摘要:

ABSTRACTA simple ultrasonographic method of estimating liver size in the dog was evaluated in this study. A single linear measurement from the tip of the ventral liver lobes to the diaphragm was made, using both transverse and longitudinal planes of section, Assuming careful technique, this measurement proved to be highly reproducible. There was good correlation between the measurements taken on the two planes of section. This measurement was shown to provide a good indicator of liver mass, irrespective of the size or breed of dog. It was concluded that ultrasound provides a simple, quantitative method of assessing liver size in the dog.

摘要:

ABSTRACTUltrasonographic estimations of liver size were made in each of 100 normal adult dogs. A correlation coefficient of 0.78 was found between the single linear hepatic measurement selected and bodyweight. The relationship between liver size and bodyweight was found to be approximately linear, with no apparent departure from linearity at extremes of bodyweight. The sex of the animal did not affect liver size once bodyweight had been taken into account. Deep, narrow‐chested dogs tended to have a slightly greater liver measurement for a given bodyweight than shallow, wide‐chested dogs, but this difference was small compared to the variation seen between individuals of the same body type and weight. Thus a graph could be constructed, with 95 per cent confidence limits, allowing prediction of the normal range of liver sizes for a given bodyweight. This graph may be applied to adult dogs of either sex and any breed conformation within the weight range of 1 to 60

摘要:

ABSTRACTThe history of the introduction of muscle relaxants into medical and veterinary anaesthesia is discussed. It is interesting to note that the compounds were used in animals for therapeutic purposes some 100 years before their introduction into human anaesthetic practice. The concept of the triad approach to anaesthesia by separate consideration of the three components of narcosis, reflex depression and muscle relaxation is considered. The properties of the depolarising and non‐depolarising muscle relaxant drugs are described. The only depolarising relaxant which is in common use is suxamethonium which produces an initial depolarisation of the muscle end‐plate which is accompanied by fasciculation of muscle and is non‐reversible. There are a number of non‐depolarising or competitive muscle relaxants which are available for use in the dog. They are reversible by anticholinesterase drugs and are potentiated by volatile anaesthetic agents. The properties of the more recently introduced compounds atracurium besylate and vecuronium bromide are considered in the light of their differences when compared with the older co

摘要:

ABSTRACTSixty cases of canine sialocoele were reviewed from the records of the Sydney University Veterinary Teaching Hospital. Poodles, dachshunds and Australian silky terriers were significantly over represented in the survey when compared to the hospital sample population (P&0.01). No other statistically significant breed, sex, or age trends were noted. Neoplasia was associated with sialocoele formation in three cases. The sialocoele location was cervical (42), sublingual (four), pharyngeal (four), not recorded (one) or in more than one site (nine). Thirty‐five of 39 surgically treated cases were managed by extirpation of the mandibular and sublingual salivary glands together with drainage. Few complications were recorded. Forty‐two per cent of the cases had received previous veterinary treatment in the form of drainage alone. Drainage of saliva from sialocoeles without removal of the offending salivary glands is inappropri

摘要:

ABSTRACTA flexural deformity affecting one or both forelimbs identified in 21 puppies of six to 12 weeks of age closely resembled a condition which has long been known in foals and farm animals at birth or shortly afterwards. In the puppies the characteristic feature was carpal hyperflexion which was associated with tautness of the tendons of the flexor carpi ulnaris muscle. The majority recovered spontaneously with conservative management but in two puppies it was necessary to section the shortened tendons to enable a normal limb posture to be regained. The fact that there was a preponderance of dobermann pinschers (17 out of 21) in the group opens speculation about an hereditary factor being involved, but further study is needed before such a correlation can be reached.
