Summary High flows of halothane and N 2 O are commonly used in children during induction of anaesthesia. We prospectively evaluated the efficiency of a double mask system in children, during inhalational induction with photoacoustic infrared spectroscopy. Thirty‐two children 5 days to 8.5 years of age were studied. Anaesthesia was induced with inspired halothane concentrations of 2–3% and N 2 O 50–70% in 6–8 litres of freshgas flow via a Jackson‐Rees breathing system. Children were randomly assigned into two groups. Anaesthesia was induced in group 1 using a Rendell‐Baker mask with a regular scavenging device (25 1·min −1 ). In group II a double‐mask system was connected to an active scavenging system (580 1 min −1 ). Halothane and N 2 O were measured at 10 cm below the chin of the anaesthesiologist. We could demonstrate that the use of double‐mask system with a regular scavenging device substantially reduced the exposure of the anaesthesiologist to halothane by 89% and to N 2 O 80% respectively during inhalational induction.
