Abstract:
This was a prospective study comparing the cost implications between two carbon dioxide (CO2) absorbers, soda
lime (Intersurgical) and AMSORB® PLUS. The study was conducted over two 4-week periods in two dedicated
operating theatres using Datex Ohmeda Aestiva/5 anaesthetic machines. AMSORB® PLUS was used during the first
four weeks and soda lime (Intersurgical) the following four weeks. General anaesthesia was administered as
routinely done but fresh gas flow (FGF) during the maintenance phase was limited to a maximum flow of 2 L/min.
The CO2 absorber was only changed when there was evidence of exhaustion. Total duration of anaesthesia,
sevoflurane (bottles) and CO2 absorber (kg) consumption, and amount of waste product (kg) was calculated at the
end of each study period. The total cost of delivering general anaesthesia was lower in the AMSORB® PLUS group,
RM82.40 (USD19.89)/hour versus the soda lime group, RM91.50 (USD 22.09)/hour (p=0.17), which translates to a
10% reduction in cost per hour. Reduction in sevoflurane consumption in the AMSORB® PLUS compared to the
soda lime group was also not statistically significant (p=0.22). The only significant finding was the reduction in CO2
absorber consumption in the AMSORB® PLUS group as compared to soda lime group (p=0.001). In conclusion,
AMSORB® PLUS consumption was significantly reduced compared to that of soda lime. However, the use of
AMSORB® PLUS did not significantly reduce sevoflurane consumption nor the total cost of delivering general
anaesthesia. Given the superior safety profile, AMSORB® PLUS may be a suitable, cost-effective alternative to soda
lime in the daily practice of anaesthesia.
