Overview of Auto-Injectors

Auto-injectors are vital for self-use by patients at risk of anaphylactic reactions, prescribed individually by allergy specialists.

• Prescription Basis: Auto-injectors should be prescribed based on individual patient needs.
• Cost and Shelf Life: They are relatively expensive with a limited shelf life compared to traditional adrenaline ampoules, syringes, and needles.
• Underutilization: Due to the uncommon nature of anaphylactic reactions, auto-injectors in healthcare settings may not always be used.

Considerations for Healthcare Professionals

Healthcare professionals managing anaphylactic reactions should consider the following:

• Needle Length Concerns: Standard length needles in auto-injectors may not reach intramuscularly in all patients.
• Administration Skills: Most healthcare staff should be proficient in drawing up adrenaline and giving intramuscular injections.
• Course Emphasis: This course assumes proficiency in adrenaline administration; auto-injector use is secondary.
• Local Guidelines: Some healthcare settings may opt for auto-injectors over traditional adrenaline ampoules based on local decisions.

Guideline Differences

Recent discussions by the UK Resuscitation Council highlight differences in dosing intervals:

• Dosing Intervals: Guidelines recommend repeat intramuscular adrenaline every 5 minutes, while some auto-injector manufacturers suggest longer intervals of 10-15 minutes.
• Pragmatic Approach: The 5-minute interval is based on practical experience to ensure timely treatment in severe cases of anaphylaxis.
• Professional Judgment: Healthcare professionals are encouraged to use their training and experience to adapt treatment protocols as needed.
