Bispectral index
CAUTION
When connecting or disconnecting BIS, take care not to touch
the exposed contacts of either connector. Damage due to
electrostatic discharge may result to the equipment.
BIS indications for use
The BIS module is intended for use by personnel trained in its proper use. It is intended
for use on adult and pediatric patients within a hospital or medical facility providing
patient care to monitor the state of the brain by data acquisition of EEG signals.
The Bispectral index (BIS), a processed EEG variable, and one component of the BIS
module, may be used in adults as an aid in monitoring the effects of certain anesthetic
agents. The Bispectral index is a complex technology, intended for use only as an
adjunct to clinical judgement and training. In addition, the clinical utility, risk/benefit,
and application of BIS have not undergone full evaluation in the pediatric population.
BIS measurement limitations
●
This measurement is not available in the NICU software package.
●
E-modules used for this measurement are not suitable for use with neonatal
patients.
●
BIS is a complex monitoring technology intended for use only as an adjunct to
clinical judgment and training. Clinical judgment should always be used when
interpreting BIS in conjunction with other available clinical signs. Reliance on BIS
alone for intraoperative anesthetic management is not recommended.
●
BIS values should be interpreted cautiously with certain anesthetic combinations,
such as those relying primarily on either ketamine or nitrous oxide/narcotics to
produce unconsciousness.
●
External radiating devices may disturb the measurement.
●
Poor signal quality may lead to inappropriate BIS values.
●
Artifact may lead to inappropriate BIS values. Potential artifact may be caused by
unusual or excessive electrical interference or high EMG activity like shivering,
muscle activity or rigidity, sustained eye movements, head and body motion. Also,
improper sensor placement and poor skin contact (high impedance) may cause
artifact and interfere with the measurement.
●
Due to limited clinical experience in the following applications, the BIS value should
be interpreted cautiously in patients with known neurological disorders and those
taking psychoactive medications.
BIS points to note
●
Make sure that the sensor connectors of the patient interface cable are not in
contact with fluids.
●
BIS sensors are disposable, for single patient use only, and not made with natural
rubber latex.
●
Check the sensor expiration date on the sensor package.
●
Do not use a sensor for more than 24 hours.
●
Use only Covidien BIS sensors.
