Your intraoperative date is admitted into evidence because: (select all that apply) You are monitoring a posterior fossa procedure with ABR and facial nerve EMG. Which anesthetic agent is not OK to use with respect to your monitoring? With significant changes in cervical and cortical SSEPs during intraoperative monitoring, adequate stimulation of the median nerve is indicated by: With significant changes in cervical and cortical SSEPs during intraoperative monitoring, adequate stimulation ...
