Types of Medical Gauze and Telfa Dressings
How to Choose Medical Gauze
Medical gauze is a light material intended for post-surgical wound
applications or deep wound healing. In this introduction, we will
concentrate only on sterile gauze. Many medical gauze applications are
for direct wound placement and maintaining a sterile environment is
paramount for healthy, uninhibited healing. The gauze dressings can be
medicated or impregnated with antiseptic or made for wound debridement
-- specifically in cases where the wound is large and the incidence of
necrotic tissue may be present. The two general categories of gauze are
made from woven and non-woven materials.
- Woven Gauze: typically means that the gauze contains layers of woven cotton layered together into multiple ply sheets.
- Non-Woven Gauze: Non-woven gauze is usually synthetic material made
to look like a woven dressing yet maintain the same aeration ability.
Non-woven dressings are usually non-adhering. They will not leave residue, because they are synthetic and non-fibrous. They are like a film and make it more comfortable during the removal process. Many have a weave-like pattern to prevent pooling of exudate as well as having a perforation to allow a secondary dressing to absorb. They can be both dry and wet, meaning they may just be a sterile, dry contact layer, or they are impregnated with petrolatum, antiseptic, or another 'wet' substance to speed healing and kill bacterial.
Petrolatum: - Maintains a wet healing wound environment.
Saline Dressing: - Good for heavy exudate as the saline heightens rate of moisture wicking.
Hydrogel Gauze: - Maintains a moist environment and nurtures damaged vessels or burn areas.
How to Choose a Telfa Dressing
Telfa dressings are specialized gauze pads that can either be used
for primary or secondary woundcare applications. These dressings have
specific qualities to give them unique advantages over regular gauze
pads. Telfa dressing is similar to regular gauze in that it is made of
cotton fabric. However, unlike regular gauze pads, there is a coating on
both sides of the dressing to keep the material from sticking to the
wound when placed directly on the wound opening. This non-adherent
dressing is made for treating lightly draining wounds. It comes in
variations that make it an all-in-one option, or as part of a layered
woundcare dressing treatment involving either a primary or secondary
dressing with a wrap to secure it to the skin.
