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.
O'Brien TR, Hornof WJ, Meagher DM.Subchondral lesions were identified in the distal palmar region of the third metacarpus in 21 fetlock joints of 15 Thoroughbred horses. The lesions were more commonly identified on the lateromedial and flexed lateral projection, with the flexed lateral projection permitting optimal visualization of the lesion. Lesions appeared as poorly marginated, radiolucent defects and were located at the level of the base of the proximal sesamoid bones. The shape and distribution of the radiolucent defects were: crescent, 4; flattened, 4; shallow concavity, 5; deep concavity, 3; oval, 3; and circular, 2. S...
McIlwraith CW, Van Sickle DC.Arthritis was experimentally induced in the intercarpal joints of a series of mature ponies by the intraarticular injections of 400 microgram of the polyene antibiotic filipin in 1 ml of dimethyl sulfoxide. Twelve consecutive weekly injections were administered and the ponies were euthanatized 4 weeks after the last injection of filipin was made. The ponies were exercised for 1 hour each day throughout the experiment. Articular cartilage specimens from 4 sites in each intercarpal joint were examined histologically and histo-chemically. For the histochemical examination, safranin O-fast green, ...
Gulick BA, Meagher DM.A commercially available polyvinyl chloride intravenous catheter was studied in 9 horses for 3 to 10 days to evaluate the catheter's suitability for use in the horse, to develop a new insertion technique, and to establish a protocol for catheter care. Seven of the animals were clinically normal horses receiving parenteral nutrition; one was a horse with hypocalcemia receiving frequent intravenous injections of calcium gluconate, and one was a clinically normal horse receiving no infusions. The catheter dressings were changed every 48 hours, and an aspirate from the catheter and the catheter ti...
Ekman L, Nilsson G, Persson L, Lumsden JH.A method of determining the volumes of synovia in certain articular cavities in the horse is described. The method is based on the degree of dilution of human serum albumin labelled with I that is injected into the joint. It is shown that uniform distribution of the injected substance is attained within 20 min post injection. The elimination of the labelled substance was found to follow the pattern of a single exponential function. The following volumes of synovia were determined (mean ± s) : hock, 39.8 ± 2.1 ml; radio-carpal, 12.6 ±1.5 ml; intercarpal, 14.9 ± 0.6 ml; foreleg fetlock joint...
Feng KR.A method of electro-acupuncture for treatment of intestinal impaction of the horse was reported. The unique technique of the treatment includes deep needle insertion and the "triple tetanic treatment." Possible mechanism of this form of treatment was discussed.
Pecheur M.A number of good anthelmintic drugs are currently available which eliminate gastrointestinal nematodes of equids with over 90% success. This is shown by comparing results of critical tests conducted with 9 anthelmintic agents on ponies using the following dosages: 19 mg/kg for Pyrantel embonate, 10 mg/kg for Oxfendazole, 10 mg/kg for Mebendazole, 5 mg/kg for Albendazole, 40 mg/kg for Dichlorvos, 44 mg/kg for Thiabendazole, 7.5 mg/kg, for Fenbendazole, 20 mg/kg for Cambendazole and 7 mg/kg for Parbendazole. From 6 to 9 ponies were treated with each of these anthelmintic agents. Based on total a...
Webbon PM.The radiography of horses on behalf of a purchaser has become an inevitable part of a veterinarian's work. Radiography should, in theory, pose no more problems than a general clinical examination. In practice, difficulties arise when insufficient or inadequate films are taken or the films are misinterpreted. Radiographs of a diagnostic quality need to be taken and interpreted by a veterinarian who is reasonably well versed in radiological interpretation. Occasionally a lesion will be overlooked or misinterpreted and the radiographs will be retained so that the veterinarian's judgement can be c...
Grodzki K.The receptor theory of the action of catecholamines as well as the synthesis and production of beta-adrenolytics gave new perspectives for the treatment of circulatory diseases and enabled to use the beta-adrenergic blockade in electrocardiographic diagnosis. The aim of this work was to study whether it is possible to modify the oral method of administration used in human beings, into intravenous one, and what an information could be obtained as to actual heart condition after practolol injection. The results can be summarized as follows:--Practolol-Polfa injected intravenously in amounts of 3...
