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.
Decreased tear production associated with general anesthesia in the horse. Schirmer I tear tests were conducted on 14 horses. The test was performed before and after IV administration of xylazine hydrochloride, during maintenance anesthesia with halothane in oxygen, and 3 hours after discontinuation of anesthesia. Xylazine hydrochloride did not decrease tear production from the mean base-line value of 23.94 +/- 5.23 mm/min after its IV administration. Tear production was decreased to mean values of 15.57 +/- 4.29 mm/min at 30 minutes and 13.84 +/- 4.25 mm/min at 60 minutes during the maintenance of halothane anesthesia. Three hours after anesthesia was discontinued, ...
[Topographico-anatomic data on the testicular artery, ductus deferens artery and cremaster artery in the stallion]. To study the vascularization of the testis of stallions we used 96 testes. We examined its topography and anatomy by roentgenography, stereoroentgenography, by the corosive method, and by means of gel and China ink injections. To make the roentgeno-arteriograms we used minimum emulsified in glycerine as contrast medium. The branching off of the Aa. testiculares from the Aorta abdominalis is variable in stallions. We observed also a peculiar age-dependent arrangement of the loops of the convolution. In the adult stallion, the shape of the convolution is either cylindrical or conical, spindle-sh...
Fractures of the distal phalanx in horses. Nineteen cases of fracture of the distal phalanx in horses are reviewed. This represented 1.1% of the total number of horses seen at Murdoch University Veterinary Hospital (MUVH) over a 32-month period. All horses were managed conservatively. Eight horses made a complete recovery. Three are being trained again and are not lame. Four horses made a limited recovery. Two horses are still resting and one horse was killed humanely when it still showed lameness after 2 years. One horse was killed humanely after the fracture was first diagnosed.
Segmental thoracolumbar spinal (subarachnoid) analgesia in conscious horses. A new technique for producing segmental subarachnoid analgesia in adult horses without causing complete loss of locomotor control is described. A 17-gauge Huber point (Tuohy) needle was used to place a catheter with a stylet into the subarachnoid space at the lumbosacral intervertebral space in 13 adult horses (weighing 500 +/- 60 kg, representing both sexes) and to advance the catheter craniad to the thoracolumbar area. The position of the catheter was confirmed radiographically. A 2% mepivacaine hydrochloride solution (1.5 ml, 30 mg) was injected through the catheter at a rate of 0.5 ml/60 s...
Joint mice in the fetlock joint–osteochondritis dissecans. Joint mice in the horse is a wellknown condition, but during the last years diagnosed with increasing frequency. Ethiology and prognosis thus become of major interest. 53 cases of mice in the fetlock are examined and divided in 3 groups on the basis of localization and appearance. On one group characterised by a localization in the plantar aspect of the joint and clearly separated from the tuberosites of the first phalanx histological investigations were carried out resulting in the statement that the mice can be the result of osteochondrosis. Surgical intervention in cases with clinical sympt...
Reaction of normal equine eyes to radio-frequency current-induced hyperthermia. In the main study, hyperthermia was induced by radio-frequency current to obtain a single, central, corneal lesion in the right eye and 2 separate limbal lesions in the left eye of 13 light horses and 8 ponies. Intracorneal and intralimbal temperature profiles for the procedure were obtained in a separate study from the eyes of a horse and a pony treated in the same manner. After treatment of the principal eyes and 6 sham-treated eyes, clinical observations were conducted for up to 6 months, using indirect ophthalmoscopy, biomicroscopy, and fluorescein staining. Immediately after hyperthermic ...
Electrocardiographic changes in induced hyperkalemia in ponies. In 11 crossbred ponies, hyperkalemia was induced by acute intracardiac infusion of a 0.4M solution of potassium chloride. The ECG changes noticed can be assigned to 4 stages: (1) a widening and a lowering of amplitude followed by inversion and final disappearance of the P wave; (2) an increase in the amplitude of the T wave; (3) an increase in the QRS interval, with some irregularity in the ventricular rate; and (4) periods of cardiac arrest that became terminal or were followed by ventricular fibrillation. At plasma potassium values of greater than 7.5 mM/L, the T-wave amplitude and duration ...
Effect of experimental uterine tube occlusion on plasma penicillin concentrations following intrauterine instillation in pony mares. PREVIOUS studies have shown that instillation of sodium benzylpenicillin into the uterine lumen of ponies in small volumes is followed by peak plasma concentrations of the antibiotic in 10to 15 mins (Allen 1978; Allen and Clarke 1978). However, the assumption that the circulating penicillin is absorbed only through the endometrium is questionable because Allen, Kessy and Noakes (1979) concluded that the intrauterine instillation of phenolsulphonphthalein was followed by absorption of the dye from the peritoneal cavity, after passage along the uterine tubes.
The present investigation was carri...
Clinical bronchography in the horse: development of a method using barium sulphate powder. A method for performing bronchography in standing nonanaesthetized horses was developed. Bronchography was performed by insufflating the previously intubated trachea with a mixture of 120 to 200 g of finely powdered barium sulphate mixed with 3 to 7 g of powdered methyl cellulose. The mixture was delivered from an ether vaporiser into which compressed air was blown. Premedication with atropine sulphate immediately before insufflation minimised bronchoconstriction. Satisfactory bronchograms with contrast visible down to the seventh and eighth bronchial divisions were obtained in 80 per cent of ...
A comparison of chemical and electrophoretic methods of serum protein determinations in clinically normal domestic animals of various ages. The biuret total protein method and a bromcresol green (BCG) albumin method were used on the Abbott ABA-100 chemistry analyzer to assay serum proteins in clinically normal cattle, sheep, ponies, pigs, and ducks. Total proteins were also read on a refractometer and mylar supported cellulose acetate electrophoresis was performed. Globulins and A/G ratios were calculated from the chemical method and the results compared with the electrophoretic method. Total protein, albumin and A/G ratios in the ponies, sheep and older cattle were in agreement between the two methods. The younger cattle and all ...
Periosteal transection for correction of angular limb deformities in foals. Seventeen foals with angular limb deformities of the distal end of the radius (valgus: 26 limbs), distal end of the tibia (valgus: 6 limbs), and distal end of the 3rd metacarpal bone/metatarsal bone (varus: 4 limbs) were treated surgically by means of hemicircumferential division of the periosteum proximal to the involved growth plate, at the concave side of the bone. There was some correction in all cases. The best results were seen in the radius, where 22 of 25 limbs were corrected to a deviation of 4 degrees or less. Satisfactory correction was obtained in the 6 tibias, the 2 third metacarp...
