Water-filtered infrared-A (wIRA) in acute and chronic wounds

17.12.2009
Water-filtered infrared-A (wIRA), as a special form of heat radiation with a high tissue penetration and a low thermal load to the skin surface, can improve the healing of acute and chronic wounds.

wIRA increases tissue temperature (+2.7°C at a tissue depth of 2 cm), tissue oxygen partial pressure (+32% at a tissue depth of 2 cm) and tissue perfusion. These three factors are decisive for a sufficient supply of tissue with energy and oxygen and consequently also for wound healing and infection defense. wIRA acts both by thermal (related to heat energy transfer) and thermic as well as by non-thermal and non-thermic effects.

In a bilingual review article, just published on December 16th, 2009, in the medical e-Journal "GMS Krankenhaushygiene Interdisziplinär" within Open Access-portal "German Medical Science" of the AWMF (Association of the Scientific Medical Societies in Germany), working mechanisms of wIRA and results of 6 scientific studies with wIRA are discussed.

wIRA can considerably alleviate pain (without any exception during 230 irradiations) with substantially less need for analgesics (52 - 69 % less in the groups with wIRA compared to the control groups). It also diminishes exudation and inflammation and can show positive immunomodulatory effects.
The overall evaluation of the effect of irradiation as well as the wound healing and the cosmetic result (assessed on visual analogue scales) were markedly better in the group with wIRA compared to the control group.

wIRA can advance wound healing or improve an impaired wound healing both in acute and in chronic wounds including infected wounds.

A median reduction of wound size of 90 % in severely burned children was already achieved after 9 days in the group with wIRA compared to 13 days in the control group.

With wIRA a wound closure and normalization of the thermographic image in otherwise recalcitrant chronic venous stasis ulcers was reached. The attached figure presents the successful healing process of a chronic venous stasis ulcer of the lower leg under therapy with wIRA. In a study with chronic venous stasis ulcers of the lower leg it lasted on average 18 days with wIRA versus 42 days without wIRA until complete wound closure.

After major abdominal surgery there was a trend in favor of the wIRA group to a lower rate of total wound infections (7 % versus 15 %) including late infections following discharge from hospital (0 % versus 8 %) and a trend towards a shorter postoperative hospital stay (9 versus 11 days).
Even the normal wound healing process can be improved with wIRA.
The mentioned effects have been proven in six prospective studies, with most of the effects having an evidence level of Ia/Ib.

wIRA represents a valuable therapy option and can generally be recommended for use in the treatment of acute as well as of chronic wounds.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
