Topic:Clinical Symptoms
Clinical symptoms in horses encompass a range of observable signs that may indicate underlying health issues, such as disease, injury, or physiological stress. These symptoms can vary widely depending on the condition and may include changes in behavior, appetite, respiratory patterns, or physical appearance. Common clinical symptoms in horses include lameness, colic, coughing, nasal discharge, and changes in body temperature or heart rate. Identifying and interpreting these symptoms is an essential aspect of equine veterinary practice, as they provide critical information for diagnosis and management of health conditions. This page compiles peer-reviewed research studies and scholarly articles that explore the identification, assessment, and implications of clinical symptoms in equine health management.
Rupture of the diaphragm in the horse. Four cases of fatal diaphragmatic rupture in the horse are described. In 2 cases there was no history of injury but the other 2 animals had sustained recent thoracic trauma. Three of the horses had signs of colic and bowel obstruction complicated, in 2 cases, by respiratory embarrassment; the fourth died rapidly, presumably of shock. Previously published cases are reviewed and the causes, clinical effects, diagnosis and treatment of the disorder are discussed.
Liver fluke infection in horses and ponies. Thirty eight cases of Fasciola hepatica infection in horses with associated clinical signs are reported. A method of examining large amounts of faeces for fluke is described. A safe method of treatment for infected horses is given which involves oral medication with oxyclozanide at a dose rate of 15 ml/50 kg body weight.
A clotting defect in an Arab colt foal. A multiple clotting defect in a 3 month old Arab colt foal associated with a deficiency in Factors VIII, IX, and XI is described. No abnormalities in clotting factors were detected in the colt's sire, dam, half-sister and half-brother.
A review of the diagnosis and treatment of fluid and electrolyte disorders in the horse. Disturbances of fluid and electrolyte balance may occur in the horse as a consequence of many disease processes. Disorders may be classified into 3 main categories, primary water loss, mixed water and electrolyte depletion and acid base disturbances. This paper reviews the changes which occur with each type of disorder and discusses methods of diagnosis and assessment of such imbalances. The principles of treatment are described and the management of fluid replacement therapy in 3 of the disorders, mainly acute intestinal obstruction, inability to drink and diarrohea is discussed.
Non-surgical correction of a uterine torsion in the mare. A case of uterine torsion is described and its correction under general anaesthesia by a method described by Schaffer for the cow. The degree of torsion was 180 degrees and in a clockwise direction. After correction the foal was found to be alive and in anterior presentation and ventral position; it was born normally 84 days later.
Evaluation of monensin toxicity in the horse. Gelded horses of mixed breeding, ranging in weight between 360 and 455 kg, were fed pellets that contained monensin at concentrations of 279, 124, 31, and 0 ppm. Of 2 horses fed 279 ppm (253 g/T), both died. Of 3 horses fed 125 ppm (113 g/T), 1 died; feed intake was reduced in the 2 survivors. Of 3 horses fed 31 ppm (28 g/T), 1 had a transitory reduction in feed intake and the other 2 remained clinically normal. The 2 horses fed 0 ppm remained clinically normal. Monensin was also given to horses by gavage, at dosages of 1, 2, 3, 4, or 20 mg/kg of body weight. The LD50 was estimated to be betwe...
Effects of Saffan administered intravenously in the horse. Saffan was injected intravenously on 41 occasions in 11 horses and ponies to investigate its possible use in clinical equine anaesthesia. The optimum dose for induction was 1-90 mg per kg. This dose was divided into two halves, the first half given in five seconds and the second half, containing suxamethonium chloride 0.1 mg per kg, in the next 10 seconds. Induction was associated with excitement for up to 30 secs after the assumption of recumbency. At this dose rate anaesthesia lasted five to eight minutes. Muscle relaxation was poor. Recovery was associated with marked tactile and audible hy...
Successful repair of a diaphragmatic hernia in a foal. The diagnosis and successful surgical treatment of a diaphragmatic hernia in a 12 weeks old standardbred foal are described. The clinical syndrome in horses generally is contrasted with that seen in the foal described in this paper. Some of the factors contributing to the clinical signs are discussed.
