Our objective was to study the analgesic effect of acupoint pressure on postoperative pain in a controlled single-blind study. Forty patients undergoing knee arthroscopy in an ambulatory surgery unit in a university-affiliated hospital were randomized to receive either an active stimulation (AS) or a placebo stimulation (PS) 30 min after awakening from anesthesia. We stimulated 15 classical acupoints in the AS group, on the side contralateral to surgery, with a firm pressure and a gliding movement across the acupoint. In the PS group, 15 nonacupoints were subjected to light pressure in the same areas as the acupoints in the AS group. We assessed pain using a 100-mm visual analog scale (VAS) before sensory stimulation, after 30 and 60 min, and after 24 h. We recorded heart rate, systolic arterial pressure, and skin temperature before stimulation and after 30 and 60 min. We assessed skin blood flow with laser Doppler before stimulation and after 1 and 30 min. Sixty minutes and 24 h after AS, VAS pain scores were lower than in the placebo group (p < 0.05 and 0.0001, respectively). There were no significant changes in the autonomic variables. The results indicate that pressure on acupoints can decrease postoperative pain.
我们的目标是在一项对照单盲研究中，研究穴位按压对术后疼痛的镇痛效果。在一所大学附属医院的门诊手术单元接受膝关节镜检查的40例患者，在麻醉苏醒后30分钟被随机分为接受主动刺激（AS）或安慰剂刺激（PS）组。我们在AS组手术对侧刺激15个经典穴位，用力按压并在穴位上滑动。在PS组，在与AS组穴位相同的区域对15个非穴位施加轻压。我们在感觉刺激前、30分钟和60分钟后以及24小时后，使用100毫米视觉模拟量表（VAS）评估疼痛。我们记录刺激前、30分钟和60分钟后的心率、收缩压和皮肤温度。我们在刺激前、1分钟和30分钟后用激光多普勒评估皮肤血流。AS后60分钟和24小时，VAS疼痛评分低于安慰剂组（分别为p<0.05和0.0001）。自主变量无显著变化。结果表明，穴位按压可减轻术后疼痛。
