Procedure - pg 172 box 7-13

• Prepare the patient and environment

• Hand hygiene

• Apply clean gloves

• Remove old dressing

• Assess wound

• Clean the wound

• Apply new gauze dressing

• Document

Medical asepsis

• Use clean gloves (sterile gloves not required unless wound is highly susceptible or ordered)

• Clean wound using standardized technique (inside to outside)

• Do not touch gauze that goes directly into the wound bed with bare hands

• Avoid contaminating the gauze or wound area by maintaining a clean field

• Properly dispose of soiled gauze and sanitize hands after procedure

• Impregnated gauze dressing into which materials such as petrolatum, hydrogel, saline, bismuth, or zinc have been incorporated.

• These dressings are designed to deliver medication to the wound or maintain a moist wound environment without adhering to the wound bed.

Advantages- pg 187

• Maintains a moist wound environment

• Non-adherent, reducing pain with dressing changes

• May deliver antimicrobial agents directly to wound bed

• Can be used under compression or in combination with other dressings

Disadvantages pg 187

• May require a secondary dressing to secure in place

• Can retain exudate, potentially leading to maceration if not monitored

• Needs frequent dressing changes depending on the level of drainage

Procedure pg 187-188

• Perform hand hygiene and apply gloves.

• Cleanse wound using appropriate wound cleansing protocol.

• Select and prepare impregnated gauze dressing.

• Place directly onto wound bed, ensuring full contact with the wound surface.

• Apply secondary dressing if required to manage exudate and maintain placement.

• Secure dressing with tape, wrap, or compression as indicated.

• Document dressing application, including product type, lot number (if applicable), and wound status.

Medical Asepsis pg 187-188

• Use clean technique unless otherwise directed (e.g., surgical or acute care settings may require sterile technique).

• Maintain non-touch technique when handling dressing that contacts the wound bed.

• Always dispose of old dressings properly and clean the surrounding periwound skin before application.

• A single layer of fluid saline-moistened gauze to a necrotic wound, covering with more gauze, and then allowing the dressing to dry 18-24 hours. As the dressing dehydrates, the gauze adheres to the wound bed, trapping wound exudate, foreign materal, and debris within the interstices. When the dressing is dry, it is torn away at a right angle from the wound surface, thus lifting away materal adhering to the gauze.

Advantages

• Provides nonselective mechanical debridement

• Low cost and readily available

• Can help remove necrotic tissue without specialized equipment

Disadvantages

• Nonselective — removes viable tissue along with necrotic tissue

• Can cause pain during removal

• May desiccate the wound bed, delaying healing

• Increases risk of infection due to frequent dressing changes

• Labor-intensive and may require analgesia

Procedure

• Don gloves and prepare supplies.

• Moisten coarse-mesh gauze with sterile saline.

• Lightly pack the wound, ensuring contact with all wound surfaces without overpacking.

• Cover with a dry secondary dressing.

• Leave in place until the dressing dries.

• Remove dressing dry to mechanically debride adherent tissue.

• Dispose of materials per infection control guidelines.

Medical Asepsis

• Perform hand hygiene before and after procedure.

• Use clean or sterile gloves as appropriate.

• Maintain a clean field for dressing supplies.

• Avoid contaminating the wound or supplies during application and removal.

• Dispose of soiled dressings in accordance with facility infection control protocols.

• Contraindicated for clean granulating wounds because the nonselective removal of tissue can damage healthy granulation tissue and delay healing .

2. Gauze (Woven and Unwoven), pg 147

• Avoid using as the primary dressing for wounds with exposed tendon, bone, or delicate structures unless appropriately moistened and monitored .

• Woven gauze may require more force to remove than non-woven gauze, potentially traumatizing the wound

  bed. Additionally, woven gauze may leave a residue

  or lint within the wound bed. The body may respond

  to this foreign material by forming a granuloma.

  Therefore, clinicians would be wise to use nonwoven

  gauze with a fine weave on wounds that are not 100%

  necrotic. If gauze dressings are allowed to dehydrate, that will adhere to wound bed, causing trauma upon removal.

3. Impregnated Gauze, pg 147

• There are timeswhen impregnated gauze dressings may be inappropriate. Xeroform gauze is impregnated with a combination of bismuth and petrolatum. Bismuth has mild antimicrobial properties and has been used prophylactically to prevent wound infection. However, bismuth is also cytotoxic to inflammatory cells and may be a sensitizing agent, that is, it may cause irritation, dermatitis, or an increased inflammatory response. Patients with venous insufficiency ulcers are particularly prone to such responses.20 Clinicians must weigh these poten-tially adverse responses against the potential benefitsof bismuth’s antimicrobial properties. Similarly, iodine-impregnated gauze packing strips are cytotoxic to human cells and only mildly antimicrobial.

Indications pg. 146:

• Gauze dressings can be used on both infected and uninfected wounds of any size, shape, depth, or etiology. Although gauze may not be the best choice of dressing, gauze dressings can be modified to be safe with any wound type. For example, if used on a nondraining or minimally draining wound, a topical agent can be applied to the wound bed to help main tain a moist wound environment or the gauze may be premoistened with normal saline. Alternatively, if used on a highly draining wound, additional layers can be used to aid in absorption. Gauze dressings can be used alone or in combination with topical antimicrobials, enzymes, growth factors, amorphous hydrogels, algi nates, semipermeable foams, or semipermeable films. There are several scenarios in which gauze is the dressing of choice. If a wound requires daily or more frequent dressing changes, gauze is the most economical choice. Therefore, gauze is commonly used on infected wounds or wounds being treated with enzymatic debriding agents. Because roll gauze dressings avoid adhesives, they may be the most appropriate secondary dressing for patients with fragile integument. Patients with large wounds or wounds in irregularly shaped areas may be best treated with gauze dressings because gauze is inexpensive and can easily be secured in place. Gauze packing strips (see Figure 7–6) are commonly used to prevent premature closure and wick away exudate in tunneling or undermining wounds.

2. Wet-to-Dry Dressings

Indications pg. 99:

• Wet-to-dry dressings are only indicated for wounds with 100% devitalized wound bed.

3. Impregnated Gauze Dressings

Indications pg. 147:

• Petrolatum-impregnated gauzes may be used as a wound contact layer on granulating wound beds in combination with a secondary gauze dressing. They can be used with or without a topical agent, such as an amorphous hydrogel or antimicrobial. Impregnated gauzes may also help prevent exposed tendons or tendon sheaths from dehydrating or adher ing to the primary dressing. Because petrolatum impregnated gauzes allow pain-free removal, these dressings are commonly used on burn wounds. Before being placed on the burn, a topical antimicrobial, such as silver sulfadiazine, is typically applied to these dress ings to treat an existing infection.19

G = Gauze (woven & nonwoven) → General use, versatile, absorbs

• It's versatile for primary/secondary use, packing, or securing other dressings; low cost; requires frequent changes; may traumatize wound bed on removal.

W = Wet-to-Dry → Wipe out debris, nonselective, for necrotic tissue

• For wounds with moderate to heavy necrosis, non-selective, not for clean granulating wounds

I = Impregnated Gauze → Infused with agents, keeps it moist, protects fragile tissue

• Low absorption- needs secondary dressing

• Ideal for burns, skin tears, donor sites, granulating/epithelializing wounds
