Abstract

Purpose: The purpose of this study is to evaluate the effects of low-intensity direct current (LIDC) with electrode placement of negative poles at wound site on pressure ulcer healing. Subject: The subjects were elderly patients having a pressure ulcer (sacrum, 2 cases; thoracic supine, 2 cases; ilium, 1 case; greater trochanter, 1 case; lateral malleolus, 1 case), and healings of these ulcers had been retarded. The DESIGN-R of these ulcers were between 13 and 19. Methods: The negative electrode of silver chloride was inserted into the foam dressing on the wound surface, and the positive pole was attached on intact skin around the wound. Electrical stimulation (intensity: 80 µA; frequency: 2 Hz; pulse length: 250 msec; duration: 40 minutes) were administrated five times per week. On every treatment, opposite electrodes were shunted by electrical cable after the stimulation. Result: Size reductions were observed on all ulcers treated with LIDC and these ulcers were healed completely at 5 ~10 weeks after the beginning of LIDC stimulation. Conclusion: The pressure ulcer healings were promoted by negative LIDC stimulation. It is suggested that LIDC stimulation with consideration for electrical polarity could be effective for shortening of the pressure ulcer healing period.
