EEG for Everyone — Atlas Case Submission

Thank you for your interest in contributing to the Atlas section of EEG for Everyone. This chapter shows how patient variability and surgical context change the anaesthetic response and its EEG/DSA expression, through real cases contributed by colleagues with direct experience of each scenario. This form collects the information required to evaluate and prepare your case for inclusion, organised as the anaesthetist experiences it: pre-anaesthetic assessment, induction, and maintenance/emergence. Please complete all mandatory fields (marked *) and ensure that any accompanying files are fully anonymised prior to upload.

All patient-identifying information must be removed from EEG traces, images and supporting documents before submission. Written patient consent (or institutional waiver) is required for every case.

A. Corresponding author & contributors

Details of the submitting author and any co-authors to be credited.

Corresponding author, full name *

Email address *

Institutional affiliation *

Country *

B. Case classification

A structured summary of the clinical case proposed for the Atlas.

Proposed case title *

Patient category *

Keywords (comma-separated)

Clinical summary *

Please include: brief clinical history, EEG acquisition details, description of findings, diagnosis/outcome and the educational point(s) the case illustrates.

C. Surgical details

Urgency, specialty and specifics of the procedure performed.

Type of surgery *

Surgical specialty *

Scheduled for *

Name the exact operation the patient was scheduled for. Use laterality below for side, and include any detail that affects anaesthetic risk (e.g. low rectal resection — higher bleeding risk).

Surgical approach *

Laterality *

Duration of surgery (minutes) *

D. Pre-anaesthesia — patient profile

Demographics and comorbidities as assessed before induction.

Patient age *

Weight (kg) *

Height (cm) *

Comorbidities (tick all that apply)

Hypertension Diabetes mellitus OSA (obstructive sleep apnoea) Asthma / COPD

Current medication (optional)

Difficult airway (VAD) *

Premedication (before entering theatre) *

E. Anaesthetic technique & agents

Induction agents, then the maintenance technique. If target-controlled infusion (TCI) was used, please specify the pharmacokinetic model for each drug administered.

Induction agent(s) (tick all that apply)

Neuromuscular blocker *

Induction technique *

The anaesthetist decides the route on the day — e.g. a child who won't tolerate a cannula may have a mask induction first.

Induction bolus dose(s)

TCI target mode

Induction notes (optional)

Airway device *

Mechanical ventilation mode *

Maintenance technique *

Inhaled anaesthetic gas (tick all that apply)

TCI pharmacokinetic models used (select "N/A" for any drug not administered)

Propofol model

Remifentanil model

Dexmedetomidine model

Sufentanil model

Maintenance adjuvant(s) (tick all that apply)

Regional / neuraxial technique (in addition to the above, tick all that apply)

Peripheral nerve block Epidural Spinal (subarachnoid block) Combined spinal-epidural (CSE) None

Intraoperative opioid(s) (tick all that apply)

Opioid administration (optional)

Postoperative analgesia — opioid (tick all that apply)

Postoperative analgesia — non-opioid (tick all that apply)

PONV prophylaxis (tick all that apply)

Neuromuscular blockade reversal *

F. EEG data and supporting files

Anonymised files only. Accepted formats: PDF, PNG, JPG, TIFF, EDF, ZIP (max file size per the site's upload policy).

Neuromonitoring device *

The upload field below changes depending on the device selected, since each exports raw data differently.

BIS raw data (.zip) *

BIS Vista exports a single folder with an L-prefixed case ID (e.g. L08061015) containing .ara, .e_a, .f_a, .h_a, .m_a, .o_a, .r2a, .spa and .t_a files. BIS Advance exports a case folder containing several subfolders (BIS_…, DSA_…, SNAP_n_…, DH…), each with its own raw files. In both cases, please compress the full case folder as a single .zip before uploading.

SedLine EDF file *

SedLine exports a single EDF file, typically around 30 minutes long.

Raw monitor data *

Upload the raw export from the device. If it consists of multiple files or a folder, please compress it as a single .zip before uploading.

EEG / DSA trend figures (screenshots or exported images, optional)

Signed patient consent / institutional waiver *

Supplementary material (optional)

G. Additional notes

Anything else relevant — e.g. difficult airway management, intraoperative events, deviations from the technique above.

Notes (optional)
