| Summary: | Water-filtered infrared A (wIRA), a special form of heat radiation with a high tissue penetration and with a low thermal load to the skin surface, is able, through thermal and non-thermal effects, to essentially improve even energetically specific factors of the wound healing. This has been proven by measurements.wIRA can considerably alleviate the pain and accelerate the wound healing or improve a stagnating wound healing and diminish an elevated wound secretion and inflammation both in acute wounds (prospective, randomised, controlled, double-blinded studies of the Surgical University Hospital Heidelberg after abdominal surgery, n=94, and of the Children Surgical Department Kassel in severely burned children, n=45) and in chronic wounds and in problem wounds (prospective, randomised, controlled study in Basel, n=40, and prospective study of the University Tromsø/Norway in Hillerød/Denmark with effortful thermographic follow-up, n=10, in both studies chronic venous lower leg ulcers) including infected wounds. A positive influence on the wound healing is particularly possible even without a disturbance of wound healing. In chronic wounds complete healings are achieved, which were not seen before.wIRA is contact-free, easily applied, without discomfort for the patient, with absent consumption of material and with a good effect in the depth, which is equivalent to the sun heat radiation on the earth in moderate climatic zones. The irradiation of the uncovered wound is carried out typically from a distance of approximately 25 cm with a wIRA radiator.Wound healing and resistance to infection (e.g. granulocyte function including antibacterial oxygen radical formation of the granulocytes) depend decisively on a sufficient energy supply (and on sufficient oxygen). The clinically good effect of wIRA on wounds and also on problem wounds and wound infections can be explained by the improvement of both the energy supply per time (increase of metabolic rate) and the oxygen supply (e.g. for the granulocyte function).
