Awesome video. Just to clarify, 4-MP is the treatment of choice for cats... but it must be used within 3 hours. Studies (Connelly et al) have shown that it is MORE effective than ethanol (with less side effects). So definitely use it in cats! :)

Thanks for the update Dr. Lee, I haven't had the opportunity to use 4MP on a cat yet (which is good for the cats of Portland!). Anyone else have the chance to use it in cats? It's currently on back order so everyone is getting the alcohol...

Thank you so much for this video. A few colleges and I watched this on a slow ER night and it was very helpful!

I enjoyed this video very much. I think it will be very helpful. I think it would be good to update the rodenticide toxicity to include the non-anticoagulant products, now that this is occurring more often.

Looked at the slide again. It is on there. I just thought that it had listed 1st then 2nd class anti-coagulants. Maybe make it "non anti-coagulants" instead of "Bromethalin" since there are others as well and they are growing in popularity.

Great video! I saw a CE on Toxicology by a veterinary toxicologist and they mentioned that it is best practice to always tube charcoal to the stomach?

Hi! Thanks for viewing the video. Activated charcoal is a pain in the rear end to administer, that's for certain! In order to get the full recommended dose (which is usually HIGHER than what is written on the label of the medication) and to ensure least risk of aspiration, it is best to tube feed the charcoal. Best practice is to intubate the patient and then pass a feeding tube into the stomach, confirm placement with a radiograph, then administer the charcoal. Of course that involves placing an IV catheter, using an injectable anesthetic, intubating and monitoring the brief anesthetic procedure. In reality, people may opt to pass a small bore (8Fr) feeding tube in a sedated, unintubated patient and once radiograph confirms placement of the tube in the stomach then administer the charcoal. I am always hesitant to do this because as long as the patient is sedated there is a risk of regurgitation and aspiration. There are not many pets that would allow passage of an orogastric tube without some sort of sedation. This is why if the patient is compliant and mentally appropriate you may try to syringe feed the charcoal. Some dogs are silly enough to even eat the charcoal if it's mixed with a little food! There was an interesting study from JVECC 2013; 23(3):263-7, that examined how food mixed with activated charcoal affects the adsorption ability of charcoal. The authors concluded the presence of food only slightly decrease the efficacy of activated charcoal in eliminating acetaminophen and therefore said it was a reasonable strategy for getting activated charcoal into a patient. I hope this answers you question!
