Q

what is the refractory anaphylaxis algorithm

A

After 2 IM injections of adrenaline with no response:

  • IV fluid bolus
  • continue IMs every 5 mins until infusion up and running

INFUSION

  • 1mg (1mL of 1mg/ml– 1g:1000ml) adrenaline in 100ml 0.9% NaCl
  • start at 0.5-1mL/kg/hour in both adults and children

  • consider glucagon in betablocker pts (reverses)
  • take sample of mast cell tryptase
  • high flow O2, aim spO2 94-98%
  • monitor HR, BP, sats, ECG

NB- hgih BP means adrenaline overdose
