Veterinary anaesthesia and analgesia
-
Randomized Controlled Trial
Cardiopulmonary effects of dexmedetomidine and ketamine infusions with either propofol infusion or isoflurane for anesthesia in horses.
To examine the cardiopulmonary effects of two anesthetic protocols for dorsally recumbent horses undergoing carpal arthroscopy. ⋯ Both anesthetic protocols were suitable for arthroscopy. Administration of oxygen and ability to ventilate lungs is necessary for propofol-based anesthesia.

Randomized Controlled Trial
Influence of ketamine or xylazine supplementation on isoflurane anaesthetized horses--a controlled clinical trial.
To determine the influence of ketamine or xylazine constant rate infusions on isoflurane requirements, cardiovascular parameters and quality of anaesthesia in horses undergoing elective surgery. ⋯ All three protocols provided good clinical anaesthesia with clinically acceptable cardiovascular effects.
-
Randomized Controlled Trial
Chronotropic effect of propofol or alfaxalone following fentanyl administration in healthy dogs.
To compare the effect of alfaxalone and propofol on heart rate (HR) and blood pressure (BP) after fentanyl administration in healthy dogs. ⋯ Following fentanyl administration, HR decreases more frequently when propofol rather than alfaxalone is used as induction agent. However, given the high individual variability and the small change in predicted HR (-7.7 beats per minute after propofol), the clinical impact arising from choosing propofol or alfaxalone is likely to be small in healthy animals. Further studies in dogs with myocardial disease and altered haemodynamics are warranted.

Randomized Controlled Trial
Evaluation of intravenous administration of alfaxalone, propofol, and ketamine-diazepam for anesthesia in alpacas.
To evaluate the effects of induction of anesthesia with alfaxalone in alpacas. ⋯ All protocols were adequate for induction of anesthesia. Alfaxalone alone in unpremedicated alpacas is not recommended.
-
Randomized Controlled Trial
Cardiorespiratory, sedative and antinociceptive effects of dexmedetomidine alone or in combination with methadone, morphine or tramadol in dogs.
To evaluate the cardiorespiratory, sedative and antinociceptive effects of dexmedetomidine alone or in combination with methadone, morphine or tramadol in dogs. ⋯ The treatments with morphine and methadone added to the dexmedetomidine showed higher sedation scores than the control treatment and the treatment with tramadol added to the dexmedetomidine showed no relevant differences in any of the variables evaluated in the study.
