Objective – To describe the management and outcome of a dog presenting with intractable seizures associated with traumatic brain injury. Case Summary – A spayed female Wheaten Terrier was presented to an emergency clinic with neurologic deficits (modified Glasgow coma scale of 10) shortly after a road traffic accident. Seizures were uncontrolled despite aggressive pharmacologic intervention. Controlled hypothermia to achieve a rectal temperature of 33–35°C (91.4–95°F) was initiated as a protective measure to reduce intracranial pressure and cerebral metabolic rate, and to assist with seizure control. Intubation and mechanical ventilation were required to protect the airway and manage hypercapnia associated with hypoventilation. The patient went on to make a full recovery, although behavioral changes were noted by the owners for an 8‐week period following injury. New or Unique Information Provided – To the author's knowledge, this is the first instance of therapeutic hypothermia reported in the veterinary literature. A short review of this treatment modality is provided.  相似文献

Objective – To describe a case of Dieffenbachia ingestion in a dog presented for dysphagia and airway obstruction successfully treated with a temporary tracheostomy and supportive care beyond that reported in the veterinary literature. Case Summary – An 8‐year‐old male neutered Labrador Retriever, weighing 30 kg, was presented with the complaint of choking and gagging. Abdominal radiographs showed that he had a distended stomach full of foreign material and a gastrotomy was performed. After receiving preanesthetic medication, the dog developed inspiratory stridor and during anesthetic induction, marked oropharyngeal swelling complicated tracheal intubation. During surgery a large amount of dog bedding and Dieffenbachia plant material was removed. Because of the severity of the oropharyngeal swelling, the dog required a temporary tracheostomy and treatment for an acute allergic reaction related to the Dieffenbachia ingestion. The patient was discharged after 6 days in the hospital and had no significant complications. New or Unique Information Provided – To our knowledge, this is the first reported case of successful treatment of an airway obstruction related to the toxicity of Dieffenbachia ingestion.  相似文献

Objective – To describe a rare, but potential clinical manifestation of phenazopyridine (PAP) toxicity in a dog. Case Summary – A 6‐year‐old spayed female Chihuahua was evaluated for ataxia and dysphagia after ingestion of 200 mg (66 mg/kg) of PAP hydrochloride. The dog was presented to the hospital with shifting leg lameness involving all 4 limbs, which progressed to reluctance to walk and severe diffuse muscle hyperesthesia. Clinical laboratory abnormalities included marked increases in serum alanine aminotransferase, aspartate aminotransferase, creatine kinase, mild increases in alkaline phosphatase, and increased c‐Tnl‐troponin concentration. Treatment included administration of intravenous fluids, muscle relaxants, pain medications, and hepatoprotectants for 5 days in the hospital, and medical management at home for an additional 5 days. Follow‐up examinations performed 1 and 6 months after initial presentation revealed the dog to be clinically healthy with serum biochemical profiles within reference intervals. New or Unique Information Provided – The purpose of this report is to describe an unusual manifestation of PAP toxicosis in a dog, which has not been previously reported in the literature. A review of the ASPCA Animal Poison Control Center database revealed 347 cases of PAP exposure in dogs during 2000–2009 underscoring the importance of being aware of this toxicity in the dog.  相似文献

Objective: To describe a case of SOMA intoxication in a dog. Case summary: A 13‐year‐old, 25 kg, female spayed Australian shepherd presented to the emergency service after ingestion of ten to fifteen 350 mg tablets of SOMA (carisoprodol), a muscle relaxant used for back pain in humans. Toxic effects of the drug in this dog included mild sinus tachycardia, respiratory depression, seizures, and ataxia. The dog's mentation progressively deteriorated from depressed to comatose within 1 hour after admission. Treatment on initial presentation consisted of induction of emesis while the dog still had a gag reflex, administration of activated charcoal, oxygen therapy, and supportive care. The dog was discharged to the owner prior to full recovery (4 days later). New or unique information provided: This is the first known report of carisoprodol intoxication in the dog.  相似文献

Objective: To describe the clinical consequences following ingestion by a dog of a moxidectin‐containing equine deworming product. Few reports exist concerning the treatment and outcome of severe moxidectin toxicity. Treatment, known factors influencing intoxication, and prognosis are reviewed. Case summary: A 10‐month‐old female Border Collie ingested an unknown quantity of a moxidectin‐containing equine deworming product several hours before presentation. Severe neurological signs subsequently developed and included: ataxia, seizures, coma, and respiratory failure. The dog was treated with supportive care including intravenous fluids, activated charcoal, and positive pressure ventilation. Normal spontaneous respiration returned in 34 hours and the patient was discharged 58 hours after ingestion. Full recovery occurred within 1 week of intoxication. New information provided: This report describes moxidectin intoxication and associated respiratory failure in a dog that required mechanical ventilation. The dog's recovery was rapid. Despite severity of signs, the prognosis for patients with moxidectin intoxication is good with appropriate supportive care.  相似文献

