|
Definition
|
|
Term
When do you stop wound lavage? |
|
Definition
-absence of gross contamination -tissues begin to bubble and become pale white |
|
|
Term
What is sharp debridement? |
|
Definition
-use of scalpel and scissors to cut out devitalized tissue |
|
|
Term
How do you determine if tissue is devitalized or not? |
|
Definition
-color: black, grey, tellow, green, tan -texture: rubbery or dry -lack of blood supply -lacking tissue attachement -temp decreases |
|
|
Term
|
Definition
-evaluation of the depths of the wound using a sterile probe after lavage -very important with bite wounds |
|
|
Term

|
Definition
|
|
Term
IN which situations should we use a broad spectrum antibiotic? What about one that is simply efficacious against gram positives? |
|
Definition
-Broad specturm: bite wound, deep, or contaminated wound -Gram pos: simple, clean-contaminated laceration |
|
|
Term
For how long should we treat with antibiotics? |
|
Definition
|
|
Term
What are the indications for drain placement? |
|
Definition
-to drain avscess or fluid accumulation -foreign material or questionably viable tissue present -massive contamination is inevitable -obliteration of dead space -prevent accumulation of serum, blood, air |
|
|
Term
What is primary wound closure? |
|
Definition
-wound closed soon after damage |
|
|
Term
What is delayed primary wound closure? |
|
Definition
-wound closed 3-5 days after insult but before granulation tissue is present |

|
Definition
-wound is closed >5 dyas after insult with helathy granulation tissue resent |
|
|
Term
