Abstract：Objective To analyze the factors related with intraoperative neurophysiological monitoring (IONM) in spine and spinal cord surgery under general anesthesia, in order to increase the effectiveness of IONM. Methods A retrospective study was performed on patients who received somatosensory-evoked potential (SEP) and motor-evoked potentials (MEP) in spine surgery under general anesthesia from Ju-ly, 2011 to January, 2016. Results Data from 104 patients were collected in which 18 cases had abnormal SEP and 17 cases had abnormal MEP. A single factor analysis indicated that abnormal SEP was related to concentration of inhalation anesthetic (CIA), hypothermia in peri-operative period (HTM), and type of anesthesia (χ2>6.219, P<0.05), whereas abnormal MEP was related to CIA, hypotension in periopera-tive period (HTN), and additional muscular relaxants (χ2>4.125, P<0.05). Logistic regression analysis indicated that abnormal SEP was relat-ed to CIA and HTM, whereas abnormal MEP was related to CIA and HTN (P<0.05). Conclusion CIA, HTM, and HTN were possible fac-tors related with IONM in spine surgery under general anesthesia.
