Why nobody mentioned 3×4 non-stick pads (Telfa)? They are important for scratch types of wounds.
I just use ordinairy gauze. Why? because in my experience, non-sticking pads DO stick to wounds most of the times. If I don't want a wound to stick to the dressing-material, I use Betadine-ointment gauze.
What's the difference between ACE bandage and 3M's Coban wrap and which one is better?
Simple: Coban sticks to itself, ACE doesn't. Coban is also used before doing sport to prevent injuries. ACE is used mostly in First Aid. I haven't really found a difference in performance, but I just use ACE because they are more available to me.
What are ABD pads and what about "kling wrap", what does kling mean?
ABD-pad's stand for ABDominal pads. There basically a gauze pad on steroids. (I use Exupad's, wich are somewhat bigger, but I still call them ABD's)
Kling wrap, is something like Kerlix. 'Kling' is a brand name, just like Kendall, Hartman, NOBA, Klinion, J&J etc.
I hope this answers your questions.
BTW: Nighthiker, I've looked for Kerlix over here. Isn't available. I however do have some PriMed gauze.
