A complete blood count and chemical profile performed by Dr. Wiedmeyer show that the horse is stable enough for surgery, but slightly dehydrated. Other tests reveal inflammation, but no rupture in the gastrointestinal tract. After being shaved, the horse is walked to the surgery room. Students lead the horse between two padded gates, and the calculated dose is injected. The horse slowly sinks while the anesthesiologist cradles its head.
Students gradually release pressure on the gates, easing the horse to the floor.
Hobbles are hooked to the horse's legs and a hoist lifts it to the surgery table. A tractor tire and a head rest cushion the horse. Grab the bottles in one hand and scrub with the other. Start in a circle and work your way outward, being careful not to recontaminate what you have already cleaned. Be careful not to contaminate the hand scrubbing the surgery site.
