| Question | Answer |
| purpose of surgical dressings | cushion/protection, absorption, drainage, aid debridement, support, splint, immobolise, aid haemostasis, enhance comfort, apperance, maintain moist environment |
| groups of dressings | primary - directly over wound secondary - placed over primary dressing |
| why put dressings on? | healing at optimum rate wound remains: moist, free from infection, slough, toxins, fibres, ideal temp, undisturbed dressing changes, ideal PH |
| wound dressings for SSI prevention | cover all surgical incisions low adherence, protection, transparent to look for signs of infection, left in for 3-5 days , epithelial process by primary intention |
| Gauze dressings | woven and unwoven, inhibits bacterial penetration |
| alginate dressings | dry until they come in contact with wound,where they take up fluid, remove exudate, promote healing through growth of epidermis, gel formed from alginate helps stop wound from drying out |
| foams | nonadherent, nonocclusive, absorptive, hydrophillic, indications for pressure ulcers |
| hydrocolloids | moist healing environment, insulation, impermeable to bacteria, not recommended for heavy exudate, may cause trauma to fragile skin |
| hydrogels | absorb moisture, ideal moist healing environment |
| composites | single dressing, combining two or more products, may include bacterial absroptive layer, hydrocolloid, hydrogel. facilitate autolytic debridement, adhesive border, but not to be used on pressure ulcers, fragile skin |
| ideal surgical site dressing | allows post op inspection makes wound waterproof low adherence prevent further contamination prevent heat loss |
| questions to ask for what dressings to use? | what does the wound need? what does the products do? how well does the product work? what does the patient need? what is practical? |
| securing dressings consrider | allergies, movement, support |
