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.
[Legal aspects of veterinary examinations of horses at purchase with regard to the new high court decision and prevailing dogma]. The existing statutory provisions in connection with the seller's liability for defects of a horse are nowadays unsatisfactory. This has led to an increasing number of cases in which veterinarians have been held liable for the purchaser's damages resulting from an incorrect or incomplete veterinary examination at point of sale. Courts have recently imposed extensive duties of care on the veterinary. He has not only to detect and disclose every minute defect of the horse, but has to give a prognosis of the development of the horse's healthiness and its future capability to meet the purchaser's ...
Use of an ELISA in the differential diagnosis of cauda equina neuritis and other equine neuropathies. In 27 potential neuropathies an enzyme-linked immunosorbent assay, using P2 preparations from either bovine or equine myelin, detected all cases of cauda equina neuritis in which there was caudal involvement. The test was of limited value in differentiating neuropathies involving only cranial or other peripheral nerves.
Ultrasonography of accessory sex glands in the stallion. The accessory sex glands of 10 stallions were examined by transrectal ultrasonography. Seminal vesicles were 26.4 +/- 5.2 (s.d.) mm in width and 9.2 +/- 3.1 mm in height. Ampullae were 16.3 +/- 3.6 mm in width and 12.9 +/- 3.9 mm in height. Bulbourethral glands were 19.7 +/- 4.6 mm in width and 32.4 +/- 6.7 mm in length. Prostate lobes exceeded 34 mm in width and were 23.5 +/- 5.7 mm in height. The prostatic isthmus was 6.0 +/- 1.4 mm in height. The seminal colliculus, masculine uterus, and deferent ducts were also identified and characterized. Five of these stallions were killed to compare tr...
[Diagnosis of liver diseases in dogs, cats and horses]. Clinical symptoms of hepatopathies are not specific and must be verified by further investigation. Laboratory diagnosis is a very useful method to decide if liver disease is present or not. In individual cases laboratory methods can give hints as to the aetiology of the illness. If necessary, biopsy, angiography or/and cholecystography can be carried out for further clarification of the diagnosis.
A modified parainguinal approach for cryptorchidectomy in horses. An evaluation in 107 horses. A modified parainguinal approach was used to castrate 119 abdominal cryptorchid horses. The operative time ranged from 10 to 30 minutes. Follow-up information was obtained for 107 horses. Swelling, more severe than that expected in routine castrations, was reported in six horses. An incisional abscess had to be drained in one horse and one horse died of unexplained causes 3 days after the surgery.
Diagnostic and surgical arthroscopy of the equine shoulder joint. An arthroscopic technique for examination and surgical treatment of conditions of the shoulder joint was evaluated in eight normal horses and two horses with osteochondrosis lesions. A single arthroscope entry point caudal to the infraspinatus tendon allowed inspection of the cranial, lateral, and caudal surfaces of the shoulder joint. With the humeral head and glenoid cavity distracted by a curved forceps, the entire cartilage surface of the shoulder could be examined. The caudomedial portion of the humeral head was seen better with a 70 degree angled arthroscope. Instruments for intra-articu...
[Establishment of a re-entrant ileo-cecal fistula in Equidae]. A re-entrant cannulation of the digestive tract was performed in Equidae (ponies and donkeys) between the distal extremity of the ileum and the base of the caecum. The operative technique was conceived to avoid risks of infection of the peritoneal cavity: the openings of the ileum and of the caecum were achieved only after the closure of the abdominal wall incision. Two donkeys were still alive ten months after the operation. This method can provide a convenient model for digestibility studies in Equidae, particularly for assessment of the pre-caecal digestibility.
[Hoof correction in foals]. The conformation of a foal's limbs is of interest beginning in the first days of life. The hoof also must not be neglected. Management and hoof care necessary for normal hoof development are discussed. In addition, pathological hoof shapes and their appropriate treatments are outlined.
