chap 38 pt2 ques 8 Flashcards
types of wound
first
second
and third intention
wound w/ little tissue loss
edges are close together and aligned; usually
most rapid healing;
example
surgical wounds
first intention
what is an example of first intention wound
a surgical wound
A wound w tissue loss
severe laceration
not approximated
WOUND IS LEFT OPEN TO HEAL=LONGER HEALING TIME
GRANULATION
higher risk of infection
example; DECUBITUS (PRESSURE) OR LACERATION OR BURNS
second intention
known as delayed or secondary closure
third intention
occurs when there is delayed SUTURING of wound
wound are suture after the granulation tissue has begun
Example; Abdominal wound left open for drainage and then later closed
third intention
some factors that affect wound healing
age
nutrition
lifestyle
chronic illness
infection
medication
Peripheral vascular disease impairs what ?
impairs the blood flow, which impede healing
If A pt has Atherosclerosis and atrophy how does it affect the skin
reduce skin capillaries and blood flow to wound;
Protein,
adequate fluid intake,
vitamins A & C,
thiamine,
pyridoxine,
riboflavin,
zinc, iron, and copper
nutrition for wound healing
Regular exercise enhances blood circulation.
lifestyle
Use of steroids, immunosuppressants and other antiinflammatory drugs, anticoagulants, and antineoplastic agents interfere with healing
medication
haracterized by vascular changes of inflammation, and fluid collecting in the tissues
infection
Decreased oxygen and nutrients at the cellular level, disruptions in the normal metabolism of substances, each of which impede healing
such as diabetes
chronic illness
Why does smoking slow the healing process?
reduces function of hemoglobin in blood and oxygen perfusion at the wound site
