|
Term
| What are acute wounds and what are its characteristics? |
|
Definition
wounds that progress through the normal sequence of repair
Characteristics: wounds edges well approximated, decreased risk of infection |
|
|
Term
| What are chronic wounds and what are the characteristics? |
|
Definition
wounds that do not progress through the normal sequence of repair (anything that last longer than 6 weeks)
Characteristics: wound edges often not approximated, increased risk of infection, delayed healing process |
|
|
Term
| healing process includes... |
|
Definition
|
|
Term
| what are intentional wounds and what are the characteristics? |
|
Definition
results of planned invasive therapy or treatment
characteristics: clean wound edges, bleeding controlled, low risk for infection, wound healing is facilitated |
|
|
Term
| what are unintentional wounds and what are the characteristics? |
|
Definition
occur from unexpected trauma
characteristics:
wound edges are usually jagged, multiple trauma is common, bleeding is uncontrolled, high risk for infection, and prolonged healing time |
|
|
Term
| what are open wounds and what are the characteristics? |
|
Definition
the surface of the skin is broken
characteristics
potential tissue damage, increased risk of infection, risk for bleeding, risk for delayed wound healing |
|
|
Term
| what are closed wounds and what are the characteristics? |
|
Definition
skin is not broken (blunt trauma, spring, pressure ulcer)
characteristics:
low risk of infection |
|
|
Term
| What is primary wound care healing and what are the characteristics? |
|
Definition
occurs in wounds with minimal tissue loss
characteristics:
wound edges well approximated, wound edges seal together rapidly, decreased risk for scarring, decreased risk for infection |
|
|
Term
| What is secondary wound healing and what are the characteristics? |
|
Definition
healing occurs with tissue loss (actual tissue loss)
characteristics:
wound edges not approximated, openings fill with granulation tissue, later, epithelial cells grow over the granulation tissue, increased risk for infection, increased risk for scarring |
|
|
Term
| What is tertiary wound healing and what are the characteristics? |
|
Definition
occurs when there is a delay in the time between injury and the closure of the wound
characteristics:
wound surfaces granulate, scarring is common, high risk for infection |
|
|
Term
| what is partial-thickness healing and what are the characteristics? |
|
Definition
shallow wounds involving loss of the epidermis and possibly partial loss of the dermis
characteristics:
healing occurs by regeneration |
|
|
Term
| what are the components of wound healing in a partial- thickness wound? |
|
Definition
inflammatory response- normal for the 1st 24 hrs, redness, swelling, serious drainage, but only healthy for 1st 24hrs.
epithelial proliferation
reestablishment of epidermis |
|
|
Term
| what is the healing process of partial thickness healing? |
|
Definition
Inflammatory response- redness and swelling, moderate serous exudate, limited to the first 24 hours after injury
epithelial proliferation- redness and swelling
reestablishment of the epidermis- new epithelium is only a few cells thick, cells slowly reestablish normal thickness, new cells appear pink dry tissue |
