Topic:Veterinary Procedure
Veterinary procedures in horses encompass a range of medical and surgical interventions performed to diagnose, treat, and manage equine health conditions. These procedures are designed to address various health issues, from routine care to emergency interventions. Common veterinary procedures include vaccinations, dental care, lameness evaluations, reproductive services, and surgical interventions such as colic surgery or fracture repair. This page compiles peer-reviewed research studies and scholarly articles that explore the methodologies, outcomes, and advancements in veterinary procedures for horses, providing insights into their application and efficacy in equine medicine.
Surgical correction of an equine deviated anterior maxilla. The surgical correction of midfacial deformities of the horse have rarely been undertaken. This article describes the successful management of a submucous cleft of the maxilla in a young colt. Details of the operative and perioperative medical and surgical management are described. The horse, now 5 years of age, has sired eight normal progeny.
[A horse with grass sickness]. A three year old warm-blood gelding with severe colic was referred to a veterinary clinic. The history revealed that the horse was found early in the morning with severe colic, and laying in the pasture. On arrival the clinical examination showed a complete wet horse with a pulse rate of 92/min, a respiratory rate of 24/min., a pcv of 0.50 L.L.-1, a T. of 38.0 degrees C, and no gastric reflux. Rectal examination revealed a sticky rectal mucous membrane and a colonic impaction together with displacement of the large colon. A diagnostic laparotomy showed an impaction as is seen in horses with Gr...
Clinical effects of detomidine with or without atropine used for arthrocentesis in horses. The effectiveness of detomidine with or without atropine sulfate premedication in producing sedation and analgesia for arthrocentesis was studied in 12 horses. The effects were evaluated by monitoring heart and respiratory rates, borborygmi, distance from the lower lip to the floor, systolic blood pressure, and response to needle insertion. Either atropine or saline (as a placebo) was administered immediately prior to detomidine. All drugs were administered intravenously. Measurements were taken prior to drug injection and at 1, 5, 10, 15, 20, 25, 30, 40, 50, 60, 120, 180 and 240 minutes posti...
Proceedings of the John P. Hughes International Workshop on Equine Endometritis. Davis, California, August 1992. The paper is a report from a workshop discussing equine endometritis, a condition affecting horse fertility. The event was held in honor of Professor John Hughes and his significant contributions […]
[Anorexia in a pony with Cushing’s disease]. An eighteen-year-old pony gelding was referred to the Faculty of Veterinary Medicine because of colic, due to cecal tympany. His haircoat was dull with long wavy hair. After medical treatment of the colic it was sent home three days later. Just before it had been dismissed the morning plasma glucose concentration measured 10.2 mmol.l-1. The basal plasma cortisol concentration was high (180 nmol.l1) and basal plasma ACTH concentration was highly elevated (> 960 pg.ml1). An ACTH-stimulation test was performed by intravenous administering of 0.25 mg synthetic ACTH 1 24 at 9.00 hours showing ad...
Use of flow-volume loops to evaluate upper airway obstruction in exercising standardbreds. Flow-volume loops generated from 6 Standardbreds at rest and during treadmill exercise were evaluated for their use in detecting upper airway obstruction. Tidal breathing flow-volume loops (TBFVL) were obtained from horses at rest and exercising at speeds corresponding to 75% of maximal heart rate and at maximal heart rate. The TBFVL were evaluated, using a pulmonary function computer; calculated indices describing airflow rate and expiratory-to-inspiratory airflow ratio for individual loops were determined. In addition to TBFVL indices, standard variables of upper airway function also were me...
Assessment and treatment of equine humeral fractures: retrospective study of 54 cases (1972-1990). Fractures of the humerus were diagnosed in horses at The Ohio State University Veterinary Teaching Hospital. Twenty-four horses (44.4%) were destroyed after radiographic assessment (mean age of 5.0 years). Surgical treatment was elected in 13 horses (24.1%, mean age of 0.42 years). Conservative management, consisting of prolonged stall rest, was chosen for 17 horses (31.5%, mean age of 2.2 years). In the surgically treated group, 3 foals (23.1%) all less than 2 months of age at the time of fracture and treated with intramedullary stack pinning, survived and became athletically sound. After con...
