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
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.

This study was conducted to evaluate the performance of a new veterinary oscillometric noninvasive blood pressure (NIBP) monitor in anesthetized dogs. ⋯ Noninvasive blood pressure measurements with a new oscillometric monitor provided an excellent means of detecting arterial hypotension in anesthetized dogs. The metatarsal site for cuff placement was slightly better than the metacarpal or anterior tibial site, considering that the regression line was closest to complete equality between the indirect and direct measurements for SAP.

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.

Randomized Controlled Trial Clinical Trial
Plasma fentanyl concentrations in awake cats and cats undergoing anesthesia and ovariohysterectomy using transdermal administration.
To measure the plasma fentanyl concentrations achieved over time with transdermal fentanyl patches in awake cats and cats undergoing anesthesia and ovariohysterectomy. ⋯ The high degree of variability observed suggests that careful observation of cats with fentanyl patches in place is required to assess efficacy and any potential adverse effects. Anesthesia and anesthesia/ovariohysterectomy do not appear to alter plasma fentanyl concentrations achieved by placement of a 25 micro g hour-1 transdermal fentanyl patch when compared to cats not undergoing these procedures.
