ABSTRACT
BACKGROUND: In pediatric anesthesia, minimum alveolar concentration (MAC) guides inhalational agent dosing but may not accurately reflect anesthetic depth. EEG-guided anesthesia has shown benefits in adults but remains underused in children.
AIMS: This study aims to evaluate the effect of EEG-guided anesthesia with SedLine on emergence delirium (ED) and sevoflurane dose in behaviorally noncompliant children undergoing dental procedures under general anesthesia.
METHODS: In this prospective, randomized controlled trial, 100 children aged 4-10 years were randomized to standard anesthesia guided by MAC and conventional clinical signs (standard group) or EEG-guided anesthesia titrated to SedLine parameters (primary target: PSI 25-50; secondary parameter: SEF 10-15 Hz) (EEG-S group). Primary outcome was ED incidence assessed by the Pediatric Anesthesia Emergence Delirium Scale (PAEDS). Secondary outcomes included mean EtSevo values, postoperative pain, rescue analgesia, nausea/vomiting, recovery time.
RESULTS: Median PAEDS scores during the first 120 min postoperatively were significantly lower in the EEG-S group compared with the Standard group (e.g., upon arrival to PACU: 4 [IQR 4] vs. 8 [IQR 4.5]). In addition, the incidence of ED upon arrival in the recovery room was significantly lower in the EEG-S group (17% vs. 43%) and at 10 min postoperatively (17% vs. 37%). The mean end-tidal sevoflurane concentration was statistically lower in the EEG-S group (maintenance EtSevo 1.88 ± 0.25 vs. 1.98 ± 0.20; mean difference = 0.10, 95% confidence interval: 0.006-0.190; p = 0.036). Postoperative FLACC pain scores were also lower in the EEG-S group, representing a potential confounding factor for ED outcomes.
CONCLUSION: EEG-guided anesthesia was associated with lower PAEDS scores and reduced sevoflurane consumption compared with standard management. However, given small EEG-derived differences and potential confounding by postoperative pain, these findings should be interpreted cautiously. Within the applied target ranges, EEG-derived parameters were not independently associated with ED, and specific EEG targets predictive of ED could not be identified.
