The usual treatment for pain after limb amputation of a dog is to use a variety of drugs, including narcotics. These drugs have side effects such as respiratory depression, nausea, vomiting and sedation. Dr. Bonnie Hay Kraus, board-certified anesthesiologist at the VMC, has received a grant to evaluate the effectiveness of using a wound infusion catheter to deliver local anesthetic drugs to the surgical site after limb amputation. It is hoped that this method of pain alleviation will be more effective and less side effects than current pain control methods. Veterinarians who are referring patients to the ISU Oncology or Soft Tissue Surgical service that may be candidates for this clinical trial may contact Dr. Hay Kraus at (515) 294-4900.
