To compare cardiac output measured by oesophageal Doppler and by thermodilution monitoring and to correlate the Doppler cardiac output-generated minute distance with thermodilution cardiac output in healthy anaesthetised beagle dogs. ⋯ Doppler and minute distance cannot be considered as an alternative method to thermodilution to monitor cardiac output in the healthy anaesthetised dog.

Fentanyl is used in small animals for perioperative analgesia during anaesthesia. Severe bradycardia and asystole were observed on bolus administration of a 3 µg/kg loading dose of fentanyl in two dogs under isoflurane anaesthesia. ⋯ This case report describes asystole induced by fentanyl administration in isoflurane anaesthetised dogs. Atropine was more effective than glycopyrrolate in the treatment of fentanyl-induced asystole.

Anecdotal reports suggest a recent high prevalence of aspiration pneumonia in Irish wolfhounds, prompting further investigation into the incidence of the disease in this breed. ⋯ On the basis of the hospital population studied, the Irish wolfhound has a high incidence of aspiration pneumonia. Further investigation into the possible predisposing cause(s) in this breed is warranted.

To determine whole blood and serum concentrations of l-lactate and serum concentrations of d-lactate in healthy rabbits and compare three methods of analysis for l-lactate measurement. ⋯ Serum concentrations of d-lactate in healthy rabbits are in the range of those of other mammals. l-lactate values in healthy rabbits are higher compared with other mammals. Good correlation was found between the portable and blood gas analysers for whole blood l-lactate measurement in healthy rabbits.

To document efficacy of intra-articular mepivacaine in dogs based on the hypothesis that this would blunt the haemodynamic response to a nociceptive stimulus (arthroscopic surgery), reducing interventional analgesia requirements. ⋯ Intra-articular mepivacaine blunts the haemodynamic response to arthroscopic surgery in dogs and reduces interventional analgesia requirement.
