Topic:Veterinary Practice
Veterinary practice in relation to horses encompasses the medical care, management, and treatment of equine species. This field involves various aspects of equine health, including preventive care, diagnosis, and treatment of diseases, surgical interventions, and emergency care. Equine veterinarians employ a range of diagnostic tools and techniques such as physical examinations, imaging, and laboratory tests to assess and monitor horse health. In addition to addressing physical ailments, veterinary practice also includes nutritional management, reproductive health, and performance-related issues. This page compiles peer-reviewed research studies and scholarly articles that explore the methodologies, advancements, and outcomes in veterinary practices specific to equine health.
Accuracy of clinicians in predicting site and type of lesion as well as outcome in horses with colic. To assess the ability of clinicians to predict the site and type of lesion as well as outcome in horses with colic. Methods: Prospective case study. Methods: 139 horses admitted for evaluation of signs of colic. Methods: Six interns and residents examined horses with colic and predicted the segment of intestine that was affected, the type of lesion, and whether the horse would survive to discharge. Accuracy of prediction of site and type of lesion and survival prediction was compared between the first and second halves of the year, using chi 2 analysis and 95% confidence intervals on sensitivi...
Evaluation of endocrine function. This article outlines strategies on how to approach equine endocrine disorders based on clinical signs and clinical pathologic data. In the 1987 Veterinary Clinics of North America: Equine Practice article on evaluating equine endocrine function, Beech stated that the numbers of hormonal assays available to use in horses was limited. Unfortunately, not much has changed since then. With the advent of convenient assay kits for many hormones and cofactors available in human medicine, it is possible to submit samples to laboratories for measurement of a wide range of endogenous substances. Caution...
Diagnostic and forensic toxicology. In most competent veterinary diagnostic laboratories, analytical findings are interpreted by the veterinary toxicologist to determine the significance of the finding in view of historic, clinical, and pathologic findings. A veterinary toxicologist also will provide consultation about possible toxic rule-outs for a case, treatment of affected animals, and prevention of additional cases. Once all of the information is available, a complete summary of the findings can be provided to the client. When the procedures outlined are followed, including a systematic approach to collecting all the eviden...
Abnormalities in oxygenation, coagulation, and fibrinolysis in colonic blood of horses with experimentally induced strangulation obstruction. To measure arterial and venous blood gas, coagulation, and fibrinolysis variables in blood from isolated segments of control and ischemic large colons for the purpose of identifying variables for rapid, indirect assessment of colonic mucosal injury. Methods: Variables were determined at specific intervals during the 4-hour study (3 hours of ischemia and 1 hour of reperfusion). Methods: Seven clinically normal horses between 2 and 15 years old. Methods: Horses underwent laparotomy and occlusion of the lumen and vasculature of the mid-portion of the pelvic flexure of the large colon. During isch...
Ventral abdominal approach for laparoscopic ovariectomy in horses. Eleven mares and four mules were ovariectomized by a ventral abdominal laparoscopic technique. This approach required tilting the operative table about 30 degrees elevating the pelvis to allow observation of the ovaries. A triangulation technique with a single laparoscopic portal and four instrument portals was used. The ovarian pedicles were ligated and the ovaries were removed through a single enlarged instrument portal. Females ranged in age from 5 months to 18 years. Mean operative time was 44 minutes (range 20 to 90 minutes); mean operative time of the last seven animals was 26 minutes. S...
Equine pulmonary disease: a case control study of 300 referred cases. Part 4: Treatments and re-examination findings. One-hundred and forty-seven of 270 (54.4%) horses suffering from pulmonary disorders were given at least one re-examination including, clinical, bronchoscopic, pulmonary function and cytological examinations after treatment and a further 83 of these horses (30.7%) had their clinical progress assessed by verbal or written reports. These examinations and progress reports showed high levels of partial or total recovery for most pulmonary disease categories, including chronic obstructive pulmonary disease, infectious, S. zooepidemicus and undifferentiated pulmonary disease and lungworm infection g...
[Sonographic diagnosis (B-mode technique) for the eyes in horses. 1. Methods and normal findings]. In this presentation, normal sonoanatomy of the horse eye will be introduced and biometrical data of 30 healthy eyes along optical axis will be presented. We used the ultrasound system Philips Diagnost R 1200 in connection with a 5 MHz linear transducer. With this equipment it is possible to visualize and measure at the unaltered eye the cornea, the anterior chamber of the eye, ciliary body, iris, lens, vitreous body, wall of the posterior globe (retina, choroid, sclera) and retrobulbar structures (optical nerve, retrobulbar muscles, orbital fat pad, bony orbita). The echographical examination...
Suture sinus formation following closure of ventral midline incisions with polypropylene in three horses. Suture sinuses formed in 3 horses following closure of ventral midline incisions with size-2 polypropylene. Suture sinuses healed after the suture material was removed. Suture sinus formation following closure with polypropylene may be related to the suture material's mechanical, rather than its chemical, properties. If polypropylene is used to close the linea alba in horses, the amount of tissue incorporated in the suture loops, suture tension, and knot volume should be minimized to decrease the risk of suture sinus formation.
Management of penetrating joint injuries. A classification scheme for penetrating joint injuries is presented. Diagnostic techniques and treatment recommendations for managing penetrating joint injuries in small animals are described. Techniques used in human and equine patients are discussed for comparison.
