INTRODUCTION: Silver nanoparticle (AgNP)-containing dressings are used worldwide for the treatment of wounds; however, many studies have indicated that AgNPs are toxic to humans and cause cell death, primarily via apoptosis. OBJECTIVE: In this study, the investigators compare the apoptotic effects of various AgNP dressing materials, with the hypothesis that nanosilver would be less toxic than ionic silver. MATERIALS AND METHODS: For the in vivo experiments, Sprague-Dawley (SD) and streptozotocin (STZ)-induced diabetic rats were treated with 5 dressing materials: Aquacel Ag (product A, silver ion; ConvaTec, Berkshire, UK), Acticoat (product B, AgNP; Smith & Nephew, Fort Worth, TX), Medifoam Silver (product C, silver ion; Genewel Science Co Ltd, Seongnam, South Korea), PolyMem Silver (product D, AgNP; Ferris Mfg Corp, Fort Worth, TX), and Vaseline-impregnated dressing gauze (control; Unilever, London, UK)...

Burns are among the most common causes of injury in children. Several wound dressings are available to conservatively treat second-degree burns. Seventy-three children were treated with Aquacel Ag foam and Zn-hyaluronon gel to determine their effectiveness on partial thickness burns. We applied silver nitrate solution on 25% of patients for 24 hrs, then checked burn depth. If the burn was superficial second degree, we applied the dressing under study. All dressings were removed 6-7 days later. In the remaining children we used Aquacel Ag foam dressing with Zn-hyaluronon gel at first intervention...

The infection in burn wounds covered by biologic dressings leads to wound deepening and chronic wounds. The introduction of silver nanoparticles (AgNPs) into biologic dressings is a beneficial method to prevent wound infection and simultaneously promote wound healing. In this study, an AgNP-loaded silk fibroin (SF)/carboxymethylchitosan (CMC) composite sponge was fabricated. AgNPs with a mean diameter of 4.9 nm was synthesized in SF solution in situ. While CMC was incorporated and chemically crosslinked, SF was insolubilized by ethanol annealing...

Silver-impregnated dressings are increasingly preferred over silver sulfadiazine cream in the management of pediatric burns. An ideal burns dressing would provide a moist, sterile environment, discourage infection, and not require painful dressing changes. This study sought to determine whether silver sodium carboxymethyl cellulose (Aquacel Ag, ConvaTec, Greensboro, NC) dressing is a superior treatment to nanocrystalline silver-coated polyethylene (Acticoat, Smith & Nephew, London, United Kingdom) dressing in pediatric patients with partial thickness burns...

Various types of wound dressings have been designed for different purposes and functions. Controlling bacterial burden in a wound during the early phase is important for successful wound repair. Once bacterial burden is under control, the active promotion of wound healing is another important factor for efficient wound healing. This study investigated the potential of three silver-containing dressings, namely KoCarbonAg(®) , Aquacel(®) Ag and Acticoat 7, in reducing bacterial survival and promoting wound healing...

UNLABELLED: Many new antimicrobial dressings have been used for the treatment of or protection against wound infection since the early 1980s. There are many different wound dressings such as silver, povidone iodine, and chlorhexidine impregnated materials on the market today. Various manufacturers assert that their dressings are the most effective and therefore should be preferentially employed. However, it is difficult to find a study that clearly identifies the most effective antimicrobial wound dressing...

UNLABELLED: Silver-containing dressings are commonly used on healing wounds, including diabetic ulcers. Some studies have shown that dressing materials with silver have negative effects on wound healing, specifically, that the wound healing process is inhibited by deposited silver. Therefore, the authors treated wounds infected with methicillin-resistant Staphylococcus aureus (MRSA) in Sprague-Dawley (SD) rats and streptozotocin (STZ)-induced diabetic rats with silver dressings to evaluate the risks of silver...

Broad-spectrum antimicrobial agents, such as silver, are increasingly being formulated into medicated wound dressings in order to control colonization of wounds by opportunistic pathogens. Medicated wound dressings have been shown in-vitro to be effective against planktonic cultures, but in-vivo bacteria are likely to be present in biofilms, which makes their control and eradication more challenging. Recently, a functional wound dressing (AQUACEL(®) Ag+ Extra™ (AAg + E)) has been developed that in addition to silver contains two agents (ethylenediaminetetraacetic acid (EDTA) and benzethonium chloride (BC)) designed to disrupt biofilms...
