OBJECTIVE: To describe the prevalence of dysphoria after intraoperative administration of fentanyl by infusion and identify other risk factors influencing this in dogs undergoing stifle surgery. STUDY DESIGN: Prospective, randomized clinical study. ANIMALS: Dogs (n = 92) that had tibial plateau leveling osteotomy (TPLO) or tibial tuberosity advancement (TTA). METHODS: Dogs were anesthetized using a standardized anesthetic protocol, and randomly assigned to receive a loading dose followed by 1 of 3 infusions of fentanyl perioperatively: 2 μg/kg/h, 10 μg/kg/h, or 20 μg/kg/h. Dog characteristics and all additional medications were recorded and included as part of the statistical analysis. Dog behavior was scored before anesthesia and during recovery using a scale of 1-4 (Appendices A and B). If no improvement in behavior was seen in 3-5 minutes postextubation, dogs with a score of 3 or 4 during recovery were administered fentanyl (2 μg/kg intravenously [IV]) in the event that the behaviors associated with the higher scores were related to pain. If they did not respond favorably to the administration of additional fentanyl and wound palpation did not elicit a response, but the untoward behaviors continued, dogs were administered either a tranquilizer, sedative, or opioid antagonist, and were considered dysphoric. RESULTS: Of 92 dogs, 22 (23.9%) were considered dysphoric using aforementioned criteria. CONCLUSIONS: About one-fourth of dogs enrolled in this study were dysphoric based on study criteria.

OBJECTIVE: To determine the feasibility, complications, and clinical outcome of consecutive free trapezius flap transfers in 20 dogs and a wallaby. STUDY DESIGN: Case series. ANIMALS: Dogs (n = 20) and 1 wallaby METHODS: Medical records of 20 dogs and 1 wallaby that had free trapezius flap transfers were evaluated retrospectively for indications, date of transfer, site of flap relocation, flap composition (myocutaneous, muscular, myoosseus), recipient artery and veins, flap ischemia times, surgery time, antithrombotic strategies used, intra- and postoperative complications related to the flap, hospitalization, in hospital duration after flap transfer, and outcome. RESULTS: Free flap transfers (16 muscle, 4 myocutaneous, 1 myoosseus) were used to treat traumatic soft tissue loss (13), neoplasm excision (2), osteomyelitis (4), and soft palate reconstruction (2); all flaps survived. Anti-thrombotic therapy was used in all cases although strategies varied. Postoperative complications were infrequent, generally of low severity, and primarily included donor site seroma formation and infection. CONCLUSIONS: Free trapezius flap was successfully used in 21 consecutive cases for a wide variety of reconstructive techniques with good, functional long-term outcome.

OBJECTIVE: To describe a tenosynoviotomy technique for treatment of sepsis of the digital flexor tendon sheath (DFTS) in horses and report long-term outcome. STUDY DESIGN: Case series. ANIMALS: Horses (n = 9). METHODS: Horses were positioned in lateral recumbency with the affected limb uppermost. A linear incision was made just lateral to the mesotenon beginning 5 cm proximal to the apices of the proximal sesamoid bones, extending 2 cm distal to the bifurcation of the superficial digital flexor tendon (SDFT). The incision was continued through the skin, subcutaneous tissue, palmar/plantar annular ligament, and DFTS. Tenotomy of the distal lateral branch of the SDFT was also performed. The site was thoroughly debrided, lavaged, and packed with gauze and allowed to heal by second intention. Follow-up was obtained via owner telephone interview. RESULTS: Mean surgery time was 32 minutes (range, 10-64 minutes). Systemic antibiotics were administered postoperatively (range, 11-46 days; mean, 23 days). Mean hospitalization was 11 days (range, 0-49 days). Follow-up was available for 7 (70%) horses. One year postoperatively, 5 (71%) horses were serviceable for their intended use, and 2 (29%) had been euthanatized. Of 5 survivors, 3 returned to ridden exercise, 1 was retired as a broodmare, and 1 was a broodmare. All owners were satisfied with the cosmetic appearance of the surgery site. CONCLUSION: Open drainage via tenosynoviotomy, performed as a salvage procedure, represents a feasible treatment for DFTS sepsis.

OBJECTIVE: To describe successful repair of a diaphragmatic hernia in a standing sedated horse using a minimally invasive thoracoscopic technique. STUDY DESIGN: Clinical report. ANIMALS: Warmblood mare with a diaphragmatic hernia. RESULTS: An 18-year-old Warmblood mare with severe colic was referred for surgical treatment of small intestinal strangulation in a diaphragmatic defect. Twelve days after initial conventional colic surgery, left-sided laparoscopy in the standing sedated mare for diaphragmatic herniorrhaphy failed because the spleen obscured the hernia. One week later, a left-sided thoracoscopy was performed in the standing sedated horse and the hernia repaired by an intrathoracic suture technique. No long-term complications occurred (up to 4 years) and the mare returned to her previous athletic activity, followed by use as a broodmare. CONCLUSIONS: To avoid the high risks associated with general anesthesia, and to reduce surgical trauma and postoperative recovery, central diaphragmatic hernias are amenable to repair using a minimally invasive thoracoscopic technique in the standing sedated horse.
