ObjectiveTo compare the efficacy of meloxicam administered perioperatively with transdermal administration of fentanyl via a patch placed preoperatively in dogs undergoing orthopedic surgery.DesignProspective study.Animals16 dogs.ProcedureUnilateral or bilateral osteotomy of the tibia and fibula was surgically performed, and a uniplanar external distraction device was placed in each limb. Postoperative pain and lameness were assessed 24, 48, and 72 hours after administration of the first of 3 doses of meloxicam (0.2 mg/kg [0.09 mg/lb], IV, given preoperatively, followed by 0.1 mg/kg [0.045 mg/lb], IV, after 24 hours, and 0.1 mg/kg, PO, after 48 hours) or preoperative placement of a transdermal fentanyl patch (50 microg/h) left in place for 72 hours.ResultsNo significant differences in total pain scores were detected between groups. Mean +/- SD lameness scores assessed at 24 and 72 hours were lower in dogs in the meloxicam group than dogs in the fentanyl group. Lameness scores decreased with time in a similar manner in both treatment groups.Conclusions And Clinical RelevancePerioperative administration of meloxicam or preoperative placement of a transdermal fentanyl patch provided effective and similar postoperative analgesia in dogs undergoing orthopedic surgery. However, because of its anti-inflammatory effects, treatment with meloxicam reduced the degree of lameness and resulted in rapid functional recovery of the limb.
