Question | Answer |
what is the role of debridement in wound healing | reduces bioburden, control and potentially prevent wound infection, make wound bed visible, stimulates a pseudo acute wound |
when should debridement be contraindicated | poor perfusion, stable heel eschar, stable arterial eschar |
what is the difference between selective and non-selective debridement | selective is removal of nonviable tissue only, nonselective is removal of nonviable and viable tissue |
identify 4 types of debridement and give an example of each | autolysis (semiocclusive), chemical (enzyme), biosurgical., mechanical (wet to dry, irrigation) sharp (sterile scissors, forceps, or scalpel) |
when is Maggot therapy considered | as a last resort when the pt is not a surgical candidate |
name selective debridement methods | autolysis, enzymes, conservative sharp, maggot and ultrasonic mist |
name nonselective debridement methods | hydrotherapy, wet to dry gauze, surgical sharp |
when should Dakin's solution be discontinued | after 10 days |
identify general guidelines for selection of debridement | pt's goals, overall medical condition, urgency of debridement, status of the wound, skill level of the clinician, practice setting |
when is debridement indicated | if necrotic tissue (slough or eschar) is present, foreign bodies present, or when wound is infected |
explain autolytic debridement | naturally occurring process of wound healing WBC's and enzymes digest nonvital tissue, must have moist environment and nl abc count Honey, transparent film, polyacrylate & hydrogel are examples. Is NOT indicated for infected wound |
explain enzymatic debridement | selective, collagenase digest dead tissue can be used with local wound infection, d/c when wound bed clean, can use with other dsgs except iodine, PHMB, zinc and silver, ok for peripheral arterial ulcers and PU's |
explain biosurgical debridement | maggots- their excretions clean up the wound |
explain mechanical debridement | wet to dry, conservative sharp debridement, pulsatile lavage, irrigation,hydrotherapy, ultrasonic mist |
explain sharp debridement | surgical sharp (by MD only.; is nonselective) or conservative sharp (trained clinician, selective) |
explain high pressure wound irrigation- what equipment is needed | 19 g angiocatheter, 35ml syringe, 4-10 psi |
chemical debridement | sodium hypochlorite 0.0125% Dakin's solutionwill harm fibroblasts if over 0.0125% |
dakin's solution | typically used in heavily necrotic wounds with odor. effective against viruses, yeast and bacteria, odor control, debrides, short term, |
Ultrasound and MIST | Selective, traditional high frequency ultrasound lacks evidence to support but noncontact low frequency (MIST) and ultrasonic low frequency debridement (touches wound bed) does |
