Interactive wound dressings. A practical guide to their use in older patients.

Abstract

The properties of an ideal wound dressing do not change with the introduction of new types of wound dressing, but the range of effects on wound healing increases. The number of dressings available is enormous, and the choice between them is often bewildering. Because there is still no ideal dressing for all wound types, it is necessary to get to know a few well, and to avoid switching to new therapies solely on the basis of anecdotal reports. The adoption of novel dressings should be based on scientific evidence. At present, dressings are still chosen on the basis of local traditions and personal empirical experience, together with evidence from the few double-blind, placebo-controlled trials that have been performed. In the management of ulcers, a particular wound management plan should not be changed if the ulcer being treated is decreasing in size and the patient is comfortable. The dressing should be chosen with care. The type of chronic ulcer and its appearance, the amount of exudate and the presence or absence of pain all assist in the selection of an appropriate wound dressing product. Quality-of-life aspects are important. In the elderly, good quality of life may not necessarily require complete ulcer healing, although this is naturally desirable. Dressing changes should be minimised and the ulcer should be kept moist and the surrounding skin dry. The high cost of interactive dressings is a potential disadvantage of their use. However, if the wound can be re-dressed at longer intervals and if healing occurs more quickly, their use may be cost effective and associated with less pain and a better quality of life.
