As we were interested in the use of bispectral index (BIS) monitoring during the application of acupuncture, we conducted a PubMed search on 31 July 2012 using the keywords ‘acupuncture’ and ‘bispectral index’. This yielded 23 articles reporting the use of BIS during evaluation of the effects of acupuncture. Except for the paper by Zheng et al recently published in this journal, none of these a...

BACKGROUND Unexpected awareness is a rare but well-described complication of general anesthesia that has received increased scientific and media attention in the past few years. Transformed electroencephalogram monitors, such as the Bispectral Index monitor, have been advocated as tools to prevent unexpected recall. METHODS The authors conducted a power analysis to estimate how many patients ...

We have compared fronto-central and bifrontal montages using a new EEG monitor, the Aspect A-1000. The monitor uses bispectral analysis to derive an index of anaesthetic depth, the bispectral index (BIS). We compared reliability, impedance and BIS for each montage. ECG electrodes placed in a bifrontal montage were more reliable than silver dome electrodes in a fronto-central montage and both ty...

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...

Editor—We read with great interest the recent article by Petrun and Kamenik regarding the use of a bispectral index (BIS) monitor as a guide to induce anaesthesia using an infusion technique with propofol compared with etomidate. This infusion technique is a plausible concept because of the BIS monitoring. Infusion techniques using propofol were performed many years ago, dating back to 1983–7 w...
