WebW. Andrew Kofke, in Cottrell and Young's Neuroanesthesia (Fifth Edition), 2010 Reliable Measurement of Depth of Hypnosis and Analgesia. Bispectral index and patient state index (PSI) monitors have undergone extensive evaluation as monitors of depth of hypnosis, with reasonable evidence for a role in some neurosurgical settings. 188 However, this … WebHowever, the device available for BIS measurement was designed and calibrated for use in anesthesia and is more commonly used to measure cerebral activity during anesthesia (4), and predict movement response to laryngeal mask insertion (5), intubation (6), and skin incision (7). Nonetheless, the BIS is not a specific index of consciousness (8).

WebDec 31, 2024 · Bispectral index (BIS) values are generated from an empirically derived algorithm and are meant to reflect a patient’s hypnotic level during general anaesthesia. The reliability of BIS values is influenced by age, electrical impedance, electrical interference, electromyographic activity, and use of ketamine or nitrous oxide. WebJul 29, 2024 · Cortical electroencephalography-based devices are used to monitor the depth of anesthesia. In this study, we evaluated the values of bispectral index (BIS) and patient state index (PSI) during sevoflurane anesthesia in children. WebBackground. Unexpected awareness is a rare but well-described complication of general anesthesia that has received increased scientific and media attention in the past few years. Transformed electroencephalogram monitors, such as the Bispectral Index monitor, have been advocated as tools to prevent unexpected recall.Methods.
