수술 중 체성감각유발전위감시에서 인터리브자극방식의 임상적 유용성

Abstract

Intraoperative somatosensory evoked potentials (SSEPs) play a role in reducing postoperative complication. The method of obtaining the SSEP of both upper and lower limbs includes not only a method obtained by serially stimulating each limb, but also an interleave method using auto-sequence. We retrospectively reviewed the clinical and intraoperative monitoring records of 15 patients who underwent both upper and lower limbs intraoperative SSEPs at our hospital from March to September 2020. We compared the amplitude, latency, and acquisition time of the results in each patient when stimulated in serial mode and interleave mode, respectively. Interleave mode stimulation showed no difference in latency, greater amplitude, and shorter acquisition time compared to serial mode stimulation. There were no postoperative complications in 15 patients who underwent intraoperative SSEPs with interleave mode stimulation. Interleave stimulation using auto-sequence can be a clinically useful method for monitoring intraoperative SSEPs of both upper and lower limbs.
