Wound Dressings (PTA)

Hydrocolloids anchored to intact skin surrounding wound
Hydrocolloids: INDICATIONS Partial & full-thickness wounds; Granular OR Necrotic wounds
Hydrocolloids: + ADVANTAGES Moist environment---Autolytic debridement---Protection from microbes---Moderate absorption---No 2° dressing needed---Waterproof surface
Hydrocolloids: - DISADVANTAGES Traumatizes surrounding intact skin when removed---Rolls in areas of excessive friction---Cannot be used on infected wounds
Hydrogels: INDICATIONS Superficial & Partial-thickness wounds (e.g. abrasions, blisters, pressure ulcers) that have minimal drainage
Hydrogels: +ADVANTAGES Moist environment---Autolytic debridement---Reduces pressure & pain---can be used as Coupling agent for US---Minimally adheres to wound
Hydrogels: - DISADVANTAGES Dressings can dehydrate---Not used if lots of drainage present---Requires 2° dressing
Foam Dressings hydrophilic @ wound contact surface (exudate absorbed) & hydrophobic on outer surface
Foam Dressing:INDICATIONS Protection for partial & full-thickness wounds with varying levels of exudate; can be used as 2° dressings over amorphous hydrogels
Foam Dressing: +ADVANTAGES Moist environment---Adhesive & Non-adhesive available---Prophylactic protection & cushioning---Autolytic debridement---Moderate absorption
Foam Dressing: -DISADVANTAGES Roll in areas of excessive friction---Removal of adhesive form may traumatize periwound---Wound inspection difficult (NOT transparent)
Transparent Film permeable to vapor & O2, but impermeable to bacteria and H20
Transparent Film: INDICATIONS Superficial wounds (scalds, abrasions, lacerations) or Partial-thickness wounds with minimal drainage
Transparent Film: +ADVANTAGES Moist environment---Autolytic debridement---Visualization---Resistant to shearing & friction---Cost-effective
Transparent Film: -DISADVANTAGES Periwound maceration (too much exudate)---Adhesive removal may traumatize periwound---NOT used on infected wounds
Gauze: INDICATIONS Infected & Non-infected---Wet-to-wet, Wet-to-moist, or Wet-to-dry debridement
Gauze: +ADVANTAGES Readily available & Cost effective---Used alone or in combo. with other dressings---Can modify # of layers (accommodate changing wound status)---Infected or uninfected wounds
Gauze: -DISADVANTAGES Adheres to wound bed---Highly permeable (requires frequent changing)---Increased infection rate
Alginates interaction of Calcium ions in the dressing & Sodium ions in the wound exudate; highly permeable & non-occlusive
Alginates: INDICATIONS Partial & full-thickness wounds such as pressure wounds OR venous insufficiency ulcers; infected wounds (lots of exudate)
Alginates: +ADVANTAGES High absorptive capacity---Autolytic debridement---Protection from microbes---Infected or uninfected wounds---Non-adhering to wound
Alginates: -DISADVANTAGES May need frequent changing (depending on exudate)---Requires 2° dressing---Cannot be used on wounds with exposed tendon, joint capsule, or bone
Occlusion ability of a dressing to transmit moisture, vapor, or gases from the wound bed to the atmosphere; impermeable
Most Occlusive Dressings-->Non-Occlusive Dressings (in order) 1) hydrocolloids 2) hydrogels 3) semi-permeable foam 4) semi-permeable film 5) impregnated gauze 6) alginates 7) traditional gauze
Most Moisture Retentive-->Least Moisture Retentive (in order) 1) alginates 2) semi-permeable foam 3) hydrocolloids 4) hydrogels 5) semi-permeable films
Types of Selective Debridement Sharp, Enzymatic, Autolytic
Types of Non-Selective Debridement Wet-to-dry dressings, Wound irrigation, Hydrotherapy
