During the past 15 years, there has been a growing interest in low flow closed-circuit anesthesia. It is an admitted fact that the chief incentive motivating this interest has been the realization of wasteful nature of high flow anesthesia where more than 80% of the administered agent may be wasted. There have been a number of developments since previous reviews which affect the issue. One is the advent of newer agents that are more expensive, and another is the introduction of the laryngeal mask which makes possible a leak proof linking attachment from a spontaneously breathing patient to the anesthesia system without the reliance of tracheal intubation. A further influence is the universal availability of C02 monitoring which makes remarkable reduction of fresh gas flow (FGF) possible in the standard system without concern about insufficient CO2 wash-out to soda lime. Low flow in closed system is not only economical but also a technique that permits observation of the interaction between patient and anesthesia system such as the uptake and distribution of agent as well as the physiological state of the patient. All these are the crucial reasons why they deserve to be more widely used. |
