“…Thomasson et al placed a zeolite filter to the Y-connector, based on the principle of heat-moisture exchanger, thus the amount of gas use has been halved [55]. The development of the so-called anesthetic conserving device was based on this principle [56,57].…”

The harmful effect of inhalational anesthetics on the working environment of anesthetists is one of most controversial areas, where speculations can easily arise. In the present review the authors summarize the possible sources of environmental pollution in the operating theatre with special emphasis on the importance of air suctioning and air conditioning systems. A full-spectrum of the previously published animal and human studies is provided about the possible health hazards of inhalational agents including effects on the central nervous, reproductive and hematologic systems, on the liver functions and also on the carcinogenesis. A list of the proposed measures to decrease pollution to the minimum in the operating theatre environment is provided. It is concluded that according to the present knowledge, the use of inhalational agents may be considered safe if the prescribed limits of halogenated anesthesia gases are met.

The intensive care unit (ICU) environment is often perceived to be hostile and frightening by patients due to unfamiliar surroundings coupled with presence of numerous personnel, monitors and other equipments as well as a loss of perception of time. Mechanical ventilation and multiple painful procedures that often need to be carried out in these critically ill patients add to their overall anxiety. Sedation is therefore required not only to allay the stress and anxiety, but also to allow for mechanical ventilation and other invasive therapeutic and diagnostic procedures to be performed. The conventional intravenous sedative agents used in ICUs suffer from problems of over sedation, tachyphylaxis, drug accumulation, organ specific elimination and often lead to patient agitation on withdrawal. All this tend to prolong the ventilatory as well as ICU and hospital discharge time, which increase the risk for infection and add to the overall increase in morbidity, mortality and hospital costs. In 2005, the anaesthetic conserving device (AnaConDa®) was marketed for ICU sedation with volatile anaesthetic agents. A number of trials have shown the effectiveness of using volatile anaesthetic agents for ICU sedation with the AnaConDa device. Compared with intravenous sedatives, use of volatile anaesthetic agents have resulted in shorter wake up and extubation time, lesser duration of mechanical ventilation and faster discharge from hospitals. This review shall focus on the benefits, technical pre-requisites and status of sedation with volatile anaesthetic agents in ICUs with the AnaConDa® device.

SummaryWe report the first clinical application of a new anaesthetic agent-saving device. The principles of a heat±moisture exchanger have been further developed to create a device that reduces inhalational agent consumption. Sixteen patients were randomly allocated to receive isoflurane through either a vaporiser or through the agent-saving device. A coaxial Mapleson D system (Bain) was used in both groups. A standard ventilatory setting was used, aiming for normocapnia. Mean (SD) isoflurane consumption was 24.5 (2.8) ml.MAC-hour 21 with the vaporiser, compared with 15.2 (3.0) ml.MAC-hour 21 with the new device (p , 0.05). This corresponded to a 40% saving in the consumption of isoflurane. The amount of isoflurane that was scavenged to the atmosphere was reduced by an average of 55%.
