treatment algorithm for allergies:
1. skin reaction, delayed onset (>60 min) = least severe
2. skin reaction, rapid onset (<60min)
3. Skin and Respiratory symptoms, trouble bleeding, airway closing off
4. anaphylaxis - multiple systems effected (Skin, GI, Respiratory, CV) = most severe
what defines an anaphylaxis allergy
Allergy affecting multiple of these systems at once:
● Skin ● GI ● Respiratory ● Cardiovascular
May not see evidence of all these systems being affected at the time, due to the rapidity of the
response.
Example: Swelling of lip -> Tx:
Oral Benadryl 50 mg, 3 to 4 times per day, for 2 to 3 days. (Children 15 to 30 kg: 25mg, same
protocol.)
