BACKGROUND: The main objective of the experiment was to demonstrate that the use of dressing made of calcium alginate paste containing silver ions, results in significant reduction of pain symptoms and clinical signs of infection. The experiment also highlights the ease of application and removal causing no pain. Many of the wounds and/or bedsores that we normally handle are of small size, such as undermining and/or fistulas; sometimes these are wounds occurring in body areas that are so difficult to manage that they cannot be properly and effectively taken care of with the medications normally in use.
METHODS: The device testing was carried out on a sample of 70 patients with small size wounds, with obvious signs of critical colonization/local infection both in the acute and chronic phases. The patients had small wounds in acute and chronic phase, some with fistulas and/or undermining, obvious signs of critical colonization/local infection, felt pain and had difficulty in the use and application of advanced technology dressings (cavity/tape).
RESULTS: After the analysis of the data collected from all patients, it was concluded that: 1) the surrounding skin showed no more inflammation signs: erythema and edema disappeared; 2) there was a pain reduction without taking systemic pain medication; pain relief was immediate, already after the first dressing change (from an average value with rating scale VAS 7 to an average of VAS 2; 3) good control of bioburden and exudate diminished odor. The presence of odor is one of the most important concerns, after pain, for the patient.
CONCLUSIONS: We have shown that the use of this type of paste allows accurate medication of all those small wounds which, however, have undermined areas and/or fistulas that cannot be reached with other types of dressings. The paste shapes and conforms in all the wound ravines, thus allowing close contact between silver ions and bacteria. Alginate allows exudate control by creating and maintaining the right degree of humidity. This quick response in pain reduction has improved not only the patients’ quality of life, but also their and their families’ social relation aspect.
