WebBackground. The Bispectral Index (BIS) and the Patient State Index (PSI) quantify depth of anesthesia by analyzing the electroencephalogram. The authors examined the response of BIS and PSI to sevoflurane anesthesia.Methods. In 22 patients, sevoflurane anesthesia was induced by inhalation with a tight-fitting facemask and was maintained via a … WebNov 3, 2024 · BIS < 60 results in very low levels of post-op recall. shown to lower anaesthetic consumption. slightly quicker awaking. safe with diathermy and defibrillation. …

WebA BIS value between 40 and 60 indicates an appropriate level for general anaesthesia, as recommended by the manufacturer. The BIS monitor thus gives the anaesthetist an indication of how "deep" under anaesthesia … WebNo premedication was given. Anesthesia was induced with sevoflurane by mask in 60% N 2 O/O 2 or with a single bolus dose of propofol IV. BIS measurements were delayed for a minimum of 20 min after propofol. Anesthesia was maintained with sevoflurane in nitrous oxide and oxygen (50%–60% N 2 O). However, no additional sedative or hypnotic drugs ... fitted wardrobes sloping ceiling
Recommendations for standards of monitoring during anaesthesia …
WebOct 23, 2024 · Throughout the lifespan of the BIS device, emphasis has shifted from ‘depth of anesthesia,’ through ‘depth of hypnosis’ to ‘probability of recall.’ No device currently achieves the goal of being an ideal “depth of anesthesia” monitor (Table 1 ) and predicts the effect of a balanced hypnotic/analgesic approach to patient management. 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 anesthetic agents to a specific bispectral index during general anesthesia in adults (and children over 1 … 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. … 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 • Anaesthetic machine • Entropy monitoring • Evoked potentials • Respiratory monitoring • Spectral edge frequency 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 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 … See more • Grover VK, Bharti N (2008).
