The purpose of this study is to determine degree of correlation and predictive value between the monitoring parameters obtained with the bispectral index (BIS) and diagnostic electroencephalogram (EEG) in determining level of burst suppression during drug-induced coma.
When diagnostic EEG is utilized for monitoring level of burst suppression in drug-induced coma, far more information may be obtained than is necessary.
A study by Riker, Fraser, and Wilkins (2003) evaluated degree of correlation between parameters monitored with the BIS (SR and BIS value) with level of burst suppression/burst count on EEG.
Barbiturate and/or propofol dosing was compared with EEG state and BIS parameters including BIS value, SR, and burst count to determine predictive value of drag dosing for EEG state and level of burst suppression.
Establishing predictive value with additional research between BIS technology and diagnostic EEG for level of burst suppression in drug-induced coma would objectively test reliability and potentially generate additional evidence supporting BIS for monitoring level of burst suppression.
Workmen were switched temporarily from other duties to repair the burst mains but the high level of bursts
and consequent additional expense is one of a number of "adverse factors" which the group say will add to around pounds 300,000 in costs this year.
