To compare the amount of air leakage into the thoracic cavity associated with each of 4 thoracostomy tube placement techniques in canine cadavers. ⋯ Trocar-implemented thoracostomy tube placement in canine cadavers resulted in less air leakage than the forceps method. Air leakage upon tube removal was less pronounced for the LD-CARM technique than the SC-CARM technique. The LD-TRO technique is recommended to prevent iatrogenic pneumothorax in dogs.

Clinical Trial
Effect of administration of propofol and xylazine hydrochloride on recovery of horses after four hours of anesthesia with desflurane.
To compare characteristics of horses recovering from 4 hours of desflurane anesthesia with and without immediate postanesthetic IV administration of propofol and xylazine. Animals-8 healthy horses (mean +/- SEM age, 6.6 +/- 1.0 years; mean body weight, 551 +/- 50 kg). ⋯ Propofol and xylazine administered IV to horses after 4 hours of desflurane anesthesia improved the quality of transition from lateral recumbency to standing but added potential for harmful respiratory depression during the postanesthetic period.

Comparative Study
Effect of firocoxib or flunixin meglumine on recovery of ischemic-injured equine jejunum.
To determine whether treatment of horses with firocoxib affects recovery of ischemic-injured jejunum, while providing effective analgesia. ⋯ Flunixin meglumine retarded mucosal recovery in ischemic-injured jejunum, whereas firocoxib did not. Flunixin meglumine and firocoxib were effective visceral analgesics. Firocoxib may be advantageous in horses recovering from ischemic intestinal injury.

To evaluate pharmacokinetics of ketamine and norketamine enantiomers after constant rate infusion (CRI) of a subanesthetic dose of racemic ketamine or S-ketamine in ponies. ⋯ CRI of S-ketamine may be preferable over CRI of racemic ketamine in standing equids because the S-enantiomer was eliminated faster when infused alone instead of as part of a racemic mixture.

To evaluate the accuracy of a commercial ultrasonographic cardiac output (CO) monitoring system (UCOMS) in anesthetized Beagles as assessed by comparison with thermodilution CO (TDCO). ⋯ When compared with the results of TDCO, CO measured with the UCOMS exceeded commonly accepted limits of error in healthy dogs. The UCOMS was, however, able to track changes in CO across hemodynamic states. Additional research is needed to assess the usefulness of the UCOMS for monitoring CO in critically ill dogs.
