Outpatient Specialty Care and Primary Care Clinical Pathway for Evaluation/Treatment of Children with Anaphylaxis

Patients > 5 kg with Suspected Anaphylaxis
Providers: Use individual clinical decision for infants < 5 kg
Anaphylaxis is highly likely when ONE of the following 3 criteria are fulfilled within minutes to 2-3 hours following possible allergen exposure
CRITERIA 1

Acute onset of an illness with involvement of the skin, mucosal tissue, or both
(e.g., generalized hives, pruritis or flushing, swollen lip-tongue-uvula)

AND AT LEAST ONE OF THE FOLLOWING
  • Respiratory compromise
  • Reduced BP or associated symptoms of end-organ dysfunction
  • Persistent gastrointestinal symptoms
  • Significant abdominal pain and/or significant vomiting
CRITERIA 2

Two or more of the following that occur rapidly after exposure to a LIKELY ALLERGEN for that patient:

  • Involvement of the skin-mucosal tissue
  • Respiratory compromise
  • Reduced BP or associated symptoms
  • Persistent gastrointestinal symptoms
CRITERIA 3 Reduced BP after exposure to KNOWN ALLERGEN for that patient
  • Epinephrine treats all symptoms of anaphylaxis and can prevent the escalation of symptoms.
  • IM is preferred, being faster and safer.
  • Use of adjunctive medications should not delay epinephrine administration.
Epinephrine Dosing - IM
5 - 25 kg 0.15 mg EpiPen Jr®
> 25 kg 0.3 mg EpiPen®

Risk Factors for Biphasic Reaction

  • History of biphasic or severe reactions
  • Progression of / or persistent symptoms
  • History of severe asthma
  • Hypotension
  • Requires > 1 Epinephrine dose
  • Requires fluid bolus
  • Drug trigger

Severe Symptoms

  • Upper airway obstruction
  • Lower airway symptoms
  • Circulatory abnormality
 
  • Consider the use of the following medications:
    • Albuterol
    • Antihistamines
    • Steroids
    • Racemic Epi
  • Above medications are available in
    BLS carts
  • Initial Assessment
  • If meets criteria for anaphylaxis:
  • ADMINISTER EPINEPHRINE IM IMMEDIATELY
  • Repeat Epi dose q 5-15 minutes prn as clinically indicated:
    • Signs of upper airway obstruction
    • Continued respiratory distress/bronchospasm
    • Poor perfusion or hypotension
    • Persistent GI symptoms
  • INITIATE APPROPRIATE EMERGENCY RESPONSE
  • Clinics Outside of Main Campus
    • ACTIVATE EMERGENCY RESPONSE
      CALL 911
  • Buerger Center
    • CALL CODE BLUE - EXT. 4-2633
      or 4-CODE
  • Initiate Basic Life Support
  • History, physical exam
Assess, Manage ABCs
Mental status Oxygen
Upper airway obstruction Racemic epinephrine
(should not replace Epi IM)
Lower airway symptoms Albuterol
Circulatory abnormality Trendelenburg position
IV, NS if able
