Euthanasia
2000 Report of the AVMA Panel on
Euthanasia
http://www.avma.org/resources/euthanasia.pdf
Guidelines for Tranquilizers &
Analgesics/Anesthetics
The appropriate use of analgesics, tranquilizers, and anesthetic agents
to prevent pain, distress, and suffering in research animals is mandated by
Public Law 89-544 (Animal Welfare Act) and its amendments, PHS policy, and
institutional policies. Assistance in selecting suitable agents, dosages,
and routes of administration can be obtained from the veterinary staff in
LAS. Some general recommendations for anesthetic and analgesic agents and
doses are listed below. Specific information can be obtained from the LAS
veterinary staff at ext. 1-3421.
Management of Pain and Distress
Pain and distress greater than that induced by injections or simple
percutaneous blood sampling should be relieved by the use of anesthetics
and/or analgesics. The use of ether is prohibited.
The following charts describe the commonly used anesthetics and
analgesics at MCG. You must have a DEA License to purchase controlled drugs (barbiturates, valium, butorphanol,
buprenorphine, morphine, etc.) Ketamine is a
Schedule III controlled drug as of August 12, 1999. Paralytic agents (pancuronium,
succinylcholine, etc.) are not analgesics and must be used in combination
with anesthetics during painful procedures. Animals must be monitored
for changes in heart rate and blood pressure parameters to insure adequate
levels of anesthesia.
The veterinary staff welcomes your questions regarding the use of
new/different anesthetic agents for your procedures and can be reached at
ext. 1-3421.

Buprenorphine Jello
Recipe for rodent analgesia
Feed Jello
without the drug to get the animals accustomed to the Jello. |
Synapse Volume 25 #3, September 1992, pp36-37
1. Decide on the dose (0.1-0.5 mg/kg) is recommended.
(0.025-0.10mg/250g)
2 Determine dosage. Plan on one ml volume of Jello per average weight
of rat, thus, for example, 0.33 ml Buprenex per 0.66ml of jello/250g
rat.
3. Making enough Jello for twice daily dosing for up to 4 days.
Strawberry seems to be the favorite.
4. Follow the Jello recipe up to the part where you dissolve the
Jello in hot liquid. Reduce the volume of cold water by the volume of
Buprenex you will be adding first. Add the cold H2O. Wait until mixture
is less than 90F before adding Buprenorphine. Pour into ice cube trays @
4 ml/section. Freeze and administer 1 cube/4 rats twice daily.
5. Dose by giving 1/4 of a 4 ml cube per rat. place on cage floor on
top of rodent food. |

Applied to the shaven thorax. Use a small amount of super glue to each
corner to help adhesion. No bandage is required. You should apply the
patch 3-4 hours prior to surgery. The patch is then removed 3-5 days
later. Studies show steady serum levels that last at least 104 hours. Do
not use heating pads because this will
increase absorption. |
