    Abstract Objective: To describe the placement of a subcutaneous catheter in a dog for the management of severe subcutaneous emphysema secondary to severe laryngeal crushing injury and temporary tracheostomy tube placement.
    Case summary: A 6-year-old male neutered Kelpie suffered a severe laryngeal crushing injury following a dog attack. Case management included the placement of a temporary tracheostomy tube due to severe respiratory compromise and inspiratory dyspnea associated with the crush injury. During hospitalization, the patient developed severe subcutaneous emphysema, pneumomediastinum, and a pneumothorax as a complication of the laryngeal crushing injury and temporary tracheostomy. A subcutaneous catheter was placed to manage the recurrent subcutaneous emphysema while the tracheostomy stoma healed. Five months posttrauma, the dog returned to normal with mild stridor during excitement and while panting.
    New or unique information provided: This is the first report in veterinary medicine describing the use of a subcutaneous catheter for the management of subcutaneous emphysema secondary to laryngeal crush injury and temporary tracheostomy tube placement.

    Abstract OBJECTIVE: To describe new onset of generalized seizures in 3 young dogs following cessation of a benzodiazepine‐containing sedation protocol to facilitate mechanical ventilation (MV) for hypoxemia. SERIES SUMMARY: Three dogs under 5 months of age underwent MV due to severe hypoxemia. All 3 dogs were sedated with a constant rate infusion of benzodiazepines as part of their sedation protocol to facilitate MV. All 3 dogs had an acute onset of generalized seizures within 36 hours of sedation cessation and weaning from MV. All 3 dogs’ seizures were successfully managed with a slow, tapering course of benzodiazepines. One dog was additionally treated with levetiracetam at the time of initial seizure activity, which was discontinued 1 year following discharge and absence of ongoing seizure activity. All 3 dogs were discharged successfully with no reports of ongoing seizures or neurologic deficits after discharge. NEW OR UNIQUE INFORMATION PROVIDED: Young dogs managed with benzodiazepines to facilitate MV may have acute onset of generalized seizures following cessation, which can be successfully managed with short‐term benzodiazepine therapy. The 3 cases in this series demonstrated a positive outcome and were successfully managed following acute onset of generalized seizure activity post‐MV.

    Abstract Objective: To report the use of manual therapeutic plasma exchange (TPE) in a dog with severe carprofen toxicity.
    Summary: A 12-year-old neutered female Pembroke Welsh Corgi weighing 20 kg was evaluated after ingesting 223 mg/kg of carprofen. Emesis was attempted with apomorphine at the primary care veterinarian but was unsuccessful, and a dose of activated charcoal with sorbitol was administered. On presentation to the referral center, approximately 8 hours after ingestion, the dog's physical examination revealed mild abdominal discomfort but was otherwise unremarkable. Treatment consisted of a combination of supportive care including activated charcoal with sorbitol, cholestyramine, IV lipid emulsion, and manual TPE. Blood samples were collected prior to the initiation of manual TPE and at the completion of 12 exchange cycles. Carprofen levels were determined by high-pressure liquid chromatography. A 57% decrease in carprofen levels was achieved with the combination of activated charcoal, cholestyramine, IV lipid emulsion, and manual TPE. The dog did not develop organ dysfunction secondary to toxicity and was discharged 4 days after ingestion.
    New or unique information provided: This report describes the successful decrease of plasma carprofen in a dog with the combination of decontamination techniques and manual TPE. While TPE has been previously reported as a successful therapeutic in dogs with nonsteroidal anti-inflammatory toxicity, including carprofen, equipment and expertise of this platform is not readily available. Manual TPE is technically simple and can be performed in any hospital with a large blood centrifuge.

