The effect of transcutaneous electrical nerve stimulation (TENS) on the survival of a dorsal musculocutaneous flap was studied in the rat. Postoperative TENS treatment significantly increased the flap survival area in groups of rats receiving different modes of TENS. The flap survival area was up to 95% in the TENS-treated groups compared with 33-45% in the control groups. Repeated (3 days) high intensity (20 mA), high-frequency (80 Hz) TENS applied segmentally at the base of the flap was shown to be the most effective treatment in increasing the flap survival. Preoperative TENS did not increase flap survival area compared with untreated controls. It is concluded that postoperative TENS treatment markedly increases the experimental flap survival area and may be of clinical value for treatment of local ischaemia.
在大鼠身上研究了经皮电神经刺激（TENS）对背阔肌皮瓣存活的影响。术后TENS治疗显著增加了接受不同TENS模式的大鼠组皮瓣存活面积。与对照组的33%-45%相比，TENS治疗组的皮瓣存活面积高达95%。结果表明，在皮瓣基部进行重复（3天）的高强度（20 mA）、高频（80 Hz）节段性TENS治疗是增加皮瓣存活最有效的方法。与未治疗的对照组相比，术前TENS并未增加皮瓣存活面积。结论是，术后TENS治疗显著增加了实验性皮瓣存活面积，可能对治疗局部缺血具有临床价值。
