MONITOR COVIDIEN BIS

Bispectral index (BIS) monitoring systems allow anesthesiologists to access EEG information processed as a measure of the effect of certain anesthetics during the care of the patients they are monitoring. The clinical impact of BIS monitoring has been demonstrated during several controlled and randomized studies which highlight the advantages of BIS monitoring in improving anesthetic care, including patient safety. As BIS monitoring may be new to some anesthesiologists, it is essential to identify the fundamental elements of BIS technology and to appreciate the relationship between BIS monitoring information and the patient's clinical condition. Before using BIS monitoring information to support anesthesia care, it is also useful to consider important situations and limitations that may influence the BIS value.
