Fast recognition, ECG-guided stabilization, and cause-directed therapy improve survival.</p><p><strong>Animals and procedure: </strong>Part 2 of this 2-part review gives a patient-side approach for recognition, confirmation, and emergency treatment of hyperkalemia. It integrates current veterinary evidence and core physiology into step-by-step guidance for ECG interpretation, point-of-care testing, drug selection, and monitoring. It also maps 1st-hour priorities to common etiologies such as urethral obstruction and hypoadrenocorticism.</p><p><strong>Results: </strong>Immediate cardioprotection with intravenous calcium treats cardiotoxicity. Potassium decreases rapidly with regular insulin plus dextrose, β₂ agonists serve as adjuncts, and bicarbonate is reserved for severe acidemia. Potassium elimination follows with balanced crystalloids and, when needed, renal replacement therapy. After initial stabilization, durable correction depends on identifying and treating the underlying cause and removing excess potassium from the body. Close glucose surveillance prevents late hypoglycemia after insulin. For urethral obstruction, prompt unblocking and fluids often normalize potassium with little need for repeat shifting drugs. For Addisonian crisis, fluids and glucocorticoids correct the driver while potassium decreases.</p><p><strong>Conclusion and clinical relevance: </strong>Use a consistent sequence: Verify true hyperkalemia, protect the heart, shift potassium, remove potassium, and fix the cause. Pair ECG findings with serum potassium concentrations to guide action, since ECG stages do not always match absolute potassium concentrations.

{"title":"Successful hemodialysis treatment of suspected acorn toxicosis in a Bedlington terrier.","authors":"Soyoung Jung, Woonchan Ahn, Taeho Lee, Aryung Nam","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>A 17-month-old neutered male Bedlington terrier weighing 5.4 kg was presented because of vomiting, lethargy, and oliguria. Serum chemistry analysis revealed severe azotemia and ultrasonography revealed hyperechoic renal cortices. Acorn-induced acute kidney injury was suspected based on the animal's history of eating dried acorns over the previous 8 d. The dog did not respond to conventional intravenous fluid therapy, but his condition improved with intermittent hemodialysis. Although acorn intoxication is well documented in grazing animals, including cattle, it has rarely been reported in dogs. Acorns can cause acute kidney or liver injury, with high mortality rates. To the best of our knowledge, this is the first reported canine case of acorn toxicosis successfully treated with hemodialysis. The case findings indicate the importance of raising awareness among pet owners about the potential life-threatening effects of consuming acorns, particularly in regions where animals' exposure to acorns is likely. Key clinical message: Acorn ingestion can cause life-threatening acute kidney injury in dogs. Early recognition and timely intervention with hemodialysis can result in successful outcomes.</p>","PeriodicalId":9429,"journal":{"name":"Canadian Veterinary Journal-revue Veterinaire Canadienne","volume":"67 5","pages":"516-520"},"PeriodicalIF":1.0,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13142069/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147834083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
