THE PLACE OF VETERINARY ANAESTHESIA IN "THE FUTURE ROLE AND EDUCATIONAL NEEDS OF THE VETERINARY PROFESSION" AND RECOMMENDATIONS REGARDING FRAMEWORK OF EMPLOYMENT OR POSTGRADUATE TRAINING IN VETERINARY ANAESTHESIA

I would say that the ultimate position holders of the D.V.A. find themselves in, is very largely dependent on the course of events over the next few years and in no small measure to their own endeavours. I feel that the holders of the D.V.A. should view this training period as one in which they have enlarged their own over all appreciation of the subject they have studied and have therefore, gained for themselves a material advantage over other members of the profession who have not in fact followed this line of study and that although there is a certain amount of despondency in the ranks of the veterinary anaesthetists at the moment, this should not be allowed to become an obstacle in the progressive development of this group.     

THE ROLE OF ULTRASOUND IN THE ASSESSMENT OF LARYNGEAL PARALYSIS IN THE DOG

Forty dogs with clinical signs suggestive of upper respiratory tract disease underwent echolaryngography and laryngoscopy. Laryngoscopy was used as the definitive technique to diagnose laryngeal paralysis. The ultrasound investigation accurately indicated the presence of the paralysis and confirmed the uni- or bilateral nature of the disorder. Findings indicative of laryngeal paralysis included asymmetry or absence of motion of the cuneiform processes (30/30), abnormal arytenoid movement (16/30), paradoxical movement (9/30), caudal displacement of the larynx (2/30) and laryngeal collapse (1/30). Thirty dogs were found to be afflicted with laryngeal paralysis and ten had normal laryngeal motility.     

MORPHOLOGICAL PREPARATIONS OF VALUE TO THE VETERINARY SURGEON

The preservation of dissections by drying is centuries old but the technique is much improved by modern methods of embalming, complete degreasing, selective bleaching, spacing of parts and coloring. The preparation techniques require painstaking attention to detail but the results are gratifying. The finished specimens are most instructive in the hands of the teacher, surgeon and clinician.     

INADVERTENT INTRATHECAL ADMINISTRATION OF DIATRIZOATE MEGLUMINE AND DIATRIZOATE SODIUM DURING MYELOGRAPHY IN A DOG

A dog undergoing diagnostic myelography inadvertently received 0.5 ml diatrizoate meglumine (66%) and (10%) diatrizoate sodium via intrathecal injection. This resulted in post-operative seizures requiring extended sedation of the patient. The clinical course and management of this patient are presented. Complications associated with the inappropriate administration of a hyperosmolar contrast agent into the subarachnoid space and the results of similar accidents in humans are also discussed. The dog in the report recovered with no evidence of long trem neurological dam     

PREVALENCE OF CANINE HIP DYSPLASIA IN A VETERINARY TEACHING HOSPITAL POPULATION

The purpose of this study was to determine the prevalence of canine HD in a population in which there was minimal or no prior screening of radiographs for the disorder. Patient information was obtained from the radiographic database at the University of Missouri-Columbia Veterinary Teaching Hospital during the five-year period of 1991-1995. The coxofemoral joints on ventrodorsal radiographs of the pelvis were independently evaluated by three veterinary radiologists. A consensus evaluation of normal, borderline, or dysplastic was compiled. There were 2885 dogs identified representing 116 breeds and the mixbreds. There were 2236 purebred dogs (1071 males and 1165 females) and the prevalence of HD was 19.7%. There were 649 mixbred dogs (340 males and 309 females) and the prevalence of HD was 17.7%. There was no significant difference in the prevalence of HD between sexes or between purebred and mixbred dogs (P = 0.16; P = 0.29). Degenerative joint disease (DJD) was the most common radiographic manifestation of HD and there appeared to be a threshold at 12 months of age after which the presence of DJD was the primary diagnostic criteria.     

INPACTION OF THE PHARYNX, LARYNX, AND ESOPHAGUS BY AVIAN BONES IN THE DOG AND CAT

Avian osseous (mandible, thoracic and caudolateral processes and furculum) foreign body impaction in the larynx, pharynx, and esophagus is described in three cats and one dog. All animals were presented because of gagging. Radiographic assessment revealed the foreign body in each animal. Each foreign body was successfully removed. Three of the animals recovered uneventfully, and one had a persistent change of voice.     

ARTERIOGRAPHIC ANATOMY OF THE ABDOMINAL AORTA IN THE GOAT, DOG, PIG, AND RABBIT

Arteriographic anatomy of the major branches of the abdominal aorta of rabbits, dogs, pigs, and goats was investigated. The origin and location of the celiac, cranial mesenteric, right renal, left renal, caudal mesenteric, and external iliac arteries were demonstrated, and their placement was described in relation to the iliac bifurcation and lumbar vertebral bodies.
