The report by Mierdl and colleagues demonstrated that occupational exposure to insoluble inhaled anesthetic agents during cardiopulmonary bypass (CPB) exceeded National Institute for Occupational Safety and Health (NIOSH) standards. Ambient desflurane concentrations of 0.620.82 ppm exceeded the NIOSH limit of 0.5 ppm even when it was used only before CPB. Environmental contamination would have been greater if inhaled anesthetics were administered during CPB or if the more commonly used soluble agent, isoflurane, was administered.
The hazards of occupational exposure to volatile anesthetics are well established. NIOSH recommends, and other hospital accrediting groups
