1. Recognize it was an anaphylaxis shock or not, figure it out soon with pay attention in chriteria :
a. Sudden onset and rapid progression of symptoms
b. Life-Threatening Airway / Breathing / Circulation
c. Skin and/or mucosal changes (flushing, urticaria, angioedema)
- sometiems some people have gastrointestinal sympoms
2. Uses systematical examination as we know in emergency ABCDE:
A (airway) : edema, stridor, hoarseness
B (breathing) : respiration rate raised, wheezing, weakness, cyanosis, anxiety, SPO2 <92 %
C (circulation) : pale, hypotension, drowsy, syncope, coma
if you noticed above, that's sign of life-threatening !
3. Call For Help, Lie patient flat, Raise patient's leg
4. Uses 1st-Line therapy ADRENALIN = 1:1000 Intramuscular anterolateral thigh within 5-10 minutes. (intravenous -- specialist only)
*adult uses : 0.3-0.5 mg
*child uses : 0.01 mg/kg/ maximum 0.3 mg
maybe at the same time you found hypovolemic shock sign (hypotension), you can use crystaloid (normal saline 0.9%) drip fast 1-2L (adult) or 10 mL/Kg (child)
5. Monitoring blood presure, respiration rate, O2 saturation
6. If it doesn't have it's respon, try repeat ADRENALIN injection with interval 5-15 minutes from 1st injection. note : it's just can be given 2 times only.
