Bursotomy Effective for Sepsis of the Navicular Bursa Bursotomy coupled with regional antimicrobial perfusion and remedial farriery is an alternative to bursoscopy with sepsis of the navicular bursa, according to a new study from Iowa State University in Ames. “Contaminated or septic navicular bursitis has been reported to have a guarded prognosis after surgical treatment with navicular bursotomy only. In our experience, the use of navicular bursotomy for the treatment of this disease in combination with systemic and local delivery of antimicrobials can provide a good prognosis, even in horses with chronic disease,” the researchers wrote. The researchers did a case series to evaluate the outcome of 19 horses with septic navicular bursitis that underwent navicular bursotomy. In the majority, the sepsis related to a penetrating foot injury. A standard surgical technique was used to remove part of the deep digital flexor tendon to expose the navicular bursa and perform sterile lavage. The wound was packed and a treatment plate fixed to the affected foot. Systemic antimicrobials were given and IV regional limb perfusion with antimicrobials was performed at surgery and on two to three more occasions postoperatively. The median duration of

clinical signs before surgery was 14 days, with most horses affected for at least seven days. All of the horses survived to discharge from the hospital. Owners were instructed on remedial farriery in the postoperative period. Follow-up owner telephone interviews revealed 16 of 19 horses returned to their previous level of performance, with the median time to return to function being four months. Seven of 10 with an athletic use preoperatively were returned to work at their previous level, with the remaining horses either returning at a lower level or retired. No horses were euthanized or required a repeat surgery, according to the researchers. The alternative approach of bursoscopy offers several advantages over bursotomy, the researchers said, including being less invasive, reduced recovery time and potentially better chances of performing at a high athletic level postoperatively. However, in chronic cases or where there are financial limitations, this case series demonstrated that bursotomy may offer a feasible alternative, especially when concurrent regional limb perfusion and postoperative remedial farriery are employed.

Recent natural disasters emphasize the importance of considering animal safety and welfare. The University of California Davis School of Veterinary Medicine (SVM) and the UC Fire Department recently orchestrated a large animal rescue exercise for Urban Shield 2017, which tests the abilities of regional first responders to prevent, protect, respond and recover in high-threat, high-density urban areas. Jim Green, director and cofounder of the British Animal Rescue and Trauma Care Association (BARTA) and a fire officer in the United Kingdom, helped to integrate the actions of the first responders and veterinarians in emergen-

cies and disasters involving animals. In the U.K., 90% of fire departments have animal rescue components, and veterinarians receive augmented training through BARTA. The exercise scenario involved a trailriding accident with a fallen horse that suffered a repairable fractured leg. The horse owner and riding companions remained at risk from the injured animal (represented by a life-sized mannequin), and the presence of live animals and riders from the Alameda County Sheriff’s Mounted Posse enhanced the reality of the exercise.

sessed the situation and went through the steps involved to anesthetize the horse. The mannequin was then packaged on a glide sheet for recovery from a difficult canyon location using rope systems into an awaiting horse trailer. Dr. Sonder worked closely with the teams to develop an extrication plan, considering the welfare of the horse and the time constraints associated with field anesthesia. MeV | Issue 10/2017
