Abstract
BACKGROUND Thromboelastometry (TEM) provides a comprehensive overview of the entire coagulation process and has not been evaluated in heatstroke-induced coagulopathies in dogs. OBJECTIVES To determine the diagnostic and prognostic utility of TEM in dogs with heatstroke. ANIMALS Forty-two client-owned dogs with heatstroke. METHODS Prospective observational study. Blood samples for intrinsic and extrinsic TEM (INTEM and EXTEM, respectively) were collected at presentation and every 12 to 24 hours for 48 hours. Coagulation phenotype (hypo-, normo-, or hypercoagulable) was defined based on TEM area under the 1st derivative curve (AUC). RESULTS Case fatality rate was 31%. Median TEM variables associated with death (P < .05 for all) included longer INTEM clotting time, lower AUC at presentation and at 12 to 24 hours postpresentation (PP), lower INTEM alpha angle, maximum clot firmness, and maximum lysis (ML) at 12 to 24 hours PP, and lower EXTEM ML at 12 to 24 hours PP. Most dogs were normo-coagulable on presentation (66% and 63% on EXTEM and INTEM, respectively), but hypo-coagulable 12 to 24 PP (63% for both EXTEM and INTEM). A hypo-coagulable INTEM phenotype was more frequent at presentation and 12 to 24 PP among nonsurvivors compared to survivors (55% vs 15% and 100% vs 50%, P = .045 and .026, respectively). AKI was more frequent (P = .015) in dogs with hypo-coagulable INTEM tracings at 12 to 24 hours. Disseminated intravascular coagulation was more frequent (P < .05) in dogs with a hypo-coagulable INTEM phenotype and in nonsurvivors at all timepoints. CONCLUSIONS AND CLINICAL RELEVANCE Hypocoagulability, based on INTEM AUC, is predictive of worse prognosis and occurrence of secondary complications.

Abstract
Daboia (Vipera) palaestinae (Dp), accounts for most envenomations in humans and dogs in Israel. In humans envenomed by Dp, serum cholesterol concentration (sChol) is inversely correlated with envenomation severity. This study examined the utility of sChol upon admission in dogs envenomed by Dp as an envenomation severity and outcome marker. Data upon admission, including sChol, were retrospectively collected from the medical records of dogs with proven Dp envenomation. The study included 415 dogs. The mortality rate was 11%. The heart rate upon admission was higher in non-survivors than in survivors. Signs of bleeding or hematoma and circulatory shock signs were more frequent among non-survivors compared to survivors. sChol, the platelet count, and serum albumin concentration (sAlb) were lower, while serum creatinine concentration was higher among non-survivors. sChol and sAlb were moderately, positively, and significantly correlated. sChol was significantly, negatively, albeit weakly, correlated with the length of hospitalization and the heart rate. sChol was lower in dogs admitted >12 h post-envenomation than in those admitted later. In dogs, sChol upon admission is a potential marker of severity and outcome of Dp envenomation. The platelet count, sAlb, and sCreat might also be potential markers.

Abstract
OBJECTIVES Xenotransfusion is the transfusion of blood from one species to another. With varying availability of allogenic feline blood (AFB) and in emergency conditions, circumstances occur when canine blood is transfused to cats. This study aimed to characterise the indications, effectiveness, limitations, and acute and late transfusion-related adverse effects of canine blood xenotransfusion compared with matched AFB to anaemic cats, and their survival and longer-term outcome. METHODS This retrospective study (2013-2020) examined cats receiving canine blood xenotransfusions or AFB. RESULTS The study included 311 cats (xenotransfusion [X-group], n = 105; allotransfusion [A-group], n = 206). Xenotransfusion was more frequent among cats sustaining haemorrhage than in those with haemolysis (P <0.01) or hypoproliferative anaemia (P <0.001). Financial constraints were the most common reason to elect xenotransfusion (49%). The post-transfusion mean packed cell volume was higher (P <0.001) in the X-group (22%) compared with the A-group (18%), and also higher (P <0.001) at 48-96 h post-transfusion (23% vs 18%, respectively). Transfusion-related adverse effects (TRAEs) were more frequent (P = 0.001) in the X-group (37.1%) compared with the A-group (19.4%), as were delayed haemolytic transfusion reactions (85% vs 42.5%, respectively; P <0.001). Acute transfusion reactions (ATRs) were more frequent (P <0.001) in the A-group (60%) compared with the X-group (20%). TRAEs were unassociated with survival to discharge. The survival to discharge rate of the X-group (55%) was lower (P = 0.007) than in the A-group (73%), while post-discharge survival rates to 30 days of cats surviving to discharge were 90% and 88%, respectively (P = 0.85). CONCLUSIONS AND RELEVANCE Canine blood xenotransfusions to cats might save lives in emergency conditions when AFB is unavailable or blood typing is infeasible. The survival to discharge rate of the X-group was lower than that of the A-group. The longer-term survival rate of cats administered xenotransfusions and surviving to discharge from the hospital was good.

Abstract
Transient hypophosphatemia is often detected in humans following generalized tonic-clonic seizures (GTCS), and serum phosphorus concentration (sPi) serves as a marker to differentiate GTCS from syncope. The objective of this retrospective study was to assess the usefulness of hypophosphatemia as a diagnostic marker for GTCS in dogs. Eighty-seven and 26 client-owned dogs with GTCS or syncope, respectively, were enrolled. Dogs were included if the episode occurred ≤ 3 h from presentation, and if sPi and serum creatinine (sCr) were measured. Dogs were excluded if aged < 1 year or if sCr exceeded 176.8 μmol/L. There were no group differences in sCr. Hypophosphatemia (sPi ≤ 0.97 mmol/L) occurred in 28 dogs (32%) in the seizure group, and in no dogs in the syncope group. Median sPi was significantly (P < 0.001) lower in the seizure group (1 mmol/L, [range, 0.31-2.87 mmol/L]) compared to the syncope group (1.35 mmol/L [range, 0.97-2.71 mmol/L]). Furthermore, in dogs presented while seizing (n = 24/87; 28%) median sPi was significantly lower compared to those that were not (0.9 mmol/L [range, 0.3-1.74 mmol/L] vs. 1 mmol/L [range, 0.33-2.18 mmol/L], P = 0.050). ROC analysis of sPi as a marker of GTCS yielded an AUC of 0.757 (95% confidence interval 0.667-0.847), with an optimum cutoff point of 0.97 mmol/L, corresponding to specificity and sensitivity levels of 100% and 44%, respectively. In conclusion, sPi may, in certain cases, serve as an additional diagnostic tool to differentiate GTCS from syncope in dogs. Hypophosphatemia, especially with sPi < 0.97 mmol/L, may be useful in clinical practice to rule in GTCS.

