Introduction: Motor vehicular trauma, bite wounds, high-rise syndrome, and trauma of unknown origin are common reasons cats present to the emergency service. In small animals, thoracic injuries are often associated with trauma. The objective of this retrospective study was to evaluate limits of agreement (LOA) between thoracic point-of-care ultrasound (thoracic POCUS) and thoracic radiography (TXR), and to correlate thoracic POCUS findings to animal trauma triage (ATT) scores and subscores in a population of cats suffering from recent trauma. Methods: Cats that had thoracic POCUS and TXR performed within 24  h of admission for suspected/witnessed trauma were retrospectively included. Thoracic POCUS and TXR findings were assessed as “positive” or “negative” based on the presence or absence of injuries. Cats positive on thoracic POCUS and TXR were assigned 1 to 5 tentative diagnoses: pulmonary contusions/ hemorrhage, pneumothorax, pleural effusion, pericardial effusion, and diaphragmatic hernia. When available ATT scores were calculated. To express LOA between the two imaging modalities a kappa coefficient and 95% CI were calculated. Interpretation of kappa was based on Cohen values. Results: One hundred and eleven cats were included. 83/111 (74.4%) cats were assessed as positive based on thoracic POCUS and/or TXR. Pulmonary contusion was the most frequent diagnosis. The LOA between thoracic POCUS and TXR were moderate for all combined injuries, moderate for pulmonary contusions/ hemorrhage, pneumothorax, diaphragmatic hernia, and fair for pleural effusion. Cats with positive thoracic POCUS had significantly higher median ATT scores and respiratory subscores compared to negative thoracic POCUS cats. Discussion: The frequency of detecting intrathoracic lesions in cats was similar between thoracic POCUS and TXR with fair to moderate LOA, suggesting thoracic POCUS is useful in cats suffering from trauma. Thoracic POCUS may be more beneficial in cats with higher ATT scores, particularly the respiratory score. [ABSTRACT FROM AUTHOR]

Objective: To report a case of rhabdomyolysis and myoglobinuria following single induction dose of propofol in a dog. Case Summary: A 5‐year‐old intact male Shih‐Tzu dog was presented for pigmenturia occurring a few hours following anesthesia for comprehensive oral health assessment and treatment. After premedication with IV diazepam (0.5 mg/kg), anesthesia was induced with IV propofol (4 mg/kg) and maintained with isoflurane vaporized in oxygen. A few hours following recovery from anesthesia, the dog developed rhabdomyolysis and myoglobinuria associated with increased serum alanine aminotransferase and C‐reactive protein concentrations, as well as mild hypokalemia and euglycemic glycosuria. Approximately 48 hours after IV fluid therapy, the dog was clinically normal, and myoglobinuria progressively resolved. New or Unique Information Provided: This is the first case description of rhabdomyolysis and myoglobinuria following a single dose of injectable propofol. [ABSTRACT FROM AUTHOR]

A 14‐month‐old entire male Saint Bernard dog was presented at the emergency department for paralysis after a head trauma. Computed tomography examination revealed an atypical fracture of C6 with a large free bone fragment in the dorsolateral part of the vertebral canal, originating from the vertebral body. A C6–C7 Funkquist B dorsal laminectomy was performed to remove this intracanalar fragment. A dorsal stabilization using lag screws inserted into the articular facets of C5–C6 and C6–C7 was also performed. The surgical procedure maintained vertebral column stability and allowed a complete functional recovery. The present article exposes the diagnosis and therapeutic management of an original cervical fracture, discusses the choice of a stabilization technique for the caudal cervical spine and the possible underlying predisposing factors that could have led to this unusual fracture.

