2023年11月6日 · Assess bispectral index values alongside patient responses and physiological indicators to fine-tune anesthesia levels and ensure patient comfort and safety.

Bispectral index monitor indicating a nearly isoelectric pattern of electroencephalographic activity. The bispectral index is a statistically based, empirically derived complex parameter. It is a weighted sum of several electroencephalographic subparameters, including a time domain, frequency domain, and high order spectral subparameters. [5]

2023年11月6日 · When the bispectral index (BIS) value is maintained below 60, it decreases the incidence of anesthesia awareness. Several neuro monitors based on the processed electroencephalogram or evoked potentials have been developed …

The bispectral index is a statistical numeric value based on bispectral processing of the last 15 to 30 seconds of the harmonic and phase relationship of the frontal lobe EEG data. A score of 90 to 100 represents an awake state; 70 to 80, a moderate sedation state; 60 to 70, a deep sedation state; 40, general anesthesia; and 0, consistent with ...

2024年7月7日 · the resulting algorithm generates a bispectral index (BIS) it has been validated on healthy and now other patient populations; COMPLICATIONS. Benefits. BIS < 60 results in very low levels of post-op recall; shown to lower anaesthetic consumption; slightly quicker awaking; safe with diathermy and defibrillation; Problems

2008年3月13日 · Several brain-function monitors based on the processed electroencephalogram or evoked potentials have been developed to assess anesthetic depth. The most widely used is the bispectral index...

2019年12月31日 · Intraoperative awareness is a distressing complication of general anaesthesia associated with posttraumatic stress disorder. Bispectral index (BIS) values are generated from an empirically derived algorithm and are meant to reflect a …

The Bispectral Index™ (BIS™) monitoring system processes raw EEG information to provide a direct measurement of the patient’s level of consciousness. Proven algorithm. Trusted insight. Too much or too little anesthesia can be associated with challenges such as longer recovery times and postoperative neurocognitive disorders.

Bispectral index (BIS) is a measurement scale based on the electrical activity in the brain, and by using a monitor of brain activity during anaesthesia, the anaesthetist may use this scale to inform the amount of anaesthesia to give to the patient.

2019年12月31日 · Intraoperative awareness is a distressing complication of general anaesthesia associated with posttraumatic stress disorder. Bispectral index (BIS) values are generated from an empirically derived algorithm and are meant to reflect a …