Abstract
OBJECTIVE To describe the management of dogs with acute kidney injury (AKI) by continuous renal replacement therapy (CRRT), and to investigate the relationship between a prescribed CRRT dose, the hourly urea reduction ratio (URR), and the overall efficacy. ANIMALS 45 client-owned dogs diagnosed with severe AKI, receiving 48 CRRT treatments at a veterinary teaching hospital. PROCEDURES Retrospective study. Search of medical records of dogs with AKI managed by CRRT. RESULTS Median serum urea and creatinine at CRRT initiation were 252 mg/dL [Inter quartile range (IQR), 148 mg/dL; range, 64 to 603 mg/dL] and 9.0 mg/dL (IQR, 7 mg/dL; range, 4.3 to 42.2 mg/dL), respectively. Median treatment duration was 21 hours (IQR, 8.8 hours; range, 3 to 32 hours). Systemic heparinization and regional citrate anticoagulation were used in 24 treatments each (50%). The prescribed median CRRT dose for the entire treatment was 1 mL/kg/min (IQR, 0.4 mL/kg/min; range, 0.3 to 2.5 mL/kg/min). The median hourly URR was 4% (IQR, 1%; range, 2% to 12%), overall URR was 76% (IQR, 30%; range, 11% to 92%) and median Kt/V was 2.34 (IQR, 1.9; range, 0.24 to 7.02). The CRRT dose was increased gradually from 0.9 mL/kg/min to 1.4 mL/kg/min (P < .001) and the hourly URR decreased from 6.5% to 5.5% (P = .05). The main complication was clotting of the extra-corporeal circuit, occurring in 6/48 treatments (13%). Twenty-four dogs (53%) survived to discharge. CLINICAL RELEVANCE CRRT is safe when the prescription is based on the current veterinary guidelines for gradual urea reduction. Treatment efficacy can be maximized by gradually increasing the dose according to the actual URR.

Abstract
OBJECTIVE To compare the short- and long-term outcomes of dogs and cats with left-sided congestive heart failure (L-CHF) undergoing positive pressure ventilation (PPV) to patients undergoing PPV for other causes and to determine risk factors associated with outcomes in this population. DESIGN This retrospective study included dogs and cats that underwent PPV during 2018-2020. The study group included patients diagnosed with L-CHF. The control group included patients who were ventilated for reasons other than L-CHF. The risk factors evaluated included vital signs on presentation, ventilator settings, development of azotemia during hospitalization, cardiopulmonary resuscitation (CPR), complications, and medications used. SETTING University Teaching Hospital. ANIMALS Fifty (32 dogs, 18 cats) study group animals and 51 (39 dogs, 12 cats) control group animals were included in the L-CHF and control groups, respectively. MEASUREMENTS AND MAIN RESULTS Sixty-six percent (33/50) of L-CHF patients, compared with 35% (18/51) of the control patients, were weaned off PPV (P = 0.002). Fifty-four percent (27/50) of the L-CHF patients survived to discharge, compared with 26% (13/51) of the control group patients (P = 0.003). However, only 54% (12/22) of the discharged L-CHF patients survived for >2 months compared to 100% of the control patients. The median survival time for dogs and cats with L-CHF surviving to discharge was 240 days (range: 1-730 days). In dogs, factors negatively associated with survival included CPR in both groups and the development of azotemia in the L-CHF group. Anemia on presentation was negatively associated with survival for both cats and dogs in the control group. CONCLUSIONS Dogs and cats undergoing PPV due to L-CHF were more commonly weaned off the ventilator and survived to discharge compared to other causes necessitating PPV. However, these patients suffer from severe heart disease, and therefore, their long-term survival is guaranteed.

Abstract
BACKGROUND Organophosphates and carbamates are important sources of intoxication for humans and animals. However, large-scale studies of these intoxications in cats are unavailable. METHODS The medical records of 39 cats presented to a veterinary teaching hospital with acute organophosphate or carbamate intoxication were reviewed retrospectively. RESULTS Mortality in intoxicated cats was 15%. Low respiratory rate and low rectal temperature at presentation were associated with death. Other common clinical signs included weakness, ataxia, apathy, recumbency, anorexia and bradycardia, but these were unassociated with the outcome. The common biochemical abnormalities included decreased serum butyryl-choline esterase activity, acidaemia, hypercarbaemia and total hypocalcaemia, and increased creatine kinase activity and total plasma protein concentration. There were no significant differences in haematological, biochemical and blood gas analytes between survivors and non-survivors. Common medications and treatments included 2-pyridine aldoxime methyl-chloride-pralidoxime (2-PAM) (74%), metoclopramide (64%), antibiotics (64%), diphenhydramine (59%) and atropine sulphate (54%). There were no significant drug and treatment differences between survivors and non-survivors. The secondary complications of the intoxication included pneumonia (10%), acute kidney injury (10%) and pancreatitis (8%). CONCLUSIONS Acute cholinergic crisis due to organophosphate or carbamate intoxication has a fair prognosis in cats. Low respiratory rate and low rectal temperature at presentation were associated with death. The most commonly used specific medications in this study included 2-PAM, diphenhydramine and atropine sulphate.

Abstract
OBJECTIVE To describe the successful treatment of a life-threatening type III hypersensitivity reaction suspected to have been related to human serum albumin (HSA) administration in a dog with therapeutic plasma exchange (TPE). CASE SUMMARY A 3-year-old neutered male mixed breed dog was suspected to have developed immune-mediated vasculitis 2 weeks after the administration of HSA (740 mg/kg) for the management of hypoalbuminemia resulting from septic peritonitis. The dog was presented with fever, edema, hypoalbuminemia (26 g/L [2.6 g/dL]; reference interval, 30-44 g/L [3.0-4.4 g/dL]), and coagulopathy. The dog was treated with fresh frozen plasma (FFP) and glucocorticoids but remained hypoalbuminemic (18 g/L [1.8 g/dL]) and developed acute kidney injury (AKI). Over 4 days, 3 TPE treatments were performed, with a total of 2.7 plasma volumes exchanged. Replacement fluids consisted of a combination of FFP, hydroxyethyl starch 6%, and 0.9% saline solution. Following TPE treatments, serum albumin concentration increased (from 18 g/L [1.8 g/dL] to 25 g/L [2.5 g/dL]), serum creatinine concentration decreased (from 340 μmol/L [3.9 mg/dL] to 87 μmol/L [0.98 mg/dL]), and clotting times normalized (activated partial thromboplastin time decreased from 33 seconds to 14.5 seconds). There was a gradual but consistent clinical improvement of the edema and overall demeanor of the dog. No significant adverse effects were noted during the TPE treatments, and the dog was discharged after 8 days of hospitalization. Following discharge, the dog had complete clinical resolution of edema and AKI. NEW/UNIQUE INFORMATION: This is the first report describing successful use of TPE for the management of an immune-mediated reaction (type III hypersensitivity) following HSA administration.

