Can you explain the effect of silver cell in the pressure ulcer?

Antimicrobial. There are several wound products that contain silver. While each product has different indications depending on the character of the wound, the addition of silver is for the antimicrobial properties.
Silver Wound Care. Silver products are just one type of antimicrobial agent added to many different types of wound products. Others include iodine or methylene blue. The intent of any of these products is to decrease the bacterial burden in the wound. While many wound professionals use these products freely, the large studies do not show any advantage to using these products in the healing of wounds.
