Episode notes
Strict Criteria Define Anaphylaxis
- Anaphylaxis diagnostic criteria depend on skin involvement plus respiratory or blood pressure symptoms, or two systems affected after allergen exposure.
- These criteria are strict; some patients may need epinephrine even if they don't strictly meet definition.
Epinephrine's Multifaceted Action
- Epinephrine quickly reverses the cardiovascular, respiratory, and gastrointestinal effects of anaphylaxis.
- It also stabilizes mast cells, preventing further release of histamines and immune mediators.
Watch for Any Rapid Rash
- Don’t require families to distinguish between hives and other rashes; any rapid-onset, widespread rash should raise suspicion.
- Erythroderma or diffuse flushing is an especially important early signal of potential anaphylaxis.
