ObjectiveTo determine if lactate concentrations in jugular venous and auricular arterial blood differ in anesthetized sheep.Study designProspective, controlled experimental study.AnimalsTwelve healthy adult ewes, 4–7 years and weighing 62–77 kg.MethodsJugular venous blood was collected before anesthesia (PreO_v) for measurement of lactate concentration, packed cell volume and total protein. Ewes were administered a standard anesthesia protocol. Jugular venous (IntraO_v) and auricular arterial (IntraO_a) blood samples were obtained 40 minutes after induction of anesthesia, and again in recovery (PostO_v and PostO_a). An additional blood sample was drawn 6 weeks post-operatively from non-fasted sheep (NF_Lact). Lactate concentrations were compared among PreO_v, IntraO_v and IntraO_a, PostO_v and PostO_a, and between PreO_v and NF_Lact with paired t-test and repeated measure analyses of variance (anova) with PreO_v as a covariate (p = 0.05).ResultsIntraO_v lactate concentration had decreased from PreO_v There were significant differences between arterial and venous IntraO and PostO lactate concentrations. There was no significant difference between IntraO and PostO, or PreO_v and NF_Lact.Conclusions and clinical relevanceLactate concentrations were significantly lower in anesthetized sheep compared to non-anesthetized sheep. Lactate concentrations in venous blood were higher than in arterial blood. Therefore, anesthetic status and sampling site should be considered when interpreting lactate concentrations, and the sampling site should be consistent for repeated measurements.  相似文献   

Introduced ticks and tick-borne diseases: the threat and approaches to eradication.     

John E George  Ronald B Davey  J Mathews Pound 《Veterinary Clinics of North America: Food Animal Practice》2002,18(3):401-16, vi

Exotic tick species and tick-borne diseases are serious threats to live-stock, companion animals, and wildlife in the United States. Recurring introductions of exotic tick species into the United States are a significant indicator of the degree of risk. Successful tick-eradication campaigns, such as the national program that eradicated Boophilus annulatus and B. microplus from the United States, the Cattle Fever Tick Eradication Program of the US Department of Agriculture's Veterinary Services that protects against the re-entry and dissemination of Boophilus ticks from Mexico back into their former haunts in the southern states, and the eradication action that eliminated Rhipicephalus evertsi from a game park in Florida, are sources of useful information that aid in elucidating essential elements of successful eradication programs. Examples of failed eradication programs in places such as Puerto Rico and St. Croix also have heuristic value. Among the varieties of tick species and related infectious agents that threaten the United States, Boophilus ticks and bovine babesiosis, Amblyomma species (especially the tropical bont tick) and heartwater, and equine babesiosis, for which endemic vectors exist, are of special concern. Risk assessments to accumulate, evaluate, and synthesize information needed to appraise risks, consequences, and preparedness are necessary not just to inform federal, state, and local officials, as well as producers and stakeholders, but also to facilitate the creation of emergency response plans.  相似文献

Surgery of the canine vagina and vulva.     

K G Mathews 《Veterinary Clinics of North America: Small Animal Practice》2001,31(2):271-290

Accurate diagnosis of canine vaginal abnormalities often requires general anesthesia, vaginoscopy, and contrast radiography. Abdominal ultrasonography, thoracic radiography, computed tomography, and histopathology may also be advised for the workup of mass lesions before surgery. Many procedures such as episioplasty and resection of pedunculated vaginal masses or edematous tissue are easily performed with proper planning and equipment (e.g., electrocautery). Consideration should be given to referring more complicated procedures such as resection of large vaginal masses or vaginal stenoses to a board-certified surgeon. Finally, preoperative placement of a fentanyl patch and pre- or postoperative epidural analgesia are highly recommended for any vulvovaginal surgical procedure.  相似文献   

Cyclosporin treatment of perianal fistulas in dogs.          下载免费PDF全文

K A Mathews  S A Ayres  C A Tano  S M Riley  H R Sukhiani    C Adams 《The Canadian veterinary journal. La revue veterinaire canadienne》1997,38(1):39-41

The purpose of this pilot study was to investigate the efficacy of cyclosporin in treating perianal fistulas (PAF) in dogs. Based on resolution of all fistulas in all dogs with remission times up to > 18 months, we conclude that cyclosporin therapy is the treatment of choice for PAF in dogs.  相似文献