Use of intraoperative ultrasonography in six horses. Intraoperative ultrasonography was used in six horses to aid localization and removal of bone fragments (3 horses) and foreign bodies (3 horses). The ultrasound transducer was enclosed in a sterile sleeve containing sterile aqueous gel and the examination was performed after aseptic preparation of the surgical site. Using ultrasound guidance a needle was placed in contact with the bone fragment or foreign body and an incision was made along the path of the needle to expose and remove the object. This technique resulted in decreased operative time and minimal tissue dissection.
Partial excision of the clavicle for nonunion in National Hunt Jockeys. National Hunt jockeys suffer a disproportionate number of clavicular fractures and their return to riding may be considerably delayed by refracture and symptomatic nonunion, with obvious implications. We report six such cases in which excision of the clavicular fragment distal to the fracture was associated with an early return to work and no recurrent injury to the shoulder.
Echocardiography. Echocardiography encompasses a number of specific imaging techniques. The two-dimensional (2-D) echocardiogram is used to identify lesions of the heart and great vessels, assess myocardial function and provide a template for guiding contrast echocardiography, colour-coded Doppler echocardiography and spectral Doppler studies. M-mode echocardiography is used to measure cardiac size and ventricular function and can be combined with contrast or colour-coded Doppler studies for accurate timing of flow events. Pulsed wave and continuous wave Doppler echocardiography display the direction and veloci...
Heart murmurs in horses: determining their significance with echocardiography. Physiological flow murmurs occur frequently in horses and may be difficult to distinguish from murmurs associated with underlying cardiac disease. The significance of heart murmurs auscultated in horses is often difficult to determine if the horse is not exhibiting any clinical signs or if the signs, such as poor performance, are nonspecific. A complete echocardiographic examination (M-mode, 2-dimensional (2-D) and Doppler) provides an objective assessment of the severity of the horse's underlying cardiac disease. Valvular regurgitation and ventricular septal defects (VSDs) occur frequently an...
Ultrasound-guided transection of the accessory ligament of the deep digital flexor muscle (distal check ligament desmotomy) in horses. Transection of the accessory ligament of the deep digital flexor muscle (distal check ligament desmotomy) was completed in 44 horses using an ultrasound-guided technique. The technique used real-time ultrasound with a 7.5 MHz transducer to observe the dissection and isolation of the check ligament through a 1 to 1.5 cm incision and to check for complete transection of the check ligament. The technique was effective in correcting flexural deformity of the distal interphalangeal joint and the metacarpophalangeal joint in all but three horses. Check ligament desmotomy at a young age (median, 6 mo...
Value of skin testing for predicting reactions to equine rabies immune globulin.
Clinical infectious diseases : an official publication of the Infectious Diseases Society of America
The high cost of postexposure prophylaxis for rabies is one reason that treatment is inadequate in developing countries. This problem has kindled interest in the use of equine rabies immune globulin, which is a less expensive, yet effective, substitute for human rabies immune globulin. Fatal anaphylaxis is a feared complication of the administration of heterologous serum; therefore, authoritative sources recommend prior skin testing. However, recommendations for methods of administering such a skin test and for its interpretation vary greatly. We embarked on a long-term study to develop guidel... Ligaments associated with joints. This article contains a short introduction to the anatomy, physiology, and pathophysiology of ligaments associated with diarthrodial joints. Individual ligaments are discussed on a regional basis as forelimb, distal limb, and hindlimb. Emphasis is placed on the anatomy of the ligaments because this is the key to sound clinical application of their involvement in joint disease. There are few conditions of diarthrodial joints that do not involve their associated ligaments, and this role may be in causative, diagnostic, and therapeutic or convalescent considerations.
Repair of a full-thickness gastric rupture in a horse. A 14-year-old Thoroughbred broodmare was evaluated for signs of mild to moderate abdominal pain of 5 hours' duration. Exploratory celiotomy revealed a 20 x 8-cm subserosal hematoma associated with a focal serosal perforation overlying a muscular tear along the parietal surface of the stomach. The odor of intestinal tract gas was detected, but gross contamination of the abdomen was not evident. Concurrent partial volvulus of the small intestine was evident. Removal of the large colon from the abdomen appeared to coincide with propagation of the serosal perforation to a full-thickness gastric re...
Infectious tenosynovitis. Infectious tenosynovitis is treated similarly to infectious arthritis. The principles of treatment include an early diagnosis and immediate therapy. Therapy should include use of systemic and local antimicrobials and sheath lavage and drainage. Fibrosis and adhesions can be minimized with passive range of motion exercises, intrathecal hyaluronate, and phenylbutazone therapy. Restrictive fibrosis may be treated successfully by annular ligament resection.
Uterine torsion associated with small intestinal incarceration in a mare at 126 days of gestation. A mare at 126 days of gestation was examined because of signs of abdominal pain. The cause of abdominal pain could not be determined by physical examination. Lack of response to analgesics and small intestinal distention on palpation per rectum prompted exploratory celiotomy. Small intestine was found to be entrapped by the uterus, which had undergone torsion. The uterus was returned to its correct position, and the small intestine was decompressed. After surgery, the mare was treated with orally administered progestin to prevent abortion. The mare recovered and delivered a live foal at 354 da...
