The vascular anatomy of the reverse saphenous conduit flap in cats was denned by contrast radiography of both hindlimbs of 18 feline cadaver specimens. In all 36 flaps, flow of contrast medium from the femoral artery to the distal end of the flap was documented. Direct anastomosis of the superficial branch of the cranial tibial artery with the cranial branch of the saphenous artery and communication of the caudal branch of the saphenous artery with the perforating metatarsal artery, via the medial and lateral plantar arteries, was documented. The cranial branch of the medial saphenous vein was shown to anastomose with the cranial branch of the lateral saphenous vein. The presence of these anastomoses support the feasibility of the reverse saphenous conduit flap as an option for reconstruction of wounds of the metatarsus in cats.  相似文献   

Incidence of post-anaesthetic arrhythmias in the dog     

DARYL D. BUSS  ROBERT E. HESS  ALISTAIR I. WEBB  KAREN R. SPENCER 《The Journal of small animal practice》1982,23(7):399-404

A total of 50 dogs, judged to be free of cardiovascular disease on the basis of physical and electrocardiographic (ECG) examination, underwent ECG monitoring during recovery from general anaesthesia. Fifteen of these dogs (30 per cent) developed some form of cardiac arrhythmia during the recovery period. The arrhythmias most frequently observed were premature ventricular contractions and atrioventricular conduction defects of varying degrees of severity. The observed arrhythmias had ceased by the end of the observation period and did not require specific therapy. There was no apparent correlation between the duration of anaesthesia, the type of medical or surgical procedure and the development of arrhythmias. However, the dogs developing arrhythmias were older than those that did not. The relatively high frequency of occurrence of cardiac arrhythmias must be considered in the evaluation of ECG data from dogs being monitored during recovery from anaesthesia.  相似文献   

The spatial distribution of excreta under intensive cattle grazing   总被引：2，自引：0，他引：2  

I. R. RICHARDS  KAREN M. WOLTON 《Grass and Forage Science》1976,31(2):89-92

The spatial distribution of excreta from intensive cattle grazing was recorded and was described by a negative binomial function. This enabled the proportion of a pasture surface affected by excreta to be calculated for various grazing periods. Where the effect of excreta on the sward was short-lived, as for urine N, or where the total area covered by excreta remained small, as for dung, then little overlapping of effective excreta patches could be expected. Appreciable overlapping of effective patches could, however, occur for the long-lived urine K effect and this should be taken into account when estimating the proportion of a pasture surface affected.  相似文献

Pulse Oximetry in Horses   总被引：2，自引：0，他引：2  

KAREN J. WHITEHAIR DVM    GUY C. G. WATNEY MA  VetMB  PhD  MRCVS    DAVID E. LEITH MD  RICHARD M. DEBOWES DVM  MS  DiplomateACVs 《Veterinary surgery : VS》1990,19(3):243-248

The clinical usefulness of two pulse oximeters was evaluated at two probe sites in nine anesthetized horses. The hemoglobin saturation determined by the pulse oximeters (SaOx) was compared with the hemoglobin saturation calculated from the measured arterial oxygen tension (SaO2). The mean and standard deviation (SD) were calculated from the differences in saturation measurements, over the saturation range of 80% to 100%, for each oximeter used at the tongue probe site and for one oximeter used at the ear. The oximeter results tended to underestimate the SaO2 with mean differences of -3.7% on the tongue and -6.0% on the ear. The limits of agreement were defined as the mean difference +/- 2 SD. Each oximeter used at the tongue produced limits of agreement of +1% to -8%, which meant that 95% of the SaOx values were 1 percentage point above or 8 percentage points below the SaO2. The variability of the differences and limits of agreement were larger when the ear was used as the probe site and at saturations less than 80%. Although both oximeters tended to underestimate the SaO2, they appeared to be clinically useful in detecting changes in arterial hemoglobin saturation.  相似文献   

Clinical Use of Fatty Acid Supplements in Dogs   总被引：1，自引：0，他引：1  

KAREN L. CAMPBELL 《Veterinary dermatology》1993,4(4):167-173

Abstract— Fatty acids in membrane phospholipids are metabolized by cellular enzymes into a variety of eicosanoids that function in the regulation of normal physiology and serve as mediators of inflammation. Fatty acid supplements can alter the types of eicosanoids produced. Many investigations using fatty acids in the treatment of nutritional deficiencies, seborrhea, atopic dermatitis, cardiovascular, neoplastic, ocular and musculoskeletal diseases of dogs have been conducted over the past decade. Additional studies are needed to determine the optimal levels of linoleic acid, gamma-linolenic acid and/or eicosapentaneoic acid in the diets of dogs for the maintenance of normal homeostasis and for the treatment of inflammatory, degenerative and neoplastic diseases.  相似文献   

Feline Onychectomy at a Teaching Institution: A Retrospective Study of 163 Cases     

KAREN SWALEC TOBIAS DVM  MS  Diplomate ACVS 《Veterinary surgery : VS》1994,23(4):274-280

One hundred sixty-three cats underwent onychectomy from January 1985 to November 1992. Onychectomy was performed with guillotine-type nail shears (62%), surgical blade (24.5%), or both (8.6%), and wound closure consisted of bandages alone (61.3%), bandages after suture closure (26.4%), or tissue adhesive application (9.2%). The duration of surgery was significantly longer when onychectomy was performed with a blade or when suture closure was used instead of bandages alone ( P < .05). Fifty percent of the cats had one or more complications immediately after surgery. Early postoperative complications included pain (38.1%), hemorrhage (31.9%), lameness (26.9%), swelling (6.3%), or non-weight-bearing (5.6%), and were observed more frequently after blade onychectomy ( P < .001). Follow-up was available in 121 cats; 19.8% developed complications after release. Late postoperative complications included infection (11.6%), regrowth (7.4%), P2 protrusion (1.7%), palmagrade stance (1.7%), and prolonged, intermittent lameness (0.8%). Late postoperative complications were observed more frequently after shears onychectomy ( P = .018). Use of tissue adhesive was associated with more postoperative lameness ( P < .02) and, when used after shears onychectomy, with more infections ( P = .049).  相似文献
