The efficacy of transcutaneous electrical nerve stimulation (TENS) in relieving postoperative pain has been assessed by means of a prospective randomized controlled trial in 62 male patients undergoing unilateral inguinal herniorrhaphy. Thirty-four patients received TENS and 28 patients received sham TENS for 48 h after the operation. Pain was assessed by means of linear analogue pain scales, analgesic requirements and peak expiratory flow readings. We were unable to detect any significant differences in these variables when the two groups were compared. These results do not support the use of TENS.
通过一项前瞻性随机对照试验，对62例接受单侧腹股沟疝修补术的男性患者进行了经皮电刺激神经疗法（TENS）缓解术后疼痛疗效的评估。34例患者接受TENS治疗，28例患者在术后接受48小时的假TENS治疗。通过线性模拟疼痛量表、镇痛药物需求量和呼气峰值流量读数对疼痛进行评估。比较两组时，我们未能在这些变量中检测到任何显著差异。这些结果不支持使用TENS。
