinical severity.
• To emphasize the critical role of adrenaline in managing severe reactions.

Main Methods:

• Review of clinical guidelines and evidence for managing anaphylaxis.
• Categorization of treatment strategies based on reaction severity (mild, moderate, severe).

Main Results:

• Mild to moderate reactions can be managed with antihistamines and observation.
• Severe, life-threatening reactions necessitate the immediate administration of adrenaline.
• Adjunctive therapies include intravenous fluids, beta-2 agonists, and respiratory support (intubation/ventilation).

Conclusions:

• Adrenaline is the cornerstone of treatment for severe anaphylaxis and must not be substituted.
• Antihistamines and corticosteroids may play a supportive role but are secondary to adrenaline.
• Timely and appropriate intervention based on reaction severity is essential for preventing mortality.
