ANAPHYLAXIS MANAGEMENT
![Page 2: A NAPHYLAXIS M ANAGEMENT. 3 R S FOR T REATING A NAPHYLAXIS.](https://reader035.fdocuments.in/reader035/viewer/2022062517/56649f1e5503460f94c368a1/html5/thumbnails/2.jpg)
3 RS FOR TREATING ANAPHYLAXIS
![Page 3: A NAPHYLAXIS M ANAGEMENT. 3 R S FOR T REATING A NAPHYLAXIS.](https://reader035.fdocuments.in/reader035/viewer/2022062517/56649f1e5503460f94c368a1/html5/thumbnails/3.jpg)
DON’T LOSE PRECIOUS TIME!!!
Early recognition of an anaphylactic reaction is mandatory, since death occurs within minutes to
hours after the first symptoms.

AT THE EMERGENCY ROOM

POSITION
![Page 8: A NAPHYLAXIS M ANAGEMENT. 3 R S FOR T REATING A NAPHYLAXIS.](https://reader035.fdocuments.in/reader035/viewer/2022062517/56649f1e5503460f94c368a1/html5/thumbnails/8.jpg)
AIRWAY, BREATHING, CIRCULATION Assess airway patency because of the probability of
edema or bronchospasm
If there is severe laryngeal edema, intubation may be difficult to do. Instead, ventilate the patient with a bag-valve-mask
(cricothyrotomy is reserved when both intubation and bag-valve-mask ventilation are not possible)
High flow oxygen. O2 saturation must be maintained at above 90%
![Page 9: A NAPHYLAXIS M ANAGEMENT. 3 R S FOR T REATING A NAPHYLAXIS.](https://reader035.fdocuments.in/reader035/viewer/2022062517/56649f1e5503460f94c368a1/html5/thumbnails/9.jpg)
ESTABLISH IV ACCESS For fluid therapy
isotonic crystalloid solutions (such as NSS or LRS) to address the hypotension
Since there is hypotension and tachycardia, a fluid bolus of 1L can be given. Further fluid therapy depends on patient response
![Page 10: A NAPHYLAXIS M ANAGEMENT. 3 R S FOR T REATING A NAPHYLAXIS.](https://reader035.fdocuments.in/reader035/viewer/2022062517/56649f1e5503460f94c368a1/html5/thumbnails/10.jpg)
MONITORING Cardiac monitoring: ECG
Blood Pressure monitoring
Pulse Oximetry: to monitor respiratory output and gas exchange
![Page 11: A NAPHYLAXIS M ANAGEMENT. 3 R S FOR T REATING A NAPHYLAXIS.](https://reader035.fdocuments.in/reader035/viewer/2022062517/56649f1e5503460f94c368a1/html5/thumbnails/11.jpg)
MEDICATIONS
![Page 12: A NAPHYLAXIS M ANAGEMENT. 3 R S FOR T REATING A NAPHYLAXIS.](https://reader035.fdocuments.in/reader035/viewer/2022062517/56649f1e5503460f94c368a1/html5/thumbnails/12.jpg)
EPINEPHRINE Drug of choice for life threatening reactions
Given in patients with systemic manifestations of anaphylaxis
Can counteract the bronchospasm, hypotension, and GI symptoms
![Page 13: A NAPHYLAXIS M ANAGEMENT. 3 R S FOR T REATING A NAPHYLAXIS.](https://reader035.fdocuments.in/reader035/viewer/2022062517/56649f1e5503460f94c368a1/html5/thumbnails/13.jpg)
EPINEPHRINE Increases systemic vascular resistance
elevating diastolic pressure
Bronchodilation
increasing inotropy
Increasing chronotropy of the heart
reduces edema
![Page 14: A NAPHYLAXIS M ANAGEMENT. 3 R S FOR T REATING A NAPHYLAXIS.](https://reader035.fdocuments.in/reader035/viewer/2022062517/56649f1e5503460f94c368a1/html5/thumbnails/14.jpg)
Alpha Receptor Reverses vasodilation by vasoconstriction Reduces edema
Beta Receptor Dilates broncial airways On the heart: inc inotrophy and chronotropy Suppress histamine and leukotriene release Inhibit activation of mast cells
EPINEPHRINE

DOSAGE Given IV (if not possible, IM on anterolateral thigh)
![Page 16: A NAPHYLAXIS M ANAGEMENT. 3 R S FOR T REATING A NAPHYLAXIS.](https://reader035.fdocuments.in/reader035/viewer/2022062517/56649f1e5503460f94c368a1/html5/thumbnails/16.jpg)

MANAGEMENT: FOLLOW UP
![Page 20: A NAPHYLAXIS M ANAGEMENT. 3 R S FOR T REATING A NAPHYLAXIS.](https://reader035.fdocuments.in/reader035/viewer/2022062517/56649f1e5503460f94c368a1/html5/thumbnails/20.jpg)
ALLERGEN AVOIDANCE Avoid exposure to
inciting agent (such as peanuts).
If peanuts were not included in the breakfast or the inciting agent cannot be identified, referral to an allergologist.