Background: Blood typing for the A and B antigens is essential and crossmatching testing is generally recommended before transfusing blood to cats. Objective: To evaluate 2 crossmatch (XM) tests. Animals: Forty‐nine healthy domestic shorthair cats that had not received a blood transfusion. Methods: Prospective study. Blood samples were typed for AB using immunochromatographic and flow cytometric techniques. A gel column (GC) and a feline antiglobulin‐enhanced gel column (AGC) XM tests were used for crossmatching. Results: The population included 34 type A, 13 B, and 2 AB cats, with concordant results (r = 1, P < .005) by flow cytometry and immunochromatographic strip kit. The plasma from type A cats had either no or weak anti‐B alloantibodies. The plasma of 12 of 13 type B cats contained strong anti‐A alloantibodies. For crossmatching, plasma to RBC pairings were prepared using the GC (n = 446) and AGC (n = 630) tests. Both methods showed compatibilities in 329 and incompatibilities in 102 pairings including all A‐B mismatches. Additionally 15 pairings showed agglutination by the AGC but not GC method. Fourteen incompatibilities outside the expected A‐B mismatches were only revealed by AGC. Conclusions and Clinical Importance: AB typing using immunochromatographic strip is as accurate as laboratory flow cytometry. The 2 XM methods had good agreement with additional incompatibilities being recognized by the AGC XM beyond A‐B incompatibilities. In clinic, feline AB typing and sensitive XM test kits are available and recommended before each transfusion, although the clinical implications of incompatible XM test results and clinical benefits of such crossmatching have not been documented.

Background: Cardiovascular dysfunction associated with acute kidney injury has been recently described in veterinary medicine, but limited information is available for cats with urinary tract obstruction (UTO)., Objective: This retrospective study aimed to describe the type, frequency, timeline, and risk factors for cardiovascular events (CVEs) in cats treated for acute UTO., Animals and Procedures: Medical records of cats admitted to the intensive care unit for either upper (ureteral: UUTO) or lower (urethral: LUTO) UTO from 2016 to 2021 were reviewed. Cardiovascular events were defined as development of arrhythmia, heart murmur or gallop sound, clinical signs consistent with fluid overload (CRFO), or decreased tissue perfusion (DTP)., Results: One hundred and sixty-eight cats with UTO were recruited (56 with UUTO and 112 with LUTO). Cardiovascular events were reported in 61.9% of cases, including arrhythmia (33.6%), gallop rhythm (28.1%), heart murmur (15.3%), CRFO (14.4%), and DTP (8.6%). Potassium concentration, preexisting chronic kidney disease, and renal pelvic dilation at abdominal ultrasonography were associated with CVE occurrence in multivariate analysis., Conclusions: This study highlighted frequent CVEs in cats treated for UTO, with a potential strong impact on outcome. Therefore, cardiovascular parameters of cats with preexisting chronic kidney disease or those admitted with hyperkalemia or renal pelvic dilation should be closely monitored., (Copyright and/or publishing rights held by the Canadian Veterinary Medical Association.)

Objectives: The aims of this study were to update the prevalence of different feline blood types in the Lyon (France) area, as well as to determine the risk of mismatched transfusion (MT) and neonatal isoerythrolysis (NI) in kittens with parents of unknown blood type., Methods: Blood samples were obtained from blood donor cats and cats admitted to an intensive care unit in Lyon. AB blood typing was performed using an immunochromatographic strip. The risk of MT was estimated by adding the risk of a major transfusion reaction and the risk of a minor transfusion reaction. The risk of NI was estimated according the equation (p²)(q²) + 2pq(q²), with q being the b allele frequency and p = 1 - q. The results were analysed by absolute and relative frequency analysis and multivariate analysis., Results: The cohort study population included 320 non-pedigree cats and 37 pedigree cats. The prevalence of blood types A, B and AB was 84.3%, 14.0% and 1.7%, respectively. Considering non-pedigree cats, the prevalence of types A, B and AB was 83.7%, 14.4% and 1.9%, respectively. There were no significant differences of blood type distribution by sex ( P = 0.73) or by breed ( P = 0.90). Based on these percentages, the risks of MT and NI in non-pedigree cats were 24.3% and 12.3%, respectively., Conclusions and Relevance: The prevalence of type B cats is high in the Lyon area and associated with high risks of MT and NI. These results confirm the importance of performing blood typing prior to any blood transfusion or mating., Competing Interests: Conflict of interest: M Guidetti was employed by, and I Goy-Thollot has been a scientific advisor to, Dianov. Reagents for this study were donated by Alvedia, which is a commercial supplier of blood typing and cross-match kits. However, the study design and execution, as well as data analysis and manuscript writing, were performed independently.
