| Resumen |
The level of nitrous oxide (N2O) contamination in the breathing zone of anaesthesiologists was measured while they administered inhalation anaesthesia by mask to five patients. A mask gas-scavenging attachment was used for 30min and then removed while anaesthesia continued for a further 30min. The levels of N2O with and without the scavenging attachment were compared. Use of the scavenging attachment reduced N2O contamination from >150ppm to <5ppm, a level well below the 25ppm limit recommended by the US National Institute for Occupational Safety and Health. The device consists of a clear plastic drape that covers the patient's face, and a suction tube connected to a vacuum line. |
