Accelerated wound healing has been an observed effect of low intensity direct current (LIDC) in the range of 200 microA to 800 microA, but present electrotherapeutic equipment has been less than optimal in providing this range of stimulation. A small and portable LIDC stimulator was specially constructed and used in a study of the effects of LIDC on wound healing rates among inpatients here. Thirty patients with indolent ulcers located either below the knee or in the sacral area were randomly assigned to the LIDC protocol or to more conventional wound therapy. The patients in each treatment group were matched by age, diagnosis, wound size, and wound etiology. Comparison revealed 1.5 to 2.5 times faster healing in those receiving LIDC, which was statistically significant. The wounds treated with LIDC required less debridement and the healed scars were more resilient. Additionally, no wound infections occurred and patients reported less discomfort at the wound site. Low intensity direct current appears to be a convenient, reproducible, and effective method for improved healing of chronic open wounds and warrants more widespread use in the clinical setting.
在200微安至800微安范围内，加速伤口愈合是低强度直流电（LIDC）已观察到的一种效果，但目前的电疗设备在提供该强度范围的刺激方面不尽人意。特制了一款小型便携式LIDC刺激器并将其用于一项关于LIDC对这里住院患者伤口愈合速度影响的研究。30例患有膝下或骶部慢性溃疡的患者被随机分配至LIDC治疗方案组或更传统的伤口治疗组。每个治疗组的患者在年龄、诊断、伤口大小和伤口病因方面进行了匹配。比较结果显示，接受LIDC治疗的患者伤口愈合速度快1.5至2.5倍，具有统计学意义。接受LIDC治疗的伤口所需清创较少，愈合后的瘢痕更有弹性。此外，未发生伤口感染，患者报告伤口部位的不适感减轻。低强度直流电似乎是促进慢性开放性伤口愈合的一种方便、可重复且有效的方法，值得在临床环境中更广泛地应用。
