Description:At the request of management, an environmental evaluation was made of possible exposure to waste anesthetic gases at the Memorial Hospital of Southern Oklahoma (SIC-8070), Ardmore, Oklahoma. The hospital has six surgery rooms and a recovery room. During this evaluation four of the six were in use. Samples were taken for ethrane (13838169), halothane (151677), isoflurane (26675467), and nitrous-oxide (10024972). Of 22 air samples taken, two exceeded the NIOSH criteria for ethrane of 0.5 parts per million (ppm); one exceeded NIOSH criteria for halothane of 0.5ppm. None exceeded the isoflurane NIOSH criteria of 0.5ppm. One exceeded the nitrous-oxide standards of 25ppm. No leaks were found in the anesthesia administering machine, pop off valve scavenging system or any other area of the operating room. About 26 air changes per hour occurred in the operating rooms. The four elevated exposures were attributed to improper fit on an intubation tube and face masks. The authors conclude that a hazard from exposure to waste anesthetic gases did not exist at this facility. The authors recommend that checks be continued on all parts of the anesthetic gas administering system for wear and possible leakage, that care be exercised in choosing proper fitting face masks and intubation tubes for patients, and that air monitoring with the passive dosimetry be continued.
