MEDIAM 210 NON ADHERENT STERILE WOUND DRESSING

Mediam® 210 Dressings is a sterile secondary dressing main usage for wounds with light to moderate exudates.  

It consist of a heavier gauge, highly absorbent inner pad encased between two layers of highly embossed polyethylene film. This film minimises adherence of dressing to the wound.

General Information – Wound Healing

Traditional methodology of wounds healing is by allowing the wound to dry out or by utilizing the wound fluid and witting the wound to assist healing.  

An exposed wound or a wound without a moisture retaining dressing can dehydrate and form a scab. The result is a loss of living cells. The scab blocks new skin cell movement across the surface of the wound. Instead of the new cells gliding across the top of the wound, the new cells must 'burrow' underneath the scab to find a moist surface over which to grow. This process consumes extra energy and the wound can take longer to heal.
An exposed wound also experiences a lower surface temperature so cells do not work efficiently and healing is slowed.

A traditional dressing such as gauze allows the wound to dry out. As a result, the dried wound fluid (exudate) often sticks to the dressing. When the dressing is removed, it is often stuck to the surface of the wound, tearing not only the scab and dried fluid but also the new cells that are trying to heal the wound underneath the scab.

"Moist Wound Healing" is the name given to the process of controlling the wound environment to enhance the healing through the use of moisture. All body cells must have moisture to function effectively. Cells involved in wound healing function faster and more efficiently in a moist wound environment.

In 1962, George Winter discovered that a wound under an occlusive (blocking) dressing healed twice as fast compared to one that was allowed to develop a scab. This was to become the foundation for the concept of moist wound healing and the science of modern wound management.

A moist wound environment is provided through special dressings, which allow cells to be bathed in wound fluid so that they do not dry out and form a scab. This makes the epithelial cells migrate across the surface of the wound rather than underneath the scab. The retained wound fluid provides nutrients and growth factors to assist with healing. There are also white blood cells present in the fluid to help prevent infection. Nerve endings are bathed in wound fluid helping to reduce pain as nerve cells are stimulated in a dry environment.
