The effect of postoperative transcutaneous electrical nerve stimulation (TENS) was evaluated in 24 patients in two randomly selected groups who underwent thoracotomy. The patients in one group received TENS through periincisional electrodes, and the remaining patients were treated with sham stimulator setups. The stimulators remained in place for 48 hours after operation. Subjective pain scores, duration of stay in the recovery room, tolerance to chest physical therapy, complaints of nausea, time to end of mechanical ventilation, and narcotic requirements were evaluated. Patients in the TENS group had significantly lower pain scores during the first 24 hours postoperatively (p = 0.014), shorter recovery room stays (p = 0.013), and better tolerance of chest physical therapy on both day 1 (p = 0.018) and day 2 (p = 0.006). No respiratory complications occurred in either group.
对24例行开胸手术的患者进行了随机分组，评估术后经皮电刺激神经疗法（TENS）的效果。一组患者通过切口周围电极接受TENS治疗，其余患者采用假刺激器设置进行治疗。刺激器在术后放置48小时。评估了主观疼痛评分、在恢复室的停留时间、对胸部物理治疗的耐受性、恶心主诉、机械通气结束时间和麻醉药物需求量。TENS组患者术后前24小时的疼痛评分显著更低（p = 0.014），在恢复室的停留时间更短（p = 0.013），并且在第1天（p = 0.018）和第2天（p = 0.006）对胸部物理治疗的耐受性更好。两组均未发生呼吸并发症。
