Monitoring anesthesia depth in children is challenging. Pediatric anesthesiologists estimate general using indirect methods such as pharmacokinetic models and neurovegetative reflexes. The application of processed electroencephalography may help to identify the correct (i.e., patient state index between 25 50).To determine median values spectral edge frequency 95% undergoing conducted according evaluation depth. relationships monitoring depth, type anesthesia, age subgroups, postoperative delirium were also assessed.A prospective observational study on (aged 1-18 years) surgery longer than 60 min. SedLine monitor novel pediatric sensors (Masimo Inc., Irvine California) applied. Patient levels recorded for duration until discharge ward at predefined time points.In 111 enrolled children, level end induction was (22-32) ranged from 26 (23-34) 28 (25-36) maintenance phase. extubation 48 (35-60) 69 (62-75) operatory room. Median right/left 10 (6-14)/9 (5-14) Hz phase (6-14) 12 (11-15) both hemispheres. At extubation, 18 (15-21)/17 (15-21) Hz. We observed 39 episodes burst suppression 20 patients (19%). not different inhalational intravenous those added locoregional anesthesia. Children <2 years displayed significantly higher older (p = .0004). presence a episode associated with PAED (OR 1.58, CI 0.14-16.74, p` .18).NonpEEG-guided led low range recommended unconsciousness frequent suppression. generally below 2 years.
