Anaphylaxis: Emergency Department Treatment.

Area of Science:

• Allergy and Immunology
• Emergency Medicine
• Critical Care Medicine

Background:

• Anaphylaxis is a severe, multisystem allergic reaction.
• It can lead to life-threatening airway, breathing, or circulatory compromise.
• Prompt and appropriate management is critical for patient survival.

Purpose of the Study:

• To outline the immediate management of anaphylaxis.
• To detail treatment strategies for anaphylactic shock.
• To provide guidance on patient disposition after anaphylaxis.

Main Methods:

• Review of current anaphylaxis treatment guidelines.
• Emphasis on immediate intramuscular epinephrine administration.
• Discussion of advanced interventions including intravenous epinephrine, fluid resuscitation, airway management, and vasopressors.

Main Results:

• Intramuscular epinephrine is the first-line treatment for all anaphylaxis patients.
• Intravenous epinephrine, fluid resuscitation, and airway support are indicated for patients in shock.
• Vasopressors may be required for epinephrine-refractory shock.

Conclusions:

• Anaphylaxis requires immediate intervention with epinephrine.
• Management should be tailored to the patient's presentation, including airway and circulatory status.
• Mandatory observation periods are not recommended due to the unpredictable nature of biphasic reactions.
