Euthanasia

Question Answer
What is euthanasia?The act of inducing humane death in an animal
What are the requirements for euthanasia?Free of stress and pain, rapid loss of consciousness, practical, safe
What is the process of euthanasia?Loss of consciousness, cardiac or respiratory arrest, loss of cerebral function
Which animals can inhalants be used?<7kg
What is a disadvantage to using inhalants?Seizures are common
What are advantages to using CO2?Rapid, cheap, readily available, minimal risk to personnel, no toxic accumulation in body.
What are disadvantages to using CO2?Nasal mucosal irritant, some species may have a stress response, not effective for diggers/divers/neonates
If using chemical injection what must be done with care?Body disposal. Can't be in the food chain, remains risk to other animals eating them.
What are disadvantages to using barbiturates?Needs IV injection, drugs are controlled, may have an excitatory phase, terminal gasp
When can a intrasplenic barbiturate injection be used?If the animal is uncosious/anesthetized and the owner did not want to observe.

Can KCl be used on conscious animals for euthanasia?No. not FDA approved.
What kind of drugs are in T61?Anesthetic, muscle relaxant, and a local anesthetic
What are disadvantages to T61 use?IV only, controlled, slow injection necessary, trained personnel
What should be considered when determining a euthanasia method?Presence of owners, species and size of animal, personnel, skills and equipment
Most common euthanasia protocol for dogs?Acepromazine, ketamine, pentobarbital
