OBJECTIVE To determine the antimicrobial activity and efficacy of different formulations of novel bioxygenating hydrogel dressings (which deliver both iodine and oxygen into the wound) against various target organisms by means of an in vitro test system that more effectively mimics the conditions encountered when dressings are in contact with wounds. METHOD Three bioxygenating hydrogels were ...
OBJECTIVES To evaluate the antimicrobial activity of a new, transparent composite film dressing, whose adhesive contains chlorhexidine gluconate (CHG), against the native microflora present on human skin. METHODS CHG-containing adhesive film dressings and non-antimicrobial control film dressings were applied to the skin on the backs of healthy human volunteers without antiseptic preparation. ...
I t1960s t o la dmark tu ies stablished the concept of moist wound healing and heralded the development of modern dressings.1,2 However, despite the publication of a number of systematic reviews,3-6 there is na consensus on which dressings are most clinically and cast effective. This is due in part to the difficulty of conducting large randomised controlled trials (RCTs) as patients with wounds...
An ex vivo porcine skin explant biofilm model that preserves key properties of biofilm attached to skin at different levels of maturity (0-3 days) was used to assess the efficacy of commercially available antimicrobial dressings and topical treatments. Assays were also performed on the subpopulation of antibiotic tolerant biofilm generated by 24 hours of pre-treatment with gentamicin (120× mini...
BACKGROUND Silicone gel dressings decrease scar volume and soften hypertrophic tissue, allowing it to be more easily controlled by other methods. Although silicone does not appear to be an essential component of the treatment, nonsilicone dressings have been reported to cause no change in physical parameters during a 2-month treatment period. OBJECTIVE To compare silicone and nonsilicone gel ...
OBJECTIVE To test the usefulness of silver dressings in patients with skin ulcers in the healing phase after debridement. MATERIALS AND METHODS After randomly selected a group of 30 patients and divided them into three groups (A, B and C) according to the type and severity of the ulcer, we used respectively for each group antiseptics-free dressings, hydrofiber dressings with a low or a high c...
Chitosan oleate was previously proposed to encapsulate in nanocarriers some poorly soluble molecules aimed to wound therapy, such as the anti-infective silver sulfadiazine, and the antioxidant α tocopherol. Because nanocarriers need a suitable formulation to be administered to wounds, in the present paper, these previously developed nanocarriers were loaded into freeze dried dressings based on ...
