Reduction of the acquisition time needed to obtain somatosensory evoked potentials by estimation of the required averaging sweep count by an algorithm

J Clin Monit ComputPublished Prospective methodological study

Authors' conclusion

The proposed algorithm allowed sweep count and acquisition time reduction in roughly 90% of all patients for mSEPs and in 70% of all patients for tSEPs.

Study context

Population
Patients undergoing spinal surgery with intraoperative SEP monitoring, Department of Neurosurgery
Participants
30 patients
Exposure
Algorithm-determined minimal sweep count vs standard 200 sweeps
  • mSEPsn = 15
  • tSEPsn = 15
Outcome
Median necessary sweep count to obtain reproducible evoked potentials (below 200)