[The morphology and innervation of the levator muscles of the ribs in the dog, cat, horse, and pig]. In the anatomical literature there are inconsistencies in the description of the levatores costarum muscles in man and in the domestic animals, and their innervation either by the dorsal or the ventral branches of the thoracic nerves. Therefore we studied the form, structure and, with the aid of the dissecting microscope, the innervation of these muscles in 7 dogs, 8 cats, 5 horses and 12 pigs. In the dog, cat and horse, mm. levatores costarum are present from the second to the last rib. In the pig, these muscles are present from the second to the 15th rib, even in individuals with 16 pairs of...
Heparin-induced agglutination of erythrocytes in horses. Heparin was administered subcutaneously 2 times a day for 4 days to 5 horses. An additional group of 5 horses was used as time-matched controls. Significant decreases in PCV, erythrocyte count, and hemoglobin concentration were observed during heparin therapy. The mean corpuscular volume (MCV) of the heparin-treated horses increased to a peak value of 66.1 fl on the last day of treatment. Erythrocyte creatine concentration and glucose 6-phosphate dehydrogenase activity increased moderately during the treatment. These data indicated that the rapid, profound increase in MCV during heparin therap...
Subclinical entrapment neuropathy of the equine suprascapular nerve. The suprascapular nerve from 14 horses, which had no clinical evidence of spinatus muscle atrophy, were obtained to determine whether the nerve was sub-clinically compressed at the scapular edge. The nerves were divided into three portions, proximal and distal to the scapular edge and as it reflected around it. In nine horses there was evidence of a chronic neuropathy which varied in severity and which was most severe at the site of reflection, where the nerve appeared constricted by a tendinous band. At this site the predominant change was that of chronic demyelination and remyelination, with...
The pathogenesis of dystocia and fetal malformation in the horse. From a total of 601 severe dystocias in mares, 408 (68%) of the fetuses were in anterior, 95 (16%) in posterior and 98 (16%) in transverse presentation, compared with 99%, 1% and 0.1% respectively for spontaneous parturitions. From the cases with anterior presentation, 151 (37%) showed reflected heads and necks. From the cases with posterior presentation, 47 (50%) presented hip flexions, 25% had hock flexions, and 25% had stretched hind legs, 45 (47%) of the fetuses were in lateral or ventral position, and 28 (30%) of the fetuses were malformed (mainly torticollis and head scoliosis). All 98 c...
Experimental large colon resection at the cecocolic ligament in the horse. Ten normal horses had approximately 95% of the length of the large colon resected with a side-to-side anastomosis between right ventral and right dorsal colon performed with surgical stapling equipment. Four horses died shortly after surgery of colitis (1 horse) or failure of the TA 90 transection staple line (3 horses). Another horse died 4 months after surgery from disseminated streptococcal infection but had recovered well from the colon resection. Five horses survived long term (18 months) with no clinical evidence of adverse effects of the resection. Surviving horses had weight loss and s...
Extensive large colon resection in the pony. II. Digestibility studies and postmortem findings. The nutritional implications and adaptive processes resulting from resection of 75% of the length of the large colon in ponies were investigated. Ten ponies in good physical condition were divided into two groups: six in the experimental group and four in the control group. During the sixth postoperative month, two digestibility studies were conducted, and phosphate fractional renal excretion and serum biochemical profiles were determined in both groups. The ponies (N = 10) were euthanized six months postoperatively, and gross and histopathological examinations were performed. Results of the s...
The optics of comparative ophthalmoscopy. One factor peculiar to the practice of comparative ophthalmoscopy is the very large variation in ocular size of the animals examined, a factor which is ignored in current textbook treatments of the subject. We have computed values of lateral magnification, axial magnification, angular field of view and linear field of view for 19 species of terrestrial vertebrates. The dimensional value of a 1 diopter change in direct ophthalmoscopic focus was also determined. The anterior focal length of the eye in air and the vitreal refractive index were the intrinsic optical parameters of the animal's eye ...
Surgical management of chronic laminitis in horses: 13 cases (1983-1985). Thirteen horses with chronic refractory laminitis were evaluated and treated. In each horse, deep digital flexor tenotomy was performed on all affected limbs at the level of the midpastern. Five horses returned to limited athletic endeavors, 6 horses improved and were comfortable on pasture, 1 horse improved clinically, but was euthanatized for economic reasons, and 1 horse improved, but deteriorated 9 months after surgery and was euthanatized. Results of this study indicated that deep digital flexor tenotomy at the level of the midpastern can be used effectively as a salvage procedure in hors...
