Veterinary anaesthesia and analgesia
-
Randomized Controlled Trial
Differences in need for hemodynamic support in horses anesthetized with sevoflurane as compared to isoflurane.
To study whether hemodynamic function in horses, particularly mean arterial blood pressure (MAP), is better maintained with sevoflurane than isoflurane, thus requiring less pharmacological support. ⋯ Horses under sevoflurane anesthesia may require less pharmacological support in the form of dobutamine than isoflurane-anesthetized horses. This could be due to less suppression of vasomotor tone.

Randomized Controlled Trial
A comparison of four methods of analgesia in cats following ovariohysterectomy.
To evaluate the effectiveness of preoperative administration of oral carprofen, subcutaneous ketoprofen, and local nerve block with bupivacaine in preventing postoperative pain-associated behavior in cats after ovariohysterectomy. ⋯ Preoperative carprofen and ketoprofen have effects on pain-associated behavior similar to butorphanol in cats undergoing ovariohysterectomy. Cats receiving bupivacaine blocks may require additional analgesics immediately after surgery.

To determine the minimum alveolar concentration (MAC) of desflurane in llamas and alpacas. ⋯ The MAC of desflurane in llamas and alpacas was in the range of that reported for other species.

Randomized Controlled Trial
The effect of nitrous oxide on halothane, isoflurane and sevoflurane requirements in ventilated dogs undergoing ovariohysterectomy.
To examine the effect of 64% nitrous oxide (N2O) on halothane (HAL), isoflurane (ISO) or sevoflurane (SEV) requirements in dogs undergoing ovariohysterectomy. ⋯ N2O reduces HAL, ISO and SEV requirements in dogs undergoing ovariohysterectomy. Cardiovascular stimulation occurred when N2O was used with ISO, less so with SEV and not with HAL

Randomized Controlled Trial
Investigation of the interaction between buprenorphine and sufentanil during anaesthesia for ovariectomy in dogs.
To investigate the effect of buprenorphine pre-treatment on sufentanil requirements in female dogs undergoing ovariectomy. ⋯ Withholding buprenorphine therapy 6-8 hours before anaesthesia incorporating pure mu receptor agonists is probably advisable. Alternative methods of analgesia should be provided in this period.
