This study examined the effects of transcutaneous electrical nerve stimulation (TENS) on incisional pain caused by the procedure of cleaning and packing an abdominal surgical wound. Seventy-five subjects (mean age 56.9 years) were randomly assigned to one of three intervention groups: TENS, placebo-TENS, or no-treatment control. The appropriate experimental treatment was administered during the routine dressing change which took place two mornings after surgery. Using an 11-point, visual analogue pain scale, subjects described pain experienced during the dressing change. Subjects who received TENS reported a significantly lower level of pain after dressing change than did those subjects who received either placebo-TENS or no-treatment. Drug administration variables did not contribute significantly to level of reported pain.
本研究探讨了经皮电刺激神经疗法（TENS）对腹部手术伤口清创换药所致切口疼痛的影响。75名受试者（平均年龄56.9岁）被随机分为三个干预组之一：TENS组、安慰剂TENS组或无治疗对照组。在术后第二天上午进行的常规换药过程中给予相应的实验性治疗。使用11点视觉模拟疼痛量表，让受试者描述换药期间所经历的疼痛。接受TENS治疗的受试者在换药后报告的疼痛程度明显低于接受安慰剂TENS治疗或无治疗的受试者。药物给药变量对报告的疼痛程度没有显著影响。
