Randomized Controlled Trial Comparative Study Clinical Trial
Effects of oxypolygelatin and dextran 70 on hemostatic variables in dogs.
To evaluate and compare coagulation variables following the administration of oxypolygelatin and dextran 70 to clinically healthy dogs. ⋯ Oxypolygelatin causes fewer hemostatic abnormalities when compared to dextran, making it a superior colloid for administration at the doses tested.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of preoperative tramadol and morphine for the control of early postoperative pain in canine ovariohysterectomy.
To compare morphine with tramadol for the management of early postoperative pain following ovariohysterectomy after pyometra in dogs. ⋯ Morphine and tramadol, administered preemptively can be used safely in dogs to control early pain after ovariohysterectomy without significant adverse effects.

To provide evidence concerning doses of ketamine that affect electroencephalographic (EEG) and autonomic signs of arousal during nociceptive stimulation. ⋯ These results show that testing of withdrawal reflexes does not reveal the adequacy of ketamine anesthesia. Segmental stretch and withdrawal reflexes are preserved and can be investigated during infusion of ketamine at doses that eliminate arousal from brief periods of nociceptive stimulation.

Randomized Controlled Trial Clinical Trial
Reduction of isoflurane MAC by fentanyl or remifentanil in rats.
The main objective of the study was to determine the effects of three different infusion rates of fentanyl and remifentanil on the minimum alveolar concentration (MAC) of isoflurane in the rat. A secondary objective was to assess the cardiovascular and respiratory effects of the two opioid drugs. ⋯ The use of remifentanil during inhalant anaesthesia in the rat can be considered an intravenous alternative to fentanyl, providing similar reduction in isoflurane requirements. Due to its rapid offset, it is recommended that alternative pain relief be instituted before it is discontinued.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of the analgesic effects of caudal epidural methadone and lidocaine in the horse.
To evaluate and compare the effects of caudal epidural administration of methadone (METH) and lidocaine (LIDO) on tolerance to thermal stimulation over the dermatomes of the perineal, sacral, lumbar and thoracic regions in the horse. ⋯ Epidural methadone administration provides analgesia with no measured side effects in these healthy adult horses.
