One of the most common wound dressings is the simple gauze bandage. The goal of these products is to protect the affected area from dirt, bacteria and other outside organisms, while maintaining a moist environment and still allowing air to circulate.
Gauze has been used as a wound dressing for centuries, and continues to be the most readily available wound dressing in use today.
Gauze is Comprised of woven or nonwoven rayon, polyester or cotton. Non-woven dressings result in stronger pads with improved fluid wicking properties, compared to woven dressings. Gauze is available with or without adhesive border and may come in sheet, rope, rolls or squares.
Gauze can be non-impregnated and impregnated. Gauze May be impregnated with water, normal saline, hydrogel, or substances such as iodinated agents, petrolatum, zinc compounds, crystalline sodium chloride, aqueous saline, etc. Some impregnated gauzes have antimicrobial properties. They may also help prevent exposed tendons from dehydrating or adhering to the primary dressing.
Gauze is used to dress Partial or full-thickness wounds. Non impregnated gauze can be primary or secondary dressing while Impregnated gauze most often is used as a primary dressing.
Depending on the specific brand of gauze, it can manage minimal to heavy exudate.
Moist saline gauze may be used for mechanical debridement, filling dead space or cover the wound. Disadvantages - can damage granulation tissue on removal, may dehydrate the wound, permeable to fluid and bacteria. Impregnated gauze - is less adherent to wound bed or graft, keeps wound moist, not absorptive.
Non-impregnated gauze such as moist saline gauze (i.e., wet to dry dressings) have fallen out of favor for use on the chronic non-healing ulcer as it can damage delicate granulation tissue on removal and may dehydrate the wound. A moist gauze adheres the necrotic tissue as it dries out, allowing the necrotic tissue to be removed when the dressing is removed. However, this method of debridement is not universally liked, for a number of reasons. It is nonselective, meaning that the gauze may remove granulation tissue as well as necrotic tissue. The gauze often becomes embedded in dried exudate, making dressing removal painful.
Gauze is permeable to fluid and bacteria. Impregnated gauze is less adherent to wound bed or graft, keeps wound moist and does not absorb wound fluids.
Gauze dressings can be used on both infected and non-infected wounds of any size, shape, depth, or etiology.
The disadvantages of gauze are as follows:
Gauze may desiccate wounds with minimal exudate
When cut, woven gauze can leave fibers in the wound, acting as a foreign body and perpetuating inflammation
While these dressings are inexpensive, they require frequent changing and ultimately incur higher cost due to care time and the volume of product used
