Efficacy of ketamine hydrochloride administered as a basilar sesamoid nerve block in alleviating foot pain in horses caused by natural disease

Abstract

Ketamine (3%) administered perineurally for regional anaesthesia of the digit does not desensitise the digit to the same extent as does lidocaine and thus 3% ketamine appears to have no value as a local anaesthetic agent for diagnostic regional anaesthesia.

Duration and Efficacy of Different Local Anesthetics on the Palmar Digital Nerve Block in Horses

“…Bidwell et al [5] conducted a study evaluating the duration of mepivacaine in horses with navicular syndrome using a force plate; they observed complete analgesic effect between 15 and 60 minutes after blockade. Schumacher et al [6] observed inefficacy of ketamine as a local anesthetic agent when compared with lidocaine in abaxial nerve block in horses with chronic lameness evaluated with the aid of a body-mounted inertial sensor system. Differently from the studies mentioned previously, several authors have evaluated the efficacy and duration of local anesthetics using the heat-lamp model to observe the loss of cutaneous sensitivity [7][8][9][10].…”

Response to Letter to the Editor: Do we have to redefine lameness in the era of quantitative gait analysis

“…Inertial sensor measurements have been shown, through testing with induced lameness models, to be strongly related to lameness [3][4][5][6][7][8][9][10][11][12][13]. Suggesting this exposes a misunderstanding of how this measurement method works.…”

“…We should admit they are only an expert opinion. Inertial sensor measurements have been shown, through testing with induced lameness models, to be strongly related to lameness [3][4][5][6][7][8][9][10][11][12][13]. Drs Bathe, Judy and Dyson state they have experienced cases where reliance on inertial measurement systems, even in skilled hands, has led to conclusions that did not fit with the findings on a thorough conventional work-up.…”
