Importance of BIS monitoring in sedation procedures and to attain optimum depth of anesthesia: a case series

Abstract

Bispectral Index (BIS) monitoring has gained popularity during the recent past, in selected cases. It uses a processed Electroencephalograph (EEG) to provide a value between 0 and 100, indicating brain activity and anesthetic depth. Monitoring the depth of anesthesia is a critical aspect of ensuring patient safety during medical procedures. The bispectral index (BIS) monitor is pivotal in this process. Maintaining BIS values within the range of 40 to 60 is essential to prevent anesthesia awareness and mitigate potential long-term psychological consequences.
