BIS monitor

BIS monitor

A device used to give warning that a patient under general anaesthesia might be in a state of awareness or feeling pain. The device is a single electrode ELECTROENCEPHALOGRAM that performs bispectral analysis of the complex waveforms from the brain to produce an index of awareness on a scale in which 100 is full wakefulness.

For this reason, the new version of the BIS monitor (called the bilateral BIS) could be better suited for patients with TBI because it enables recording of BIS and facial EMG parameters for the right (R) and left (L) hemispheres separately, something not possible with earlier BIS devices.
Additionally the probe of BIS monitor (Aspect Medical Systems) was adhered to the forehead and the values were recorded and the patient was given nasal O2 at a rate of 2 lt/min.

A sensor is placed on the patient's forehead, and electroencephalogram (EEG] information is translated by the BIS monitor into a numerical representation of the patient's consciousness level.
The BIS XP technology will provide a number of enhancements for the A-2000(TM) BIS Monitor and BIS Modules to enable expanded performance capabilities for consciousness monitoring.
The recommendation specifies that the BIS monitor should be used with all patients receiving total intravenous anaesthesia and during any type of general anaesthesia with patients considered at high risk of adverse outcomes.
Deep anesthesia is reflected with delta waves (8) and a range between 40 and 20 on the BIS monitor, while burst suppression is reflected by a range of 0 and 20.
