Clot wounds with cornstarch and light pressure(because it's such a tiny lizard, and the location of the wound), paper towel substrate. Not sure how you'll be able to bandage that to keep it clean without making it so that her poop doesn't get on the bandages. I'd try the liquid bandaid type stuff(depending on the fumey nature of it, might be bad idea? Good idea? Use ventilated area so fumes go away? Not certain). Maybe even instead of liquid bandaid, try using a non-toxic glue like elmers? Something to seal it against poop basically.

If you can consult a reptile vet of course, that would be best. Just tossing you some ideas. Best of luck with her.
