Abstract：Objective To explore the effects of different anesthesia methods on hemodynamics and neurophysiological monitoring intraoperative ( IONM) and postoperative cognitive function in patients in scoliosis correction surgery. Methods 100 patients undergoing scoliosis correction surgery were randomly divided into observation group and control group ( n=50 in each group) during January 2012 and June 2015 in our hospital. The observation group used Sevoflurane combined with Propofol anesthesia, the control group used Propofol total intravenous anesthesia. The vital signs, somatosensory evoked poten-tial ( SEP) , motor evoked potential ( MEP) , extubation time and postoperative cognitive function change in two groups were compared in different time periods:15 min ( T0 ) before induction, during intubation ( T1 ) , in 30 min ( T2 ) during operation 120 min (T3) during operation. Results There was no significant difference (P> 0. 05) between the two groups at the time of T0. In T1 , T2 , T3 time periods, the observation group's mean arterial pressure ( MAP) was lower than that of the control group, while the heart rate (HR) was faster than that of the control group (P<0. 05). There was no difference in SEP laten-cy between the two groups, but the amplitude of the observation group was smaller than that of the control group, and the re-covery time, extubation time and orientation recovery time of the observation group was less than that of the control group. The differences were statistically significant (P<0. 05). The SEP success rate was 100% in the two groups, and the MEP success rate was as high as 98%, 94%, but the intraoperative awareness was only 0, 2% with no statistically significant difference (P>0. 05). Conclusion The application of Propofol combined with Sevoflurane anesthesia has little impact on SEP, MEP and hemodynamics, and postoperative recovery is quick in scoliosis surgery.
