Vaccinations via intramuscular injection are a key component of preventative health care in horses. Development of problematic behavioral aversion to injections is quite common. Our clinical impression has been that topical anesthetic applied to injection sites can reduce the behavioral reaction;...

Objective: To compare a 2% lidocaine solution containing 5 μg/ml (1:200 000) epinephrine with 2% mepivacaine for reducing lameness in horses after use in proximal nerve blocks. Study design: Experimental randomized crossover. Animals: Six adult horses with naturally occurring forelimb lameness....

There are limited options for treatment of the common disease, equine asthma. The aim of this study was to estimate the feasibility and potential efficacy of using nebulized lidocaine for treating equine asthma, while at the same time treating a separate cohort of asthmatic horses with inhaled...

OBJECTIVE: To compare the extent of inflammation and catabolic collagen response in the middle carpal joints (MCJs) of healthy horses following intra-articular injection of 2% lidocaine, 2% mepivacaine, lactated Ringer solution (LRS), or 1% methyl parahydroxybenzoate. ANIMALS: 17 adult horses....

Objective: To study the surgical, anesthetic and recovery qualities of horses receiving either a neuromuscular blocking agent (atracurium) or intravenous lidocaine (treatment groups A and L, respectively). Animals studied: A total of thirty horses presented for ocular surgery were used in this...

Objective: To compare the corneal anaesthetic effect of 0.5% bupivacaine, 2% lidocaine and 0.4% oxybuprocaine on normal equine eyes . Study design: Prospective, blinded crossover study. Animals: A group of 10 clinically healthy horses. Methods: Corneal sensitivity was determined in each eye by...

The aim of the present study was to establish appropriate doses for both lidocaine hydrochloride (Hcl) and mepivacaine in intravenous regional analgesia (IVRA) and to assess their intraoperative and postoperative analgesic effects in horses with distal limb surgeries. A total of 55 draft horses...

Objective: To evaluate the transdermal local anaesthetic effect of lidocaine or lidocaine combined with prilocaine or tetracaine in horses. Study design: Experimental, randomized study. Animals: A total of five healthy adult warmblood horses. Methods: Horses were clipped bilaterally at the withers, ...

Background: Local anaesthetics are being combined clinically with amikacin in intravenous regional limb perfusion (IVRLP), with limited knowledge on the analgesia provided and its onset and duration of action after tourniquet application and release. Objective To evaluate the systemic clinical...

OBJECTIVE: To determine whether addition of epinephrine to a lidocaine solution would prolong and potentiate the efficacy of a palmar digital nerve block (PDNB) in horses. ANIMALS: 6 adult horses with naturally occurring forefoot lameness. PROCEDURES: Initially, a PDNB with a 2% lidocaine solution...