Abstract
OBJECTIVES Bite wounds are a common cause of trauma in cats; nevertheless, large-scale studies of this trauma in cats are lacking. The aims of the present study were to characterise the clinical and clinicopathological findings in these cats, to assess the association of these variables and therapeutic measures with survival, and to assess the association between the animal trauma triage (ATT) score and severity of injuries score (SS) at presentation with survival. METHODS The medical records of cats presented to a veterinary teaching hospital and two large referral clinics were reviewed retrospectively. RESULTS The study included 72 cats diagnosed with canine bite wounds (with the dog attacks having been witnessed). Seventy-one percent of cats suffered multiple injuries, and there was a significant association between the number of injured body areas and survival, and between severity of injury and survival (P = 0.02 and P = 0.012, respectively). The median ATT scores and SSs for non-survivors were significantly higher compared with survivors (P <0.0001). There was a strong and significant correlation between ATT scores and SSs (r = 0.704, P <0.0001). Total protein and albumin were significantly lower and alanine aminotransferase significantly higher in non-survivors compared with survivors (P ⩽0.032). Fifty percent of cats were treated conservatively, 32% by local surgical debridement and 18% of cats required an exploratory procedure. Cats undergoing more aggressive treatments were significantly less likely to survive (P = 0.029). Fifty-seven cats (79%) survived to discharge. CONCLUSIONS AND RELEVANCE Cats sustaining canine bite wounds have a good overall prognosis for survival to discharge. High ATT score, high SS, multiple body area injuries, penetrating injuries, radiographic evidence of vertebral body fractures and body wall abnormalities, as well as hypoproteinaemia and elevated alanine aminotransferase, are negative predictors of survival.

Abstract
OBJECTIVES The aims of this study were to evaluate associations between abnormal head CT findings and outcome, and to examine the prognostic value of the Koret CT score (KCTS) in cats sustaining acute traumatic brain injury (TBI). METHODS The medical records of cats hospitalised with TBI that underwent head CT scans within 72 h of admission were retrospectively reviewed. CT scans were evaluated independently by a radiologist and a neurologist who were blinded to the outcome. A KCTS and modified Glasgow Coma Scale (MGCS) were assigned to each cat and the association between abnormal CT findings, KCTS, MGCS and outcome were analysed. RESULTS Fourteen cats were included in the study: nine (64.2%) survivors and five (35.7%) non-survivors. Of the nine cats that were discharged, one was a short-term survivor (10 days) and eight (57.1%) were long-term survivors (⩾6 months). Abnormal CT findings included lateral ventricle asymmetry/midline shift (42.8%), intracranial haemorrhage (35.7%), caudotentorial lesions (14.2%) and cranial vault fractures (14.2%), all of which were depressed. Intracranial haemorrhage was found to be significantly and negatively associated with short-term (P = 0.005) and long-term (P = 0.023) survival. KCTS was significantly associated with short-term survival (P = 0.002) and long-term survival (P = 0.004). A KCTS cut-off value of 2 yielded a 100% sensitivity and 100% specificity for short-term survival and 100% sensitivity and 80% specificity for long-term survival. A MGCS cut-off value of ⩾13 was associated with a 100% sensitivity and 100% specificity for short-term survival, and with a 100% sensitivity and 80% specificity for long-term survival. CONCLUSIONS AND RELEVANCE KCTS, performed up to 72 h from injury, can be used as an additional diagnostic tool for the prediction of survival in cats with TBI.

Abstract
CONTEXT Echis coloratus is endemic to the Middle East. Clinical reports describing E. coloratus envenomation in humans are scarce, while natural envenomations of animals were not reported. Such envenomations may induce systemic coagulopathy. This report describes a confirmed E. coloratus envenomation in a dog, with assessment of the global hemostasis by thromboelastometry. CASE DETAILS A 6-year old Belgian Shepherd dog was presented in shock, mucosal bleeding and swelling due to snakebite. Laboratory tests showed prolonged prothrombin and activated partial thromboplastin times. Because Daboia palaestinae is the most common venomous snake in Israel, immunoglobulin-G monovalent D. palaestinae antivenom was administered, with supportive care. The dog improved clinically, was discharged, and was readmitted, with active bleeding from the bite site. The dead snake was only then identified as E. coloratus. Thromboelastometry demonstrated severe hypocoagulability. The dog was treated with polyvalent antivenom directed against venoms of several Middle Eastern snakes, fresh-frozen plasma and packed red blood cells. Bleeding completely ceased, and thromboelastometry results improved. The dog was discharged. 3 days later, all hemostatic test results had normalized. DISCUSSION Thromboelastometry is useful for assessing the hemostatic status in E. coloratus envenomation, and for monitoring and managing the venom-induced coagulopathy, and guide plasma and polyvalent antivenom treatment.

Abstract
Traumatic brain injury (TBI) is a common condition in veterinary medicine with relatively high mortality rate. Recently, a study that correlated abnormal computed tomography (CT) findings with outcome in dogs with head trauma established a prognostic scoring system termed Koret CT score (KCTS). The purpose of this study was to evaluate the accuracy of the KCTS in making short- and long-term prognosis in dogs presented within 72 h of TBI. Thirty-five dogs that were admitted to a hospital during 2010-2019 with TBI and were CT-scanned within 72 h of injury were included in the study. Retrospectively collected data included signalment, modified Glasgow Coma Scale score (MGCS), CT findings, and outcome, i.e. short-term (defined as 10 days) and long-term (6 months) survival. CT images were reviewed and the KCTS was calculated for all dogs. Association between KCTS and outcome was examined. A significant negative association was found between KCTS and both short- and long-term survival. The area under receiver operating characteristic curve for KCTS for short- and long-term survival was 0.9 and 0.87, respectively. Furthermore, the probability of survival in the short term was predicated by the KCTS in an almost linear fashion and a score of 3 points or less on the KCTS was associated with survival with 85% sensitivity and 100% specificity. These results validate the prognostic value of the KCTS in dogs with TBI and provide a complementary tool for serial clinical and neurological evaluation.

Abstract
Extended-spectrum β-lactamase-producing Enterobacterales (ESBL-PE) gut shedding in human medicine is considered as a major reservoir for ESBL-associated infections in high risk patients. In veterinary medicine, data regarding ESBL-PE gut shedding on admission to emergency and critical care department is scarce. We aimed to determine ESBL-PE shedding rates by dogs and cats in this setting and to determine the risk factors for shedding, at two separate periods, three-years apart. Rectal swabs were collected from animals, on admission and 72 h post admission, enriched and plated on Chromagar ESBL plates, followed by bacterial identification. ESBL phenotype was confirmed and antibiotic susceptibility profiles were determined (Vitek 2). Medical records were reviewed for risk factor analysis (SPSS). Overall, 248 animals were sampled, including 108 animals on period I (2015-2016) and 140 animals on period II (2019). In both periods combined, 21.4% of animals shed ESBL-PE on admission, and shedding rates increased significantly during hospitalization (53.7%, p-value < 0.001). The main ESBL-PE species were Escherichia coli and Klebsiella pneumoniae, accounting for more than 85% of the isolates. In a multivariable analysis, previous hospitalization was a risk factor for ESBL-PE gut shedding (p-value = 0.01, Odds ratio = 3.05, 95% Confidence interval 1.28-7.27). Our findings demonstrate significant ESBL-PE gut shedding among small animals in the emergency and critical care department, posing the necessity to design and implement control measures to prevent transmission and optimize antibiotic therapy in this setting.

