To evaluate the effectiveness of a transcutaneous electric nerve stimulation (TENS) device typically used for pain suppression (analgesia) during pressure injury (PI) healing, peripheral vascularization, and secondary pain in older adults with chronic PIs and cognitive impairment.
This pilot clinical trial followed patients from 6 nursing homes.
Twenty-two patients with PIs in the distal third of their lower limbs (7 men, 15 women) were included in this study. The control group completed standard wound care (SWC), whereas the experimental group received SWC and TENS. A total of 20 sessions were conducted for each group over 2 months, 3 times a week.
PI area, PI healing rate, blood flow, skin temperature, oxygen saturation, and level of pain at baseline and posttreatment.
Significant improvements were achieved in PI area (mean difference, 0.92; 95% confidence interval [CI], 0.15-1.67; P =.024), healing rate (3; 95% CI, 1-4.99; P =.009), skin temperature (1.82; 95% CI, 0.35-3.28; P =.021), and pain (1.44; 95% CI, 0.49-2.39; P =.008) in the experimental group, whereas none of the variables revealed a significant change in the control group.
The effect of local and spinal TENS combined with the SWC for PI produced a significant improvement in size, healing, skin temperature, and pain levels.
评估一种经皮电神经刺激（TENS）设备在患有慢性压疮（PI）和认知障碍的老年人压疮愈合、外周血管形成及继发性疼痛期间用于疼痛抑制（镇痛）的有效性。
这项试点临床试验对来自6家疗养院的患者进行了随访。
本研究纳入了22例下肢远端三分之一处患有压疮的患者（7名男性，15名女性）。对照组接受标准伤口护理（SWC），而实验组接受SWC和TENS。两组在2个月内共进行20次治疗，每周3次。
基线及治疗后的压疮面积、压疮愈合率、血流量、皮肤温度、血氧饱和度及疼痛程度。
实验组在压疮面积（平均差值，0.92；95%置信区间[CI]，0.15 - 1.67；P = 0.024）、愈合率（3；95% CI，1 - 4.99；P = 0.009）、皮肤温度（1.82；95% CI，0.35 - 3.28；P = 0.021）和疼痛（1.44；95% CI，0.49 - 2.39；P = 0.008）方面取得了显著改善，而对照组的所有变量均未显示出显著变化。
局部和脊髓TENS联合SWC对压疮的治疗在面积、愈合情况、皮肤温度和疼痛水平方面产生了显著改善。
