The effect of Fresh Gas Flow on the speed of inhalational induction with sevoflurane in children

Abstract

Sevoflurane, due to its lack of pungent odor, mild induction characteristics and low blood-gas separation coefficient, leads to fast induction and recovery with a high cardio-respiratory safety factor and is therefore used in pediatric surgery. The purpose of this study was to investigate the effect of fresh gas flow rate on the speed of inhalation induction with sevoflurane in children. Method: After applying the inclusion and exclusion criteria, 60 children aged between 6 months and 8 years and with ASA class I and II candidates for elective orthopedic surgeries were divided into three separate groups based on the amount of fresh gas flow (FGF) during inhalation induction. they started studying. Demographic information, anesthetic characteristics and vital signs of patients were evaluated. Results: No significant difference was observed in terms of demographic information and surgical characteristics between the studied patients. There was no significant difference in terms of this factor between the study groups. The loss of eyelid reflex among group C patients was significantly higher than group A patients. The time required for successful vein removal in group C patients was longer than group A and B patients. There was no significant difference between the study groups in terms of the time of rhythmic breathing, the time of loss of trapezius muscle stimulation, and the time of LMA insertion after no response to trapezius muscle stimulation. There was no difference in terms of complications during induction of anesthesia between the study groups.
