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.
Prevention of retrosternal adhesions after pericardiotomy. Because repeat sternotomies are becoming much more prevalent with repeat coronary bypass operations, prevention of direct adhesions of the heart and grafts to the back of the sternum by use of synthetic or xenograft material to close the pericardiotomy has become a matter for investigation. In this study bovine and equine glutaraldehyde-processed xenografts were implanted bilaterally in dogs for implant intervals of 6 weeks and 3, 6, 9, and 12 months. The bovine and equine xenografts both performed well in resisting the adhesion of the heart to their inner surfaces and less well in resisting a...
Effects of amitraz, several opiate derivatives and anticholinergic agents on intestinal transit in ponies. Amitraz, atropine, glycopyrrolate and morphine (but not its derivatives, meperidine [pethidine], oxymorphone and butorphanol) produced similar effects on clinically observed intestinal functions and significantly prolonged intestinal transit, as assessed with polyethylene glycol (PEG). However, their mechanisms of action, particularly on intestinal transport (fluid movement), may differ widely. Loperamide appeared to exert a preferential action on intestinal transport rather than motility, as there was no significant delay in PEG transit. The action of amitraz in perturbing smooth muscle coord...
Blunt bovine and equine trauma. During the past 6 years 134 patients were admitted as the result of bovine (cow) and equine (horse) trauma. The mechanism of injury was fall from horse in 45 patients, animal assault in 42, animal kick in 39, and animal-drawn vehicle accident in eight. Injury Severity Score (ISS) ranged from 1 to 41 and was greater than or equal to 25 in 11 patients. One hundred seventeen operative procedures were performed by ten groups of surgical subspecialists. Mortality was nil. Ideal management of these injuries includes treatment in a regional trauma center and an educational program of preventive measu...
Adverse effects following intravenous fluid therapy in the horse using non-commercial fluids: preliminary findings. Non-commercial, endotoxin positive, intravenous fluids as well as a commercially available intravenous fluid were given to clinically normal horses. Endotoxin-positive fluids caused clinical signs attributable to endotoxaemia. Leukopenia, preceded by a fluctuating white cell count, was observed in horses showing clinical signs. The commercial intravenous fluid had no effect on the white cell count or on the clinical state. Precautions to be taken and recommendations are made with regard to the monitoring of horses in which one might be forced to use non-commercial intravenous fluids.
Repair of a fracture of the deltoid tuberosity of the humerus in a pony. ALTHOUGH diaphyseal and distal metaphyseal fractures of
the equine humerus have been discussed in the literature
(Johnson, Lowe, Fessler and Amstutz 1974; Vaughan and
Mason 1975; Turner 1984), reports of humeral fractures of
other configurations are rare. Allen and White (1984) described
the successful surgical treatment of a chip fracture of the greater
tubercle of the humerus. This report describes the clinical
features and treatment of a fracture of the deltoid tuberosity.
Diagnostic ultrasound in equine reproduction. This article reviews the type of equipment available, the examination techniques, and the interpretation of information derived from ultrasound in broodmare practice. The application of diagnostic ultrasound has found immediate acceptability and clinical usefulness in the genital evaluations of the broodmare.
Diseases of the liver. The ability to image the liver in horses can add valuable diagnostic information or aid in guided biopsy procedures. Anytime the size, shape, position, and texture of the liver can be determined, additional information about the horse's condition is gained. Conditions such as cholelithiasis, neoplasia, fibrosis can be detected ultrasonographically.
Uses of ultrasound in equine internal medicine. Ultrasound examination allows the diagnostician to examine peripheral soft tissues and many internal organs in a noninvasive manner. In most instances, ultrasound can be utilized to complement other diagnostic aids, but its increased use has revealed the unique advantages of this technique over more established diagnostic tools. The ease with which ultrasound interpretation can be learned and the increased availability of instruments make this approach to diagnosis a valuable asset in the diagnosis of many equine medical diseases.