Abstract
The ability to make an accurate prognosis, which is a prerequisite for treatment decisions, is very limited in dogs with traumatic brain injury (TBI). To determine whether serum concentrations of neuron-specific enolase (NSE) have prognostic value in dogs following TBI, we conducted a prospective, observational, controlled clinical study in an intensive care unit of a university teaching hospital. The study population comprised 24 dogs admitted to the hospital within 72 h of a known event of TBI between January 2010 and January 2015, as well as 25 control healthy shelter dogs admitted for elective neutering. Seventeen injured dogs (70%) survived to discharge, four were euthanized and three died within 48 h. Serum samples were obtained from all dogs (in injured dogs, within 72 h of TBI) and NSE concentrations were measured using enzyme-linked immonosorbent assay. Associations between NSE levels and outcome, Modified Glasgow Coma Scale, time to sampling, age or haemolysis scale were determined. Mean serum NSE concentrations were decreased in dogs with TBI compared with healthy controls (19.4 ± 4.14 ng/ml vs. 24.9 ± 4.6 ng/ml, P <0.001). No association was found between serum NSE concentrations and either survival or severity of neurological impairment. A negative correlation was found between serum NSE concentrations and time from trauma to blood collection (r = -0.50, P = 0.022). These results indicate that serum NSE concentration in dogs following TBI is not an effective marker for severity or outcome. Further studies are warranted to standardize serum NSE measurements in dogs and to determine the peak and half-life levels of this potential biomarker.

Abstract
OBJECTIVE To describe the successful management of ventricular fibrillation (VF) and ventricular tachycardia (VT) using cardiopulmonary resuscitation, including defibrillation, followed by continuous rate infusion of IV amiodarone, in a cat with cardiac arrest secondary to tachyarrhythmia. CASE SUMMARY A 12-year-old previously healthy neutered male Scottish Fold cat presented following an acute episode of collapse. Initial physical examination revealed severe tachycardia and cardiovascular collapse. Within a few minutes after arrival, the cat experienced cardiopulmonary arrest. Electrocardiographic assessment was suggestive of VF, and CPR was initiated, including 2 rounds of defibrillation (2 joule/kg each), resulting in return of spontaneous circulation with sustained VT. After procainamide and lidocaine failed to result in conversion to normal sinus rhythm (NSR), continuous IV amiodarone therapy was initiated, and NSR was achieved. Echocardiography demonstrated severe systolic dysfunction, and tachycardia-induced cardiomyopathy (TICM) secondary to chronic VT was suspected; however, dilated cardiomyopathy (DCM) or end-stage hypertrophic cardiomyopathy could not be ruled out. The patient was discharged the following day with oral amiodarone and pimobendan. During a recheck examination performed 7 months later the cat was in NSR, with no direct evidence of long-term amiodarone adverse effects. The cat died acutely at home 8 months after discharge. NEW OR UNIQUE INFORMATION PROVIDED This report is the first to describe the successful use of IV amiodarone in a cat to manage sustained VT following CPR.

Abstract
Organophosphates (OP) and carbamates are commonly used insecticides and important intoxication sources of humans and animals. Nevertheless, large scale studies of these intoxications in dogs are unavailable. The medical records of dogs presented to a veterinary hospital were reviewed retrospectively. The study included 102 dogs definitely diagnosed with acute OP or carbamate intoxication. The most common presenting clinical signs included muscle tremor, hypersalivation, miosis, weakness, vomiting and diarrhea. Hypersalivation, muscle tremor and tachypnea were significantly (P < 0.05) associated with survival to discharge; while weakness, mental dullness, anorexia, pale mucous membranes and paddling were significantly associated with death. Common laboratory abnormalities included decreased butyrylcholine esterase activity, acidemia, increased total plasma protein, leukocytosis, hypochloridemia, hyperbilirubinemia, increased creatinine and alanine transaminase (ALT), aspartate transaminase (AST) and creatine kinase activities, and prolonged activated partial thromboplastin time (aPTT). Compared to the survivors, the non-survivors showed significantly: higher frequencies of thrombocytopenia, hypocarbemia, prolonged prothrombin time (PT), hypernatremia, hyperkalemia, hypocholesterolemia, hypoproteinemia, hypertriglyceridemia, increased ALT activity and increased urea concentration; lower median concentrations of venous blood bicarbonate, serum chloride and total CO2; and higher medians of PT, serum total bilirubin and urea concentrations, and ALT and AST activities. Intoxicated dogs were commonly treated with diphenhydramine, atropine-sulfate, antibiotics, diazepam and pralidoxime, while some (19.2%) required general anesthesia and mechanical ventilation. The survival rate of dogs treated by gastric lavage was higher (P = 0.041) compared to that of the remaining dogs. Development of respiratory failure and mechanical ventilation requirement were significantly associated (P < 0.001) with death. The mortality rate was 17%.

Abstract
OBJECTIVE To report the use of gas chromatography-mass spectrometry to confirm a diagnosis of synthetic cannabis toxicosis in a dog and to describe the clinical course of the intoxication. CASE SUMMARY An 11-year-old neutered female Boxer dog was referred due to acute onset of vomiting, ataxia, dull mentation, and delirium that progressed to generalized seizures, unresponsive to diazepam. Prior to presentation, the dog was found lying down, minimally responsive with vomitus around it. A chewed bag containing dried plant material was found next to the dog. The dog was anesthetized and ventilated with positive pressure for 16 hours, and eventually made a full recovery. Gas chromatography-mass spectrometry analysis of the plant material and a plasma sample from the dog revealed presence of the synthetic cannabinoid N-[(1S)-1-(aminocarbonyl)-2-methylpropyl]-1-(cyclohexylmethyl)-1H-indazole-3-carboxamide, also known as AB-CHMINACA, a relatively new illegal synthetic cannabinoid, known by the local forensic police department as a drug of recreational abuse. NEW OR UNIQUE INFORMATION PROVIDED Reports of synthetic cannabinoid toxicosis in dogs are scarce and are based on urine test kits for tetrahydrocannabinol that have not been validated in the veterinary literature. This is the first report to describe utilization of gas chromatography-mass spectrometry on canine plasma to reach a definitive diagnosis.

Abstract
Coagulopathies in horses are common and potentially life-threatening. In equine field medicine, a portable point-of-care (POC) prothrombin time (PT) testing device could be useful to identify early changes in extrinsic clotting. The CoaguChek-XS (Roche Diagnostics) is a small, portable POC PT analyzer used in human medicine. Our preliminary study assessed the suitability of CoaguChek-XS for testing PT in horses and established the PT reference interval (PT RI) in healthy horses using this instrument. Blood samples collected from 102 healthy and ill horses were analyzed with the CoaguChek-XS and compared to a semi-automated coagulometric analyzer (SACA) as the gold standard. There was a significant positive correlation between the 2 measurement methods ( r = 0.765, p < 0.01), and very good agreement, with 97% of the samples falling within limits of agreement. The mean CoaguChek-XS PT coefficient of variation was 0.8%, indicating high precision. With high precision and good agreement with the coagulometric PT, the CoaguChek-XS should be further validated for PT measurement in horses.

