I am posting this for medical info for future, in case anyone is interested.
This sounds like sepsis (blood poisoning), also called septicemia. This is when the infection gets into the bloodstream. For future reference septicemia or severe infection should be treated with iv fluids and iv antibiotics - in hospital - by good qualified rabbit vet.
Ahead of time, properly dosed durapen (or possibly Amikacin AND Baytril injections), plus properly anesthetized and cleaned wound area. Pain control - *injectable * Metacam. Durapen is usually dosed every other day, but can be given daily. In US no dilution is necessary, but dilution IS necessary with the Amikacin and Baytril. And using a wash cloth soaked in hot water and Epsom Salts several times a day - which can help draw out infection.
I prefer Amikacin and Baytril because they cover a broad range bacteria and rarely get a negative reaction from bunnies.
I just wanted to leave this info for anyone. In case.
