Some type of protective gloves are a good idea. I also have a CPR mask in my kit, along with an 18-inch Sam splint. I keep a small pair of scissors in there, as well.
My first aid kit is intended for Search & Rescue work--though just first responder stuff--so I have some extras, like note-taking supplies (ie. blank SOAP notes)--but most of it is just more of the basics.
Canadian, I'll look into where some of our members get the pre-made Paramedic kits and let you know, if you'd like.
