Forehead EEG feasible in postanoxic coma

Feasibility and agreement of a self-adhesive EEG electrode set versus conventional EEG in postanoxic coma
Resuscitation · Added 12 May 2026

Comparison of forehead EEG electrodes versus conventional EEG in 51 postanoxic coma patients found forehead recordings were interpretable in 74.1% of cases with moderate agreement, suggesting potential as a screening tool to reduce technician workload.

Study type

Cohort

Design

Prospective comparison of self-adhesive forehead EEG versus conventional EEG

Participants

51 postanoxic coma patients

Main finding

Forehead recordings were of sufficient quality in 74.1% of fragments; agreement was moderate versus standard EEG (κ 0.56) and near perfect for conventional EEG visualised as forehead montage (κ 0.85); noise reduced detection of discontinuous/suppressed patterns.

Caveat

Moderate agreement and reduced detection of suppressed patterns due to noise; ICU setting

Bottom line

Hypothesis-generating

Learning goal

Recognise the limitations of simplified forehead EEG monitoring when assessing suppressed brain activity after cardiac arrest.
