What are the signs of an infected wound?
|
An infected wound is pussy, has necrotic dead tissue, and has debris in wound.
|
|
What are the 4 stages of healing?
|
The 4 stages of healing are inflammatory, debridement, re-epithelialization, and remodeling.
|
|
What are the 4 signs produced by histamine reaction?
|
The 4 signs produced by histamines are swelling, redness, heat, and associated pain.
|
|
What is debridement?
|
Debridement is when macrophages start to eat dead tissue and cleaning up the wound.
|
|
What is re-epithelialization?
|
Re-epithelialization is when new skin cells begin to grow across the granulation bed in order to form new skin growth.
|
|
What is remodeling?
|
Remodeling is the process of smoothing and thinning out scar tissue.
|
|
What is another name for remodeling?
|
Remodeling is also called maturation.
|
|
What are the 3 types of healing?
|
The 3 types of healing are first, second, and third intention.
|
|
Which intention of healing is surgical in nature?
|
First intention occurs in a clean or properly treated wound less than 6 hours.
|
|
What is another term for second intention healing?
|
Second intention healing can also be called natural healing occuring in wounds over 6 hours old.
|
|
What is third intention healing?
|
Third intention healing is a combination of second intention and first intention healing.
|
|
When will a wound begin to gain strength?
|
A wound will being to gain strength about 7 days after cause.
|
|
When will a wound gain maximum strength?
|
A wound will gain maximum strength at 14 days.
|
|
What are 4 common wound complications?
|
Common wound complications are infection, dehiscence, hematoma/seroma, and wound contracture.
|
|
What are signs of infection?
|
Signs of infection include redness, purulent discharge, swelling, and possible odor.
|
|
What is one of the most common causes of dehiscence?
|
One of the most common causes of dehiscence is infection, usually caused by improper home care.
|
|
What is a hematoma/seroma?
|
A hematoma is an accumulation of blood or serum below suture line.
|
|
What is used to take the pressure off hematomas?
|
Drains are used to take the pressure off hematomas and seromas.
|
|
What is wound contracture?
|
Wound contracture is the formation of scar tissue creating a lack of use in area.
|
|
What are the 6 purposes of suture material?
|
The purpose of suture material is to realign tissue edges, close dead speaces, tighten joints, strengthen weakened tissues, ligate bleeding vessels, and to hold tissues in place.
|
|
What are 7 ideal suture properties?
|
Ideal suture properties are strength, absorbability, easy to hyandle, minimal tissue reaction, monofilament, good knotting ability, and economical.
|
|
What are the 2 categories of suture?
|
Suture categories are absorbable and nonabsorbable.
|
|
