Abstract
This present study was designed to describe waste anesthetic gas (WAG) exposures in veterinary practices during small and large animal surgical procedures and to note factors contributing to these exposures. A survey was conducted among 11 counties in eastern Colorado for the purpose of determining the usage of inhalation anesthetics and to assess the exposure of veterinarians and their assistants to WAG. In 80.8 percent of the 210 practices surveyed, inhalation anesthetics were used. The size of the patient, the type of breathing system and the use of scavenging systems each influenced the waste anesthetic concentrations available. Scavenging systems were used in only 3 of 28 practices surveyed, but resulted in marked decreases in waste anesthetic concentrations. No significant effect was noted on waste anesthetic concentrations due to the ventilation rate. No effect on breathing zone concentration was noted by the use of dilution ventilation. The endotracheal tube and occasionally the anesthetic machine were the major sources of leakage of anesthetic gases.