General considerations for ultrasound examinations. Patient preparation and restraint, instrumentation, and methods of retaining records of ultrasound images are discussed.
Ultrasound science for the veterinarian. In order to successfully sort out the information, both real and bogus, in an ultrasonic image, one must have a fundamental understanding of the physical and electronic events that produced the image. We have looked at the basic science, signal processing, some case examples of ultrasound science in practice, and some popular illusions. It is a good starting place for the newcomer to ultrasonic imaging.
Lung sounds in cattle, horses, sheep and goats. The purpose of this paper is to emphasize the importance of pulmonary auscultation for the clinician. It suggests a clarification and simplification of the terminology to be used which would be helpful to veterinary students and allow better communications between veterinarians. The interpretation of these sounds and the relationships to conditions and diseases of the lungs in cattle, horses, sheep and goats are discussed.
Ultrasonographic appearance and correlative anatomy of the soft tissues of the distal extremities in the horse. The diagnostician should be familiar with the normal ultrasound appearance (size, shape, position, and textural quality) of each structure examined. With these factors as reference points, one can describe lesions in the structure involved, the precise location and extent of the lesions, and the degree of structural compromise that is manifested. Documentation of lesions of tendons and ligaments enables one to make an accurate diagnosis and a more precise prognosis. Serial examination during the healing phases allows for a more accurate prediction as to when the structure in question can withs...
Diagnostic ultrasonography of equine limbs. In our 3 years of clinical experience, we have found that diagnostic ultrasound provides the veterinarian with a valuable diagnostic tool. It allows the clinician to quantify morphologic change that has occurred as a result of soft-tissue injuries, even when the clinical findings are ambiguous or insufficient. In cases in which aggressive postinjury therapy has been instituted prior to presentation, diagnostic ultrasound is often the only noninvasive method that can ascertain the extent of the horse's injury. Diagnostic ultrasound provides the technology to detect injuries before they become p...
Guidelines for the recognition and assessment of pain in animals. Prepared by a working party of the Association of Veterinary Teachers and Research Workers. Despite some views to the contrary the working party of the Association of Veterinary Teachers and Research Workers considers that it has been demonstrated that it is possible to prepare guidelines for the recognition and assessment of pain in experimental animals. The detailed information readily available on species specific signs is limited and it has been particularly difficult to obtain such signs for the smaller mammals and for the non-mammalian species.
Temporary bilateral carotid artery occlusion as an aid to nasal surgery in the horse. One of the major obstacles to successful intranasal surgery in the horse is haemorrhage, even minor interferences causing profuse bleeding. Conventional techniques for haemostasis are ineffective or inhibit the progress of the surgery. Temporary bilateral occlusion of the common carotid artery resulted in a substantial reduction in haemorrhage during intranasal surgery in five horses, with much improved visibility and facility of operation. The large contribution to the circle of Willis by the ventral spinal artery is believed to prevent cerebral ischaemia during this procedure. This paper des...
Pulmonary function in the horse during anaesthesia: a review. The effect of abnormal body position on cardiovascular and pulmonary function in the awake and anaesthetised horse is reviewed. Parameters such as pulmonary shunt, lung volumes, blood gases and alveolar-arterial oxygen partial pressure differences are discussed. Withholding food for 24 hours and mechanical ventilation may be used to improve blood gas values associated with abnormal recumbency during anaesthesia. During prolonged recovery, horses should be encouraged to adopt sternal recumbency.
Hernia repair in a horse. The repair of a large defect in the abdominal wall of an American Saddlehorse by implantation of a polypropylene monofilament mesh.
Periorbital skull fractures in five horses. Periorbital skull fractures were diagnosed in 5 horses, and were associated with ophthalmic complications including corneal ulceration, uveitis, and entrapment of the eye by retrobulbar bone fragments. Physical examination was of greater diagnostic use than radiography. Surgical repair was performed on all horses and was associated with a more favorable postoperative appearance in horses treated acutely; however, the cosmetic results were considered acceptable in all horses. Major postoperative complications were not observed.
