摘要:

To correlate the results of anin vitrostudy with clinical response, the effects of 0.005 and 0.05% chlorhexidine diacetate and 0.1 and 1.0% povidone‐iodine concentrations on wound healing were evaluated in five beagle dogs. Full‐thickness skin wounds (2 × 2 cm) were irrigated once daily for 14 days with the antiseptic solutions or physiologic‐buffered saline. Chlorhexidine diacetate 0.05% had significantly more bactericidal activity than povidone‐iodine and saline, and both chlorhexidine diacetate concentrations had residual effects 6 hours after irrigation. Neither povidone‐iodine nor saline had significant bactericidal activity. The percentages of unhealed wound area and wound contraction were calculated 7, 14, and 21 days after wounding. Healed wound area and contraction were similar in wounds treated with chlorhexidine diacetate and povidone‐iodine. However, wounds treated with chlorhexidine diacetate had more healed wound area on days 7 and 14 and more contraction on days 7, 14, and 21 than saline‐treated wounds. At the concentrations tested, chlorhexidine diacetate irrigations provided bactericidal activity and were more beneficial to wound healing than irrigations with saline alone. These results suggest that concentrations of chlorhexidine diacetate which are cytotoxic to tissue culture fibroblastsin vitrodo not interfere with wound

摘要:

A technique for localizing the canine hypophysis regardless of the shape or size of a dog's skull was evaluated. Using known anatomic landmarks, the approximate location of the hypophysis was estimated, and three small self‐threading screws were placed as radiographic markers in the exposed sphenoid bone. A cranial sinus venogram was performed and the hypophysis was outlined by the contrast‐filled cavernous sinus. A circular osteotomy was centered over the hypophysis, using the previously placed screws as reference points. The technique was evaluated in eight dogs in a nonsurvival procedure. In seven dogs, hypophysectomy was complete and the osteotomy sites were centered precisely over the hypophy

摘要:

Fecal incontinence was created by bilateral pudendal neurectomy in 12 dogs. In six dogs, the fecal incontinence was treated by implantation of a polyester‐impregnated silicone elastomer sling to form an artificial external anal sphincter. Six dogs underwent the same operative procedure without the implant to serve as controls. Five dogs regained total continence and one dog regained partial continence after implantation of the sling. Four control dogs remained incontinent and two control dogs regained partial continence. The difference between the dogs with slings and the controls was statistically significant (p<0.01). The only complication was infection in one dog, which was treated successfully. Histologic reaction to the implant was confined to a zone of fibrosis 1 to 3 mm surrounding the implant. The sling was well tolerated clinically and appeared to offer a successful method for correction of fecal incontinence in dog

摘要:

An axial pattern flap based on the superficial brachial artery and vein (brachial axial pattern flap) was developed on the forelimbs of five dogs. The flap was immediately transferred to a distal cutaneous defect created on the antebrachium of that limb. A control flap was elevated on the opposite limb and transferred to a similar distal site after ligation of the superficial brachial artery and vein at the base of the flap. Mean brachial axial pattern flap survival (98%) was significantly more than mean control flap survival (77%) (p<0.05). Results of this study suggest that the brachial axial pattern flap has potential application for closure of major cutaneous defects involving the canine antebrachium above the carpus.

摘要:

Postoperative laryngeal webbing in four dogs was corrected with a mucosal flap technique using mucosa harvested from the lateral wall of the laryngeal ventricle. Airway obstruction caused by the webbing was relieved in all dogs. Follow‐up time was 3 months to 5 years. The technique allowed mucosal apposition without undue tension on the suture lin

摘要:

Twenty‐three canine pelves were tested bilaterally to determine the stiffness and strength of intact ilium and stabilized oblique iliac osteotomies that simulated a common clinical fracture. Fixation systeMS tested were three 4.0 mm cancellous screws inserted ventral to dorsal across the osteotomy site and one laterally placed five hole 3.5 mm dynamic compression plate. Specimens were mechanically tested to failure under torsional, axial, or axial plus bending loads. Lag screw fixation was stiffer and stronger than plate fixation in all testing modes. The differences were statistically significant (p<.05) in the torsional and axial plus bending loading modes. Fatigue testing was performed on implanted specimens with low‐level cyclic loading under axial plus bending loading conditions. Physiologic loading conditions failed to produce mechanical failure of either fixation system after 100,000 cyc

摘要:

A combined tension band and lag screw technique for fixation of olecranon osteotomies was used in six canine clinical patients weighing 4.5 to 19 kg. After the proximal part of the ulnar shaft was exposed, a screw hole was drilled and tapped just cranial to the caudal cortex of the olecranon. An osteotomy was performed and the hole in the olecranon fragment was overdrilled to form a gliding hole. For reconstruction, the olecranon was reduced anatomically and compressed with a screw placed in lag fashion. With the trochlear notch exposed, a Kirschner wire was inserted cranial to the screw, using care not to enter the elbow joint. A double‐twist figure‐eight tension band wire was placed around the Kirschner wire in five dogs and around the screw in one dog. In this dog, a spiked washer was used with the screw because a small olecranon fragment had been produced by incorrect osteotomy position. A painful soft tissue swelling over the prominent washer, which resolved after implant removal, was the only complication attributed to the technique. The combined tension band wire and lag screw technique was a rapid and reliable method for fixation of olecranon osteotom

摘要:

A retrospective study was made of 75 mandibular fractures in 62 cats. Mandibular fractures comprised 14.5% of all fractures seen in 517 cats. Automobile trauma was the cause of injury in more than 50% of the cases. The mean age of patients was 29.5 months. Symphyseal fractures were most common (73.3%), followed by fractures of the body (16%), condyle (6.7%), and coronoid process (4%). Sixty‐seven percent of the fractures were stabilized. Cerclage and interfragmentary wiring were the most common forMS of fixation. Antibiotics were administered to 73.6% of the patients. Complications were reported in 24.5% of the cats. Malocclusion and soft tissue infections were the most frequent complications. Complications developed more commonly in cats with multiple or open fractures. Clinical union occurred by an average of 6 weeks (range, 3–12 weeks) for symphyseal fractures, 10 weeks (range, 8–16 weeks) for body fractures, 6 weeks for coronoid fractures, and 6 weeks (range, 4–8 weeks) for condylar fr
