Randomized Controlled Trial
Evaluation of the analgesic effect of intracameral lidocaine hydrochloride injection on intraoperative and postoperative pain in healthy dogs undergoing phacoemulsification.
To evaluate the intraoperative and postoperative analgesic effects of intracameral lidocaine hydrochloride injection in dogs undergoing phacoemulsification. ⋯ Intracameral lidocaine injection had significant analgesic effects in dogs undergoing cataract surgery. Results of this study suggest the value of intracameral lidocaine injection as an analgesic for intraocular surgery in dogs.

Clinical Trial
Evaluation of electric neurostimulation to confirm correct placement of lumbosacral epidural injections in dogs.
To determine the minimal electric threshold (MET) of neurostimulation in and out of the lumbosacral epidural space necessary to cause muscle contraction of the hind limb or tail, determine an MET cutoff value that indicates epidural needle placement, and compare predictability of epidural needle placement attained by use of neurostimulation versus the standard technique that uses loss of resistance in dogs. ⋯ Neurostimulation is a useful tool to suggest correct lumbosacral epidural needle placement in dogs.

To evaluate the effects of remifentanil on isoflurane minimum alveolar concentration (ISO(MAC)) in dogs. ⋯ Remifentanil decreased ISO(MAC) in a dose-related fashion; the reduction in ISO(MAC) was stable over the course of a prolonged CRI (6 hours). A dose of 0.30 microg of remifentanil/kg/min resulted in nearly maximal isoflurane-sparing effect in dogs; a ceiling effect was observed at higher infusion rates.
