Randomized Controlled Trial Clinical Trial
Intra-articular lidocaine plus bupivacaine in sheep undergoing stifle arthrotomy.
To evaluate the effect of intra-articular (i.a.) lidocaine plus bupivacaine on post-operative pain in sheep undergoing stifle arthrotomy. ⋯ i.a. lidocaine plus bupivacaine provided analgesia at 3-7 hours post-operatively. Use of i.a. lidocaine and bupivacaine is a simple, effective, yet inexpensive perioperative analgesic protocol for joint surgery in sheep.

Randomized Controlled Trial Clinical Trial
The cardiovascular dose-response effects of isoflurane alone and combined with butorphanol in the green iguana (Iguana iguana).
To assess the cardiovascular effects (arterial blood pressure, heart rate, and metabolic acid-base status) of three doses (MAC multiples) of isoflurane alone and combined with butorphanol in the green iguana (Iguana iguana). ⋯ Cardiovascular depression associated with isoflurane anesthesia in the green iguana is dose dependent. The degree of cardiovascular depression was not significantly different when isoflurane was combined with butorphanol. This finding suggests that the pre-emptive or intraoperative use of butorphanol is unlikely to be detrimental to cardiovascular function. Butorphanol may be a useful anesthetic adjunct to isoflurane anesthesia in the green iguana.

Randomized Controlled Trial Clinical Trial
Evaluation of intraperitoneal and incisional lidocaine or bupivacaine for analgesia following ovariohysterectomy in the dog.
To determine if intraperitoneal (i.p.) and incisional (s.c.) lidocaine or bupivacaine provide analgesia following ovariohysterectomy (OHE). ⋯ Our findings support the use of i.p. and s.c. bupivacaine for post-operative analgesia following OHE in the dog.

Randomized Controlled Trial Clinical Trial
Systemic lidocaine infusion as an analgesic for intraocular surgery in dogs: a pilot study.
To determine if systemic administration of lidocaine during intraocular surgery reduces post-operative ocular pain. ⋯ This pilot study suggests that intraoperative lidocaine may provide analgesic benefits similar to morphine for intraocular surgery in dogs, but more definitive research is needed. This model appears to be appropriate for pain assessment studies as the negative control group demonstrated 100% failure rate.

To investigate the cardiopulmonary effects of a xylazine-guaiphenesin-ketamine infusion combined with inter-coccygeal extradural (lidocaine) anaesthesia in calves. ⋯ Xylazine caused adverse cardiopulmonary effects in calves. Improvement occurred during xylazine-guaiphenesin-ketamine infusion. Cardiac index and arterial blood pressure remained below baseline values while sustained increases in respiration rate and PaCO2 were observed. Inter-coccygeal extradural anaesthesia had only minor effects. Oxygen supplementation proved advantageous during guaiphenesin, ketamine and xylazine infusion in healthy calves in combination with coccygeal extradural anaesthesia induced persistent cardiopulmonary depression.
