The Bispectral Index and Explicit Recall During the Intraoperative Wake-up Test for Scoliosis Surgery

Abstract

The relationship between bispectral index (BIS) and purposeful intraoperative patient movement is consistent with previous BIS utility studies. We conclude that BIS may be a useful clinical monitor for predicting patient movement to command during the intraoperative wake-up test, particularly when controlled hypotension is used and hemodynamic responses to emergence of anesthesia are blunted.
