Comparison of bispectral index scores from the standard frontal sensor position with those from an alternative mandibular position
BackgroundThe standard bifrontal application of the bispectral index (BIS) sensor interferes with the operative field in neurosurgery and plastic surgery. The aim of this study was to compare the standard frontal BIS sensor position with an alternative position across the mandible.MethodsTwo BIS™ Qu...
