Low bispectral index values in hydranencephaly.
Editor, We read with great interest the article by Prabhakar et al. [1] regarding the use of bispectral index (BIS) monitoring for an elective frontal craniotomy and fenestration in a 2-year-old boy with bilateral frontal lobe porencephalic cysts. During the procedure, the patient presented low preanaesthetic BIS values (39) that showed no significant change (between 30 and 40), despite a reduc...

To the Editor:—We read with great scientific interest the study of Vuyk et al. reporting three cases in which volunteers receiving combinations of propofol and midazolam remained responsive to verbal command although the Bispectral Index (BIS) values were at, or just above, 40, the area considered to be associated with adequate hypnosis for surgery (BIS, 40–60). Vuyk et al. note that the electr...
متن کاملLow bispectral index values in awake volunteers receiving a combination of propofol and midazolam.
THE Bispectral Index (BIS) is increasingly used to monitor the level of (un)consciousness during surgical anesthesia and conscious sedation. Generally, an intraoperative BIS of 40–60 is considered sufficient to maintain adequate hypnosis for surgery. Recently, a new version of the BIS monitor has been introduced: the BIS-XP (Aspect Medical Systems, Newton, MA). The BIS-XP is said to exhibit imp...

متن کاملDetermining entropy values equivalent to the bispectral index values during sevoflurane anaesthesia
INTRODUCTION We aimed to identify the entropy levels that would be equivalent to the bispectral index (BIS) levels in sevoflurane anaesthesia in patients who are to undergo elective lumbar disc surgery. MATERIAL AND METHODS Thirty cases in ASA groups I-II who underwent lumbar disc surgery under general anaesthesia were included in our study after obtaining the consent of the patients and Ethi...
