Cold limb syndrome appears as areas of complete or patchy photopenia in the carpus/tarsus and distal limb which can efface areas of IRU. It can occur in any patient, but the incidence increases in cold weather and when the horse cannot be exercised. The majority of suspected fracture patients will be unsafe to exercise in a manner that will enhance distal limb perfusion. In order to try and minimize the incidence of cold limb syndrome and to optimize perfusion, and thus radiopharmaceutical distribution, patients can be stable bandaged and rugged overnight and, prior to injection of the radiopharmaceutical, placed in a stable with radiating heat lamps and a deep shavings bed (for at least one hour) and administered acetylpromazine. Maintaining the patient in a stable with heat lamps for the period between injection and image acquisition has proved the most reliable method for minimizing/eliminating cold limb syndrome.
