route for epi
IM
inclusions pour epi
exposition à un allergene dans les derniers 4h ou adimistration d’épi dans les derniers 7 jours (reaction biphasique)
ET (1 des 2)
1) problemes circulatoire OU détresse respiratoire
2) DEUX des 4
- urticaire (rash) et agioédeme (swelling)
- diff. respiratoire
- défaillance circulatoire
- symptomes gastro-intestinaux
exclusions pour epi
none!
dosage for epi
- 30 mg (≥25kg anaphylaxie… avec pouls)
- 50 mg (≥25 kg cardiac arrest… SANS pouls) after intubation **ONCE ONLY
- 15 mg (< 25kg anaphylaxie… avec pouls)
- 30 mg (< 25kg cardiac arrest… SANS pouls) after intubation ****ONCE ONLY
repetition of epi
q. 5 mins si l’état empire
q. 10mins si aucune améliorations et que les inclusions sont encore présents.
therapeutic effects of epi
will temporarily relieve the person from the allergic reaction…. will open airways and constrict blood vessels
side effects of epi
nausé, vomissemen, maux de tête, tremblements, anxiété et tachycardie
if pt. took an epipen before your arrival, do you still give epi? when?
YES, always give YOUR medication…
right away!
if the allergen is not identified but pt. is known to have anaphylaxia to certain allegens, what do you do?
give epi regardless of the fact that the cause isn’t identified.
how do you manage the O2 on an anaphylactic reaction?
100% O2 mask with 10L
if airways completely closed: UN cycle de dégagement
could an allergy turn into a rea?
yes, REA1 or REA5
If you have a REA with epi….. what is the proper sequence in the protocol?
epi then intubation
pt. would be unconscious because of edema or choc which can be fixed with EPI!! If doesnt work then combitube to protect airways.

Est-ce qu’un pt. qui a reçu de l’épi. et que l’allergie est controlé peut être considéré stable et transporté en 10-16? (Source: QR2018)
non puisqu’il y a trop de risque de récidive et de nécessiter à nouveau de l’épi.
quel est le protocole d’allergie pour les enfants (PED)?
PED5
