The Effect of 40 Hz Transcranial Stimulation on the Incidence of Emergence Delirium in Children

The Effect of 40 Hz Transcranial Stimulation on the Incidence of Emergence Delirium After Sevoflurane Anesthesia in Children

Emergence delirium is a complex of perceptual deficits and psychomotor agitation most commonly seen in preschool children in the early post-anesthetic period. It increases the risk of bed falls, accidental catheter removal, surgical wound dehiscence, and delayed discharge in children. Exogenous 40 Hz stimulation can improve cognitive functioning. Therefore, the aim of this study was to explore the effect of 40Hz stimulation on the incidence of emergence delirium in children undergoing vascular malformation surgery under sevoflurane anesthesia.
