Bispectal Index (BIS) correlates with Ramsay and Cook Sedation Scores in intensive care unit patients

It is well known that the administration of sedation and analgesia constitute an inseparable section of the therapeutic approach of patients of the ICU. The follow-up and evaluation of the level of sedation has been considered indispensable, both for obtaining the desirable clinical objectives and, also, to avoid clinical complications. In an effort of creating a stable and objective system of evaluation of the level of sedation, we used various methods, the known scales and, recently the Bispectral Index (BIS) which constitutes a variable modification, a variant of the EEG. The aim of this study was to investigate the probable correlation between BIS and the Ramsay and Cook scales.
