| Abstract |
The sources and atmospheric distribution of trace concentrations of inhalation anaesthetics in the operating theatre are discussed. Scavenging systems (collection of waste gases at the anaesthetic breathing system and disposal procedures) are outlined, and recommendations made for "low-leakage" practices by the anaesthetist, equipment maintenance, and an air monitoring programme to establish the efficacy of the control measures. Careful application will yield an air concentration in the operating theatre of <30ppm nitrous oxide and <0.5ppm halothane. Appendices: fundamentals of physiology, anaesthetic techniques and agents, breathing systems, and test lung; diffusion leakage; distribution of waste gases in air; diagrams and pressure-flow relationships of scavenging components; gas analysis and calibration techniques. |
