Abstract

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.
