SPECIFIC TOXINS -

• Some of the more common toxicities seen at the
  AEC !
• ( phone 24/7 -- 253 474-0791 ! )

17

• A sugar substitute found in many chewing gums and
  sugar free candies. It may be purchased in powder
  form for baking.
• It effects dogs much differently than humans and
  causes large amounts of insulin to be released
• Most common symptom seen is profound hypoglycemia
  but hepatic injury has been noted at high dose
  ingestions

18
Treatment

• Baseline blood glucose
• Full chemistry if a large amount has been
  ingested
• Emesis
• Check BGs frequently
• Intravenous fluid support with or without
  dextrose may be indicated if symptoms of
  hypoglycemia are shown
• More aggressive treatments may be needed if signs
  of liver damage are determined

19

• Three-step progression
• 30min-12hrs after ingestion neurological
  symptoms including ataxia, confusion,
  inappropriate mentation, vomiting, and/or general
  malaise
• 12hr-24hrs after ingestion tachycardia,
  hypertension, tachypnea, and metabolic acidosis
• 24hr-72hrs after ingestion formation of calcium
  oxalate crystals in the kidneys thus resulting in
  acute renal failure

20

• Woods Lamp of vomitus or urine
• Microscopic evaluation of urine for crystals
• Needle-like calcium oxalate crystals
• Ethylene Glycol Test Kit
• Kacey Ethylene Glycol Test Strips

21
Treatment

• Decontamination by means of emesis or gastric
  Lavage
• Intravenous Fluid Diuresis to correct electrolyte
  imbalances and metabolic acidosis
• 20 Ethyl Alcohol intravenous solution or
  Antizol administration
• Hemodialysis

22

• Commonly used analgesic in humans (sometimes used
  in dogs with codeine for arthritis relief)
• Metobolization occurs largely in the liver
• Symptoms in dogs can be vague including vomiting,
  diarrhea, tachycardia, and/or tachypnea. If
  methemoglobinemia is present, icterus, abdominal
  pain, and swelling of the face/paws may be
  observed.
• In cats, symptoms usually are a result of
  hemolysis resulting in anemia. Unusual /
  characteristic change to cat MM color.

23

• Diagnosis relies heavily on client history
• Emesis induction (if consumption occurred within
  the four hour window)
• Activated Charcoal administration
• N-acetylcysteine therapy
• Includes loading dose followed by five to seven
  tapering doses
• Liver Values should be closely monitored for
  48hrs

24

• An alkaloid found in cocoa and chocolate
• Higher concentrations in dark and bakers
  chocolate
• Used in the medical field in the form of
  Theophylline as an adenosine antagonist
• Symptomsmild /moderate gastrointestinal
  disruption, muscle tremors, tachycardia,
  hyperactivity, seizures, coma

Toxic Doses
25
Treatment

• Emesis
• Activated Charcoal
• Gastric Lavage
• Sedation
• Intravenous Fluid Diuresis
• Urinary Catheter/ Frequent Walks
• Cardiac Blood Pressure Monitoring

26

• Sold in the form of over the counter flea control
  indicated for dogs
• Most commonly affects cats
• Tremorgenic Effects (not to be confused with
  seizures)
• Easily recognized affliction

27
Treatment

• Intravenous Methocarbamol (Robaxin)
• Bathe w/ Dawn dish soap
• Intravenous Fluid support
• Thermoregulation

28

• SLUD (salivation, lacrimation, urination,
  defecation)
• Mushrooms
• most common culprit is the Amanita mushroom
• Tremoring and/or muscle spasm
• Liver injury/failure can be a result of untreated
  ingestion
• Molluscicides
• Main offensive ingredient Metaldehyde
• rapid onset of neurological symptoms that begin 1
  to 4 hours after exposure
• Compost/Trash Consumption
• Tremorgenic mycotoxins in mold

29

• Emesis
• Brown, blue, or green granules, mushrooms, trash,
  food wrappers, etc
• Gastric Lavage
• Activated Charcoal w/ Sorbitol
• Anticonvulsants/ Muscle Relaxants
• Thermoregulation
• Intravenous Fluid Support
• Gastrointestinal Protectants
• sucralfate, famotidine, etc

30

• Two main subdivisions
• Anticoagulants Generations I and II
• brodifacoum, coumatetralyl, and wafarin, fumarin,
  chlorophacinone, diphacinone, pindone,
  bromadiolone
• Neurodegenerative Agents
• Bromethalin
• Mechanism of Action
• Anticoagulant rodenticides block the enzymes
  K1-2, 3-epoxide-reductase and K1-quinone-reductase
  depriving the animal of Vitamin K
• Neurodegenerative rodenticides uncouple
  oxidativephosphorylation in the mitochondria of
  the central nervous system decreasing the
  production of ATP thus resulting in buildup of
  cerebral spinal fluid and vacuolization of myelin
• Prognosis differs largely between the two

31

• Wide range of symptoms may be observed
• pale mucous membranes, generalized weakness,
  coughing, epistaxis, hematuria, hematochezia,
  hemorrhagic diarrhea, distended abdomen, rapid
  subcutaneous mass development, lameness with
  swollen joint(s), or collapse depending on the
  site where the bleeding is occurring
• Elevated , activated clotting time (ACT),
  prothrombin (PT) and activated partial
  thromboplastin (PTT) clotting times

32
Treatment

• Emesis
• Gastric Lavage
• Only if early ingestion!!
• Activated Charcoal
• Vitamin K administration
• Initial dose may be given subcutaneously,
  followed by a 3wk course of oral supplementation
• Fresh Frozen Plasma
• Intravenous Fluid Support
• Whole Blood or Packed Red Blood Cells may also be
  indicated

33

• Owner Compliance
• Specified patient use only
• Legible Instructions
• When, why, how much?
• Route of administration
• Refrigeration
• Potential Side Effects
• Index of safety
• Laboratory analysis
• Follow up

34

• Non-steroidal Anti Inflammatory Drugs
• carprofen, etodolac, meloxicam, deracoxib,
  tepoxalin, firocoxib
• Most common side effects include vomiting,
  diarrhea, gastric ulcers, kidney and/or liver
  damage
• Antibiotics
• metronidazole, amoxicillin, doxycycline,
  cephalexin, enrofloxacin,
• Most common side effects are vomiting and
  diarrhea
• metronidazole toxicity effects the brain and
  equilibrium signs may present as ataxia,
  nystagmus, seizures

35

• Emesis if acute ingestion
• Activated Charcoal
• Gastric Lavage
• Intravenous Fluid Diuresis
• Gastrointestinal protectants
• ie sucralfate, famotidine, cimetidine, pepcid,
  etc
• Frequent monitoring of kidney and liver enzymes

36

• By far the most important treatment that you can
  provide to any patient who has ingested a toxin
  is DECONTAMINATION
• Veterinary technicians are a valuable resource to
  any veterinary hospital and can make a huge
  difference in the life of the patients you care
  for.
