Perioperative medical care for equine abdominal surgery     

S J Spier  D M Meagher 《Veterinary Clinics of North America: Equine Practice》1989,5(2):429-443

Rational perioperative management improves the success rate of abdominal surgery. Important aspects of management are discussed, including principles of fluid therapy, nutrition, intravenous catheterization, antimicrobial prophylaxis, and the use of nonsteroidal anti-inflammatory medication. Current advances in the area of immunotherapy are mentioned.  相似文献

Pathologic findings and pathogenesis of racetrack injuries   总被引：1，自引：0，他引：1  

R R Pool  D M Meagher 《Veterinary Clinics of North America: Equine Practice》1990,6(1):1-30

Many lesions of the musculoskeletal system of racing horses are either acute traumatic lesions or are chronic biomechanically induced lesions that become suddenly unstable and provoke acute clinical signs. The latter lesions along with those of DJD are much more common and are of much greater overall economic importance to the racing industry than are the acute traumatic injuries. Chronic biomechanical lesions occur at predictable sites and are the result of an imbalance between repetitive microtrauma sustained in athletic performance and adaptive repair mechanisms of skeletal tissues. The distribution of these lesions in the limbs reflects the patterns of biomechanical forces placed on the skeleton during work at racing speeds and, therefore, reflects the type of racing activity for which the horse was bred. Lesions result when there is a failure of the stressed skeletal structures to adapt to the biomechanical forces placed upon them. Rest or a reduction in the level of training activity permit the healing of many asymptomatic and presumably some symptomatic lesions of the bony tissues. Articular cartilage, tendons, and ligaments have a lower capacity to resolve the damage and return to normal structure and function.  相似文献

Radiographic aspects of exercise-induced pulmonary hemorrhage in racing horses   总被引：1，自引：0，他引：1  

John R.  Pascoe  BVSc  Timothy R.  O'Brien  DVM  PhD  John D.  Wheat  DVM  Dennis M.  Meagher  DVM  PhD 《Veterinary radiology & ultrasound》1983,24(2):85-92

Abnormal pulmonary radiopacities were identified in 13 racing horses in which a diagnosis of exercise-induced pulmonary hemorrhage (EIPH) had been confirmed. The lesions were in the caudal lung lobe in all horses; seven were on the right and three on the left, and the laterality for three could not be determined. In ten horses the opacities, which were large and peripherally located, obliterated the thoracophrenic angle. They merged with the silhouette of the diaphragm and had a circular or ovoid surface directed toward the hilum. The intensity of opacification of the consolidated areas varied, and they often were not sharply marginated. Dorsal displacement of the pulmonary arteries was noted in the region of the radiopacity in seven horses. Varying volumes of pleural effusion were observed in nine horses. Serial radiographic examinations were performed in seven horses. The pulmonary radiopacities cleared within ten days in two horses. In the remaining five horses, gradual resolution, characterized by a reduction in lesion size with improved margination, occurred during several months. The central region of the radiopaque lesion commonly had a patchy appearance, suggesting cavitation. Normal pulmonary vascular and interstitial markings were evident following complete resolution of these lesions. The cause of these abnormal pulmonary opacities has not been determined. Pathologic-radiologic correlations will be required to improve understanding of the pathophysiology of EIPH in the racing horse.  相似文献   

Surgical reconstruction of chronic coronary band avulsions in three horses     

M D Markel  G L Richardson  P R Peterson  D M Meagher 《Journal of the American Veterinary Medical Association》1987,190(6):687-688

Three adult horses were admitted with chronic coronary band avulsions of 2-, 3-, and 46-month durations, respectively. The hoof had a typical appearance in all 3 horses, with a spur of coronary band and associated horn growing at right angles to the hoof wall. Each horse was anesthetized, and the coronary band was reconstructed. Follow-up evaluation of the 3 horses (12, 15, and 23 months after surgery, respectively), revealed healing of all 3 avulsed coronary bands. Mild roughening of the hoof wall distal to the previous avulsion site was observed.  相似文献   

Survival after small intestine resection and anastomosis in horses   总被引：3，自引：0，他引：3  

M H MacDonald  J R Pascoe  S M Stover  D M Meagher 《Veterinary surgery : VS》1989,18(6):415-423

The authors examined factors influencing survival in 140 horses that recovered from anesthesia after small intestinal resection between 1968 and 1986, using Kaplan-Meier estimated survival curves and the Cox proportional hazards regression model. Seventy-two horses (51%) died during the initial postoperative period, 19 horses (14%) died after discharge from the hospital, 33 horses (24%) were alive, and 16 horses (11%) were classified as censored. Mean age at surgery was 8 years. Horses 15 years of age or older, Arabians and Stallions, were overrepresented in the hospital population. The most common reason for resection was strangulation of bowel through a mesenteric rent. The mean and 50% median survival times were 1540 and 27 days, respectively. Horses admitted after January 1, 1980, had a significantly longer survival than those admitted before that time. Survival was longer after anastomosis of two small intestinal segments than after anastomosis of a small intestinal segment to the cecum; however, the length of bowel resected and the method of anastomosis had no demonstrable influence on survival. Of the variables studied, the heart rates at presentation and 24 hours after surgery were the most accurate predictors of survival.  相似文献   

The Effect of Environment on Survival and Hatching of Heterodera avenae1     

J.W. Meagher 《EPPO Bulletin》1982,12(4):361-369

Eggs within cysts of Heterodera avenae are able to survive long periods of desiccation and can be held for several years at 5oC when stored at low relative humidity. While this provides an excellent means of storing the nematode for use in laboratory experiments, field experiments show that desiccated eggs are readily dispersed by wind. Tolerance to desiccation is similar in free and encysted eggs, which hatch at the same rate. When eggs are desiccated, water is withdrawn from the larva within the egg shell. If cysts are exposed to conditions favouring eclosion, subsequent desiccation reduces egg viability and larval emergence. The importance of defining pre-test conditions in survival studies is emphasized, and differences in the physiological state of eggs may explain different observations in Australian and European studies.  相似文献
