Adaptation to the waste anesthesia gas system: Gaps in knowledge and opportunities for positive environmental impact
Canisters containing activated charcoal are commonly
used in the laboratory setting to collect waste
anesthetic gas (WAG). This requires the weighing of
the WAG canister after each use and for investigators
to maintain an accurate time log of anesthesia
duration. A typical rodent anesthesia station may
include the use of 3 WAG canisters; one for the
anesthesia induction box, one for the operative table,
and one for gas monitoring. To simplify the
anesthesia breathing circuit, we have developed a T
connector that replaces the need for having multiple
WAG canisters. The T connector directs the waste
anesthetic from multiple sources; the anesthesia
induction box, operative table and gas monitor into a
single WAG canister. Use of the T connector
appears to be a safe, acceptable device that
conveniently directs waste gas while improving
charcoal adsorption within the canister. In addition,
this device may have a positive impact on the
environment with a secondary benefit of possible
cost savings associated with the purchase and
disposal of the hazardous waste contents.
