@umbra21 - I've read about those clear plastic dressings as well. They actually originated in one of the world wars when the nurses realized the only sterile material available to them was the plastic wrappers of cigarette packaging.
It was actually pretty sophisticated for the time, although I'm sure this kind of hydro gel dressing is much better.
It sounds like it would be much less painful than almost anything else they would traditionally put into that kind of wound. I know with burns they often had a difficult choice between binding them to protect them from infection or leaving them free in the air so that they could heal more effectively.
This new kind of dressing gives them a much better third option, which hopefully will make it more likely for people to survive severe burns. Unfortunately, burns are still one of the most dangerous wounds you can get. If they cover too much of your body, you're very likely to die.
