Interruption of bispectral index monitoring by nerve integrity monitoring during tympanoplasty -a case report-

Abstract

We report that intraoperative NIM-2 monitoring devices can interfere with bispectral index monitoring. A 45-year-old male with chronic otits media underwent tympanolasty under general anesthesia with NIM-2 monitoring and bispectral index monitoring at our institution. And then, bispectral index monitoring was severely interrupted by facial nerve monitoring. © the Korean Society of Anesthesiologists, 2013.