    Abstract OBJECTIVE: To describe the successful case management of an extradural hematoma secondary to anticoagulant rodenticide toxicity causing spinal compression and paraplegia. CASE SUMMARY: A 3‐month‐old, female intact, mixed breed dog was presented for a 12‐hour history of paraplegia. CBC and biochemistry results were unremarkable, and a coagulation panel revealed prolonged prothrombin time with normal activated partial thromboplastin time. Magnetic resonance imaging revealed an extradural compressive lesion within the vertebral canal extending from T6 to T11, most consistent with an extradural hematoma. Further coagulation testing revealed a coagulopathy caused by vitamin K1 deficiency and confirmed exposure to the anticoagulant rodenticide, diphacinone. The dog was medically managed with fresh frozen plasma, aminocaproic acid, and oral vitamin K1 therapy. A right‐sided T6 to T11 hemilaminectomy was later performed for removal of the extradural hematoma and spinal decompression. The dog's neurological status gradually improved postoperatively and, at the time of discharge, was nonambulatory paraparetic with voluntary micturition. Four weeks postoperatively, the dog had normal prothrombin and activated partial thromboplastin times and was nonambulatory paraparetic with strong motor function. NEW OR UNIQUE INFORMATION PROVIDED: This is the first reported case of a dog with an extradural hematoma secondary to anticoagulant rodenticide causing spinal cord compression and neurological deficits. Surgical management of this case was successful and resulted in improvement of neurological signs. Extradural hematoma should be considered as a potential location of bleeding in rodenticide toxicity as well as a differential diagnosis in patients with neurological deficits.

    Abstract OBJECTIVE: To compare in vivo central venous hemoglobin saturation measurement (ScvO₂) using a fiber optic catheter with saturation calculated from blood gas analysis in critically ill dogs. DESIGN: Prospective observational study. SETTING: University veterinary teaching hospital intensive care unit. ANIMALS: A convenience sample of 20 dogs with severe illness. INTERVENTIONS: Dogs were instrumented with either a central venous catheter with an integrated fiber optic cable or a conventional catheter with a fiber optic probe inserted through its distal port. Baseline saturation was measured with the fiber optic system (FSO₂), then monitored continuously. Central venous blood was collected for analysis and FSO₂ was recorded by the principal investigator (PI) or nursing staff participating in data collection (staff) at baseline and at 1, 2, 3, and 6 hours. Hemoglobin oxygen saturation (SO₂) values calculated using human Bohr coefficients were taken directly from the analyzer (GPSO₂), and were also calculated using temperature‐correction and canine Bohr coefficients (RSO₂). MEASUREMENTS AND MAIN RESULTS: Ninety‐seven paired measurements from 20 dogs were analyzed. FSO₂ obtained by the PI (n = 41) had better agreement with both GPSO₂ (concordance correlation coefficient ρc = 0.926 vs 0.5562) and RSO₂ (ρc = 0.75 for PI vs 0.54) than did staff (n = 56). RSO₂ values were always smaller than GPSO₂. FSO2 ‐ GPSO₂ differences were smaller when measurements were collected by the PI versus Staff (mean difference 0.21 vs −6.6, respectively, P < 0.02). Thirty‐six of 41 FSO₂ values obtained by PI were within 5% of GPSO₂. CONCLUSIONS: Concordance between FSO₂ and either calculation method was low, but was better when performed by PI. The larger difference between methods when using RSO₂ suggests a positive bias by FSO₂. Difficulty obtaining stable measurements may have contributed to the poor concordance between methods within Staff.

    Abstract Practical relevance: Cardiopulmonary arrest (CPA) can occur in any veterinary or animal care setting and is a particular risk in scenarios involving ill, injured or anesthetized patients. Education of all staff on the prevention and recognition of CPA, as well as the performance of cardiopulmonary resuscitation (CPR), is vital to influencing outcome.
    Evidence base: While there is a plethora of information regarding CPA and CPR in human medicine, there are comparably few studies in the veterinary literature. Many of the current veterinary guidelines are extrapolated from human medicine or studies based on animal models. Ongoing work is needed to tailor guidelines and recommendations to our domestic feline (and canine) patients in a clinical setting.
    Aim: The aim of this article, which is intended for veterinarians in all areas of small animal practice, is to provide an evidence-based review of CPA and CPR in feline patients. The authors have drawn heavily on detailed recommendations published by the Reassessment Campaign on Veterinary Resuscitation (RECOVER) initiative - one of the few resources specific to the veterinary clinical setting - as well as reviewing the available peer-reviewed literature studies, in constructing this article. Among the topics discussed are recognizing and preventing CPA, staff training and clinic preparedness, basic life support and advanced life support interventions, and appropriate post-cardiac arrest care.
