Fentanyl citrate is a potent opioid that can be delivered by the transdermal route in cats and dogs. Publications regarding transdermal fentanyl patches were obtained and systematically reviewed. Seven studies in cats and seven studies in dogs met the criteria for inclusion in this review. ⋯ Cats achieved effective plasma concentrations 7 hours after patch application. In dogs, transdermal fentanyl produced analgesia for up to 72 hours, except for the immediate 0- to 6-hour postoperative period. In cats, transdermal fentanyl produced analgesia equivalent to intermittent butorphanol administration for up to 72 hours following patch application.

Randomized Controlled Trial Clinical Trial
The effects of cryoanalgesia combined with thoracic epidural analgesia in patients undergoing thoracotomy.
This study was performed to evaluate the effects of cryoanalgesia combined with thoracic epidural analgesia on pain and respiratory complications in patients undergoing thoracotomy. Ninety patients were prospectively randomised to epidural analgesia alone (n = 45) or epidural analgesia and cryoanalgesia combined (n = 45). We monitored the use of rescue pain medication and changes in forced vital capacity and forced expired volume in 1 s, and recorded pain and opioid-related side-effects during the immediate postoperative period. ⋯ Cryoanalgesia combined with thoracic epidural analgesia was associated with earlier recovery in pulmonary function, less pain during movement and a lower daily requirement for rescue analgesia one week after surgery. However, the combination of cryoanalgesia and epidural analgesia failed to decrease the incidence of long-term pain and numbness. In view of its associated long-term morbidity, cryoanalgesia combined with thoracic epidural analgesia is not recommended for patients undergoing thoracotomy.

Randomized Controlled Trial Comparative Study Clinical TrialContinuous subacromial bupivacaine infusion for postoperative analgesia after open acromioplasty and rotator cuff repair: preliminary results.
Shoulder surgery is often associated with severe postoperative pain. Previous results in which single or continuous subacromial infiltration of local anesthetics was used as a method of postoperative pain relief have been contradictory. This study was initiated to evaluate the postoperative analgesic effect of a subacromial continuous 0.25% bupivacaine infusion at a rate of 6 mL/h after elective open shoulder surgery. ⋯ No major technical or pharmacologic side effects were noticed, and the indwelling pain catheter was well tolerated by all patients. There was no statistically significant difference (P < .05) either in total cumulative morphine consumption microg/48 h (73.2 +/- 43.1 vs 60.9 +/- 35.9) or in subjective pain perception 10-point visual analog scale (3.2 +/- 1.4 vs 3.1 +/- 1.5) between the two study groups. The continuous subacromial infiltration of 0.25% bupivacaine at a rate of 6 mL/h is concluded to be ineffective in providing pain relief supplementary to patient-controlled analgesia after open rotator cuff repair and acromioplasty surgery.

Randomized Controlled Trial Comparative Study Clinical Trial
When to inject analgesic agents intra-articularly in anterior cruciate ligament reconstruction: before or after tourniquet releasing.
To evaluate 2 different applications of an intra-articular (IA) mixture composed of 40 mL 0.25% bupivacaine and 2 mg morphine in anterior cruciate ligament (ACL) reconstructions, before and after tourniquet release. ⋯ Level I.
