Therapeutic Use of Regional Limb Perfusion in a Chicken.

A 2-year-old, 3.8-kg male Rhode Island red rooster was examined for lameness and progressive swelling of the right foot of several month's duration. Radiographs of the right foot demonstrated soft tissue swelling and a smoothly marginated periosteal reaction evident of inflammation affecting the bones. Results of a complete blood count showed a moderate leukocytosis and an elevated total protein concentration. Systemic antibiotic and anti-inflammatory therapy was started, but the bird had not improved at recheck examination. After intravenous catheterization of the medial metatarsal vein and placing a tourniquet at the femoral-tibiotarsal joint of the right leg, regional limb perfusion with amikacin and flunixin meglumine was performed. Dimensions of both feet were measured with digital calipers, and surface temperatures of the feet were measured with an infrared thermometer. The rooster had improved activity level with decrease in lameness and measurable decrease in swelling of the right foot. Regional limb perfusion with intravenous antibiotics and nonsteroidal anti-inflammatory drugs is a viable treatment modality in avian species for suspected distal limb infection and cellulitis. This technique has potential valuable implications for a variety of avian species. Fluid support should be provided if using nephrotoxic drugs.