Objective – To describe the successful surgical management of a brain abscess in a dog secondary to bite wound. Case Summary – A 10‐year‐old neutered female Welsh Corgi/Chihuahua, weighing 5.3 kg, was presented for evaluation of seizures, ataxia, and falling to the left 8 days after a presumptive fight with another dog. On examination at presentation, the dog was alert, responsive, and ambulatory with tetra‐ataxia, falling to the left, left‐sided postural deficits, and absent left menace response. Within 24 hours, the dog progressed to nonambulatory tetraparesis with minimal motor, absent postural reactions of all limbs, left nasal hypalgesia, reduced gag reflex, and depressed mentation. Computed tomographic images of the brain were suggestive of a bite wound fracture of the right parietal bone with secondary meningoencephalitis, right parietal lobe abscessation, and white matter edema adjacent to the bone fracture. A modified right rostrotentorial craniectomy was performed, the abscess was identified, contents of the abscess were removed, and the surgical site was flushed extensively before closing. Corynebacterium spp. was cultured from within the abscess. Within hours of surgery, the dog was quiet but alert, responsive, and sitting up in her cage. In addition to surgical intervention, intensive care, broad‐spectrum IV antimicrobials, and supportive therapy led to significant neurologic improvement with only occasional seizures and mild postural reaction deficits of the left hindlimb remaining. New or Unique Information Provided – Abscess formation within the CNS is uncommon in dogs and cats and is associated with a high mortality rate. In veterinary medicine the management of brain abscesses is controversial with limited information available regarding treatment. This is the first case report that demonstrates surgical intervention in combination with antimicrobial therapy can be used successfully in the treatment of a canine brain abscess.  相似文献

Objective – To describe a case of gastrointestinal tract perforation, septic peritonitis and coagulopathy caused by ingestion of multiple magnets in a dog. Case Summary – An 8‐month‐old castrated male Rottweiler, weighing 30.5 kg was presented for evaluation of vomiting and weakness. Abdominal radiography and abdominal ultrasonographic examination identified a metallic foreign object within the gastric lumen, presence of free peritoneal gas, and peritoneal effusion. Septic peritonitis was diagnosed by abdominal fluid analysis. Exploratory celiotomy revealed the presence of an omental abscess, and gastric and colonic perforations. Four magnetic foreign objects were found within the lumen of the perforated stomach. Surgical management including removal of the magnets, abscess debridement and excision, perforation repair, and abdominal drainage combined with intensive medical therapy resulted in complete recovery of this dog. New or Unique Information Provided – This report describes in detail the case management of a dog that developed both gastric and colonic perforations and severe morbidity secondary to ingesting multiple magnets.  相似文献

Objective – To describe the successful treatment of accidental ethanol intoxication with hemodialysis in a dog. Case Summary – A 1.5‐year‐old female intact mixed breed dog was presented in a comatose state believed to be due to ethanol intoxication. The initial 9 hours of supportive care treatment were complicated by multiple seizures and hypothermia, and resulted in only minimal improvement in the dog's level of consciousness. Hemodialysis was implemented and resulted in rapid clinical recovery, corresponding to a rapid decline in serum ethanol concentration. New or Unique Information Provided – To the authors' knowledge, this is the first reported case of using hemodialysis to treat accidental ethanol intoxication in a dog. The patient's initial serum ethanol concentration was higher than those previously reported for cases of accidental ethanol intoxication in dogs, and the serum ethanol concentration was shown to rapidly decline during hemodialysis. Treatment with hemodialysis for severe ethanol intoxication was effective in this case and may be able to decrease morbidity and mortality in some cases.  相似文献

A 5-month-old 22-kg (48.4-lb) sexually intact male Collie was examined after ingesting a moxidectin-containing deworming medication. The dog was comatose and had respiratory arrest after progressively worsening lethargy, ataxia, and seizures. Exposure was confirmed by isolation of moxidectin from a biopsy specimen of adipose tissue, using liquid chromatography-mass spectroscopy methods. Treatment included use of intermittent positive-pressure ventilation, activated charcoal and cathartic administered enterally, nutrients administered via nasogastric tube, and intensive supportive care. The dog was weaned from a ventilator on day 6 after ingestion and was discharged on day 10. The dog was considered clinically normal during examination 24 days after ingestion. On the basis of the dog reported here and toxicologic data provided by the manufacturer of the deworming product, some Collies may have increased susceptibility to products containing high doses of moxidectin.  相似文献

