Use of the Lumiheal device in the treatment of contaminated wounds

Abstract

Observational study on patients with chronic wounds of lower limb colonized or critically colonized treated with biophotonic therapy. Ten patients with venous or inflammatory ulcers were enrolled. All enrolled patients were treated once a week with a double application of the therapy. The treatment period was 6 weeks, and a final assessment was performed at 12 weeks. The data collected were: evaluation of the bacterial load using the Moleculight system; and bacterial load with semi-quantitative method via swab according to Levine. Four types of bacteria were studied, Staphylococci, Pseudomonas, Enterococci, and Proteus. Ph measurement and evaluation of the Cutting and Harding score for infections. Results show a good performance in the control of bioburden and a reduction of clinical signs in 2 weeks. The secondary point was a reduction of pain and an improvement of perilesional tissue. The reduction of the area was batter in venous etiology wounds by close to 40% and a healing rate of 33%, good result but lower in inflammatory wounds. The authors hypothesize a marked activity on factors linked to local inflammation.
