infections acquired unrealted to healthcare treatment

|
|
in general refers to the removal of all foreign material from an object, usually done with water and mechanical scrubbing, possibly detergent

|
|
A sterile object remains sterile only when it is touched by__________
|
another sterile object
|
|
a sterile object is considered contaminated when___
|
out of range of vision or below waist line
|
|
the two types of wounds
|
those with loss of tissue and those without
|
|
acute wounds without tissue loss, and are easily pulled close together iwth sutures, clips, or steri-strips healing quickly usually within 14 days and scaring is minimal and risk of infection low
|
Primary Intention Healing
|
|
Tissue is lost, cavity left so the wound has to be left open and heal from the bottom up with granulation tissue
|
secondary intention healing
|
|
a wound in which the edges could be pulled together and closed with sutures or staples, but is purposely left open for 3-5 days due to excessive drainage, hemorrhage, or infection in the wound before it is closed
|
tertiary intention healing (delayed primary closure)
|
|
four types of wound drainage
|
serous, serosanginous, sanguinous, purulent
|
|
clear and watery drainage
|
serous
|
|
a pale red and watery type of drainage (has some red blood cells in it)
|
serosanginous
|
|
frank blood a thick type of drainage
|
sanguinous
|
|
liquified necrotic tissue, pus
|
purulent
|
|
4 types of wound complications
|
dehiscence, evisceration, fistula, enterocutaneous fistula
|
|
partial seperation of wound layers at the surface of the wound, most occur with abdominal wounds (after abdominal surgery it typically occurs around the 7th postoperative day if its going to) obese patients are especially risk because of the constant strain on the owund, plus fatty tissue heals poorley
|
dehiscence
|
|
_______drainage occurring more than 48 hours after a wound is closed may be a sign of impending dehiscence, if it occurs place the patient in LOW fowlers with knees bent to decrease the tension
|
serosanguinous
|
|
total separation of all layers of a wound with protrusion of abdominal organs a MEDICAL EMERGENCY
|
evisceration
|
|
an abnormal passageway connecting one epithelial surface with another
|
fistula
|
|
an abnormal passageway connection an epithelial surface with an organ once they form a stoma ("mouth" at surface of ski) they can only be healed by surgically removeing
|
enterocutaneous fistula
|
|
3 types of drains
|
penrose, jackson-pratt (JP), hemovac
|
|
for cleaning clean, non infected wounds use ____all of which deliver a force of __________
|
bulb syringe, piston syringe with no needle, or a gravity drip through IV tubing; a force of 2-4 pounds psi
|
|
for infected wounds a _____cc syringe with a ____guage needle works well and delivers about ____psi
|
35cc, 19 gauge needle, 8 lb psi
|
|
flow pressure should be between ___-___ fro non infected wounds
|
4-15 psi
|
|
force pressure of ___ for infected wounds

30 psi
|
|
___ solutions are used with low pressure cleaning of wounds
|
sterile
|
|
normal saline is used except when dressing or ointments incorporate_____
|
silver
|
|
irrigate from ____ to____
|
least to most contaminated (the wound is considered less contaminated then the surrounding skin)
|
|
two types of necrotic tissue that may appear in wounds
|
slough, eschar
|
|
loose, stringy, hydrated tissue that is usually yellow
|
slough
|
|
dehydrated, think, leathery tissue that is usually black
|
eschar
|
|
types of debridement
|
mechanical, autolytic, enzymatic, biological, surgical (sharp)
|
|
romoval of dead tissue by direct pressure or force, (wet-dry, pulsed low pressure irrigation, whirlpool)
|
mechanical debridement
|
|
covering the wound with a transparent occlusive synthetic dressing such as a transparent (tegaderm). It seals the wound, akeeps it moist and allows dead tissue to be "self-diegested" by the body
|
autolytic debridement
|
|
application of a topical enzyme ointment that breaks down dead tissue
|
enzymatic debridement
|
|
using sterile maggots
|
biological debridement
|

on an infected wound use what kind of dressing

|
wet-to-dry dressings should never be used on what kind of wound

clean granulating wounds that contain no dead tissue
|
|
how often should a wet-to-dry or wet to moist dressingbe changed
|
twice daily
|
|
an occlusive type dressing impermeable to water, water vapor, and oxygen, good for partial and full thickness wounds with minimum to moderate drainage (not very obsorbant and shouldnt' be applied to infected owunds)
|
hydrocolloid (duo-derm)
|
|
available as sheets, impregnated gauze or gels. they keep dry wounds moist and sooth and cool the wound (often used for thermal burns and painful sounds) needs to be changed daily

|
made of highly absorbant material manufactured from seaweed-can absorb up to 40 times their own weight in fluid (good for wounds which drain copiously change every 1/2 -3 ddays DONT use on dry wounds)
