Abstract:
Objective:To investigate the influence of electroacupuncture on auditory evoked potential index (AAI) during propofol sedation.Methods: According to propofol effect site concentration, 24 patients for operation were randomly allocated to group 1 (1.0 μg/mL), group 2 (1.5 μg/mL) and group 3 (2.0 μg/mL). Propofol was administered intravenously, points Hegu (LI4) and Neiguan (PC6) were electro-acupunctured, and changes in AAI were recorded.Results:AAI significantly rose in all groups during the initial several minutes after electro-acupuncture and significantly fell in group 2 at 20 min after electro-acupuncture(P＜0.05).Conclusion:AAI can sensitively reflect pain response during electro-acupuncture and electro-acupuncture can strengthen propofol sedation at its medium concentration.
