“…Thus, they suggested that the administration of 90 mg of guaifenesin/kg followed by 3 mg of propofol/kg would be sufficient to induce anesthesia in > 99% of healthy unsedated horses. 27 Although it is not possible to confirm whether the doses of thiopental, propofol, and ketamine used in the present study are exactly equipotent, these doses are used to achieve the same anesthetic endpoint (centrally mediated immobility) in similar populations (> 99% of healthy adult horses) and are, on the basis of the available literature, 29 clinical experience, and common equine anesthetic practice, approximately equipotent.…”
