Endotracheal tubes Ī 2015 systematic review concluded that the limited evidence available indicates that using silver-coated endotracheal breathing tubes reduces the risk of contracting ventilator-associated pneumonia (VAP), especially during the initial days of utilisation. However, silver-containing dressings may cause staining, and in some cases tingling sensations as well. Ī number of wound dressings containing silver as an anti-bacterial have been cleared by the U.S.
A 2018 Cochrane review found that silver-containing dressings may increase the probability of healing for venous leg ulcers. Dressings ĭespite its widespread use, there is only mixed evidence that silver in dressings has any benefit. The US Food and Drug Administration (FDA) approved a number of topical preparations of silver sulfadiazine for treatment of second-degree and third-degree burns. It is on the World Health Organization's List of Essential Medicines. However systemic reviews in 2014, 20 concluded that more modern treatments, both with and without silver, show better results for wound healing and infection-prevention than silver sulfadiazine, and therefore SSD is no longer generally recommended. It was discovered in the 1960s, and was the standard topical antimicrobial for burn wounds for decades.

Silver sulfadiazine (SSD) is a topical antibiotic used in partial thickness and full thickness burns to prevent infection. Thus dead bacteria may be the source of silver that may kill additional bacteria. Silver, used as a topical antiseptic, is incorporated by bacteria it kills. The antibacterial action of electrodes coated with silver nanostructures is greatly improved in the presence of an electric field. Applying an electric current across silver electrodes enhances antibiotic action at the anode, likely due to the release of silver into the bacterial culture. The antibacterial action of silver has long been known to be enhanced by the presence of an electric field. ) to irreversibly damage key enzyme systems in the cell membranes of pathogens. The effectiveness of silver compounds as an antiseptic is based on the ability of the biologically active silver ion ( Ag + The antibacterial action of silver is dependent on the silver ion. Silver and most silver compounds have an oligodynamic effect and are toxic for bacteria, algae, and fungi in vitro. Alternative medicine products such as colloidal silver are not safe or effective. Silver generally has low toxicity, and minimal risk is expected when silver is used in approved medical applications. There is tentative evidence that using silver-alloy indwelling catheters for short-term catheterizing will reduce the risk of catheter-acquired urinary tract infections. The limited evidence available shows that silver coatings on endotracheal breathing tubes may reduce the incidence of ventilator-associated pneumonia. Wound dressings containing silver sulfadiazine or silver nanomaterials may be used to treat external infections. The medical uses of silver include its use in wound dressings, creams, and as an antibiotic coating on medical devices.