Irwin DH, Howell DW.The clinical and laboratory findings of illness in a 2-year-old Thoroughbred filly are described. The treatment employed, including unilateral nephrectomy, and the macro- and microscopic findings in the diseases kidney are presented and this rare case is discussed briefly.
Tschudi P.The physiological and technical basis of the electrocardiography are shortly explained. The electrodes used for the recording of bipolare thoracal leads, their fixation on the horse, the practical procedure of a ECG-recording, its appearance and variation are described and illustrated. A recommendation for a systematic evaluation and interpretation is being proposed.
Diehl M, Gerber H, Schifferli D, Nicolet J.A systemic investigation of wound infection in the horse after operative treatment of large wounds reveals that the age of the wound is of critical importance. The limit for an uncomplicated healing process lies around four hours. The duration of the operation itself is of little significance, the location of the lesion on the body of the horse, however, plays a major role. The pattern of isolated bacterial organisms is discussed in relation to the duration of hospital treatment. It is concluded that a systemic antibiotic therapy is of no value and that a local antibiotic therapy is only indic...
Narinx F, Monclin S, Sauvage A, Vercruysse E, Heimann M, Alloway E, Vandersmissen M, Grauwels M.To describe the clinical presentation and treatment of an ectopic periorbital lymph node in two young horses. Two warm-blood horses were presented at the equine clinic of the University of Liège with a periorbital non-painful mass. Differential diagnosis included neoplasm (lymphoma), (sterile) abscess, cyst, ectopic lacrimal gland tissue, hematoma, adipose tissue, or ectopic lymphoid tissue. Information collected included physical and ophthalmic examination findings, results of the ocular and periocular ultrasound, surgical procedure, histopathology, and follow-up. Masses of 2 × 2 cm and 3 Ã...
Watt BC, Beck BE.Diagnosis and removal of a nasal polyp in a horse using standing chemical restraint and readily available equipment are described. Histopathology of the polyp and differential diagnoses are discussed.
Blue MG.Minor accidents during natural mating are common occurrences during the breeding of horses. Mares may suffer from a variety of genital injuries including vulval separations, vaginal lacerations and, less commonly, vaginal rupture. Possible sequelae to, and management of, these injuries are described, with additional mention of false entry by the stallion and persistent hymen in maiden mares. Vaginal rupture during natural mating can lead to death of the mare. The implications for litigation involving veterinary surgeons and horse breeders are discussed.
Podadera JM, Bell RJ, Dart AJ.Two horses presented with a history of severe lameness that was localised to the area around the second phalanx (P2) of one forelimb. Radiographs of the second phalanx of both horses were unremarkable, apart from some smooth periosteal new bone production on the dorsum of P2. Magnetic resonance imaging revealed a non-displaced fracture of P2 in both horses. One horse was euthanased because of a poor prognosis for racing, but the second horse was treated conservatively and salvaged for breeding. Magnetic resonance imaging is a newer imaging modality in horses and may be useful in diagnosing cas...
Reed SM.The veterinarian needs to be able to incorporate an accurate neurologic examination as a portion of the pre-purchase evaluation. Subtle neurologic deficits may be hidden by musculoskeletal disease or missed as a result of lack of knowledge or understanding of these disorders. It is important to known which musculoskeletal disorders are commonly associated with neurologic disease to better assist the buyer with the decision about whether to purchase the animal.
Raggio I, Lefebvre RC, Poitras P, Vaillancourt D, Goff AK.Multiple pregnancies are still an important cause of noninfectious abortion, stillbirth, neonatal mortality, and significant delays in reproductive performance in mares. Despite new management techniques, reduction in multiple pregnancies is an ongoing preoccupation and challenge for the equine veterinarian. The aim of the present study was to establish a twin pregnancy experimental model in the mare to study the effectiveness of a transvaginal ultrasound-guided embryonic vesicle injection. Mares in heat were inseminated and then received an embryo at day 7 of the estrous cycle. At days 14 and...
