Fig. 6. Inspired compound A concentrations and absorbent temperatures resulting from degradation of sevoflurane by fresh and by partially dehydrated absorbents. Compound A concentrations with fresh or dry Amsorb^®were not significantly different from baseline at any time. Compound A concentrations with Amsorb^®were significantly less than those with fresh Baralyme^®and “new” sodalime, and with partially dehydrated “classic” sodalime at 10–45 min. Temperatures were not different between fresh absorbents. Dehydrated Amsorb^®temperatures were significantly less than those of dry Baralyme^®and “classic” sodalime after 5 min.
