Seeing the wood for the trees: Insights into reducing inhalational agent consumption

“…Any steps to reduce desflurane consumption are a good thing. The decrease in desflurane consumption described in the study by Mostad et al 1 is the equivalent to 15‐30 kg CO 2 for every case lasting an hour or more. In our hospital around 12 000 anaesthetics each year last longer than 75 min.…”

“…The second interesting aspect of the work of Mostad et al, is the difference they found in desflurane consumption between the two delivery systems in automatic mode 1 . Total desflurane consumption was statistically significantly less with Aisys than with Flow‐i at both 9 and 30 min and the difference persisted at 60 min, although not statistically significant at this point.…”

“…In this issue of the journal, Mostad et al 1 compared consumption of desflurane with manual low flow or with automated delivery in two different delivery systems, the Aisys CS 2 from GE HealthCare and the Flow‐i from Marquet (now Getinge). They found that using automated agent delivery systems reduced desflurane consumption by between 20% and 40% in the first 60 min of anaesthesia.…”
