Sedation of Animals Prior to Euthanasia • Wherever possible, animals are sedated prior to euthanasia (exceptions – perinatal pups and kittens, birds, pinkie rats and mice) • This minimizes the stress of the procedure to the animals and the staff carrying out the procedure
Sedating Cats • WHAT? • - equal volumes of Zoletil (Zolazepam 50 mg/ml and Tiletamine 50 mg/ml) and Hypnovel(Midazolam 5 mg/ml) • HOW? • - subcutaneously • HOW MUCH?
ADVANTAGES • - no restricted drugs needed (compared with xylazine/ketamine sedation) • - can be give subcutaneously (no painful intramuscular injections) • - gives full anaesthesia with recovery possible (in most cases – old/sick cats) • - maintains blood pressure • - rapid onset of action (approx 5 mins) • - Hypnovel minimizes disorientation
DISADVANTAGES • -cost • - stings on injection (buffer with 0.2 mls of 8.4% Sodium Bicarbonate mixed in syringe immediately before administering to kittens/juveniles)
Sedating Dogs • WHAT? • - A.C.P 10 (10 mg Acepromazinemaleate) • - Phenomav 100 mg(100 mg Phenobarbitone) • - Xylazil -20 (20 mg/ml Xylazine Hydrochloride) and Ketamil(50 mg/ml Ketamine hydrochloride) • HOW MUCH • - A.C.P : 1 – 3 mg/kg • - Phenobarbitone : 8 mg/kg • - Xylazine/Ketamine : 0.5 ml of each per 10 kg bodyweight mixed in a syringe
ADVANTAGES • - Cheap (ACP $0.08 per tablet; Phenomav $0.14 per tablet; Xylazine /Ketamine mix $0.42 per ml) • - oral sedation for most dogs • DISADVANTAGES • - Need to ensure tablets are eaten (small breeds/stressed dogs) • - Ketamine is a restricted drug, therefore must be administered by a vet
Sedating Rabbits and Rodents • What? • -Xylazine (20 mg/ml)/Ketamine (50 mg/ml) • How? • -Intraperitoneally (liver - right side of abdomen just below ribs) • How much?
ADVANTAGES • - non-irritant intraperitoneal injection • - fully anaesthetized • - less hazardous to handle than gaseous sedation • - less equipment needed than gaseous sedation
DISADVANTAGES • - Ketamine is a restricted drug, therefore only able to be used by a vet
Tips, Tricks and Techniques • When injecting sedatives, face cat into carrier
No intraperitoneal injections of Lethabarb unless the animal is fully anaesthetised (generally only necessary in neonatal animals, rats, mice and guinea pigs).
