Large-volume pneumoperitoneum and septic peritonitis secondary to splenic abscess rupture in a dog.

An 11-year-old spayed female American pit bull terrier mixed breed dog was presented because of hyporexia and abdominal distension. The dog had large-volume free peritoneal gas on imaging and septic neutrophilic exudate on abdominocentesis. Exploratory laparotomy revealed a ruptured splenic mass draining purulent material. A splenectomy was performed and the abdomen was lavaged. Culture samples grew an anaerobic Gram-positive rod. The dog was discharged 4 days after surgery with no residual problems noted 1 week later. To our knowledge, this is the first report of large-volume pneumoperitoneum and septic peritonitis secondary to rupture of a splenic abscess.

Pneumopéritoine de grand volume et péritonite septique secondaire à la rupture d'un abcès splénique chez un chien. Une chienne stérilisée de race pitbull terrier américain croisée âgée de 11 ans fut présentée à cause d'hyporexie et de distension abdominale. Lors de l'examen par imagerie on nota un large volume de gaz péritonéal libre et un exsudat neutrophilique septique lors de l'abdominocenthèse. Une laparotomie exploratoire révéla une masse splénique rupturée qui drainait du matériel purulent. Une splénectomie fut réalisée, et l'abdomen fut soumis à un lavage. La culture d'échantillons permis la croissance d'un bâtonnet à Gram-positif anaérobie. Le chien reçu son congé 4 jours après la chirurgie et aucun problème résiduel ne fut noté 1 semaine plus tard. À notre connaissance il s'agit du premier rapport d'un pneumopéritoine de grand volume et de péritonite septique secondaire à la rupture d'un abcès splénique chez un chien.(Traduit par Dr Serge Messier).

Correlation between thromboelastography and traditional coagulation test parameters in hospitalized dogs.

A hospital-based, prospective cross-sectional study was used to compare kaolin-activated thromboelastography (TEG) parameters with traditional coagulation tests in 29 hospitalized dogs. Cases were included if the attending clinician requested coagulation testing. Blood was obtained from each dog and coagulation (prothrombin time, partial thromboplastin time, antithrombin activity, d-dimer concentration, and fibrinogen concentration) and TEG analyses were performed. Hematocrit (Hct) was also measured. Traditional coagulation results were evaluated for correlation with those from kaolin-activated TEG. Spearman's correlation was used to calculate correlation coefficients. Fibrinogen was positively correlated with maximum amplitude (Pearson r=0.72, P<0.001) and global clot strength (Pearson r=0.72, P<0.001). There was no correlation between any of the remaining coagulation variables, TEG parameters, or Hct. Results of kaolin-activated TEG and traditional coagulation tests are not interchangeable means of monitoring coagulation derangements in this intensive care unit patient population. Determination of a true outcome measure is necessary to establish TEG's clinical relevance to veterinary medicine.

Severe hyperkalemia presenting with wide-complex tachycardia in a puppy with acute kidney injury secondary to leptospirosis.

OBJECTIVE: To describe a case of hyperkalemia coinciding with wide-complex tachycardia (WCT) in a dog with acute kidney injury secondary to leptospirosis infection. CASE SUMMARY: An 11-week-old Golden Retriever-Standard Poodle cross puppy was referred for acute kidney injury and hepatopathy. WCT coinciding with marked hyperkalemia was identified on presentation. Tachycardia persisted until resolution of hyperkalemia. NEW OR UNIQUE INFORMATION PROVIDED: To our knowledge, this is the first report of severe hyperkalemia presenting with WCT in a dog. Hyperkalemia should be considered a differential for WCT in dogs.
