Entropy measurement limitations
•
Entropy measurement is not indicated for pediatric patients younger than two years old.
•
Entropy is not validated with patients undergoing sedation.
•
Unusual or excessive electrical interference is a potential cause for artifact. During
extended periods of electrocautery there may not be any good EEG epochs, and Entropy
values will not be displayed.
•
ECG, frequent eye movements, coughing, muscle rigidity and patient movement cause
artifact and may interfere with the measurement. Epileptic episodes may also cause
interference.
•
Entropy readings may be inconsistent when monitoring patients with neurological
disorders, traumas or their sequelae.
•
Entropy readings may be inconsistent when using benzodiazepines, nitrous oxide or
ketamine as anesthetics.
•
Psychoactive medication or very high opiate doses may suppress EEG and cause
inconsistent Entropy readings.
•
Cooling the patient may suppress their EEG and cause inconsistent Entropy readings.
Checklist
Check that:
•
Electrode gel is moist.
•
Electrodes have good skin contact.
•
Electrodes are positioned correctly.
