Silver dressings for antimicrobial effect

Advanced wound care with silver dressings

Silver has a long and intriguing history as an antimicrobial in human healthcare. In wound dressings silver is used in various forms. The rate of onset of antimicrobial efficacy of silver has been demonstrated within 30 minutes of contact with clinically relevant bacteria.

Choosing the dressing on the basis of patient and wound needs


Silver dressings are available in different forms. The choice of dressing depends on the availability of the dressings in the clinical setting and of course on the needs of the wound and the patient, e.g. exudate level, wound depth, need for conformability, odor control, ease of removal and safety.

The Askina® Calgitrol® range is available in two different forms. Askina® Calgitrol® Ag+ is an antimicrobial silver dressing combined with reinforced fiber while Askina® Calgitrol® Paste is an amorphous silver alginate matrix in paste form. Each type of Askina® Calgitrol® is recommended for different wound characteristics.

Askina® Calgitrol® Paste conformable, not only for small tunnels and sinuses

Askina Calgitrol AG+, slightly-waved, hold by two hands in white examination gloves

Askina® Calgitrol® Ag+ for flat superficial highly exuding wounds

Askina® Calgitrol® Ag+

Askina® Calgitrol® Ag+ is a wound dressing that combines antimicrobial silver with strengthening cellulose fiber to manage wound infection and high exudate. The dressing promotes healing in a moist environment.  When applied, Askina® Calgitrol® Ag+ responds by forming a gel on contact with wound exudate. The gelling formation traps, locks in and kills the bacteria away from the wound bed. It contains encapsulated nanoparticles of ionic silver encrusted into the strengthening cellulose fiber. The nanoparticles act as a reservoir of ionic silver and are released gradually in contact with wound fluid to kill bacteria and microorganisms within the dressing.Under the supervision of a healthcare professional, Askina® Calgitrol® Ag+ antimicrobial wound dressings may be used for:All agesModerately to heavily exuding woundsChronic wounds, e. g. leg ulcers, pressure ulcers and diabetic ulcersSurgical wounds, e. g. post-operative, wounds left to heal by secondary intent and donor sitesTraumatic wounds, e. g. abrasions and lacerationsPartial thickness burnsIf required, the dressings can be used in conjunction with a suitable moisture-retaining secondary dressing to keep the product in place and/or under compression.

Askina® Calgitrol® Paste

Askina® Calgitrol® Paste is a sterile primary dressing consisting of an ionic silver alginate matrix in paste form, designed to treat chronic wounds which are infected or at high risk of infection.   The paste form, due to its water content, provides immediate availability of silver ions. Additionally, the ionic exchange with the wound exudate, delivers a sustained release of ionic silver to the wound bed.1   It is supplied sterile in a 15 g tube. The tube has a cannula to aid application of the paste into tunnels, sinuses, and all deep wounds. 2
