Feasibility and Safety Properties of Metabolic Flow Anesthesia Driven by Automated Gas Control in Pediatric Patients

General anesthesia will be induced via intravenous agents, and anesthesia maintenance will be provided via inhalation for all the patients. The maintenance will be provided with sevoflurane using automated gas flow with the selected speed of 8. The anesthesia machine indicates amount of sevoflurane inhaled, inspired and exhaled oxygen, carbon dioxyde, air and sevoflurane concentrations. Accordingly these data and actual flow rate will be recorded every 15 minutes.