Abstract
Gastric dilatation and volvulus (GDV) is a life-threatening condition, suspected to result in differential tissue perfusion in different regions of the body. Lactate is a biomarker of hypoperfusion that correlates with treatment outcomes in dogs with GDV. This prospective observational study aimed to compare lactate between saphenous and cephalic venous samples in 45 client-owned dogs with GDV, to evaluate their association with treatment outcomes (survival, surgical complications, and duration of hospitalization) and to assess the correlation between lactate and other biochemical parameters. Both saphenous and cephalic lactate concentrations were significantly higher in non-survivors (P = 0.01). No statistical difference was found between lactate concentrations in saphenous versus cephalic venous samples (P = 0.480). For each dog, the difference in lactate between saphenous and cephalic veins was calculated (Δlactate = saphenous - cephalic); it was not associated with survival (P = 0.198), surgical complications (P = 0.346), or duration of hospitalization (P = 0.803). Higher lactate and lower glucose (saphenous vein) were associated with lower PCV and higher creatinine, on presentation. The results of this study failed to show an association between Δlactate concentrations and treatment outcomes in dogs with GDV; however, in agreement with previous studies, lower lactate was associated with a decreased mortality rate.

Abstract
The aim of this study was to determine whether the addition of constant rate infusion (CRI) to intermittent intravenous bolus (IVB) administration of furosemide resulted in an improvement in medical outcomes in dogs and cats with acute left-sided congestive heart failure (L-CHF). A total of 76 client-owned dogs and 24 client-owned cats admitted with acute L-CHF were retrospectively divided between an IVB group (43 dogs and 16 cats) and a CRI group (33 dogs and 8 cats). The median furosemide dose used in dogs in the CRI group (median 0.99mg/kg/h; range 0.025-3.73mg/kg/h) was lower than the dose used in dogs in the IVB group (median 1.19mg/kg/h; range 0.027-7.14mg/kg/h; P=0.008). Respiratory rates were lower in the IVB group (P=0.005) and the CRI group (P=0.039) compared to pre-treatment values. The overall short-term mortality was 15%. A trend of longer hospitalisation in the IVB group relative to the CRI group (P=0.07) was shown. Creatinine and total plasma protein concentrations increased more in the CRI group than in the IVB group, suggestive of a higher risk of dehydration and azotaemia. There may be safety profile differences between CRI and IVB, warranting a prospective study using a larger sample size.

Abstract
OBJECTIVE To characterize clinical and laboratory findings in cats with naturally occurring sepsis, emphasizing hemostasis-related findings, and evaluate these variables for associations with patient outcomes. DESIGN Prospective, observational, clinical study. ANIMALS 31 cats with sepsis and 33 healthy control cats. PROCEDURES Data collected included history; clinical signs; results of hematologic, serum biochemical, and hemostatic tests; diagnosis; and outcome (survival vs death during hospitalization or ≤ 30 days after hospital discharge). Differences between cats with and without sepsis and associations between variables of interest and death were analyzed statistically. RESULTS The sepsis group included cats with pyothorax (n = 10), septic peritonitis (7), panleukopenia virus infection (5), bite wounds (5), abscesses and diffuse cellulitis (3), and pyometra (1). Common clinical abnormalities included dehydration (21 cats), lethargy (21), anorexia (18), pale mucous membranes (15), and dullness (15). Numerous clinicopathologic abnormalities were identified in cats with sepsis; novel findings included metarubricytosis, hypertriglyceridemia, and high circulating muscle enzyme activities. Median activated partial thromboplastin time and plasma D-dimer concentrations were significantly higher, and total protein C and antithrombin activities were significantly lower, in the sepsis group than in healthy control cats. Disseminated intravascular coagulopathy was uncommon (4/22 [18%] cats with sepsis). None of the clinicopathologic abnormalities were significantly associated with death on multivariate analysis. CONCLUSIONS AND CLINICAL RELEVANCE Cats with sepsis had multiple hematologic, biochemical, and hemostatic abnormalities on hospital admission, including several findings suggestive of hemostatic derangement. Additional research including larger numbers of cats is needed to further investigate these findings and explore associations with outcome.

Abstract
This study has retrospectively reviewed the medical records of 140 dogs sustaining road traffic accident (RTA), and has examined the population characteristics, medical history, injury type, physical examination, emergency laboratory tests and radiography findings, the animal trauma triage (ATT) score, the length of hospitalisation, the complications and the outcome. The survival rate was 83.2 per cent. Younger dogs sustained more frequently lung contusions and limb fractures, while larger dogs more frequently suffered limb fractures, and smaller dogs and older ones sustained more frequently pelvic fractures and sacroiliac luxation (P<0.05 for all). Dogs sustaining orthopaedic injuries required longer hospitalisation (P<0.001). The survival rates of non-ambulatory dogs (P<0.001) and those with neurological abnormalities (P<0.001), abnormal body temperature (P=0.001), hyperglycaemia (P=0.026) or hypoproteinaemia (P=0.04) at presentation were lower compared with those in which these were absent. The number of injured body systems was significantly (P<0.001) and positively associated with death. Dogs surviving RTA to presentation to the hospital have a good prognosis for survival to discharge. Older age, and high ATT score, abnormal body temperature, neurological deficits, hyperglycaemia and hypoproteinaemia at presentation, and occurrence of multiorgan trauma are negative prognostic indicators in such dogs.

Abstract
This study assessed the global hemostasis (including prothrombin time [PT], activated partial thromboplastin time [aPTT], antithrombin activity [ATA], fibrinogen and d-Dimer concentrations, platelet count, plateletcrit and thromboelastometry) in healthy pregnant bitches, comparing the results with those of healthy bitches at different estrous cycle stages, and assessed whether hemostatic changes during pregnancy are associated with serum progesterone concentration or the presence of fetuses in utero. The results show that pregnant bitches have higher fibrinogen concentration, platelet count and platelatecrit, and that fibrin and global clot formations occur faster than in non-pregnant bitches at different estrous cycle stages. Additionally, clot strength was higher in pregnant bitches than in non-pregnant ones. There were no differences in PT, ATA, and D-dimer concentration between all study groups. The aPTT was significantly shorter in bitches at the fourth and last pregnancy weeks, compared to the anestrus group, and shorter in both the fourth and last pregnancy weeks groups, compared to diestrus group. These results all support a hypercoagulable state in healthy pregnant bitches, unassociated with progesterone concentration.

