Week 1 Wound Interventions Irrigation Flashcards
what is irrigation
the use of fluid to remove loosely adherent cellular debris surface bacteria, exudate, dressing residue, and residual topical agents
why would be irrigate
keep a moist environment
enhance healing
facilitate debridement
irrigation if a perfect treatment for healing ___ wounds
granular
what are contraindications for irrigation
dont immerse or soak, don't use on skin grafts don't use on recent surgical incisions don't use on diabetic foot don't use on active profuse bleeding or dry gangrene
what are the four irrigation solution
sterile water
tap water
saline
wound cleanser
what is the benefit of saline and when is it best to use
can be made at home, and keep in fridge, but warm before use.
you must use what when using sterile water
silver dressing
who must we be cautious about when using tap water
immunocompromised
can we use saline with silver
no because it deactivates it
when can we use acetic acid pseudomonas
2-3 days after to control infection
when can we use chlorhexidine gluconate (Hibiclens)
on intact skin, or as a surgical scrub. not in open wounds
when can we use Dakin’s solution
this is sodium hypochlorite and bleach. can use on inanimate objects, never open wounds
when can we use chloramine T (chloazene)
heavily colonized or infected wounds.
when can we use hydrogen peroxide
cleanse around pin sites and sutures, not in open wounds
when can we use povidone - iodine (butadiene)
surgical scrub, or very short term acute new wound
with gentle irrigation and rinsing with a syringe or feeding tube, what is a safe and effective PSI
4-15
what PSI is low pressure capsules at
4-8, 10 max
what is low pressure lavage
irrigation without suction
what is the PSI and how does it work (talking about low pressure irrigation)
Jetox, 4-12 PSI and used wall O2 as the pressure. So there is a jet stream tip
what are the positives with whirlpool
cleanses, agitation, additives, temperature can range/vary, can treat large areas, and can exercise.
what are the negatives with whirlpool
risks infection (because aerosolizes and hard to sterilize), can injure tissues with the PSI, and can cause maceration. additives can be bad, and it is expensive and time consuming.
what are some contraindications for whirlpool
cleaning and granulating, edematous, draining or macerated wounds, bleeding, VI, multi-wound areas, uncontrolled seizures, B and B issues
what is PLWS
pulsed lavage with suction, which is where you have a pulsed jet of irrigation with suction. negative pressure. this can also stimulate granulation growth
what are the positives of PLWS
cleaning is disposable, you know the PSI, its sterile, the temp can range, nothing added, site specific, portable, disposable and easy clean up and few contraindications
what are the negatives of PLWS
expensive, aerosolized. risk in confined spaces of horizontal surfaces.
what are contraindications to PLWS
exposed tissues, body cavities facial wounds recent grafts or surgical sites active bleeding
