Entropy: A Tool for Guiding Delivery of Anesthesia Clinical View

WebResults are expressed as actual number of occurrences, percentage and/or mean ± SD for continuous variables. Results. Part I. ... In this study, OAA/S was a more sensitive monitor of the sedation occurring with spinal anesthesia than was the BIS monitor. Sedation effects appeared to be most pronounced at 60 min. The finding of substantial ... WebFeb 21, 2024 · BIS monitor was used to assess the level of sedation in the intervention arm in all the studies. In the control arm, the sedation assessment tools for CA included the Sedation-Agitation Scale (SAS), Ramsay Sedation Scale (RSS) or subjective CA utilizing traditional clinical signs (heart rate, blood pressure, conscious level and pupillary size). circular cuts on skin

Bispectral Index Monitoring and Intraoperative Awareness

WebBispectral index (BIS) monitoring, an objective measure of the patient's response to sedation, has been used in anesthesia for over a decade. This technology is finding its … WebIt was obtained from the algorithm based on the analysis of a large number of EEGs from volunteers and patients undergoing sedation and general anesthesia with different anesthetic agents. The use of BIS to monitor the depth of anesthesia reduces the incidence of intraoperative awakening and recall, among other benefits. The BIS monitor provides a single dimensionless number, which ranges from 0 (equivalent to EEG silence) to 100. A BIS value between 40 and 60 indicates an appropriate level for general anesthesia , as recommended by the manufacturer. 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 subparameters, including a See more BIS monitoring is widely used in operating rooms and ICUs, as well as in emergency departments. Some of the benefits that have been attributed to it include: • Reduced time to extubation and discharge from the operating room and PACU See more The BIS was introduced by Aspect Medical Systems, Inc. in 1994 as a novel measure of the level of consciousness by algorithmic analysis of a patient's electroencephalogram during general anesthesia. 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 … See more The BIS is an electroencephalogram-derived multivariant scale that, when a drug such a propofol is used, correlates with the metabolic … See more • Anaesthetic machine • Entropy monitoring • Evoked potentials • Respiratory monitoring • Spectral edge frequency See more circular cut out tool
