Comparison of DHT Duration in Geriatric Patients Using BIS Monitoring

Bispectral Index (BIS), that was introduced in 1992, is a tool that monitors the depth level of hypnosis through data processing of an electroencephalogram using computer algorithm and presented in the form of processed EEG. Utilizing BIS as a monitoring tool has shown effectiveness in reducing recovery time, prevent awareness, and bring down the amount of anesthesia agent however, as of now, it has not been incorporated into the 2020 American Society of Anesthesiologists (ASA) standard procedure on anesthesia monitoring. aims to comparing the deep hypnotic time duration on two group of geriatric patients which undergoes general anesthesia with BIS monitoring compared to standard monitoring.
