I'm a paramedic...self IVs are possible, but not for a novice. I'd learn from someone before trying. Practice makes perfect. Always be as sterile as possible. Boundtree sells solution tube sets, catheters, & start kits. You should also get very good before using dextrose as it kills tissue...of you are not in the right spot, bad things can happen. Rehydrate with LR because of the added K. Good luck
