Keep the Tort calm (as well as yourself) Keep the wound CLEAN CLEAN CLEAN! If you have the ability to get sterile saline (saline a drugstore would be ok, IE cotact lens saline-make sure SALINE ONLY) so you can flush over the wound every few hours. Ligate the wound carefully, and make sure when you re-apply the bandage you use a CLEAN one each time. You want to keep any infection from getting in (Tho more than a few hours old and it starts to happen no matter how clean you keep it) Make sure just to use regular cotton gauze, do not cover it with something that is not breathable (it will make bacteria grow bad) You can place the tort in a clean cardboard or rubbermaid box (no food, no dirt) with a small dish of water. You may place a heatpad set on LOWEST setting underneath, but make sure the turtle can get away from the pad if neccisary. The heat helps with any shock the turtle might be in.
What you are trying to fight right now is infection from taking hold. The vet will trim any necrotic tissue out of the area and sterilize the area thouroghly before applying a seal on the shell. Most of thesetraumatic injuries heal very well, but its very important to get the tort to the vet ASAP to prevent much tissue die off or infection from setting in. Most likley the tort will go on antibiotics anyway---just so you are prepared. If you have the ability please post a pic so I can see how bad it is, and I might have more suggestions once i see how extensive it is.
If you do have the ability to get to an emergency vet hospital I would highley reccomend it. If an infecction is to set in (and it normally does within hours) Its alot harder for it to heal and some infection can kill the tort especially if its sealed up. Its also much harder to patch a wound once it has become traumatized and swollen. This is very life threatening stuff. If the injury involves the spine (attached inside ths shell) the progosis can be poor, bit you need to see a vet .
Good luck to you,
If you have anymore questions feel free to ask.