[Avulsion fracture of the tendon of origin of the long extensor muscle of the toe in a horse and a cat]. An avulsion fracture of the tendon of origin of the extensor digitorum longus muscle is reported in a horse and a cat. This avulsion fracture was due to injury in both animals. There was a striking similarity of radiographic findings in these animals, with involvement of the lateral trochlear ridge and lateral condyle of the femur. The horse was slaughtered because of a poor prognosis as a riding-horse. Fixation of the avulsed fragment with two Kirschner wires resulted in complete recovery in the cat.
Techniques for taking a behavioral history. A thorough behavioral history is essential for adequate assessment of a given case. In reviewing the chief complaint, a description of what actually happened, rather than the owner's interpretation of what happened, is required. Other behavior problems, environment, rearing history, and training need to be reviewed. Sample question sets for some common problems are given.
Restraint. The object of restraint is to limit, restrict, and keep under control the animal's movement while performing different procedures. The author discusses the importance of evaluating the horse and its owner prior to employing any type of restraint, various concepts of restraint, and examples of situations in which restraint may be required.
[The clinical pharmacology of glycerol guaiacolate ether in the horse–a review]. The physical and chemical properties, administration, biotransformation, pharmacological effects, clinical applications, side-effects, toxicity and contraindications of glyceryl guaiacolate ether in the horse are reviewed.
Laryngotracheal injury associated with nasotracheal intubation in the horse. Laryngotracheal damage following short-term nasotracheal intubation was studied in 7 healthy horses. A flexible fiberoptic endoscope was used to examine the upper respiratory tract of each horse before nasal intubation with a cuffed silicone endotracheal tube and again at 1 hour, 24 hours, and 48 hours after extubation. Any abnormalities still evident at 48 hours were evaluated at 7 days after extubation. Mucosal damage involved the nasal meatus (5 of 7 horses), the arytenoid cartilages (5 of 7 horses), the trachea (5 of 7 horses), the dorsal pharyngeal recess (4 of 7 horses), the vocal folds ...
Arthroscopic landmarks of the equine carpus. The radiocarpal and middle carpal joints of 4 clinically normal horses and 24 necropsy specimens were examined with an arthroscope to describe the topographic anatomy of these joints. The carpal bones of the radiocarpal joint had congruent articular surfaces in extension, but carpal flexion resulted in a stairstep between the radial and intermediate carpal bones. The variable surface anatomy, as well as the restricted synovial space and the technical limitations of the arthroscope, contributed to the need for more than one arthroscopic approach to the radiocarpal joint to ensure a thorough exa...
Navicular suspensory desmotomy in the treatment of navicular disease: technique and preliminary results. The technique of navicular suspensory desmotomy for the treatment of navicular disease is described and the rationale behind its development is discussed. To date 16 horses involved in a clinical evaluation of the technique have been assessed six months after surgery. Thirteen of these horses are able to work without lameness.
Study of arterial blood pressure in newborn foals using an electronic sphygmomanometer. An electronic sphygmomanometer which functions on oscillometric principles, was used to measure arterial blood pressure in foals. Its accuracy was assessed by comparison with results obtained by direct measurement in anaesthetised pony foals, aged 34 to 64 days. Correlations between data obtained by the two methods were highly significant but the sphygmomanometric readings were consistently lower than those obtained by direct measurement. An equation was derived from the pooled values for mean, systolic and diastolic pressure measurements. This was used as a correction factor when the oscillom...
Studies on the optimal temperature of flotation tanks in the management of skeletal injuries in the horse. In order to determine optimum tank temperature, nine horses were allocated randomly to three groups and placed in a flotation tank at temperatures of 28 degrees C, 32 degrees C and 36 degrees C. Their progress was monitored by subjective and objective clinical measurements and a variety of laboratory parameters. A 'reacclimatisation crisis' following removal from the tank was observed in most horses after immersion for 21 days and it was concluded that a tank temperature of 36 degrees C provided maximum patient comfort and minimum homoeostatic disturbance.
