WebDuring surgery under general anesthesia, the patient expects to be unconscious and to not experience pain. 10 Both inhaled and intravenous agents are commonly employed to achieve that goal. When inhaled agents are used, end-expired anesthetic agent monitoring can insure that the inhaled anesthetic agent and appropriate dose are being delivered. ... WebApr 6, 2024 · Processed EEG monitoring, or the bispectral index (BIS) monitor, has been correlated to sedation scales with varying success. 8; BIS monitoring has many limitations in children including the inability to provide age-specific values, varying reliability with specific drugs, and marked overlap when trying to distinguish between levels of sedation.

WebThe Bispectral Index (BIS™) monitoring system enables anesthesia professionals to access processed EEG information as a measure of the effect of certain anesthetics during patient care. BIS cannot be used as the sole monitor of anaesthesia, as it is affected by several other factors, including the anaesthetic drugs used (BIS is relatively insensitive to agents such as ketamine and nitrous oxide ), and muscle movement or artefact from surgical equipment. See more Bispectral index (BIS) is one of several technologies used to monitor depth of anesthesia. BIS monitors are used to supplement Guedel's classification system for determining depth of anesthesia. Titrating See more The bispectral index is a statistically based, empirically derived complex parameter. It is a weighted sum of several electroencephalographic … See more BIS monitoring is widely used in operating rooms and ICUs, as well as in emergency departments.

This is used in conjunction with other … See more Some of the limitations of this form of processed EEG monitoring are: • Unreliability with certain drugs, such as ketamine, nitrous oxide and ephedrine. Ketamine may … See more The BIS is an electroencephalogram-derived multivariant scale that, when a drug such a propofol is used, correlates with the metabolic rate of glucose. Both loss of consciousness and awakening from anesthesia are correlated with this scale. The efficacy … See more rayner hoff project space national art school
