(eg. description of the frequency and severity of the symptoms
On 25 Feb 2015, the clinic's staff contacted the company call center regarding dyspnea, impaired consciousness and drooling in a dog following accidental ingestion of an unknown quantity of thiamethoxam (worst case scenario dose: 1.1 mg/kg). A verbal history was obtained. The dog was not a regular patient at the clinic where it was presented. On 22 Feb 2015, the owner had found the dog eating thiamethoxam fly bait in the room where the product was stored with other farm products which may have also included warfarin. 72 hours post ingestion, the patient started to present breathing difficulty. The sign worsened overnight and the owner took the dog to the clinic where it was hospitalized and treated with intravenous fluids (IV fluids) and an injection of dexamethasone. A radiograph of the chest was unremarkable. The signs improved for a period of time but worsened again. The dog was having more and more difficulty to breathe (coded as respiratory distress) and became cyanotic. It was euthanized for humane reason. UPDATE 11 Mar 2015 The clinic staff confirmed that the owner declined necropsy. The clinic was also informed that per the safety data for this product, the dose ingested by the patient was very unlikely to cause the reported signs.
Major
Assessment: Timing possible. Not fitting pharmacodynamics but fitting for signs reported in the literature with this class of pesticide (neonicotinoid) at toxic levels. Not fitting pharmacodynamics in this dog considering the estimated maximum dose ingested and known safety data in dogs and LD50 in rats. Health status of patient prior to incident is unknown. Possible ingestion of other pesticide is confounding. Without necropsy, this case is unassessable. (O)
