This study compared the effects of rocuronium reversed with sugammadex versus cisatracurium on TcMEP amplitude and recovery characteristics during thoracic and lumbar spine surgery.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st2\">\n<jats:title>Methods: <\/jats:title>\n<jats:p>A double-blinded, randomized controlled trial was conducted in 60 patients undergoing elective spine surgery. Participants were randomized to receive either rocuronium 0.6 mg\/kg with sugammadex reversal (Group R, <jats:italic>n<\/jats:italic> = 30) or cisatracurium 0.15 mg\/kg (Group C, <jats:italic>n<\/jats:italic> = 30). Primary outcomes included MEP amplitude and latency at 5, 10, 20, 30, and 60 min post-obtaining the fourth twitch in the train-of-four (TOF) sequence with a peripheral nerve stimulator. Secondary outcomes measured TOF recovery times and intraoperative adverse events. Data were presented as mean \u00b1 standard deviation. The normally distributed continuous variables were compared using Student\u2019s t-test, with <jats:italic>P<\/jats:italic> &lt; 0.05 considered statistically significant.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st3\">\n<jats:title>Results: <\/jats:title>\n<jats:p>Group R demonstrated significantly higher MEP amplitudes and shorter MEP latency at all time points from baseline till 30 min as compared to group C (<jats:italic>P<\/jats:italic> &lt; 0.05). TOF recovery was significantly faster in group R (<jats:italic>P<\/jats:italic> &lt; 0.001) as compared to group C. Group R had a higher incidence of nociception-induced movements (<jats:italic>P<\/jats:italic> = 0.076) and excessive field movements (<jats:italic>P<\/jats:italic> = 0.118), which was not statistically significant. The total propofol dosage in group R was significantly higher (<jats:italic>P<\/jats:italic> = 0.042) compared to group C. No postoperative neurological deficits occurred in either group.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st4\">\n<jats:title>Conclusion: <\/jats:title>\n<jats:p>At similar TOF ratios, sugammadex-facilitated reversal of rocuronium results in superior quality of MEP parameters, such as higher MEP amplitude and shorter MEP latency, with no significant difference in adverse movements compared to single-dose cisatracurium.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_765_2025","type":"journal-article","created":{"date-parts":[[2025,9,5]],"date-time":"2025-09-05T09:09:54Z","timestamp":1757063394000},"page":"384","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Effect
