Allergic Reaction or Anaphylaxis

Algorithm

New UPDATED 10/1/2019

Standing Orders:  Allergic reactions can be mild or severe (anaphylaxis), treat based on the following assessment findings:

 

Allergic Reaction Includes: 

(rash, urticaria, and vital signs stable)

→ Pulse oximetry, if SPO2 less than 95%

High flow oxygen by mask as tolerated

 

Allergic Reaction Includes: 

(facial/cervical angio-edema):

Epinephrine 0.01 mg/kg IM Lateral Thigh area (1 mg/mL), once (Max of 0.5 mg)

(Do not administer if Epi pen given prior to arrival)

Diphenhydramine 1 mg/kg IM/IV/IO once, (Max of 40 mg or 0.8 mL of 50 mg solution)

(Do not administer if given prior to arrival)

→ Pulse oximetry, if SPO2 less than 95%

►Oxygen by mask or nasal cannula

→ ALS Escort

Allergic Reaction Includes:  

(wheezing or hypoxia - SPO2 < 95%):


► High flow oxygen by mask as tolerated.

Epinephrine 0.01 mg/kg IM Lateral Thigh area (1 mg/mL), may repeat once (approx. 5 min) (Max dose of 0.5 mg)

(If Epi pen given PTA, consider that the first dose)

►Oxygen by mask or nasal cannula

Albuterol 5mg (6 mL) nebulize continuous as tolerated

Diphenhydramine 1 mg/kg IV/IM/IO, (Max of 40 mg or 0.8 mL of 50 mg solution)
(Do not administer if given prior to arrival)

→ ALS Escort

 

 

Allergic Reaction Includes:  

(hypotension, respiratory distress, impending airway obstruction) (BHC)


► High flow oxygen by mask as tolerated

Epinephrine IV preferred if established, if not use Epinephrine IM
Epinephrine 0.01 mg/kg IM Lateral Thigh area (1 mg/mL), may repeat once (approx. 5 min) (Max dose of 0.5 mg)

or

Epinephrine: 0.01 mg/kg slow IV/ IO (0.1 mg/mL) (Max single dose of 0.3 mg)

If signs or symptoms of poor perfusion:

► Establish IV/IO access

Normal Saline: Infuse 20 mL/kg NS bolus IV / IO (Max 250 mL) may repeat twice to maintain perfusion
 

→ If after 5 minutes there is continued signs of respiratory distress, or impending airway obstruction

Epinephrine: 0.01 mg/kg slow IV/ IO (0.1 mg/mL) (Max single dose of 0.3 mg)

or

Epinephrine: 0.01 mg/kg IM Lateral Thigh area (0.1 mg/mL) (Max single dose of 0.5 mg)

→ If wheezing present:
Albuterol: 5 mg (6 mL) nebulize continuous as tolerated

Diphenhydramine 1 mg/kg IV/IM/IO, (Max of 40 mg or 0.8 mL of 50 mg solution)

(Do not administer if given prior to arrival)

 

→ Contact a Pediatric Resource Center/Base Hospital and ALS escort as directed to CCERC or ERC
