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.
Effect of spasmolytic analgesic drugs on the motility patterns of the equine small intestine. The effect of acepromazine, Buscopan (Crown Chemicals), pethidine and methadone was evaluated in ponies prepared with Thiry-Vella (T-V) loops. Motility was assessed by electrophysiological means (bipolar electrodes and strain gauge transducers) and by the passage through the T-V loop of a fluid test meal. Results were obtained from 26 experiments in three ponies and compared with six control experiments, in which saline had been administered to the same ponies. Each pony acted as its own control in each experiment and pre and post treatment values for slow wave frequency, spiking activity, del...
Nonstrangulated colonic displacement in horses. Nonstrangulated colonic displacement was diagnosed by exploratory celiotomy in 32 horses with acute abdominal pain. Clinical signs progressed slowly and included evidence of mild to moderate abdominal pain, good cardiovascular status, reduced intestinal sounds, and normal peritoneal fluid, and resembled those of colonic impaction. In most horses, rectal palpation supported a diagnosis of colonic obstruction but not a diagnosis of colonic impaction.
Equine esophageal pressure profile. Esophageal motility was studied in 5 healthy adult horses, using a 4 side-hole catheter assembly continuously perfused with distilled water. Resting pressure and maximal pressures generated during swallowing were measured over the whole length of the esophagus (mean +/- S means = 132.7 +/- 2.31 cm). Four functionally distinct regions of the esophagus were demonstrated: cranial esophageal sphincter, caudal esophageal sphincter, and "fast" and "slow" regions in the body of the esophagus. The resting pressure of the cranial and caudal esophageal sphincters were 171.1 +/- 20.45 (x +/- S means) and...
Pre-race testing and its role in equine medication control. In general, blood is the only material on which a practical pre-race testing scheme can be based. Blood testing is not as sensitive as urine testing and detects only about 66 per cent of the drugs detectable in urine. Therefore, pre-race blood testing is always performed in conjunction with post race urine testing. Because blood is easily and rapidly drawn, the use of blood samples in all post race testing schemes is recommended. Pre-race testing is also a relatively expensive proposition, but it is the only method which actually prevents the running of an illegally medicated horse.
The diagnosis and treatment of arthritis in horses. In this paper on the diagnosis and treatment of arthritis in horses, both degenerative arthritis and septic arthritis are considered. Diagnosis should be made on the combination of clinical examination together with the use of diagnostic aids such as radiology, intra-articular local anaesthesia and synovial fluid analysis. Intra-articular therapy appears to be the most effective in the treatment of degenerative arthritis. Excellent responses to therapy have been reported with corticosteroids, sodium hyaluronate, orgotein and synovial fluid transfer, where joints showed an absence of degenerati...
Multiple congenital heart anomalies in five Arabian foals. Five Arabian or half-Arabian foals with suspected multiple cardiac anomalies were examined. Various combinations of clinical examination, electrocardiography, angiocardiography, cardiac catheterization, blood gas analysis, radiography, and echocardiography resulted in clinical data that allowed accurate antemortem diagnoses to be made. In 4 cases, the clinical diagnosis was substantiated by postmortem findings. The confirmed diagnoses were: pseudotruncus arteriosus, a combination of patent ductus arteriosus, pulmonic stenosis, and tricuspid stenosis, pentalogy of Fallot, and tricuspid atresia....
Prognostic value of endometrial biopsy in the mare: a retrospective analysis. A retrospective analysis was made of 79 endometrial biopsy specimens obtained from mares with histories of infertility. The specimens were classified into 3 standard prognostic categories, according to the severity of the histologic changes. The 36 mares that had few endometrial lesions (category I) had a foaling rate of 78%. The 29 mares that had more severe endometrial changes (category II) had a foaling rate of 55%. The 14 mares with the most severe endometrial lesions (category III) had a foaling rate of 35%. The pregnancy losses for each category were 9.7%, 23.8%, and 44.4%, respectively....
Mononuclear phagocytes of peritoneal fluid. Cells in the peritoneal fluid from 179 horses were examined in Giemsa stained preparations using light microscopy. Mononuclear phagocytes were a common cell type observed in normal fluids. In the absence of stimulation they were morphologically similar to the peripheral blood monocyte and the unstimulated mesothelial cell. In acute inflammatory effusions their proportion decreased significantly but, as the condition resolved, monocytes began to migrate into the cavity gradually becoming more numerous, transforming into larger macrophages and assuming an increasing phagocytic role. They were of...
Pulmonary haemorrhage in standardbred horses after racing. Endoscopic examinations of the upper respiratory tract were done on 92 of 314 Standardbred horses that raced one or more times at 4 consecutive, weekly race meetings. Although participation was voluntary, the characteristics of the population of horses examined were not statistically different from those of all horses that raced. No horse showed epistaxis, but 34 (32.4%) examinations of the trachea revealed blood that ranged from a trace in the tracheal mucus to large amounts scattered over the tracheal walls. Forty-four horses exhibited minor degrees of pharyngeal lymphoid hyperplasia, 2 had ...
Cholelithiasis in four horses. Four cases of cholelithiasis in horses were reviewed. Two horses were examined because of recurrent abdominal pain. Clinical laboratory data, results of physical examination, and history indicated biliary obstruction. In 1 case, B-mode ultrasonography aided in the diagnosis, which was confirmed at necropsy. In 2 horses, the biliary calculi were incidental necropsy findings.
The anion gap as a prognostic indicator in horses with abdominal pain. The anion gap was calculated for each of 90 horses with signs of abdominal pain, using laboratory data obtained shortly after admission. The anion gap was defined as the difference between the sodium concentration (mEq/L) and the sum of the chloride and bicarbonate concentrations. To evaluate the use of the anion gap as a prognostic indicator, the survival rates were calculated for horses whose anion gap concentrations were within various ranges. It was found that the probability of survival decreased as the anion gap progressively increased about 20 mEq/L. The survival rates for increasing ra...
