If it does not happen tomorrow, it does not happen until Monday, if you are lucky. For now, I would suggest using some paper tape or something, perpindicular to incision line to reduce tension on the area and diminish chance of dehiscence(busting open). How large is wound, how deep is it and how long ago was surgery? When did stitches/staples come out? What sort of wound care are you doing to the area?

Silver nitrate will give a chemical burn, which is the black that you see when you use the applicator stick. I use it to control bleeding if I am debride(removing non-viable tissue from) a wound. The impact silver can have on wound healing is very interesting. It is anti-bacterial, and can actually stimulate healing. Ag used in a lot of wound care products.
