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 ...

During a median nerve preoperative study, a patient has discomfort at the wrist. Stimulation electrodes are 10 mm gold disk, stimulus intensity is 20 mA, and stimulus duration is 100 μsec. Which of the following would most likely reduce the patient's discomfort while maintaining adequate stimulation? - Decrease number of repetitions What is not an advantage of epidural recordings? - Absence of significant artifact The stimulation rate is determined by the - analysis time Somatosensory e...
