[MENTION=364367]stoney[/MENTION], I have a question for you.

Mrs BD has a clear adhesive plastic film over her knee incision site(s) that allows her to take a shower and 100% prevents the wound from getting wet. Instructed to leave it alone for two weeks until the wounds heal.

This is a new revelation to me because I was from the apparently outdated school of thought that a wound needed air to heal properly. This plastic film obviously prevents that, and the nurse said these wounds heal from within. Is this a recent discovery or is it new technique?

I mean, I 100% trust in what they're telling me, it just conflicts with my prior knowledge.
