Gas Chromatography in the Low Concentration Determination of Nitrous Oxide and Volatile Anaesthetics
Anaesthetic pollution is of interest to people subject to low concentrations of all types of gases and volatile anaesthetic during occupational activities. The decrease in recent years in the number of relevant publications does not necessarily mean that pollution has gone away or that the problem has been solved. A number of coincidental factors have brought the matter back into consideration....
متن کاملA comparison of desflurane consumption according to fresh gas flow
provided the original work is properly cited. CC The consumption of volatile agents during general anesthesia can be altered by fresh gas flow (FGF), and it is known to be better to maintain an anesthetic effect with a lesser amount of volatile anesthetics because cost considerations, as long as it does not present a safety problem. A previous study reported that the consumption of sevoflurane ...
متن کاملThe impact of fresh gas flow on wash-in, wash-out time and gas consumption for sevoflurane and desflurane,
Low-flow anaesthesia is considered beneficial for the patient and the environment, and it is cost reducing due to reduced anaesthetic gas consumption. An initial high-flow to saturate the circle system ( ) is wash-in desirable from a clinical point of view. We measured the wash-in and wash-out times (time to saturate and to eliminate the anaesthetic agent, AA), for sevoflurane and desflurane, ...
متن کاملBreathing systems: effect of fresh gas flow rate on enflurane consumption.
The vaporization rates of enflurane were measured in 412 anaesthetics using appropriate fresh gas flow rates in Bain (12 litre min-1), Magill (6 litre min-1) and circle systems (3 litre min-1, 1 litre min-1 and "closed"). In all patients reducing the fresh gas flow rate resulted in lower enflurane consumption. The percent savings were 18-86% depending on the initial fresh gas flow rate and the ...
متن کاملThe effect of low fresh gas flow rate on sevoflurane consumption
BACKGROUND In an era of medical cost containment, cost-effectiveness has become a major focus in healthcare. The effect of a new policy on the use of low fresh gas flow during maintenance of general anesthesia with volatile anesthetics was evaluated. METHODS The numbers and duration of general anesthesia cases using sevoflurane 5 weeks prior to and 15 weeks after policy implementation were re...
