|
Term
primary intention healing |
|
Definition
acute wounds without tissue loss, skin edges are approxamate and easily pulled together ( staples, sutures, steri-strips), heal in orderly and predictable fasion, all at once, usually 14 days, scaring minimal, risk of infection low |
|
|
Term
secondary intention healing |
|
Definition
tissue is lost, wound edges ca not be pulled together, heal from the bottum up with gradulation tissue, healing takes a long time, burns pressure ulcers, dermis never replaced and huge scar. new epithelial tissue covers gradual tissue |
|
|
Term
tertiary intention healing |
|
Definition
delayed primary closure a wound where the edges could be pulled together and be closed sutures or staples but need to remain open for 3-5 days due to excessive drainage, hemmorage, or infection in the wound before it is closed |

|
Definition
-serous- clear and watery -serosanginous- pale red and watery type of drainage ( some red blood cells in it) -sanguinous- drainage that is primarily composed of actual bright red, thick drainage, if amount of blood if huge then its called hemmorage. purulent- "pus" liquified nuercrotic tissue, usually not always indicates infection |

|
Definition
the intent is to gently wash away debris ( dead tissue) from the wound surface |
|
|
Term
what are the four rules of cleaning |
|
Definition
- sterile solutions are used with low pressure. Normally sterile saline is used when dressing ointments, but when the ointment has silver in t ( which is a bacterialcidal it will disrupt it ) so we use sterile water |
|
|
Term
irrigate or clean from the least to most contaminated part of the wound |
|
Definition
true; the wound is less contaminated than surrounding skin |
|
|
Term
flow pressure for non-infected wounds, pressure and equipment |

|
|
Term
three types of mechanical debridment |
|
Definition
-wet to dry dressing -pulsed low pressure ( requires special equipment -whirlpool treatment-not used alot now to rough for grandule tissue and pseudomas can ive in watery pipes |
|
|
Term
|
Definition
covering wound with transparent occlusion synthetic dressing such as tegaaderm or opt site. It seals the wound keeps it moist , and allows the dead tissue to be self absorbed by the body |
|
|
Term
|
Definition
topical enzyme ointment that eats away at dead tissue; acts slowly (SO CANT USE ON PATIENT WITH SEPSIS). they work in the presense of moisture, make sure wound is moist apply damp saline dressing if necessary -selective wont harm grandulane tissue as long asnot left on more than 24 hours |
|
|
Term
two types of chemical debridement |
|

|
Term
transparent film dressing |
|
Definition
either tegaderm op site is good for superficial wounds with little drainage not absorbant used fo autolytic debridement allows wound to be seen served as a secondary dressing over gauze |
|
|
Term
dry sterile dressing (DSD) |

Definition
sterile 4*4 gauze taped in place covers surgical incisions, keeps them clean, absorbs small amounts of drainage 24-48 hours lasts |
|
|
Term
dry gauze w/ topical ointment dressing |
|
Definition
used for infected wounds gauze absorbs drainage but not occlusive allows air to pass through. |
|
|
Term
when dry gauze is used to pack the wound |
|
Definition
you should pack light but full, to tight can prevent wound closure |
|
|
Term
moistend gauze ( wet-dry) |
|
Definition
not used alot any more, you put wet gauze in wound let it dry pull it out with dead tissue stuck to dry gauze it can harm grandule tissue and leave gauze debri in the wound |
|
|
Term
moistened gauze (wet-wet) |
|
Definition
do not let it dry out purpose is to keep wound hydrated |
|
|
Term
moistened gauze in general |
|
Definition
only be changes twice daily, make sure you maintain normal temp at wound surface most of the day because it reduces vasoconstrivtion, and enhances cellular activity, do not get intact skin around wound wet |
|
|
Term
|
Definition
duo-derm, available ad wafers in many forms, and as pastes and powders, they are an occlusive type dressing water resistant, and oxygen. good for partal and full thickness wounds with minimum to moderate drainage ( not very good absorbant), can be left on 3-5 days CAN NOT BE PUT ON INFECTED WOUNDS |
|
|
Term
|
Definition
available as sheets,impregnanted gauze, or gels. They keep dry wounds moist, soothe and cool. not absorbant, often used with therma burns and painful wounds. need to be held in place with secondary dressings and changed daily because the can hurt the peri-wound skin |

Definition
made up of highly absorbant material manufactored from seaweed, can absorb up to 40 times their own weight in fluid. good fro draining wounds change 2 1/2 to 3 days. BE AWARE NOT ALL HAVE BEEN TESTED ON KIDS< INFANTS |
|
|
Term
Negative Pressure Wound Therapy |
