It may be worth discussing using F10 to flush the wound. It is a very effective antibacterial but without the irritant effects of hibiscrub. We use it for wound cleaning without any adverse effects and it kills pretty much all bugs
Can you post the whole sensitivity. This is one I would consider the use of Antibiotic impregnated methylmethacrylate beads as well as as much debridement as possible. Have you had radiographs, this will let you know about bony involvement and affect prognosis and aggression of debridement
Goodluck
If you could get one that would help. If the bone is affected you will need a long course of systemic treatment as well as topical. If what you say is correct and you are getting necrotic tissue out, I would consider the possiblity of a nidus of infection that would require debridement. these are very frustrating cases and I frequently end up being quite radical about debriding, closing the dead space and removing anything that looks in any way necrotic. Is ther communication with the oral cavity?
It may be that if they still have the culture, further sensitivities could be carried out. Also I wouldnt rule out the fact that in vitro sensitivity doesnt always apply in vivo so penicillin injections might not yet be ruled out
Hope this helps
If tetracyclines have been indicated on the sensitivity, another little trick is to get some itrasite gel from your vet and also some ornicure sachets. Ornicure is doxycycline. I mix some with the intrasite gel and this makes a doxycycline paste to apply to the abscess. Intrasite encourages healing and granulation. I sometimes pack abscesses with this mixture and it works well. I have a whole array of treatments i use for specific abscesses and the doxycycline intrasite mixture is one i have had significant success with.
Goodluck
Mack has a check-up at 6pm tonight with Rob when I will be discussing some of the suggestions on this thread with him. Can we have some positive vibes that things are progressing well please... his weight seems to have dropped again so I'm hoping this is just a temporary blip.
Jill, I'll reply to your PM this evening when I have some news.
