Routes to administer adrenalin

Enrolled Nursing student from Tasmania here,

I am just polishing my assignment regarding anaphylaxis and was looking for some clarification or to be advised as to what I may have missed.

The questions says : As adrenaline is the drug of choice for Anaphylaxis, by routes can adrenaline be given and what problems can occur with each of these routes?

Subcutaneous:

• Blood supply is poor
  
• Absorption is slow
  

Intramuscular

• Damage to the nerves especially gluteal
  
• Sterile abcesses can occur
  

Intravenous

• Needle dislodgement
  
• damage to surrounding tissue could lead to Necrosis
  
• Circulatory collapse
  

I'm sure there is more to it than this, any input you may have would be great as you can see I am keeping it simple and as jargon free as possible. Please feel free to e-mail me direct at [email protected]

Thank you in advance.