Focal exocytosis by eosinophils–compound exocytosis and cumulative fusion. We have investigated the granule fusion events during exocytosis in horse eosinophils by time-resolved patch-clamp capacitance measurements. Stimulation with intracellular GTP gamma S leads to a stepwise capacitance increase by 4.0 +/- 0.9 pF. At GTP gamma S concentrations < 20 microM the step size distribution is in agreement with the granule size distribution in resting cells. Above 80 microM the number of steps is reduced and very large steps occur. The total capacitance increase, however, is unaffected. These results show that at high GTP gamma S concentrations granule--granule fusion o...
Immunoaffinity chromatography combined with gas chromatography-negative ion chemical ionisation mass spectrometry for the confirmation of flumethasone abuse in the equine. Immunoaffinity chromatography using a synthesised immunosorbent was used to extract tritiated dexamethasone (with dexamethasone carrier) from equine urine at a recovery of 81.7 +/- 8.4% (mean +/- S.D.). A method utilising this procedure coupled to cool on-column injection gas chromatography-negative ion chemical ionisation mass spectrometry is also described for the confirmation of low levels of flumethasone in equine urine samples.
Rhabdomyosarcoma of the tongue in a horse. A 5-year-old Quarter Horse mare was examined because of a 6-month history of quidding and nasal discharge that contained feed material. Physical examination revealed weight loss and dorsal displacement of the soft palate, caused by a soft tissue mass located at the dorsal aspect of the base of the tongue. Surgical resection of the mass was successfully performed through an oral approach. The histopathologic diagnosis was rhabdomyosarcoma.
Focal gingival hyperplasia in a horse. A diagnosis of gingival hyperplasia in a 22-year-old Quarter Horse gelding was confirmed by histologic examination. Clinical signs included difficulty eating hay, and a large, intraoral soft tissue mass measuring 13 x 8 x 4.5 cm. The mass was located in the mucosa on the lingual aspect of the caudal left portion of the mandible, ventral to the base of the tongue, and covered the second and third lower molars, extending rostrally along the buccal mucosa to the premolars. The left maxillary second and third molars were overgrown with sharp edges. Lateral radiography of the mandible revealed abse...
Radiographic examination of the equine head. Radiographic examinations of the equine head can be performed with portable x-ray machines. The views comprising the examination depend on the area of the head being examined. With a knowledge of radiographic anatomy and radiographic signs of disease, valuable diagnostic information can be obtained from the radiographic examination. In addition, the radiographic information can also be used to develop a prognosis and determine the most appropriate therapy.
Reconstructive surgery of selected injuries of the head. Traumatic injuries to the head region of the horse are a common presenting complaint. Because of a copious blood supply, these wounds typically exhibit a tremendous capability for healing. By following the basic principles of wound management and employing a few techniques unique for specific injuries, the healing of these wounds can result in a satisfactory outcome.
[Spavin in horses–clinical, radiological and scintigraphic findings]. Both hock joints were examined clinically, radiologically and scintigraphically in 80 horses with special regard to bone spavin. The positive x-ray and bone scan results corresponded in most cases. It was evident that there was no correlation between degree of lameness and/or extent of radiological findings and increased radioactive uptake in the joint. Scintigraphic evaluation may demonstrate early changes at the onset of bone spavin as well as the frequent bilateral nature of the condition.
Diagnostic techniques for evaluation of the paranasal sinuses. Physical examination of the paranasal sinuses is often insufficient to confidently reach a conclusion concerning suspected pathology in these cavities. Often, other evaluation techniques are necessary. This article describes physical examination, rhinoscopy, sinus centesis, radiology, and sinus endoscopy of the equine paranasal sinuses. These techniques can be used to diagnosis and determine the cause of most sinus disorders.
