Authors' recommendations:
Summary and ConclusionsSBU’s appraisal of the evidence: EEG-based monitoring of anesthetic depth is intended to complement traditional monitoring methods during anesthesia. Its primary aim is to adapt anesthesia to individual needs so patients can recover more quickly and be at lower risk for awareness while under anesthesia.
Patients at normal risk of awareness who undergo elective surgery
EEG-based monitoring of anesthetic depth reduces by a few minutes the early phase of recovery after intravenous anesthesia (Evidence Grade 3)*. The time saved has not been shown to have any clinical or economic significance. Whether or not monitoring of anesthetic depth affects the early phase of recovery after inhalational anesthesia cannot be determined (Contradictory Scientific Evidence)*. Regarding the later phase of recovery (eg, time until discharge), scientific evidence on the effects of EEG-based monitoring of anesthetic depth is contradictory*. Whether or not EEG-based monitoring of anesthetic depth reduces the risk of awareness during anesthesia cannot be assessed (Insufficient Scientific Evidence)*. Whether or not EEG-based monitoring of anesthetic depth has any effect on patient satisfaction, or on the incidence of post-anesthesia nausea/vomiting, cannot be determined (Contradictory Scientific Evidence)*.Patients at high risk of awareness during anesthesia, or who undergo emergency surgery
Whether or not EEG-based monitoring of anesthetic depth in risk patients has a positive effect on post-anesthesia recovery (Insufficient Scientific Evidence)*, or reduces the risk of awareness during anesthesia (Contradictory Scientific Evidence)*, cannot be determined.In summary, as regards general anesthesia, the scientific evidence is inadequate to support routine use of EEG-based monitoring of anesthetic depth aimed at reducing the incidence of awareness or decisively improving patient recovery.
