Title Evaluation of the pollution of operating rooms by anaesthetic gases at the Grenoble Regional Hospital, and preventive measures taken
Original title L'évaluation de la pollution des blocs opératoires par les gaz anesthésiques au centre hospitalier régional de Grenoble et les mesures de prévention mises en ¿uvre [in French]
Bibliographic information 1983, Vol.44, No.7, p.499-502.
Abstract Atmospheric concentrations of anaesthetic gases were measured before and after introduction of improved methods of administration and improved ventilation; 2 methods of determination gave similar results. In poorly ventilated operating rooms, nitrous oxide reached levels of 1500-2000ppm, and halothane reached 35ppm. In properly ventilated rooms, average nitrous oxide concentrations during the maintenance phase of anaesthesia were 16-831ppm. Blood levels of nitrous oxide and halothane in operating-room personnel increased steadily during operations. The given combination of improvements reduced ambient concentrations to about 25ppm for nitrous oxide and 2ppm for halothane.