Abstract
OBJECTIVE To investigate hemostatic analyte abnormalities and their association with mortality in dogs with naturally occurring heatstroke. DESIGN Prospective observational study. SETTING University teaching hospital. ANIMALS Thirty client-owned dogs with naturally occurring heatstroke. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Citrated and EDTA blood samples were collected at presentation and at 4, 12, 24, 36, and 48 hours postpresentation (PP). Hemostatic tests performed included platelet count, prothrombin and activated partial thromboplastin times (PT and aPTT, respectively), antithrombin activity (ATA), total protein C activity (tPCA), fibrinogen, and D-dimer concentrations. The overall survival rate was 60% (18/30 dogs). Older age, higher heart rate and rectal temperature at presentation, and time from onset of clinical signs to presentation were significantly associated with mortality. Hemostatic analytes at presentation were not associated with mortality. Prolonged PT and aPTT at 12-24 hours PP, lower tPCA at 12 hours PP, and hypofibrinogenemia at 24 hours PP were significantly (P < 0.05) associated with mortality. Increased D-dimer concentration and low ATA were common at all time points, but were not associated with mortality. The frequency of disseminated intravascular coagulation (DIC) increased in nonsurvivors throughout hospitalization, but the development of DIC was not associated with mortality. The number of abnormal coagulation disturbances during the first 24 hours was significantly higher in nonsurvivors (P = 0.04). CONCLUSIONS Hemostatic derangements are common in dogs with naturally occurring heatstroke. Alterations in PT, aPTT, tPCA, and fibrinogen concentrations appear to be associated with the outcome at 12-24 hours PP, exemplifying the need for serial measurement of multiple laboratory hemostatic tests during hospitalization, even when within reference interval on presentation. The development of DIC, as defined in this cohort, was not associated with mortality; however, nonsurvivors had significantly more coagulation abnormalities during the first 24 hours PP.

Abstract
OBJECTIVE To describe the use of an ultrasound-guided intracardiac xenotransfusion of canine packed red blood cells (pRBC) to the left ventricle of a severely anemic cat during cardiopulmonary resuscitation (CPR). CASE SUMMARY An 8-year-old previously healthy neutered female cat was presented with severe weakness after she had disappeared for 1 month. On presentation, the cat was in hypovolemic shock, laterally recumbent, and severely anemic with massive flea infestation. Within minutes of admission, the cat became agonal and suffered cardiopulmonary arrest. CPR was immediately initiated; however, attempts to gain IV access during CPR were unsuccessful. As the cat's blood type was yet unknown, 10 mL of canine pRBC was transfused directly into the left ventricular chamber using ultrasound guidance, as well as 0.02 mg/kg of epinephrine using a similar technique. The cat regained cardiac activity and once the jugular vein was cannulated it received 20 additional mL of canine pRBC intravenously. The packed cell volume and total plasma protein following the intracardiac transfusion were 0.09 L/L [9%] and 30 g/L [3.0 g/dL], respectively. Subsequent blood typing revealed the cat had type B blood. The cat was discharged 3 days post-CPR and was alive and doing well 3 months following discharge. NEW OR UNIQUE INFORMATION PROVIDED This is the first reported case of ultrasound-guided intracardiac canine-to-feline xenotransfusion during CPR.

Abstract
Heatstroke is a serious illness in dogs characterized by core temperatures above 41°C with central nervous system dysfunction. Experimental heatstroke models have tried to correlate biomarker levels with the severity of the syndrome. Serum heat shock protein (eHSP70) levels were recently evaluated as a biomarker of heat tolerance and acclimation, their role as a marker of heatstroke is inconclusive. Here, we monitored eHSP70 levels in correlation with systemic biomarkers in 30 naturally occurring canine heatstroke cases. Thirty dogs diagnosed with environmental (33%) or exertional (66%) heatstroke admitted to hospital (0-14 h post-injury) were tested for biomarkers of organ damage and coagulation parameters. eHSP70 levels were measured upon admission and 4, 12, and 24 h later (T1, T2, and T3, respectively). No differences were found between exertional and environmental heatstroke cases. The eHSP profile demonstrated an inverted bell shape, with the lowest levels at the 12 h time point. A positive correlation between eHSP70, lactate, and aPPT was also noted at T2 in all the dogs in the study. Twenty-four h after presentation, eHSP70 levels returned to those measured upon admission, this change was only significant in the survivors. The obtained results suggest that eHSP72 level profile may be predictive of survival.

Abstract
The aim of this study was to develop a minimally invasive thyroarytenoid lateralization technique (MITAL). Eleven unilateral MITAL procedures were performed on 11 canine cadavers. Two hypodermic needles were passed through the skin into the lumen of the larynx, penetrating the thyroid and arytenoid cartilages. Suture material was passed through the needles to lateralize the arytenoid cartilage. A rigid endoscope was used to visualize needle insertion and suture material placement. A key-hole approach to the larynx was performed and the suture material was knotted on the lateral aspect of the thyroid cartilage. The change in the rima glottidis area was recorded as were the duration of the procedure and complications encountered. The landmarks for needle insertion were easily palpated, and a significant increase in the area of the rima glottidis was documented after performing unilateral MITAL. In conclusion, unilateral MITAL is a quick, minimally invasive procedure which increases the area of the rima glottidis in cadaveric dogs.

Abstract
OBJECTIVE To assess the effects of tranexamic acid (TA) on hematological, hemostatic, and thromboelastographic analytes in healthy adult dogs. DESIGN Prospective study. SETTING University teaching hospital. ANIMALS Eleven healthy, staff-owned, adult dogs. MEASUREMENTS AND MAIN RESULTS Dogs were administered TA as an IV bolus, followed by a 3-hour constant rate infusion (CRI). Complete blood count, prothrombin time, activated partial thromboplastin time, D-dimer, antithrombin, fibrinogen, and thromboelastography (TEG) were measured prior to, and immediately after TA administration. Vomiting occurred transiently in the first 2 treated dogs, immediately after 20 and 15 mg/kg IV boluses, but not during the CRI. In all other dogs the TA IV bolus dose was reduced to 10 mg/kg, and administered slower, and vomiting did not occur. All measured hemostatic and hematological analytes remained within their reference intervals, however, following TA treatment, significant decreases were recorded in prothrombin time, TEG R and A30 values, Hct, and hemoglobin concentration, while the TEG LY30 significantly increased. CONCLUSIONS Administration of TA as a slow IV bolus at 10 mg/kg, followed by a 10 mg/kg/h CRI over 3 hours to healthy dogs is safe; however, its effect on TEG A30, A60, LY30, and LY60 values was inconsistent with its expected anti-fibrinolytic properties.

Abstract
OBJECTIVE To describe the clinical course, outcome and success rate of 8 dogs with persistent pneumothorax treated with autologous blood-patch pleurodesis (ABP). DESIGN Retrospective case series. SETTING University teaching hospital ANIMALS Eight client-owned dogs. INTERVENTION Non-coagulated blood was aseptically collected from the jugular vein and injected immediately into the pleural cavity of dogs with persistent pneumothorax. MEASUREMENTS AND MAIN RESULTS The procedure was successful in 7 of 8 dogs. The median duration of pneumothorax until the ABP was performed was 4 days (range 2-6 days). Pneumothorax resolved immediately after 1 treatment in 4 dogs. Pleurodesis was repeated once in 3 dogs, and twice in 1 case after which it resolved in 3 of the 4 dogs. Out of a total of 13 ABP procedures performed in 8 dogs, 5 (62.5%) were successful after 1 procedure and the success rate increased to 87.5% after additional procedures. One dog failed ABP and was euthanized 3 days later due to continued deterioration and a hospital acquired pneumonia. Mild to moderate complications occurred in 2 other dogs and resolved in both. CONCLUSIONS ABP is a simple, inexpensive, and relatively safe procedure which can be considered in dogs with persistent pneumothorax that have failed conservative or surgical management. Infections following ABP were documented in 2 of the 8 dogs and resolved in 1 dog.

