Treatment of equine leg wounds using skin grafts: Thirty-five cases, 1975-1988          下载免费PDF全文

French DA  Fretz PB 《The Canadian veterinary journal. La revue veterinaire canadienne》1990,31(11):761-765

A retrospective study was conducted on 35 equine patients with lower leg wounds that were managed utilizing skin graft procedures. Two pinch graft, five punch graft, seven tunnel graft, eight split-thickness mesh graft and thirteen full-thickness mesh expansion graft procedures were performed in the initial treatment. The average wound size was 188 cm². Twentyfour cases had pregrafting complications: 10 wounds developed sequestra; three wounds were grossly contaminated and infected; and 11 cases developed granulation tissue complications prior to grafting. Graft failure following the initial procedure was seen in 12 cases and occurred with all techniques except pinch grafting. Graft failure was often attributable to poor quality of granulation tissue as well as anatomic site, especially the dorsal surface of the tarsus. An average of two additional grafting procedures was required to successfully treat initial failures. Pinch grafts took the longest time to epithelialize (70 days), followed by punch grafts (47 days). Both were similar in terms of being the least durable and least cosmetically acceptable of all techniques used. Split-thickness and full-thickness mesh expansion grafts were technically the most difficult, but showed the most rapid epithelialization (28 days), greatest durability, and the best cosmetic appearance. Tunnel grafts provided a practical technique for grafting cases which were either not suited for, or which had failed with, mesh expansion grafts.  相似文献

A dorsal approach for the removal of the nasal septum in the horse     

Shoemaker RW  Wilson DG  Fretz PB 《Veterinary surgery : VS》2005,34(6):668-673

OBJECTIVE: To describe and evaluate a technique involving a dorsal approach for the removal of the nasal septum in adult horses. STUDY DESIGN: Retrospective clinical study. ANIMALS: Four client-owned horses. METHODS: Access for partial nasal septum resection was through a dorsal nasal bone flap. Septum resection was performed because of reduced airflow from septal deviation and/or thickening caused by traumatic insult or neoplasia. Preoperative clinical signs and diagnostic results were recorded. Intra- and postoperative complications were noted and follow-up information was obtained from telephone interviews of owners or by clinical examination. RESULTS: The abnormal segment of the nasal septum was completely removed in all horses. A dorsal nasal bone flap approach provided excellent access to the septum and allowed immediate control of hemorrhage; blood transfusion was not needed. Cosmetic results were considered good to excellent by owners and horses returned to their previous level of work without perceived limitations associated with airway function. CONCLUSIONS: Nasal septum resection by the dorsal approach permits good observation of the abnormal septum, and provides exposure that facilitates removal of nasal masses and reduction of depression fractures with minimal complications. CLINICAL RELEVANCE: A dorsal nasal bone flap approach should be considered for horses that require nasal septum resection because it can be achieved with minimal hemorrhage, good cosmetic results, and return to function.  相似文献

Attempts at surgical correction of unusual colonic fistulae in the horse     

Bailey JV  Fretz PB 《The Canadian veterinary journal. La revue veterinaire canadienne》1983,24(7):222-223

Two incidents of penetrating wounds into the abdominal cavity of horses are presented. In both events these had resulted in penetraton of the intestinal tract. Both animals had received only minimal veterinary attention in the acute stage and had survived with the formation of intestinal fistulae.

Attempts at surgical repair resulted in failure in one animal and in closure of the fistula in the second with some subsequent cosmetic defect.

Herbicide-impregnated mulches for weed control in container nursery stock     

Thomas A. Fretz 《Scientia Horticulturae》1973,1(2):165-170

Isopropyl-m-chlorocarbanilate (chlorpropham), chlorpropham plus p-chlorophenyl-N-methylcarbamate (PPG-124), S-ethyl dipropylthiocarbamate (EPTC), N,N-dimethyl-2,2-diphenylacetamide (diphenamid) and 2,6-dichlorobenzonitrile (dichlobenil) were evaluated for plant tolerance and weed control when incorporated on milled pine bark mulch and applied at a depth of 1.27 cm to five species of container-grown nursery stock. During two seasons, all impregnated mulches except EPTC at 5.6 kg/ha and diphenamid at 5.6 kg/ha provided adequate long-season broadleaf weed control. Similarly, long-season grass weed control was acceptable with all herbicide-impregnated mulches except chlorpropham at 2.2 kg/ha, chlorpropham plus PPG-124 at 2.2 plus 0.4 kg/ha and diphenamid at 5.6 kg/ha. Plant injury appeared on all five species of nursery stock when dichlobenil was impregnated on pine bark mulch at a rate of 13.4 kg/ha.  相似文献

Removal of a retropharyngeal foreign body in a horse, with the aid of ultrasonography during surgery   总被引：1，自引：0，他引：1  

D A French  J W Pharr  P B Fretz 《Journal of the American Veterinary Medical Association》1989,194(9):1315-1316

Diagnostic ultrasonography was used during surgery to assist in the removal of a piece of wire from the retropharyngeal region. A 3-year-old Quarter Horse mare was referred with dysphagia of 2 days' duration. Radiography revealed a 9-cm piece of wire located caudodorsal to the larynx. A ventral surgical approach was performed, dissecting along the right side of the larynx and trachea. The surgical field was filled with 0.85% sterile physiologic saline solution. A 5 MHz-mm sector scanner probe immersed in the fluid was able to locate the wire and facilitate the direction and depth of dissection to where the wire was identified and removed.  相似文献   

Further comparison of faecal egg count reduction test procedures: Sensitivity and specificity     

PB McKenna 《New Zealand veterinary journal》2013,61(6):365-366

Extract

In a recent communication (McKenna2006 McKenna, PB. 2006. A comparison of faecal egg count reduction test procedures. New Zealand Veterinary Journal, 54: 202–3. [Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]), a comparison was made between four different methods for calculating results from faecal egg count reduction (FECR) tests (FECRTs). The first and most complex of these, referred to as FECRT₁, involved the use of the formula: FECR = 100 × (1?[T2/T1][C1/C2]), where T1 and T2 represented the mean pre- and post-treatment faecal nematode egg counts (FECs) of a treated group, and C1 and C2 represented the mean pre- and post-treatment FECs of an untreated control group, respectively. The other three formulae consisted of more simplified versions of this procedure. In one of them (FECRT₂), only post-treatment samples were considered, whereas the other two were based on comparisons between the FECs of groups of animals sampled at the time of anthelmintic treatment (pre-treatment) with those sampled several days later (post-treatment). Thus, FECRT₂ was determined according to the formula: FECR = 100 × (1?[T2/C2]), while FECRT₃ was calculated from FECR = 100 × (1?[T2/T1]). The fourth procedure (FECRT₄) was based on a further simplification of FECRT₃ where pre-treatment FECs from only one treatment group were used for comparison with all post-treatment results. This base-line pre-treatment group thus effectively functioned as an untreated control group and hence the formula for FECRT₄ was FECR = 100 × (1?[T2/C1]).  相似文献
