GCS correlated with Bispectral Index

What is it about?

Accuracy of consciousness level assessment is very important. It may determine and influence further clinical decisions, thus influences patients’ outcomes. The widest method in determining the level of awareness is the Glasgow Coma Scale (GCS). Despite its common use, GCS scores obtained by one clinician may differ from others depending on their interpretations and past experience. One of the tools used to assess the level of consciousness objectively is bispectral index (BIS). The aim of this study was to identify the correlation between BIS and GCS score in patients with traumatic brain injury.

Why is it important?

In this study, a significant correlation existed between GCS and BIS. This finding suggests that BIS may be used for assessing GCS in patients with traumatic brain injury. However, the scatters of BIS values for any GCS level may limit the BIS in predicting GCS accurately.
