Indications of Crain et al for Monitoring the Bispectral Index (BIS) in a Pediatric Patient in the Intensive Care Unit (ICU)

 

The bispectral index uses EEG patterns to distinguish wakefulness vs sedation. The BIS may not correlate with the patient's level of comfort.

 

Bispectral Index	Level of Sedation
> 80	light
61 - 80	moderate
41 - 60	deep
<= 40	very deep

 

Indications for monitoring the bispectral index:

(1) The patient is paralyzed (for long-term mechanical ventilation or other reason).

(2) The patient's level of sedation is difficult to assess clinically for other reasons.

(3) The patient is in deep or very deep sedation and is at risk for becoming oversedated.
