Veterinary anaesthesia and analgesia
-
Randomized Controlled Trial
A comparison of subarachnoid buprenorphine or xylazine as an adjunct to lidocaine for analgesia in goats.
To test the hypothesis that subarachnoid administration of buprenorphine and lidocaine provides more intense and longer lasting perioperative analgesia with less side effects than xylazine and lidocaine in goats. ⋯ In these goats undergoing hind limb surgery, subarachnoid buprenorphine/lidocaine offered more intense and longer lasting analgesia than a xylazine/lidocaine combination, with less sedation and impairment of cardiopulmonary function.

Randomized Controlled Trial
Effect of lidocaine on the minimum alveolar concentration of sevoflurane in dogs.
To investigate the effects of a low-dose constant rate infusion (LCRI; 50 microg kg(-1) minute(-1)) and high-dose CRI (HCRI; 200 microg kg(-1) minute(-1)) lidocaine on arterial blood pressure and on the minimum alveolar concentration (MAC) of sevoflurane (Sevo), in dogs. ⋯ Lidocaine infusions dose dependently decreased the MAC of Sevo, did not induce clinically significant changes in HR or arterial blood pressure, but vomiting was common during recovery in HCRI.

Randomized Controlled Trial
A study of cardiovascular function under controlled and spontaneous ventilation in isoflurane-medetomidine anaesthetized horses.
To determine, in mildly hypercapnic horses under isoflurane-medetomidine balanced anaesthesia, whether there is a difference in cardiovascular function between spontaneous ventilation (SV) and intermittent positive pressure ventilation (IPPV). ⋯ In horses with health status ASA I and II, cardiovascular function under general anaesthesia is equal with or without IPPV if the PaCO(2) is maintained at 50-60 mmHg.

Randomized Controlled Trial
Effects of graded doses of propofol for anesthesia induction on cardiovascular parameters and intraocular pressures in normal dogs.
To determine the effects of graded doses of propofol on cardiovascular parameters and intraocular pressures (IOP) in normal dogs. ⋯ Graded doses of propofol did not affect the increase in IOP observed with propofol induction in normal dogs. Higher doses of propofol are of no apparent additional benefit in animals who cannot tolerate an abrupt increase in IOP but may be of benefit in dogs who cannot tolerate an abrupt increase in blood pressure accompanying orotracheal intubation.

Randomized Controlled Trial
Analgesic and motor-blocking action of epidurally administered levobupivacaine or bupivacaine in the conscious dog.
To compare the analgesic and motor-blocking effects of epidurally administered levobupivacaine and bupivacaine in the conscious dog. ⋯ Epidural levobupivacaine is suitable for clinical use in dogs, mostly at the highest dose if a high degree of analgesia is required.
