In response to a request from employees to evaluate exposures to waste anesthetic gases and vapors at the Presbyterian Day Surgery Unit (SIC-8062), located in Albuquerque, New Mexico, personal and area air sampling and leak detection testing was carried out for nitrous-oxide (10024972) (N2O) and halogenated anesthetic agents in the six operating rooms at this facility. Nitrous-oxide concentrations ranged from not detectable to 95 parts per million (ppm) with a mean of 20ppm. Five of the samples exceeded the NIOSH limit of 25ppm for N2O during anesthetic administration. Ethrane (13838169) levels in 14 personal and area air samples ranged from less than the limit of detection to 3.63ppm with a mean of 0.31ppm. Isoflurane (26675467) and halothane (151677) were below the limits of detection. The ventilation system in use changed the air in excess of 20 times per hour. However, during a portion of surgical procedures the system was not operating, resulting in a higher than normal exposure level in three of the operating rooms. The authors conclude that a potential for overexposure to nitrous-oxide and ethrane existed at the time of the survey. The authors recommend correction of the leakage from the spirometers on the anesthetic carts, and examination and modification of the general ventilation system to prevent future shutdowns.
