Auricular acupuncture is a promising method for postoperative pain relief. However, there is no evidence for its use after ambulatory surgery. Our aim was to test whether auricular acupuncture is better than invasive needle control for complementary analgesia after ambulatory knee surgery.
One hundred and twenty patients undergoing ambulatory arthroscopic knee surgery under standardized general anesthesia were randomly assigned to receive auricular acupuncture or a control procedure. Fixed indwelling acupuncture needles were inserted before surgery and retained in situ until the following morning. Postoperative rescue analgesia was directed to achieve pain intensity less than 40 mm on a 100-mm visual analogue scale. The primary outcome measure was the postoperative requirement for ibuprofen between surgery and examination the following morning.
Intention-to-treat analysis showed that patients from the control group (n = 59) required more ibuprofen than patients from the auricular acupuncture group (n = 61): median (interquartile range) 600 (200-800) v. 200 (0-600) mg (p = 0.012). Pain intensity on a visual analogue scale was similar in both groups at all time points registered. The majority of patients in both groups believed that they had received true acupuncture and wanted to repeat it in future.
Auricular acupuncture reduced the requirement for ibuprofen after ambulatory knee surgery relative to an invasive needle control procedure.
耳针疗法是一种很有前景的术后疼痛缓解方法。然而，尚无证据表明其在门诊手术中的应用效果。我们的目的是测试在门诊膝关节手术后，耳针疗法在辅助镇痛方面是否优于侵入性针剂对照疗法。
120例在标准化全身麻醉下接受门诊关节镜膝关节手术的患者被随机分配接受耳针疗法或对照程序。在手术前插入固定的留置针，并保留至次日早晨。术后急救镇痛旨在使疼痛强度在100毫米视觉模拟量表上小于40毫米。主要结局指标是手术至次日早晨检查期间布洛芬的术后需求量。
意向性分析显示，对照组（n = 59）的患者比耳针疗法组（n = 61）的患者需要更多的布洛芬：中位数（四分位间距）为600（200 - 800）毫克对200（0 - 600）毫克（p = 0.012）。在所有记录的时间点，两组的视觉模拟量表疼痛强度相似。两组中的大多数患者都认为他们接受了真正的针灸治疗，并希望未来再次接受。
相对于侵入性针剂对照程序，耳针疗法降低了门诊膝关节手术后布洛芬的需求量。
