Título Exposure to nitrous oxide in delivery suites at six Swedish hospitals
Información bibliográfica July 2008, Vol.81, No.7, p.829-836. 19 ref.
Resumen Occupational exposures to nitrous oxide in delivery suites in six Swedish hospitals were evaluated, together with various scavenging techniques. 8h time-weighted averages (TWAs) and short-term (15 min) peak exposures were determined for 36 midwives and assistant midwives. Diffusive samplers were used for monitoring, and analysed by thermal desorption and gas chromatography-mass spectrometry (GC-MS). The effect on exposure of different types of scavenging systems was studied by mixed model analysis. Findings are discussed. A large number of TWAs exceeded the ACGIH-TLV. Masks connected to scavenging systems significantly reduced exposures. Furthermore, using a forced general air ventilation system in addition to improved working methods substantially improved the air quality in the delivery suites.
