摘要:

SummaryThe purpose of this study is to report on five cases of coral snake envenomation in the dog to substantiate earlier findings in four dogs reported previously, and to describe any additional clinical features that have not yet been noted. The combined results from both studies allow for a more accurate projection of the frequency of certain clinical signs. Both groups showed signs of lethargy, lower motor neuron weakness (8 of 9 dogs) and varying hematologic changes with hemolysis and hemoglobinuria occurring most commonly (7 of 9 dogs). Cardiac dysrhythmias were recorded infrequently (2 of 9 dogs). Not reported previously was the presence of a subtle bite wound located on the upper or lower lip of three dogs in the present series. An unexpected finding in this second series was the occurrence of an anaphylactoid reaction in one dog presumably attributed to the antivenin. Close examination of the lip might reveal the site of envenomation (as found in 4 of 9 dogs from both studies). Treatment with coral snake antivenin should be given as early as possible and followed by close observation for signs of anaphylaxis. The results of this study substantiate earlier findings and provide for a larger data base for further reference.

摘要:

SummaryAlterations in thyroid indices in critically ill dogs were studied retrospectively to determine the incidence of the euthyroid sick syndrome and to assess its prognostic relevance to survival. Sixty‐seven dogs were classified as euthyroid bases on a TSH stimulation test. Forty‐one of 67 (61%) of the euthyroid dogs had low baseline serum T4concentrations (<1.5 ug/dl) and 38 of 67 (56%) of the euthyroid dogs had low baseline serum T3concentrations (<75 ng/dl). There was no significant difference between either the baseline or the post‐stimulation serum T4concentrations when values of dogs that survived were compared with those that died. There was, however, a significant difference (P<0.05) between both the baseline and the post‐stimulation values for T3 when survivors (100.3± 81 ng/dl, 143± 66 ng/dl) and non‐survivors (64.2 ± 17.1 ng/dl, 96.6 ± 38.3 ng/dl) were compared. The euthyroid sick syndrome occurs commonly in critically ill dogs. Further, the extent of depression of serum concentrations of T3may be correlated

摘要:

SummaryA technique is described which is particularly useful in obese or heavily muscled animals when a single lumen tracheostomy tube is used, or when mechanical ventilation through a cuffed tracheostomy tube is required. The technique assures easy access to a large tracheal stoma which facilitates cleaning and tube replacement.

摘要:

SummaryThe medical records of animals with pancreatitis that received nutritional support were evaluated. Over a five year period (1989–1994), 16 patients with pancreatitis (14 dogs and 2 cats) received nutritional support. Affected animals commonly exhibited vomiting, diarrhea, and weight loss, as well as multiple clinicopathological abnormalities.Total parenteral nutrition (TPN) was used in 13 of the cases, while two animals received partial parenteral nutrition (PPN), and one was fed through a jejunostomy tube. The duration of nutritional support ranged from one to 13 days, with a mean of 6.6 days. Three of the animals receiving TPN had complications resulting from the nutritional support, including hyperglycemia, hyperammonemia, and hyperlipidemia. The survival rate for all 16 cases was 56% (9 of 16).A variety of nutritional support techniques can be successfully used in animals with pancreatitis and are associated with few complications, most of which can be managed with adjustments in treatment regime

摘要:

SummaryCanine high‐risk surgical patients were identified, and the variables that distinguished between survivors and nonsurvivors were determined. Fifty‐two nonsurvivors and 176 survivors were randomly drawn from a population of 615 dogs undergoing general surgical procedures and entering the intensive care unit. Forty‐two variables were examined to determine which variables were significantly different between nonsurvivors and survivors. Properative variables that were significantly different were age, hospital days prior to surgery, the number of concurrent diseases, American Society of Anesthesiologists (ASA) status, PCV, TP, platelet count, albumin concentration, alkaline phosphatase activity, bilirubin concentration, and surgery site (laparotomy = highest risk). Age, PCV, TP, platelet count, albumin concentration, alkaline phosphatase activity, and bilirubin concentration were then examined, using stepwise logistic regression for their ability to predict mortality in a separate population of 169 canine patients undergoing laparotomy. Age, TP, and platelet count were identified as predictive vari

摘要:

SummaryGastric dilatation‐volvulus (GDV) was surgiclly induced in 10 dogs. Five of the dogs were pretreated with 50 mg/kg PO of allopurinol to determine the effect of xanthine oxidase inhibition on the pathophysiology of GDV. After 150 minutes, the GDV was corrected, and lactated Ringer's solution was administered intravenoulsy (resuscitation). Two hundred forty minutes after relief fo GDV, the dogs were euthanatized without recovery from anesthesia. Administration of allopurinol was associated with a reduced (P<0.01) incidence of hepatic necrosis and a lower (P<0.045) serum phosphorus level than observed in the control group at the end of the experiment. The increase in base deficit in the allopurinol‐treated group after resuscitation was also less(P<0.045) than the control group. In conclusion, this study suggests that inhibition of xanthine oxidase‐derived oxygen free radicals protects against hepatic necrosis in dogs with GDV. Resuscitation appears to be a time of profound physiologic stress for dogs wit

摘要:

SummaryGreater awareness of the benefit of medical management of neoplasia has resulted in greater client demand for therapy and increased use of chemotherapy by practitioners. Complications of anticancer therapy, therefore, can be expected to an increasing complaint of clients contacting emergency and critical Care facilities. The efficacy of chemotherapy consists of a does dependent cytotoxic effect on rapidly dividing neoplastic cells. As these drugs charcteristically have a narrow therapeutic to toxic ratio, damage to normal host tissues is the major risk with aggressive protocolos. The most common adverse effects are myelosuppression with fever and spesis secondary to neutropenia and gastrointestinal toxicity with vomiting or diarrhea. With awareness of the toxicity of specific anticancer durgs, the practicing emergency clinician can rationally intervene to overcome what is often short term, but life‐threatening crisi
