Abstract
A request was received from the Department of Surgery at Primary Childrens Hospital (SIC-8070) to investigate exposures in operating rooms and recovery room for nitrous-oxide (10024972), ethrane (13838169), halothane (151677), and isoflurane. The NIOSH criteria of 0.5 parts per million (ppm) was exceeded for ethrane in 17 of 24 air samples (71 percent). The 0.5ppm criteria for halothane was exceeded in 13 of 24 samples (54 percent). The 0.5ppm criteria for isoflurane was exceeded in 2 of 24 samples (8 percent). Nitrous- oxide was examined in 32 air samples taken from workers and in 31 of these the concentration exceeded the criteria of 25ppm. During interviews of the medical personnel, there were very few complaints and none suffered any medical condition which they related to exposure. All operating rooms exhibited excessive exposures to ethrane, halothane, isoflurane and nitrous-oxide due to a lack of sufficient air changes per hour. These levels would be significantly lower if adequate ventilation was provided. The method of administering anesthetics differs in a children's hospital, from an adult situation. The authors conclude that a health hazard existed for overexposure to ethrane, halothane, isoflurane and nitrous-oxide in the operating rooms. The authors recommend that the slip connections and high pressure nitrous-oxide connections be checked by the anesthesiologist. An air monitoring system must be in use at all times. Increased ventilation is recommended.
