Important Information about Using BIS Monitoring
The BIS EEG VISTA Monitor System is intended for use under the direct supervision of a
licensed healthcare practitioner or by personnel trained in its proper use. The system, and all
its associated parameters, 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 BIS Index, one of the VISTA Monitor output parameters, may be used as an aid
in monitoring the effects of certain anesthetic agents; and its usage with certain
anesthetic agents may be associated with a reduction in primary anesthetic use and a
reduction in emergence and recovery time.
Use of the BIS Index for monitoring to help guide anesthetic administration may be
associated with the reduction of incidence of awareness with recall in adults during general
anesthesia and sedation.
BIS is a complex monitoring technology intended for use 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. As with any monitored parameter, artifacts and poor
signal quality may lead to inappropriate BIS values. Potential artifacts may be caused by poor
skin contact (high impedance), muscle activity or rigidity, head and body motion, sustained
eye movements, improper sensor placement and unusual or excessive electrical interference.
BIS values should also be interpreted cautiously with certain anesthetic combinations, such
as those relying primarily on either ketamine or nitrous oxide/narcotics to produce
unconsciousness. Due to limited clinical experience in the following applications, BIS values
should be interpreted cautiously in patients with known neurological disorders and those
taking other psychoactive medications.
The BIS education site, www.biseducation.com, offers relevant information and published
articles on the clinical use of BIS. In addition, there is a “Monitoring Consciousness Using
the Bispectral Index during Anesthesia” Clinician’s Pocket Guide available on the website
and through your local Aspect Representative.
