Abstract: ［Abstract］ Objective To investigate the effect of transcutaneous electrical nerve stimulation （TENS）on postoperative pain relief and reduction of analgesic requirement for elderly patients with frac? tures. Methods Sixty?five elderly patients（age>65 years old）who underwent orthopedic open surgery were enrolled and divided into two groups：TENS-treated group（TENS group，34 patients），and no TENS?treated group（control group，31 patients）. All patients underwent patient?controlled analgesia two days after surgery. Visual analogue scale（VAS）was used to assess postoperative analgesic requirements and pain intensity changes，and analgesic?related side effects were recorded. Results The consumption of fentanyl was lower in the TENS?treated group than in the non?TENS?treated group at 24 and 48 hours after surgery（all P values <0.05）. In the same time，the opioid?related side effects in TENS treatment group were significantly less than those in the non?TENS treatment group and the number of emergency medications was reduced. Conclusion TENS treatment can reduce postoperative analgesia in elderly patients with fractures，and can be used as an auxiliary treatment for postoperative analgesia.

摘要： ［摘要］ 目的 研究经皮神经电刺激（TENS）对于骨科老年患者手术后不同程度疼痛的治疗效果、能否减少术后镇痛药的使用量及其护理配合。方法 选择65 例接受骨科开放式手术的老年患者（年龄>65 岁）为研究对象并分成两组，接受TENS 治疗组（TENS 组，34 例），没有接受TENS 治疗组（对照组，31 例）。所有患者术后两天接受患者自控镇痛，使用视觉模拟评分（VAS）评估术后止痛药需求和疼痛强度变化，记录镇痛相关副作用的发生。结果 TENS 治疗组术后 24 小时和48 小时，芬太尼的消耗量低于非TENS 治疗组（P<0.05）。同样TENS 治疗组的阿片类药物相关副作用明显少于非 TENS 治疗组；应急用药次数减少。少数患者出现轻微皮肤症状。结论 应用 TENS 治疗加上相应适当的护理可以减少老年骨折患者术后镇痛需求，易操作、无创伤，可作为一辅助的减少患者疼痛的处理方法。
