- Abstract
To evaluate the performance of four kinds of carbon dioxide (CO2) absorbents (Medisorb® GE Healthcare, Amsorb® Plus Armstrong Medical, YabashiLime® Yabashi Industries, and Sodasorb® LF Grace Performance Chemicals), we measured their dust production, acceptability of colour indicator, and CO2 absorption capacity in in vitro experimental settings and the concentration of compound A in an inspired anaesthetic circuit during in vivo clinical practice. In vitro, the order of the dust amount was Sodasorb LF > Medisorb > Amsorb Plus = YabashiLime both before and after shaking. The order of the color acceptability was similar: Sodasorb LF > Amsorb Plus = Medisorb > YabashiLime both initially and 16 h after CO2 exhaustion. During exposure to 200 ml.min−1 CO2 in vitro, the period until 1 kg of fresh soda lime allowed inspired CO2 to increase to 0.7 kPa (as a mark of utilisation of the absorbent) was longer with Medisorb (1978 min) than with the other absorbents (1270–1375 min). In vivo, compound A (1.0% inspired sevoflurane) was detected only when using Medisorb. While Medisorb has the best ability to absorb CO2, it alone produces compound A.
