Comparison of BIS and Ramsay score for evaluation of sedation with propofol in ICU

BACKGROUND: BIS has not been evaluated for sedation in ICU. We examined BIS for evaluation of sedation with propofol in ICU. METHODS: Eighteen male patients undergoing head and neck surgery (ASA-PS 1 x 2 and age<75 years) were randomly allocated to one of two groups receiving postoperative sedation with propofol in ICU. One group was monitored for sedation by BIS, and the other group by Ramsay score. RESULTS: There were no significant differences between the two groups in the total-dose of propofol, and recovery time. CONCLUSIONS: The use of BIS for sedation could not improve the management of postoperative sedation in ICU.
