Flashcards in Allergic Reaction Deck (12):

What is one of the most critical components when differentiating between allergic reaction and anaphylaxis

*any involvement in respiratory (wheezing/stridor) or oral/facial edema should be treated as anaphylaxis.


Key tx for allergic reaction that presents with stable vitals with a rash, hives.

Remove stinger
-Benadryl 50 mg PO/IV/IM


Anaphylaxis ALS treatment

Epi 0.3mg 1:1000 IM
Benadryl 50mg IV/IM/IO
Albuterol 2.5mg (3ml) if wheezing present
Consider CPAP
Contact base for IV Epi - 0.1 mg1:10,000 IV push


In extreme anaphylaxis you may consider IV Epi
A) Epi dose and concentration
B) When to epi admin

**Base Hospital Order Only**

A)Epi 0.1 mg increments of 1:10,000 slow IV push, for stridor and hypotension until a SBP >90 or a total of 0.5mg given


Allergic Reaction Definition

A local response to an antigen involving the skin (rash, hives, edema, etc) with normal vital signs. Any involvement of the respiratory system (wheezing, stridor, or oral/facial edema will be treated as anaphylaxis. remember that allergic reactions may deteriorate into anaphylaxis reassess often and be you prepared to treat for anaphylaxis


Anaphylaxis definition

The systemic response to an antigen involving two or more organ systems or any involvement of the upper and/or lower respiratory systems or any derangement of vital signs


Allergic Reaction/Anaphylaxis - BLS

O2 SpO2>94%. Use lowest concentration

Airway adjunct as needed

Remove sting/injection mechanism

Transport and begin therapy simultaneously


Allergic reaction ALS

Diphenhydramine Benadryl
50 mg PO/IV or IM


Anaphylaxis BLS

Oxygen adjust just flow and delivery mode as needed

Airway adjunct as needed

Remove sting/injection mechanism

Assist patient in the use of patient prescribed medication including autoinjectors

Transport and begin therapy simultaneously


Anaphylaxis ALS

Establish large bore IV access with normal saline, titrate to a systolic blood pressure of 90 - 100 mmHG

Epinephrine 0.3 mg of 1:1000 IM

Diphenhydramine Benadryl 50 mg IV/IM or I/O

ECG and SPO2 monitoring

Albuterol 2.5 mg 3 mL unit does HHN for wheezing. Reassess after first treatment, may be repeated as needed based on reassessment


0.1 mg increments of 1 to 10,000, slow IV push, for stridor and hypotension, until a systolic blood pressure greater than 90 him mmHG or a total of 0.5 mg is given


Allergic Reaction/Anaphylaxis - Can you repeat Diphenhydramine and epi IM?

Does not say in protocol- Would need base contact


Allergic Reaction/Anaphylaxis - Albuterol
When to use
How many times can you repeat

Repeat as needed
