The pH of a wound is assessed using a hydrogel film which changes colour in dependence upon pH. Suitably, the hydrogel film incorporates an indicator, across substantially its entire extent so that the film may be used to monitor pH across a wound. Wound pH information may be used to facilitate selection of the appropriate treatment to which the wound should be subjected. Suitably, the hydrogel film is incorporated into a dressing.

Le pH d'une plaie est évalué au moyen d'un film d'hydrogel qui change de couleur en fonction du pH. Ledit film d'hydrogel incorpore, de manière appropriée, un indicateur, sur sensiblement la totalité de son étendue de sorte que ce film peut être utilisé pour surveiller le pH d'une plaie. Les informations de pH d'une plaie peuvent être utilisées pour faciliter la sélection du traitement approprié auquel la plaie sera soumise. Ce film hydrogel est incorporé dans un pansement.
