Randomized Controlled Trial
Reliability and validity of a visual analogue scale used by owners to measure chronic pain attributable to osteoarthritis in their dogs.
To assess validity and reliability for a visual analogue scale (VAS) used by owners to measure chronic pain in their osteoarthritic dogs. ⋯ Although valid and reliable, the pain VAS was a poor tool for untrained owners because of poor face validity (ie, owners could not recognize their dogs' behavior as signs of pain). Only after owners had seen pain diminish and then return (after starting and discontinuing NSAID use) did the VAS have face validity.

Randomized Controlled Trial
Refinement and initial validation of a multidimensional composite scale for use in assessing acute postoperative pain in cats.
To refine and test construct validity and reliability of a composite pain scale for use in assessing acute postoperative pain in cats undergoing ovariohysterectomy. ⋯ Results provided initial evidence of construct validity and reliability of a multidimensional composite tool for use in assessing acute postoperative pain in cats undergoing ovariohysterectomy.

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.

Randomized Controlled Trial
Comparison of recovery from anesthesia with isoflurane, sevoflurane, or desflurane in healthy dogs.
To determine the quality and speed of recovery from anesthesia with isoflurane, sevoflurane, or desflurane and determine end-tidal inhalant concentration at certain events during recovery in healthy dogs. ⋯ Results suggested that in dogs for which a short interval to standing is desired, desflurane is the best selection, followed by sevoflurane.

Randomized Controlled Trial
Effect of remifentanil on requirements for propofol administered by use of a target-controlled infusion system for maintaining anesthesia in dogs.
To evaluate the effect of remifentanil administered by use of a constant rate infusion on the predicted plasma concentration (Cp(predicted)) of propofol required to prevent awareness in 50% of anesthetized dogs (Cp50(predicted)). ⋯ In nonpremedicated dogs, propofol Cp50(predicted) of 6.0 microg/mL may be recommended for induction of anesthesia. Propofol requirements for maintaining target-controlled infusion system-based anesthesia were reduced via infusion of remifentanil at a rate of 0.3 microg/kg/min.
