- (en) The paper of Gardon et al. published in the current issue of the European Journal of Anaesthesiology raises some issues. Although it was not the main outcome of this observational study, its main conclusion ‘the smaller the child the more apparatus deadspace plays a critical role’ is not new: this is well known and it is surprising that a large heat and moisture exchanger (HME) was routinely used in children less than 10 kg, when smaller airway filters are available specifically for smaller infants. In essence, the authors used volumetric capnometry to explore the age/weight related differences on minute ventilation, tidal volume and the effects of dead space during routine anaesthesia. While this represents new data, the conclusions on alveolar ventilation reported in the paper could lead to misinterpretation and deserve some comments, even if most of the considerations below were already discussed in the ‘Limitations’ section of the manuscript.
