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 July, 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 perioperative period (HTM), and type of anesthesia (χ2>6.219, P<0.05), whereas abnormal MEP was related to CIA, hypotension in perioperative period (HTN), and additional muscular relaxants (χ2>4.125, P<0.05). Logistic regression analysis indicated that abnormal SEP was related to CIA and HTM, whereas abnormal MEP was related to CIA and HTN (P<0.05). Conclusion CIA, HTM, and HTN were possible factors related with IONM in spine surgery under general anesthesia.
