摘要
作者对微量直流电刺激后能否促进表皮再生进行了实验研究。44只荷兰猪的脊柱两侧各切除直径20mm的全层皮肤,创缘固定,形成直径20mm的组织窗,创口的头尾两侧置电极。一侧伤口接通电流,另一侧不接通。观察10μA、30μA、50μA、和0μA直流电刺激下创口的愈合速度。结果显示:同一个体,直接电刺激侧表皮再生和创口愈合速度快于不直接电刺激侧,且阴极区快于阳极区;不直接电刺激侧创口愈合速度快于不刺激的创口。临床治疗厚断层皮片供区,获较好疗效。
An experimental study on Holland pigs was designed to evaluate the effect of direct current stimulation on the rate of epidermie regeneration. The 44 animals were divided into four groups, each of eleven animals and the stimulation levels were 10~uADC, 30~uADC, 50~uADC,0~uADC respectively. The results showed that the rate of regeneration of epidermic cell and wound healing was faster with the DC stimulation directly than indirectly, especially in the area of negative electrode and the rate of wound healing with the DC stimulation indirectly was faster than without DC stimulation. Proper applications direct current of appropriate intensity were definitely beneficial in the treatment of patient's donor site after removing a thick split-thickness skin graft.
