Evaluating the Effectiveness of a Pain Patch for Dogs Following Surgery

Researchers will evaluate whether a wound dressing containing local anesthetic provides postsurgical pain relief for dogs. The effect of this transdermal lidocaine patch will be evaluated in postoperative dogs by observing behavioral changes and measuring levels of blood cortisol, a hormone that is elevated during times of discomfort. If effective, the lidocaine patch would provide a safe and convenient pain-relief option for dogs, which would be particularly beneficial for use in low-cost veterinary settings such as shelters, teaching hospitals and clinics serving low-income communities.
