Intra-operative monitoring in scoliosis surgery with multi-pulse cortical stimuli and desflurane anesthesia

Abstract

This combination of anesthetic and stimulation protocols is efficacious for IOM during spinal cord surgery. Our findings support the use of desflurane for successful acquisition of MEPs during scoliois surgery as an alternative anesthetic regime.

A comparison of the effects of desflurane versus propofol on transcranial motor-evoked potentials in pediatric patients

“…The results of this study are consistent with previous studies showing the relative equivalence of desflurane and propofol [8,9]. One difference in this study was the use of desflurane or propofol as the sole anesthetic agent without an adjunct anesthetic such as nitrous oxide.…”

“…Studies of desflurane on MEPs, however, are limited. One group has reported MEPs with desflurane that are comparable to propofol [8,9]. Because of this limited information and especially since there is no data in the pediatric population, this retrospective study of the effect of desflurane on motorevoked potentials in children was undertaken.…”

Transcranial motor evoked potentials during anesthesia with desflurane versus propofol – A prospective randomized trial

“…The analysis confirmed results from studies in patients undergoing spinal surgery that indicated that tcMEPs are recordable independent of whether TIVA or inhalational agents were administered (Pechstein et al, 1998;Lo et al, 2004Lo et al, , 2006Hayashi et al, 2008Hayashi et al, , 2009. However, the primary goal of this study was to investigate the differences in tcMEP amplitudes depending on the choice of the anesthetic in CEA patients.…”

6p25 Deletion and Anesthetic Implications During Growing Rod Insertion for Early Onset Scoliosis

“…MEPs are more sensitive to the choice of anesthetic agents than SSEPs [24][25][26]. Anesthetic agents both inhaled and intravenous can depress SSEP and MEP with impairment of signal attainment.…”