Clinical anatomy of the equine head. This topical presentation emphasizes the structures most likely to be encountered in the diagnosis and treatment of diseases of the equine head. Most of the approaches are from superficial to deep. Anatomic variations associated with aging are described. The larynx and guttural pouches are not included in this article.
Hemorrhage into the guttural pouch (auditory tube diverticulum) associated with rupture of the longus capitis muscle in three horses. Three horses were determined to have hemorrhage into a guttural pouch unassociated with mycosis, empyema, neoplasia, or foreign body. The source of the hemorrhage appeared to be the rupture of the longus capitis muscle and its associated vascular supply.
Clinical examination of the equine head. Examination of the equine head should be a routine part of any complete physical examination. It can be performed rapidly and efficiently while providing important information about the health and function of several major body systems.
Dental surgery. Anatomy, physiology, and diseases of the teeth are presented. Signs of dental disease and techniques for oral and radiographic examination of the teeth are discussed. Surgical procedures described include extraction, repulsion, and endodontic therapy.
[Pain prevention and pain treatment in small and large domestic animals]. The aim of this article is to emphasize the need for analgesic medication in animals in possibly painful situations, especially in the postoperative period. The two large groups of compounds used as analgesics--the opiates and the nonsteroidal antiinflammatory drugs (NSAIDs)--are described with special reference to their pharmacokinetics, side-effects and toxicity, their mechanism of action, their indications and contraindications. Recommended doses of the different drugs available are given for the dog, the cat, the horse, the swine and the small and large ruminants.
Use of a modified Roux-en-Y procedure for treatment of pyloroduodenal obstruction in a horse. A modification of the Roux-en-Y anastomosis procedure was used to bypass a pyloroduodenal mass in a 12-year-old Arabian stallion. Clinical signs had consisted of a 4-week progression of ventral and hind limb edema, hypoproteinemia, fecal occult blood, intermittent abdominal pain, weight loss, and gastric reflux. On exploratory celiotomy, an obstructive mass was found in the pylorus and proximal portion of the duodenum. Gastrojejunostomy and duodenojejunostomy were performed by use of stapled side-to-side anastomosis techniques. Inaccessibility of the obstructed pyloric region prevented resecti...
Neurologic evaluation of the equine head and neurogenic dysphagia. Neurologic evaluation should be performed in horses with diseases of the head. Although neurologic examination should focus on assessing behavior, mental status, and cranial nerve evaluation, evaluation of neurologic function of other body regions should be performed. Neurologic evaluation of the head can be performed expediently by practitioners to provide useful diagnostic and prognostic information. The numerous causes of dysphagia can be classified as obstructive, painful, or neurogenic. Common causes of neurogenic dysphagia are summarized, and methods for initial diagnosis and management ...
Examination of the oral cavity and routine dental care. Techniques and equipment used to examine the oral cavity thoroughly are explained. Common routine dental procedures described include removal of enamel points, wolf teeth, and retained caps. Abnormalities of the incisors are discussed.
Miscellaneous conditions of the equine head. Nutritional secondary hyperparathyroidism is associated with horses that are fed diets with an imbalance of calcium and phosphorus or diets containing oxalates. Clinical signs include a shifting lameness, with tenderness of the joints, reluctance to move, or a stiff, stilted gait. Some horses may have broadening of the nasal bones, enlargement of the maxilla and/or the mandible, or a ridge over the nasal bones. Diagnosis may include physical examination findings; analysis of feed; and clinical pathologic data, which may include normocalcemia, normal to increased serum phosphorus, and increased...
Incarceration of the large colon in the gastrosplenic ligament of a horse. Incarceration of the large colon through a rent in the gastrosplenic ligament of a horse was surgically corrected via ventral midline celiotomy. Clinical signs were similar to those in other horses with nonstrangulating large colon disorders. Diagnosis of large colon incarceration in the gastrosplenic ligament was determined by surgical abdominal exploration. The findings of medial deviation of the spleen, location of the large colon lateral to the stomach and caudolateral to the spleen, and caudocraniad passage of the large colon through the gastrosplenic ligament are similar to findings in h...
