A prospective randomized double-blind study was undertaken to evaluate the efficacy of transcutaneous nerve stimulation (TNS) in relief of acute post-thoracotomy pain by comparing postoperative narcotic requirements in 22 patients having TNS and in 22 patients having sham electrical stimulation. All patients in both groups had intrathoracic malignancies. When TNS was used, 22.7% of the patients required no narcotics in the first 24 hr postoperatively. All patients having sham stimulation required postoperative narcotics.
进行了一项前瞻性随机双盲研究，通过比较22例接受经皮神经刺激（TNS）的患者和22例接受假电刺激的患者术后对麻醉剂的需求，来评估经皮神经刺激在缓解开胸术后急性疼痛方面的疗效。两组所有患者均患有胸内恶性肿瘤。使用TNS时，22.7%的患者在术后头24小时内不需要麻醉剂。所有接受假刺激的患者术后都需要使用麻醉剂。
