摘　　要：目的观察丙泊酚镇静时电针对听觉诱发电位指数(AAI)的影响。方法择期手术患者24例,根据丙泊酚效应室浓度随机分为Ⅰ组(1.0μg/mL)、Ⅱ组(1.5μg/mL)、Ⅲ组(2.0μg/mL)三组。静脉输入丙泊酚,电针合谷、内关穴,记录AAI变化。结果电针后最初几分钟均有显著性升高,Ⅱ组电针20min时有显著降低(P<0.05)。结论AAI能灵敏地反映电针针刺时引起的疼痛反应,在中等浓度丙泊酚镇静中电针可加强其镇静水平。Objective To investigate the influence of electroaeupuncture on auditory evoked potential index （AAI） during propofol sedation. Methods According to propofol effect-site concentration, 24 patients for elective 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） eleetroaeupunctured, and changes in AAI recorded. Results AAI signifieandy rose in all groups during the initial severn minutes after electroacupuncture and significantly fell in group 2 at 20 min after （P 〈 0.05）. Conclusion AAI can sensitively reflect pain response during electroaeupuncture. Electroacupuncture can strengthen propofol sedation at its medium concentration.