Objective: To describe the medical and nutritional management of a 4‐year‐old Weimaraner with acute hepatic failure and immune‐mediated hemolytic anemia (IMHA) associated with consuming a commercial dog food. Case summary: A 4‐year‐old male castrated Weimaraner developed signs of IMHA, hepatic failure, disseminated intravascular coagulopathy, and malnutrition after consuming a commercial dog food. During the course of hospitalization, medical management included immunosuppressive therapy and supportive care. Nutritional support consisted of both enteral and parenteral nutrition. The dog was discharged after 19 days of hospitalization and fully recovered by 6 months. An investigation by the Food and Drug Administration was not able to determine the exact cause of the acute hepatic failure and IMHA. New information provided: This is the first case report documenting the medical and nutritional management of a critically ill animal associated with ingestion of this commercial dog food.  相似文献

Objective: To describe a case of xylitol intoxication causing fulminant hepatic failure in a dog. Case summary: A 2.5‐year‐old castrated male English Springer Spaniel weighing 26 kg, was presented after ingestion of half of a loaf of bread containing the sweetener xylitol. Toxic effects of the xylitol in this dog included vomiting, mild hypoglycemia and fulminant hepatic failure. Clinical management of acute hepatic failure and subsequent coagulopathy with supportive care and fresh frozen plasma is described. The dog was discharged 3 days after admission after a full clinical recovery. New or unique information provided: This paper describes the clinical consequence and successful treatment of fulminant hepatic failure in a dog following ingestion of xylitol.  相似文献

Objective: To report successful treatment of severe salt intoxication and hypernatremia in a dog. Case summary: A 5‐year‐old intact female Doberman Pinscher was admitted to the intensive care unit with a history of seizures and coma. The owner had administered approximately 100 g of cooking salt to induce vomiting following ingestion of a nontoxic dose (10 g) of chocolate. Upon admission, the dog was comatose with intermittent seizures and vomiting. Diagnostic tests confirmed salt intoxication (Na: 200 mEq/L, Cl: 180 mEq/L) and metabolic acidosis (pH: 7.18; pCO2: 39 mmHg; HCO3: 14.3 mmol/L). Immediate treatment included intravenous fluid therapy, an anticonvulsant, antiemetic, diuretic, low molecular weight heparin, and supplemental oxygen. A fluid therapy protocol was initiated to decrease serum sodium concentration by approximately 2 mEq/L/hr. After 24 hours of intensive care, the patient regained consciousness and volume and acid‐base abnormalities improved. The patient developed a variety of abnormal clinical signs as a result of the severe hypernatremia. After 5 days of treatment, the serum sodium concentration returned to the established reference range. The patient recovered completely in 10 days. New information provided: Severe hypernatremia due to salt ingestion is a rare condition in dogs. All dogs in previous case reports of salt intoxication have died. This case report is the first to report survival of a dog with severe salt intoxication.  相似文献

Objective – To describe the use of continuous electroencephalographic (EEG) monitoring for management of status epilepticus (SE) in dogs and cats. Design – Retrospective study. Setting – University teaching hospital. Animals – Ten patients (7 dogs, 3 cats) with SE of differing etiology (idiopathic epilepsy, n=3; toxicity, n=4; meningoencephalitis, n=2; undefined, n=1). Interventions – The EEG was recorded continuously from 5 stainless‐steel needle electrodes inserted SC. Animals were treated with diazepam and phenobarbital followed by either propofol (n=3) or pentobarbital (n=7) as a continuous rate of infusion. Measurements and Main Results – Clinical seizures stopped after induction of anesthesia in each animal. The EEG, however, still showed distinct epileptiform patterns (spikes, polyspikes) in all animals. Paroxysms were suppressed by increasing the infusion rate of either pentobarbital or propofol. A burst‐suppression pattern was achieved in 5 animals. EEG epileptiform activity reappeared in 4 animals when attempting to taper the dose after >6 hours of anesthesia. This was interpreted as ongoing EEG seizure activity and an increased risk for clinical seizures, and the anesthetic dosage was adjusted accordingly. Conclusion – Continuous EEG monitoring appears to be a useful tool for therapeutic monitoring of SE in dogs and cats. It allows the detection of EEG seizures without the appearance of clinical seizures. Further investigations with blinded investigators and homogeneous animal groups to define therapeutic endpoints are warranted.  相似文献

A 1-year-old intact male Boxer was presented to the Texas Veterinary Medical Center for emergency treatment following suspected ingestion of a large number of tablets of Adderall, a pharmaceutical amphetamine. The dog had a temperature of 41.7 degrees C, heart rate of 192 beats per minute, and a respiratory rate of 100 breaths per minute. The dog was anxious and agitated with bilaterally dilated pupils, and shortly thereafter became recumbent and incontinent. Initial CBC results included mild leukopenia and mild thrombocytopenia. The dog was not anemic (HCT 39.9%) and had only slight polychromasia, but had 48 nucleated RBCs/100 WBC (7500/microL). Moderate numbers of neutrophils had hypersegmented nuclei and several pyknotic cells were noted. The metarubricytosis persisted for approximately 56 hours while hypersegmentation and pyknotic cells were no longer found at 8 hours after presentation. The dog received supportive care and recovered uneventfully. We hypothesized that hyperpyrexia associated with Adderall toxicity resulted in inappropriate metarubricytosis due to damaged bone marrow endothelium, and resulted in hypersegmentation and pyknosis due to damaged or accelerated aging of neutrophils in peripheral blood. Metarubricytosis has been reported previously in dogs with heat-induced illness, such as heat stroke.  相似文献

