ObjectivesTo describe perfusionist perspectives regarding waste anesthetic gas (WAG) management during cardiopulmonary bypass (CPB) and compare results to existing American Society of Extracorporeal Technology (AmSECT) guidelines and the 2016 National Institute of Occupational Safety and Health Survey of healthcare workers and anesthesia care providers.DesignWe developed a questionnaire with 26 questions covering institutional demographics, use of anesthetic gases, scavenging systems, and air monitoring practices.SettingWeb-based survey.ParticipantsSelf-identified board-eligible perfusionist members of AmSECT, the American Academy of Cardiovascular Perfusion, and the Maryland and Wisconsin State Perfusion Societies in 2022.InterventionsNone.Measurements And Main ResultsOf the 4,303 providers sent the survey, 365 (8.5%) participated. Although 92% of the respondents (335/364) routinely administered inhaled anesthetics via the oxygenator, only 73.2% (259/354) routinely scavenged WAG during CPB cases. Only 6.6% of the respondents (22/336) conducted environmental monitoring for WAG levels. Cited reasons for not scavenging waste gases included a lack of applicable protocols and waste gas scavenging systems, excessive cost, and no need for scavenging.ConclusionsOur findings identify a gap between AmSECT guidelines and current perfusionist behavior and suggest potential strategies for reducing WAG leakage during CPB. Effective management should incorporate hazard awareness training, availability of standard procedures to minimize exposure, scavenging systems, regular equipment inspection, and prompt attention to spills and leaks. In high-risk environments, environmental surveillance for waste gas levels would also contribute to waste gas safety. A comprehensive approach to managing waste anesthetic gases will reduce WAG leakage, help improve health care worker safety, and prevent potential adverse effects of exposure.Copyright © 2024 Elsevier Inc.
