The effects of lowering fresh gas flow during sevoflurane anaesthesia: a clinical study in patients having elective knee arthroscopy

Brief review: Theory and practice of minimal fresh gas flow anesthesia

“…13 Weiskopf and Eger et al 14 have described the impact of a significant reduction in anesthetic consumption and the subsequent cost reduction by reducing the fresh gas flow for the commonly used inhaled anesthetics, and this impact has also been shown in everyday clinical practice. 15,16 Doolke et al 17 conducted a study wherein the consumption of sevoflurane was measured during anesthesia for elective knee arthroscopy. Patients were randomized to receive one of three fresh gas flow rates, i.e., 1.5, 3, or 6 LÁmin -1 , using sevoflurane and O 2 :N 2 O in a ratio of 1:2 after intravenous induction with fentanyl and propofol.…”

Sevoflurane requirements during ambulatory surgery: a clinical study with and without AEP‐index guidance

“…However, ambulatory surgery is becoming an increasingly dominant area in anesthesia, and may be of most interest for those monitors attempting to achieve the closest possible titration of anesthetic depth in order to safely reduce turnaround times, and improve emergence and recovery times. In previous studies of similar surgical procedures and anesthetic techniques, we have shown the benefits of using nitrous oxide and of decreasing the fresh gas flow (12, 13). Furthermore, the alternate technique, the BIS monitor, has been shown to have potential anesthetic as well as time‐saving effects in ambulatory patient populations (14–16).…”

Minimal fixed flow anesthesia for off-pump coronary artery bypass surgery: A parallel randomized trail

“…Minimal flow anesthesia is associated with better preservation of airway moisture and less heat loss [ [1] , [2] , [3] ]. Decreased gas waste also reduces costs [ [4] , [5] , [6] , [7] ]. The total amount of vaporized anesthetics is reduced and thus risk for unnecessary work place contamination is decreased as well as the amount released into the atmosphere and subsequent impact on the global ecosystem [5, [8] , [9] , [10] ].…”
