Randomized Controlled Trial
A comparison of the duration and quality of recovery from isoflurane, sevoflurane and desflurane anaesthesia in dogs undergoing magnetic resonance imaging.
To compare the recovery after anaesthesia with isoflurane, sevoflurane and desflurane in dogs undergoing magnetic resonance imaging (MRI) of the brain. ⋯ All three agents appeared suitable for use. Dogs' tracheas were extubated and the dogs recovered to sternal recumbency most rapidly after desflurane. This may be advantageous for animals with some neurological diseases and for day case procedures.

Randomized Controlled Trial
Comparison between lithium dilution and pulse contour analysis techniques for cardiac output measurement in isoflurane anaesthetized ponies: influence of different inotropic drugs.
To compare cardiac output () measurements using lithium dilution (LiDCO) and pulse contour analysis (PulseCO) techniques in isoflurane-anaesthetized ponies before and during the administration of different inotropic/vasoactive drugs. ⋯ Pulse contour analysis values deviated significantly from LiDCO measurements in isoflurane-anaesthetized ponies. This difference was influenced by inotropic/vasoactive drugs.

Randomized Controlled Trial
Modulation of nociceptive withdrawal reflexes evoked by single and repeated nociceptive stimuli in conscious dogs by low-dose acepromazine.
To investigate the modulation of the nociceptive withdrawal reflex (NWR) and temporal summation (TS) by low-dose acepromazine (ACP) in conscious dogs. To assess the short- and long-term stability of the reflex thresholds. ⋯ In dogs, 0.01 mg kg(-1) ACP IV had no modulatory action on the NWR evoked by single or repeated stimuli, suggesting no antinociceptive activity on phasic nociceptive stimuli. The evidence of the stability of the NWR thresholds supports the use of the model as an objective tool to investigate nociception in conscious dogs. A low dose of ACP administered as the sole drug, can be used to facilitate the recordings in anxious subjects without altering the validity of this model.

Randomized Controlled Trial
Effects of intraarticular ropivacaine and morphine on lipopolysaccharide-induced synovitis in horses.
To compare the intraarticular (IA) analgesic effects of ropivacaine and morphine in horses with experimentally induced synovitis. ⋯ Morphine alone or in combination with ropivacaine produced a strong analgesic effect of prolonged duration, which may offer pain relief for acute synovitis for at least 24 hours.

Randomized Controlled Trial
The post-tetanic count during vecuronium-induced neuromuscular blockade in halothane-anaesthetized dogs.
To evaluate the post-tetanic count (PTC) for predicting the return of reversible neuromuscular blockade at the n. facialis-m. nasolabialis (nF-mNL) and n. ulnaris-mm. carpi flexorii (nU-mCF) nerve-muscle units (NMUs) during profound vecuronium neuromuscular blockade in halothane-anaesthetized dogs. ⋯ Post-tetanic count monitoring beginning >5 minutes after the TOFC at nU-mCF = 0 provided a reliable estimate of T1's return at ulnar and facial NMUs.
