Inhalation anaesthetics, exposure and control during veterinary surgery / R.J. Gardner, J. Hampton and J.S. Causton

Sumario: Results are reported for air sampling surveys carried out by the Health and Safety Executive (HSE) in 14 veterinary surgeries. For all personnel the geometric mean (GM) time-weighted average (TWA) exposures to halothane and nitrous oxide over the working period were 2.6 ppm (range: <0.5-119 ppm) and 100 ppm (range 14-1700 ppm), respectively. Since surgery rarely lasted for more than 4 h the corresponding GMs for 8-h TWAs were lower, being 1.3 ppm (range: <0.5-34 ppm) for halothane and 34 ppm (range: 5-530 ppm) for nitrous oxide. The GM exposures of veterinarians and nurses were very similar. The size of the practice and the use of scavening were significant factors in determining personal exposures to inhalation anaethetics; by comparison general ventilation had little effect. The results are compared with earlier data from human surgery, and previous studies of exposure to inhalation anaesthetics during veterinary surgery are brifly reviewed
