Using auto-injectors for anaphylaxis

Adrenaline Auto-injectors

There are a variety of auto-injectors available. Make sure you are familiar with the ones you will be using for your vaccination sessions. They are designed to go through clothing for speed of delivery.

 Epipen (Available in Adult dose – 300mcg, paediatric dose 150mcg)

    • Keep your thumb out of the way, hold the Epipen like a dagger.
  • Pull off the blue safety cap

 

    • Hold the device about 10cm from the outer thigh with the orange tip pointing to the thigh
    • Swing and push the device against the thigh until it clicks.
    • Hold in place for 10 seconds to ensure the whole dose is administered.
    • Massage the area afterwards to encourage blood supply

 Jext (Available in Adult dose – 300mcg, paediatric dose – 150mcg)

    • Hold the Jext like a dagger in your dominant hand
    • Remove yellow cap
    • Place black tip against outer thigh, then push injector firmly into thigh until it clicks
    • Hold in place for 10 seconds
    • Massage the area afterwards to encourage blood supply 

Emerade (Available in all three doses – 500mcg, 300mcg, 150mcg)

    • Advantages
      • higher adult dose in line with guidelines
      • longer needle (reduces risk of being administered subcutaneously)
      • more intuitive design
    • Remove needle sheath
    • Press device against outer thigh
    • Hold in place for 5 seconds
    • Massage the area afterwards to encourage blood supply

Adrenaline ampoules – if you are needing to use these instead of auto-injectors (if you have been trained to do so)

Alternatively, you may be using adrenaline ampoules to draw up the required dose. Standard needles are not designed to go through clothing so the thigh would need to be exposed for adrenaline to be given.

Use an appropriate size needle to draw up the required dose from the ampoule and administer the adrenaline.

    • A blue needle (25mm) is suitable for all ages
    • A green 38mm needle should be used for very large adults

 

Points to note

    • If a second dose is required use a new ampoule
    • If ampoule is not opened with a clean break (potential for broken glass) then dispose of ampoule and start again
    • Keep the tip of needle in solution & tip ampoule to make drawing up the liquid easier
    • Air needs to be expelled from the syringe when drawing up from ampoule
