Endoscopy of the upper respiratory tract during treadmill exercise: a clinical study of 100 horses   总被引：1，自引：0，他引：1

SUMMARY: Endoscopy of the upper respiratory tract was performed in 100 horses during high speed treadmill exercise. Reasons for endoscopy were a history of an abnormal noise during exercise in 75 horses, poor performance in 17 horses and to evaluate the results of upper respiratory tract surgery in 8 horses. Of the 75 horses with a history of an abnormal noise during exercise the cause was determined in 67 (89%). Endoscopic abnormalities were detected at rest in 40 of these 75 horses (53%). In these 40 horses, a similar diagnosis as to the cause of the abnormal noise was made at rest and during exercise on the treadmill in 19 cases, while in the remaining 21 the endoscopic findings during exercise varied from that seen at rest. This included 3 horses in which a diagnosis was made at rest but no abnormalities were detected during exercise. Some of the findings during treadmill endoscopy included laryngeal dysfunction, grades 3, 4 and 5 (22 cases), dorsal displacement of the soft palate (20), epiglottic entrapment (8), epiglottic flutter (4), aryepiglottic fold flutter (4), pharyngeal collapse (3), arytenoiditis (3), vocal cord flutter (3), false nostril noise (2), pharyngeal lymphoid hyperplasia (2), soft palate haemorrhage (1) and positional arytenoid collapse (1). More than one abnormality was observed during exercise in 7 horses. A complete and correct diagnosis based on the resting endoscopy findings alone was made in 19 (25%) of these 75 cases. In the 17 horses examined because of poor performance, no abnormalities were detected during treadmill endoscopy that were not evident at rest. None of these 17 horses presented with a history of an abnormal respiratory noise, although one, diagnosed as having grade 4 laryngeal function at rest and exercise, did make a characteristic inspiratory noise during treadmill exercise. Eight horses were evaluated after surgery for correction of laryngeal hemiplegia, as the post-operative performance or the amount of respiratory noise present was considered unsatisfactory. Of these, 3 were found to have a satisfactory airway during exercise and other reasons for poor performance were detected; 3 had insufficient abduction; and 2 had intermittent dorsal displacement of the soft palate. Endoscopy of the upper respiratory tract was found to be a useful technique for evaluating the cause of abnormal respiratory noise in most cases. We concluded that treadmill endoscopy in horses presented for poor performance, without a history of an abnormal respiratory noise, was of little value. The technique, in conjunction with arterial blood gas measurements, was useful in determining the efficacy of surgical treatment of laryngeal hemiplegia.  相似文献

Racing performance of Thoroughbred horses after arthroscopic surgery of the carpus     

NJ KANNEGIETER  N. RYAN† 《Australian veterinary journal》1991,68(8):258-260

The case record, and subsequent racing performance, of 110 horses that had undergone arthroscopic surgery of the carpus, were reviewed. Of these, 87% resumed racing, with 43% able to win at least one race, after surgery. Horses with chip fractures from the distal radius had the best prognosis, while horses with sagittal fractures of the third carpal bone had the poorest. The performance of horses with bilateral lesions was similar to those with unilateral lesions. It was concluded that arthroscopic surgery was a suitable technique for the diagnosis and treatment of carpal lesions in the horse.  相似文献   

The incidence and severity of intercarpal ligament damage in the equine carpus     

NJ KANNEGIETER  SA COLGAN 《Australian veterinary journal》1993,70(3):89-91

SUMMARY The arthroscopic findings in 104 intercarpal joints in 76 horses were reviewed to determine the incidence and severity of changes in the medial intercarpal ligament. Damage to the intercarpal ligament was observed in 43 joints in 35 horses, ranging from mild fraying of the edges of the ligament to complete disruption of all fibres. This represented an incidence of 41% of joints being affected. In 9 joints examined arthroscopically primarily as a further diagnostic procedure, ligament damage was evident in all cases. In horses undergoing arthroscopic surgery primarily for the treatment of osteochondral chip or slab fractures, there was some correlation between the severity of articular cartilage damage and the presence of ligament damage.  相似文献

Risk factors for nuisance barking in dogs   总被引：1，自引：1，他引：0  

NJ Cross  K Rosenthal  CJC Phillips 《Australian veterinary journal》2009,87(10):402-408

Objective   To determine the key variables related to the environment, animal and owner that influence nuisance barking by dogs in a city with a subtropical climate.
Design and Population   A case–control survey of dog owners in Brisbane, Queensland, was conducted using a questionnaire investigating key variables connected to nuisance barking. Owners of dogs exhibiting nuisance barking were obtained from a list of dogs being treated in a Brisbane behaviour clinic, and those of control dogs were selected from a telephone directory.
Results   Univariate analysis showed that animal, owner and environmental factors all potentially influence the occurrence of nuisance barking. Multivariate analysis identified the following factors, with the relevant odds ratios (OR) as significant: age of the dog (young dog vs old dog, OR 11.2); multiple dogs in the household vs single (OR 5.6); origin of the dog (home bred vs obtained from breeder or friend, OR 4.0); type of dog, (herding vs other types, OR 3.2) and dog with access to the home vs dog without access (OR 2.5).
Conclusion   The greatest risk for nuisance barking occurs with a young dog of the herding type that is home bred and with access to the house in a multiple dog household.  相似文献