Abstract
The objective of the study was to review the veterinary literature for evidence-based and common clinical practice supporting the postoperative management of dogs with gastric dilatation and volvulus (GDV). GDV involves rapid accumulation of gas in the stomach, gastric volvulus, increased intragastric pressure, and decreased venous return. GDV is characterized by relative hypovolemic-distributive and cardiogenic shock, during which the whole body may be subjected to inadequate tissue perfusion and ischemia. Intensive postoperative management of the patients with GDV is essential for survival. Therapy in the postoperative period is focused on maintaining tissue perfusion along with intensive monitoring for prevention and early identification of ischemia-reperfusion injury (IRI) and consequent potential complications such as hypotension, cardiac arrhythmias, acute kidney injury (AKI), gastric ulceration, electrolyte imbalances, and pain. In addition, early identification of patients in need for re-exploration owing to gastric necrosis, abdominal sepsis, or splenic thrombosis is crucial. Therapy with intravenous lidocaine may play a central role in combating IRI and cardiac arrhythmias. The most serious complications of GDV are associated with IRI and consequent systemic inflammatory response syndrome and multiple organ dysfunction syndrome. Other reported complications include hypotension, AKI, disseminated intravascular coagulation, gastric ulceration, and cardiac arrhythmias. Despite appropriate medical and surgical treatment, the reported mortality rate in dogs with GDV is high (10%-28%). Dogs with GDV that are affected with gastric necrosis or develop AKI have higher mortality rates.

Abstract
Background Acute limb paralysis because of arterial thromboembolism (ATE) occurs in cats and less commonly in dogs. ATE is diagnosed based on physical examination findings and, occasionally, advanced imaging. Hypothesis/Objectives Peripheral, affected limb venous glucose concentration is decreased in ATE, whereas its systemic concentration is within or above reference interval. Animals Client‐owned cats and dogs were divided into 3 respective groups: acute limb paralysis because of ATE (22 cats and 9 dogs); acute limb paralysis secondary to orthopedic or neurologic conditions (nonambulatory controls; 10 cats and 11 dogs); ambulatory animals presented because of various diseases (ambulatory controls; 10 cats and 9 dogs). Methods Prospective observational, clinical study. Systemic and local (affected limb) blood glucose concentrations were measured. Their absolute and relative differences (ΔGlu and %ΔGlu, respectively) were compared among groups. Results ΔGlu and %ΔGlu were significantly higher in the ATE cats and dogs groups, compared to both of their respective controls (P < .0001 and P < .001, respectively). No significant differences were observed between the control groups. Receiver operator characteristics analysis of ΔGlu and %ΔGlu as predictors of ATE had area under the curve of 0.96 and 0.99 in cats, respectively, and 1.00 and 1.00, in dogs, respectively. ΔGlu cutoffs of 30 mg/dL and 16 mg/dL, in cats and dogs, respectively, corresponded to sensitivity and specificity of 100% and 90% in cats, respectively, and 100% in dogs. Conclusions and Clinical Importance ΔGlu and %ΔGlu are accurate, readily available, diagnostic markers of acute ATE in paralyzed cats and dogs.

Abstract
OBJECTIVES To assess the performance of a portable prothrombin time (PT) analyzer (CoaguChek-XS) in dogs. ANIMALS Ninety-seven dogs composed of 20 healthy dogs, 45 ill dogs, and 32 ill dogs with altered coagulation. PROCEDURES Samples were concurrently obtained and PT was measured using the CoaguChek-XS and an automated coagulation analyzer. Agreement between methods was assessed using Spearman's correlation and Bland-Altman analysis. RESULTS The reference interval for PT using the CoaguChek-XS was 9.6-11.5 s. The CoaguChek-XS was easy to use, required a small volume of whole blood, and gave results within 1 min. The mean difference in PT between the 2 methods was 2.58 s (SD 3.10), and 94% of the samples fell within limits of agreement. The correlation was moderate, but significant (r = 0.35, P < 0.001). Sensitivity and specificity of the CoaguCheck-XS PT compared to analyzer PT were 92% and 56%, respectively, and increased to 95% and 77% on intent to treat basis. The coefficient of variance was 0.72%. The CoaguChek-XS identified all 8 dogs with anticoagulant rodenticide intoxication, although a discrepancy was noted from the analyzer results. In anemic dogs (PCV≤25%), the CoaguChek-XS did not display accurate results. CONCLUSIONS The CoaguChek-XS is a simple, user-friendly, highly precise PT analyzer. Results had moderate correlation and good agreement with a standard method. It can be used reliably for screening dogs when the PT is normal. However, when the CoaguChek-XS PT is prolonged or when the PCV is ≤25%, results should be confirmed using a standard method.

Abstract
The objective of this study was to assess the frequency of gait abnormalities and lameness (GAL) in bitches with pyometra, and their association with clinical and laboratory findings. The study included 79 bitches diagnosed with pyometra and 35 negative control intact bitches presented with other soft tissue surgical disorders. Dogs with a history of chronic lameness due to orthopaedic or neurological origin were excluded. A history of GAL was more frequent in the pyometra group (47 per cent) compared with the control group (20 per cent) (P=0.007). In the pyometra group, bitches presenting GAL had (P<0.04) higher frequencies of closed-cervix pyometra, anorexia and vomiting, as well as higher serum creatinine concentration and muscle enzymes activity, compared with those in without GAL. GAL signs resolved postovariohysterectomy in all but one bitch. The results suggest that GAL signs occur frequently in bitches with pyometra, especially in closed-cervix disease. Therefore, pyometra should be considered among the differential diagnoses when GAL occurs, especially when the clinical signs are non-specific and the reproductive history is unclear.

Abstract
Military working dogs in hot countries undergo exercise training at high ambient temperatures for at least 9 mo annually. Physiological adaptations to these harsh conditions have been extensively studied; however, studies focusing on the underlying molecular adaptations are limited. In the current study, military working dogs were chosen as a model to examine the effects of superimposing endurance exercise on seasonal acclimatization to environmental heat stress. The lymphocyte HSP70 profile and extracellular HSP70 were studied in tandem with physiological performance in the dogs from their recruitment for the following 2 yr. Aerobic power and heat shock proteins were measured at the end of each summer, with physical performance tests (PPTs) in an acclimatized room (22°C). The study shows that together with a profound enhancement of aerobic power and physical performance, hsp72 mRNA induction immediately post-PPT and 45 min later, progressively increased throughout the study period (relative change in median lymphocyte hsp72 mRNA first PPT, 4.22 and 12.82; second PPT, 17.19 and 109.05, respectively), whereas induction of HSP72 protein was stable. These responses suggest that cellular/molecular adaptive tools for maintaining HSP72 homeostasis exist. There was also a significant rise in basal and peak median optical density extracellular HSP at the end of each exercise test (first PPT, 0.13 and 0.15; second PPT, 1.04 and 1.52, respectively). The relationship between these enhancements and improved aerobic power capacity is not yet fully understood.