Objective – To compare the incidence of seizures in dogs with intervertebral disk disease after iopamidol or iomeprol myelography, and to assess whether the incidence of seizures differed between the 2 agents when severity of neurological deficits, location of cord compression, duration of anesthesia, site of myelogram, volume of contrast, and concentration of contrast were evaluated. Design – Retrospective study. Setting – Veterinary teaching hospital. Animals – One hundred and sixty‐one client‐owned dogs with intervertebral disk disease. Interventions – Subarachnoid injection of contrast medium. Measurements and Main Results – One hundred and sixty‐one dogs with intervertebral disk disease were subjected to myelography using iopamidol (n=74) or iomeprol (n=87). Cranial myelography was performed in 31 dogs, caudal myelography in 125 and both cranial and caudal myelography in 5. Seizures occurred in 23 of 161 (14%) dogs. There was no significant difference overall between iopamidol and iomeprol myelography. However, in dogs with thoracolumbar disk extrusion and paraplegia, seizures occurred more frequently after caudal myelography using iopamidol compared with iomeprol. Conclusions – Both iomeprol and iopamidol are suitable for myelography in dogs. Iomeprol is recommended for caudal myelography in paraplegic dogs with thoracolumbar disk extrusion due to the higher incidence of seizures in this group when iopamidol was used.  相似文献

Objective– To describe the clinical manifestations and treatment of Rauwolfia serpentina toxicity in a dog. Case Summary– A 9‐month‐old intact male mixed breed dog was presented following ingestion of an antihypertensive medication containing alkaloids from R. serpentina. R. serpentina alkaloids cause depletion of the biologic amines: norepinephrine, dopamine, and serotonin. The dog experienced hypotension, mental depression, bradycardia, diarrhea, bronchoconstriction, and gastrointestinal ulceration similar to the adverse effects reported in humans. The dog was released from the hospital after 4 days of supportive care. New Information Provided– This is the first case of accidental R. serpentina toxicity in a dog reported in the literature. This case had a good clinical outcome with supportive care and monitoring of all the subsequent adverse effects.  相似文献

A 5.5-year-old French bulldog was presented with acute neck pain and a short history of central vestibular syndrome. A marked neutrophilic pleocytosis and numerous gram-positive cocci were evident on cerebrospinal fluid (CSF) cytology. Streptococcus pneumoniae, a pathogen of humans, was isolated upon CSF microbiological culture. Treatment consisted of intravenous antibiotics, supportive care, and anticonvulsants for the generalized seizures which developed shortly after admission. The dog responded to therapy and two years later exhibited only a mild, residual head tilt. The pathogenesis and treatment of bacterial meningoencephalitis in dogs are reviewed.  相似文献

Objective – To determine the safety and efficacy of high‐dose fomepizole compared with ethanol (EtOH) in cats with ethylene glycol (EG) toxicosis. Design – Prospective study. Setting – University veterinary research laboratory. Animals – Thirteen cats. Interventions – Two cats received injections of high‐dose fomepizole (Study 1). Three cats received lethal doses of EG and fomepizole treatment was initiated 1, 2, or 3 hours later (Study 2). Eight cats received a lethal dose of EG and were treated with fomepizole or EtOH (Study 3). Cats treated with fomepizole received 125 mg/kg IV initially, then 31.25 mg/kg at 12, 24, and 36 hours. Cats treated with EtOH received 5 mL of 20% EtOH/kg IV initially, then every 6 hours for 5 treatments, then every 8 hours for 4 treatments. Cats also received fluids and supportive therapy as needed. Measurements and Main Results – Clinical signs were monitored and serial blood analyses performed. Cats receiving fomepizole experienced mild sedation but no biochemical evidence of toxicity. Cats receiving fomepizole for EG intoxication survived if therapy was initiated within 3 hours of EG ingestion. One of the 6 developed acute renal failure (ARF) but survived. Only 1 of the 3 cats treated with EtOH 3 hours following EG ingestion survived; 2 developed ARF and were euthanized. Cats treated 4 hours following EG ingestion developed ARF, whether treated with EtOH or fomepizole. Conclusions – Fomepizole is safe when administered to cats in high doses, prevents EG‐induced fatal ARF when therapy is instituted within 3 hours of EG ingestion, and is more effective than treatment with EtOH.  相似文献
