INTRODUCTION The purpose of this study was to determine if noninvasive transcranial oxygen saturation (StcO2) and Bispectral Index (BIS) correlate with severe traumatic brain injury intensive care unit (ICU) outcomes. METHODS This is a prospective observational study. Values of intracranial pressure (ICP), mean arterial pressure (MAP), BIS, and StcO2 were recorded hourly for the first six, po...

Objective: The Cerebral State index (CSI) is a new index based on electroencephalogram to monitor depth of anesthesia. Transferring guidelines for titration of the Bispectral index (BIS) to the CSI depends on their compatibility. We compared the relationship between BIS and CSI values during propofol-remifentanil anesthesia. Methods: Forty one adult patients about to have open heart surgeries w...

The primary aim of this study was to test whether dexmedetomidine administration based on the bispectral index (BIS) monitoring caused a reduction in consumption of sevoflurane. Following Institutional Ethic Committee approval and written informed consent from all parents, fifty-four children undergoing sevoflurane anaesthesia randomly allocated to receive either dexmedetomidine (Group D) or sa...

Methods. One hundred and sixteen patients with traumatic complete SCI were grouped according to the time elapsed after the injury (,3 days and .9 months) and the level of injury (above T5 and below T5): acute high (AH, n1⁄425), chronic high (CH, n1⁄426), acute low (AL, n1⁄420), and chronic low (CL, n1⁄445). Twenty-five patients without SCI served as a control group. Bispectral index (BIS) respo...

To the Editor: We read with great interest the results of the largest Bispectral Index (BIS) monitoring study ever performed, which was published in the October 2012 issue of Anesthesiology.1 No significant difference in intraoperative awareness with explicit recall was detected between BIS and anesthetic concentration protocols (0.08 vs. 0.12%, P = 0.48) in an unselected surgical population of...

The usefulness of using the bispectral index (BIS) for monitoring during cardiopulmonary resuscitation (CPR) is not clearly understood. However, BIS has been a popular anesthetic monitoring device used during operations. The case presented is of a pregnant woman going into cardiac arrest due to an amniotic fluid embolism during a Cesarean section. CPR was performed, but neither the return of sp...

BACKGROUND Cerebral state index (CSI) has recently been introduced as an intra-operative monitor of anaesthetic depth. We compared the performance of the CSI to the bispectral index (BIS) in measuring depth of anaesthesia during target-controlled infusion (TCI) of propofol. METHODS Twenty Chinese patients undergoing general anaesthesia were recruited. CSI and BIS, and predicted effect-site co...

UNLABELLED Early and uneventful postoperative recovery of morbidly obese patients remains a challenge for anesthesiologists. It could be valuable to titrate the administration of inhaled anesthetic, such as sevoflurane, in morbid obese patients, in order to shorten emergence using bispectral index (BIS) monitoring. It would be a great advantage if BIS permitted a more rapid recovery and less co...

BACKGROUND The composite variability index (CVI), derived from the bispectral analysis (BIS), has been designed to detect nociception; however, there is no evidence that bilateral BIS and CVI show intrapatient reproducibility or variability. METHODS We conducted an observational study in patients who underwent for total knee arthroplasty. A BIS Bilateral Sensor was applied and continuously re...
