Behavioral response and cost comparison of manual versus pharmacologic restraint protocols in healthy dogs.

Although sedatives are routinely administered to dogs for diagnostic and minimally invasive procedures, manual restraint is often used. The study compared intra-procedural behavioral response, scored on a 100-point, visual analog scale, and cost of restraint in healthy dogs given 1 of 5 treatments: manual restraint, dexmedetomidine at 125 μg/m(2) (Dex 125) or 375 μg/m(2) (Dex 375), Dex 125 plus butorphanol at 0.4 mg/kg (Dex 125 + Bu), or Dex 375 plus butorphanol at 0.4 mg/kg (Dex 375 + Bu). Mean behavioral response scores in dogs declined from baseline in the manual restraint group and improved in a linear fashion in the group order Dex 125, Dex 375, Dex 125 + Bu, and Dex 375 + Bu. Dexmedetomidine at 375 μg/m(2) or at 125 μg/m(2) or at 375 μg/m(2) in combination with butorphanol produced the best intra-procedural behavioral response. The cost of sedative drugs was offset by the opportunity cost of diverting personnel from revenue-generating activity to manual restraint.
