Abstract

The increased use of sevoflurane has led to concerns about exposure of anaesthesia personnel to trace amounts of this agent. When cuffed tubes are used in modern, climatized operating theaters, exposure of personnel to traceconcentrations of these anesthetic is minimal. However, there is little data for this anaesthetic with regard to inhalational induction and use of uncuffed tubes. Our study therefore investigated 1,) exposure to sevoflurane and nitrous oxide during inhalational induction and 2,) exposure to these agents during use of cuffed (adult patients) and uncuffed (pediatric patients) tubes. The operating theaters were equipped with modern air-conditioningand waste gas scavenging systems. Measurements were taken within the breathing zones of surgeon and anaesthesiologist by directly displaying infraredspectrometry. We found very low concentrations of the inhalational anaesthetics within the breathing zones of both anaesthesiologist and surgeon. During inhalational induction, mean exposure of the anaesthesiologist to sevoflurane was 3.14 +/- 1.01 ppm (children) and 2.25 +/- 0.66 ppm (adults), Exposure to both nitrous oxide and sevoflurane was slightly higher when uncuffed tubes were used with children as compared to adults with cuffed tubes. Distance from tube and/or trachea is the most important factor with regard to exposure, Exposure of the surgeon, who worked closer to the tube, was higher than of the anaesthesiologist. Applicable health regulations for exposure to nitrous oxide were not violated. To date, there are no regulations for sevoflurane in Germany. However, all measured concentrations of this anaesthetic were well below the legal limits for enflurane (20 ppm) and isoflurane (10 ppm). We therefore conclude that, regardless of anaesthesia technique employed, the use of sevoflurane is safe from the standpoint of occupational health regulations, More stringent regulations for the new anaesthetic are not necessary.