OBJECTIVE To examine if the tension at the site of a urethral anastomosis can be relieved by performing either a crural release technique or an ischial osteotomy technique. STUDY DESIGN Cadaveric study and 2 case reports. ANIMALS Adult male cat cadavers (n = 18). METHODS Cats were divided into 2 groups; crural release (n = 9) and ischial osteotomy (n = 9). In each group, 20%, 25%, and 30% of the pelvic urethra was excised in 3 cats. The length of the urethral defect was measured after excision of the urethral segment, and after approximation, before and subsequent to the tension relieving technique performed. Two clinical cases are described. RESULTS Both crural release and ischial osteotomy were effective in relieving the tension encountered at the urethral anastomosis after removal of 20% of the urethral length. In the ischial osteotomy group, apposition without tension after removing up to 30% of the intrapelvic urethral length was easily achieved. A similar technique was successfully used in 2 clinical cases. CONCLUSION Crural release and ischial osteotomy techniques allow approximation and tension free anastomosis of large segmental defects of the pelvic urethra in cats.

Abstract
OBJECTIVE To assess the efficacy of IV lidocaine in decreasing complication rate and improving the outcome in dogs with gastric dilatation volvulus (GDV). DESIGN Prospective non-controlled study of 83 lidocaine-treated dogs with GDV compared to 47 untreated historical controls with GDV. SETTING University veterinary teaching hospital. ANIMALS One hundred and thirty client-owned dogs with naturally occurring GDV. INTERVENTIONS Study group dogs were treated at presentation with lidocaine (2 mg/kg, IV bolus) followed by constant rate infusion (CRI) of 0.05 mg/kg/min for 24 h. Historical control dogs did not receive any lidocaine. MEASUREMENTS AND MAIN RESULTS There were no group differences in age, body weight, time lag from onset of clinical signs to presentation, rectal temperature and pulse rate at presentation, and proportion of gastric wall necrosis. The proportions of cardiac arrhythmias and acute kidney injury (AKI) were significantly (P< 0.001 and P = 0.045, respectively) lower in the lidocaine group (10/83 [12%] versus 18/47 [38.3%] and 3/83 [3.6] versus 0/47). Median hospitalization time period was shorter (P = 0.05) in the lidocaine group compared to the controls (median 48 h; range 24-360 h versus median 72 h; range 24-144 h, respectively). CONCLUSION AND CLINICAL RELEVANCE Early treatment with IV lidocaine bolus, followed by CRI of lidocaine for 24 h post presentation decreased the occurrence of cardiac arrhythmias, AKI and hospitalization time period significantly in lidocaine-treated dogs with GDV compared to untreated historical controls. Due to the nonblinded, placebo-uncontrolled, nonrandomized nature of the current study, further evaluation of the efficacy of lidocaine in dogs with GDV is warranted.

Abstract
Acute respiratory distress syndrome (ARDS) was diagnosed in 2 dogs with acute dyspnea. Short-term positive pressure ventilation and intense critical and nursing care were provided. Both dogs improved and were discharged. Few reports describe successful recovery from ARDS. Due to advances in positive pressure ventilation and improvement in the supportive care of critically ill veterinary patients, the prognosis for ARDS may improve.

Abstract
CASE DESCRIPTION A 15-kg (33-lb) pregnant female mixed-breed dog of unknown age was referred because of a 10-day history of difficulty breathing. CLINICAL FINDINGS Physical examination findings were dyspnea, tachypnea, decreased bronchovesicular sounds (bilateral), muffled heart sounds, and abdominal distention with palpable fetuses. Hematologic abnormalities included anemia, leukocytosis, and thrombocytosis. Abnormalities detected during serum biochemical analysis included decreases in concentrations of albumin, sodium, triglycerides, and total calcium and increases in activities of alkaline phosphatase, alanine aminotransferase, gamma-glutamyltransferase, aspartate aminotransferase, lactate dehydrogenase, and creatine kinase. Thoracic radiography revealed a diaphragmatic hernia with fetuses and a soft tissue or fluid opacity within the thoracic cavity. TREATMENT AND OUTCOME Exploratory celiotomy, ovariohysterectomy, partial sternotomy, placement of a right-sided thoracostomy tube, and herniorrhaphy were performed. After surgery, pneumothorax developed, and the thoracostomy tube was used to remove pleural effusion and free air. The pneumothorax did not resolve after continuous drainage of the thoracic cavity for 4 days. Autologous blood pleurodesis was performed by infusion of 80 mL (6 mL/kg [2.73 mL/lb]) of whole blood. The pneumothorax resolved immediately after injection of the blood. CONCLUSIONS AND CLINICAL RELEVANCE Blood pleurodesis was used for resolution of pneumothorax in a dog after correction of a diaphragmatic hernia. Blood pleurodesis may provide a simple, safe, and inexpensive medical treatment for resolution of persistent (duration>5 days) pneumothorax when surgery is not an option.

Abstract
OBJECTIVE To determine agreement between arterial partial pressures of carbon dioxide (PaCO(2)) and end-tidal partial pressures of carbon dioxide (PETCO(2)) measured with a nasal catheter in spontaneously breathing, critically ill dogs. DESIGN Validation study. ANIMALS 26 client-owned dogs admitted to an intensive care unit for various conditions. PROCEDURES PaCO(2) was measured with a commercial blood gas analyzer, and PETCO(2) was measured with a sidestream capnograph attached to a nasal catheter. Measurements were obtained twice (ie, with and without supplemental oxygen). Paired values were compared by means of the Pearson correlation method. Level of agreement was assessed by means of the Bland-Altman method. RESULTS Mean difference between PaCO(2) and PETCO(2) when dogs did not receive supplemental oxygen (mean +/- SD, 3.95 +/- 4.92 mm Hg) was significantly lower than mean difference when dogs did receive supplemental oxygen (6.87 +/- 6.42 mm Hg). Mean difference in dogs with a condition affecting the respiratory system (8.55 +/- 5.43 mm Hg) was significantly higher than mean difference in dogs without respiratory tract disease (3.28 +/- 3.23 mm Hg). There was a significant linear correlation and good agreement between measured values of PaCO(2) and PETCO(2). Catheter size, ventilatory status, and outcome were not significantly associated with mean difference between PaCO(2) and PETCO(2). CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that nasal capnography is a clinically relevant method of estimating PaCO(2) in spontaneously breathing, critically ill dogs, but that values should be interpreted with caution in dogs receiving supplemental oxygen and in dogs with conditions affecting the respiratory system.

Abstract
A 13-year-old, intact male, golden retriever was presented for glossomegaly. A diagnosis of a caudal lingual abscess was made by fine needle aspiration under general anesthesia. The dog showed marked clinical improvement following abscess drainage. Lingual abscesses should be included as a differential diagnosis in any dog with an unexplained acute glossomegaly.
