Falsely increased bispectral index values by convective air warming system during kidney transplantation

Falsely increased bispectral index values caused by the use of a forced-air-warming device.

Changes in bispectral index values during lumbar arthrodesis.

EDITOR: Several authors have reported sudden increases of the bispectral index values during different procedures such as endoscopic shoulder surgery [1], deep hypothermic circulatory arrest [2] or after using an upper-body blanket for warming [3]. In addition, spurious bispectral index values can be observed when the electromyogram activity of the bispectral index monitor reaches a value of 50...

Pitfall of bispectral index during intraoperative seizure

bispectral index (BIS) value while undergoing emergency kidney transplantation. Few reports have been made on intraoperative pitfall of BIS value associated with seizure. This case report suggests seizure should be taken into account as a reason for such brief fall of BIS, especially while under general anesthesia or in other specific cases in which clinical signs of seizure are unseen. (Korean...

Pitfall of bispectral index during intraoperative seizure -a case report-

We report a case of a 42-year-old male who developed generalized tonic-clonic seizure with sudden, brief decrease in bispectral index (BIS) value while undergoing emergency kidney transplantation. Few reports have been made on intraoperative pitfall of BIS value associated with seizure. This case report suggests seizure should be taken into account as a reason for such brief fall of BIS, especi...

Evaluation of the Adequacy of General Anesthesia in Cesarean Section by Bispectral Index

Background: Awareness and recall, though not common, are the major hazards of general anesthesia, especially in Cesarean section (C/S) because of the absence of benzodiazepine and opioids for a significant time during anesthesia. In this study, the Bispectral Index (BIS), end-tidal isoflurane, and hemodynamic parameters were examined to evaluate the depth of the routine general anesthetic techn...
