Topic:Clinical Examination
Clinical examination in horses involves a systematic evaluation of the animal to assess its health status and identify any potential medical issues. This process typically includes a thorough physical assessment, which may cover observation of behavior and posture, palpation of body structures, auscultation of heart and lung sounds, and examination of the skin, eyes, and mucous membranes. Additional diagnostic tools such as thermography, endoscopy, or imaging techniques may be utilized to gather more detailed information. Clinical examination serves as a foundational step in veterinary diagnostics, aiding in the detection and management of diseases or injuries in horses. This page compiles peer-reviewed research studies and scholarly articles that explore methodologies, advancements, and findings related to clinical examination practices in equine medicine.
Computer processing of transaortic valve blood pressures in the horse using the first derivative of the left ventricular pressure trace. A method is described of processing transaortic valve pressures in the horse using the first derivative of the left ventricular pressure to define the beginning and end of each systolic complex. To determine the beginning of each systole three definitions of left ventricular end diastolic pressure (LVEDP), based on a 100, 150 or 200 mmHg/sec rate of left ventricular diastolic pressure rise, were evaluated. These definitions were also evaluated for their ability to determine isovolumic contraction time (ICT) and pulse interval. The best of these, LVEDP 150, was defined as the last point in dias...
Impedance monitoring of equine intestinal motility. Myoelectrical and myomechanical activities of the distal portion of the jejunum and pelvic flexure were studied in 7 ponies, using permanently implanted monopolar and bipolar stainless steel electrodes. Dental acrylic embedded recording electrodes were surgically sutured to the serosal surface of the distal portion of the jejunum and pelvic flexure. Myoelectrically, regular spike bursts and irregular spike bursts were observed in the jejunum. Short spike bursts and long spike bursts were recorded and associated with spike potentials, using impedance recording techniques. Electrical and mechani...
The toxicity of Datura stramonium (thorn apple) to horses. Meal contaminated by Datura stramonium seeds at the rate of 0.5% by weight was fed to two horses. Both horses showed clinical signs of depression, anorexia, weight loss, rapid heart and respiration rates, mydriasis, polyuria, polydipsia and diarrhoea. Both recovered with treatment. Maize screenings contaminated by the seeds had been used in the manufacture of the meal.
Electrical stimulation on skin wound healing in the horse: preliminary studies. The effect of low-level direct-current stimulation on skin wound healing in the horse was assessed. Self-sustaining electrical circuits with electrodes were implanted subcutaneously in or near the wound. Stimulation by direct current (10 or 20 microA) was used to determine the effect on equine skin healing. The efficacy of electrotherapy was evaluated by sequentially comparing the clinical appearance of the wound and measuring the size of the granulating wound bed. The histologic appearance of the healing stimulated wounds was compared with that in nonstimulated control wounds created on 9 hor...
Ultrasonic anatomy and pathology of the equine uterus. The morphological and pathological status of the uterus in mares was evaluated using a linear-array ultrasound scanner, and the ultrasonic properties of the uterus were characterized. The uterus was examined each day in 16 mares, beginning at mid-diestrus. The uterus was recorded as having an ultrasonic morphology characteristic of diestrus (endometrial folds not distinguishable), estrus (prominent endometrial folds) or an intermediate stage (folds only moderately distinguishable). The number of mares with an intermediate or estrous image increased gradually between day -7 (2 14 mares; ovulati...
[Surgical treatment of rectal prolapse in a 1-year-old mare resecting only the mucous membrane]. A mare with rectal prolaps was operated at Vienna University. The prolaps was corrected by mucosal resection only. The remaining vital layers of the corresponding intestinal section were saved. The advantage of a special tissue saving operating technique in the rectal area is seen in avoiding postoperative complications.
Effects of environmental control on pulmonary function of horses affected with chronic obstructive pulmonary disease. The effects of environmental control on horses affected with chronic obstructive pulmonary disease was assessed by clinical examination and pulmonary function tests, ie, maximum change in intrathoracic pressure, tidal volume, minute volume, non-elastic work of breathing, dynamic compliance, inspiratory and expiratory flow rates and arterial blood gas analysis. A controlled environment (ie, bedding horses on shredded paper and feeding a complete cubed diet) caused symptomatic COPD affected horses to become asymptomatic within four to 24 days (mean +/- sd 8.4 +/- 4.8 days). When asymptomatic, th...
Management of umbilical hernias in cattle and horses. The medical records of 60 cattle and 47 horses treated for umbilical hernia at the Western College of Veterinary Medicine over a 3-year period were studied retrospectively. Age, hernia size, physical signs at admission, reducibility, method of repair, prevalence, and types of complications were evaluated. Most patients were less than 6 months old, with hernias less than 10 cm long. Affected cattle had a higher prevalence of organic diseases associated with umbilical hernias and more postsurgical complications than did affected horses.
Chronic obstructive pulmonary disease in the horse. 1: Nature of the disease. The aetiology, pathophysiological changes, pathology and clinical signs of the disease as presently understood are discussed. The condition appears to be a hypersensitivity of the respiratory system in some horses to poor quality hay and straw. Micropolyspora faeni is the chief agent identified in the northern part of the United Kingdom. In other locations, the chief agent is probably different. The principal changes are spasm of the airways and bronchiolitis of the small airways. Onset may be acute or insidious. The chief clinical signs are well known but the disease process is reversible if ...
Identification of carriers of Streptococcus equi in a naturally infected herd. During an outbreak of strangles in a population of research horses, 4 mares were identified as carriers of Streptococcus equi. Three of the mares had typical signs of strangles (severe regional lymphadenitis with or without rupture of abscessed lymph nodes). The 4th mare experienced episodes of serous to mucopurulent nasal discharge, but never had more than a mild degree of lymph node enlargement. Streptococcus equi was isolated from the abscessed lymph nodes and from nasopharyngeal swab specimens from the first 3 mares from 6 to 19 weeks after rupture of involved nodes. Streptococcus equi was...
Assessment of the necessity for surgical intervention in cases of equine colic: a retrospective study. The present study retrospectively examined clinical and clinicopathological findings in horses with colic to determine which variables distinguished between medically treatable cases and cases which required surgical intervention. Heart rate, haematocrit, haemoglobin concentration, blood erythrocyte count, frequency of borborygmi and degree of mental depression showed the greatest differences (P less than 0.001) between medical and surgical groups. However, some variables which primarily evaluated cardiovascular function, ie, blood pressure, oral mucosal capillary refill time and blood lactate...
