Detaillierte Beschreibung
Electroencephalography (EEG)-guided anesthetic titration has demonstrated significant clinical benefits in both pediatric and adult patients. However, proprietary EEG-based indices widely used for monitoring anesthetic depth are affected by patient age and the specific anesthetic agent used, limiting their validity and generalizability. More recently, titrating anesthetics based on a specific interpretation of EEG waveforms and their oscillatory patterns observed on the spectrogram has gained popularity.
Previous studies indicate that sevoflurane titration based on specific EEG waveforms and oscillatory patterns yields more substantial reductions in sevoflurane exposure than previously reported with proprietary EEG indices. Furthermore, reducing sevoflurane exposure decreases the incidence of EEG burst suppression, results in faster emergence times, and reduces emergence delirium.
However, most of these benefits have been reported in the context of surgeries where intraoperative antinociception was provided via central or peripheral nerve blocks, in the absence of increased intraoperative analgesic and opioid requirements. It remains unclear whether the benefits associated with reduced sevoflurane exposure are also observed in surgeries where intraoperative antinociception cannot be provided through regional blocks. In such cases, antinociception depends primarily on the co-administration of inhaled anesthetics and opioids. Therefore, the clinical benefits of decreasing sevoflurane exposure via electroencephalographic guidance must be weighed against the side effects of higher perioperative opioid requirements.
What will be the impact of strict titration of the hypnotic component using electroencephalography in a painful surgery, in terms of intraoperative opioid consumption and the quality of anesthetic emergence? It is hypothesized that to adjust the sevoflurane dose according to EEG targets in children undergoing surgeries where intraoperative antinociception cannot be provided via regional blocks will result in a reduction of sevoflurane requirements. However, a compensatory increase in intraoperative opioid consumption is expected to be observed, which could subsequently affect the quality and duration of the anesthetic recovery period.
