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.

To review the literature with regard to the use of different intravenous agents as supplements to inhalational anaesthesia in horses. The Part 2 of this review will focus in the use of opioids and α2 -agonists. ⋯ Different drugs and their combinations can be administered systemically in anaesthetized horses aiming to reduce the amount of the volatile agent while improving the recovery qualities and providing a multimodal analgesic approach. However, full studies as to whether these techniques improve cardiopulmonary status are not always available and potential disadvantages should also be considered.

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.

Clinical Trial
Pharmacokinetic-pharmacodynamic modelling of intravenous buprenorphine in conscious horses.
Describe the pharmacokinetics of buprenorphine and norbuprenorphine in horses and to relate the plasma buprenorphine concentration to the pharmacodynamic effects. ⋯ The suitability of the use of buprenorphine for peri-operative analgesia in the horse is supported by the present study.
