Wound and Ostomy Care Flashcards
What can wounds be classified with
Cause, apperance, depth, length of healing
What could be some underlying causes of wounds
Diabetic or arterial ULCER, venous insuffficiency, PRESSURE injury, SURGERY
What is an arterial ulcer
Poor blood flow
What is venous insufficiency ulcer
Can’t get FLUID back SEEPS out leg
What can the apperance of wounds be
open or closed
What are some open wounds
Abrasion, puncture, surgical
What can be closed wound
Soft tissue, deep tissue, stage one pressure injury
What are the different depths of wounds
Superfical, partial thickness, full thickness
What is skin layers are superficial
Only epidermis
What skin layers are partical thickness
epidermis and dermis
What skin layers are full thickness
all the way to the sub q layers or muscle and bone
What are the lengths of wound healing
Acute, chronic
What is acute wound healing
Seeing progress with the healing process
What is chronic healthin
Fails to progess to healing in a timely manar
What is a clean wound
LOW risk for infection, SURGICAL incision
What is a clean-contaminated wound
Surgery involved a system that contained BACTERIA
What type of wound would happen after a tonsillectomy, bladder surgery, dental work, or work on mucous membranes
Clean contaminated wound
What is a contaminated wound
HIGH risk for infection due to break in STERILE technique or from certain types of TRAUMA (particles, dirt)
What type of wound would be a ruptured appendix or gunshot wound
contaminated wound
What is an infected wound
Shows SIGNS of infection
What type of wound would be a wound that has redness, warmth, and drainage
Infected wound
What is a colonized wound
Organisms are present on the surface but
NO signs of infection
What type of wounds are MRSA and chronic wounds
colonized wounds
What are the intentions with the would healing process
Primary, secondary, tertiary
What is a primary intention
Create insicion and close it
What is a secondary intetion
Create insicion and leave it open
What type of intention would you use for an infected wound, or large wound
Secondary
What is tertiary intention
Delay closing until its clean
What type of intentsion would you use for a gunshot wound to the GI tract
tertaiary
What are the three phases of wound healing
inflammatroy, proliferatice, maturation
How long does the inflammatory phase last
3 days
What happens during the inflammatory phase
CLOT formation, DILATED vessels, CLEANING
What happens at the end of the inflammatory phase
clean and ready to repair
What during the proliferative phase
New GRANULATION tissue, ANGIOGENESIS
How long does the proliferative stage last
several weeks but can be shortened with a surgically closed wound (primary)
What does angiogensis do
COLLAGEN synthesis, CONTRACTION, EPITHELIALIZATION
What is the maturation phase
COLLAGEN deposites scar tissue
How long can the maturation phase take
up to a year
What happens in the maturation phase
Scar tissue is formed
How strong is scra tissue compared to normal tissue
80%
Is scar tissue more at risk for forming a pressure injury
yes
What are the factors that affect wound healing
O2, diabetes, nutrition, age, infection
Why does O2 affect wound healing
Chronic perfusion issues lead to impaired healing
Why does diabetes affect wound healing
Microbascular changes, THICKENING of vessels and OCCULSION of blood flow leads to less O2 which leads to delayed healing
Why does nutrition affect wound healing
Protein, VIT C, A, zinc, copper
What does age effect wound healing
Decreased INFLAMMATORY response and COLLAGEN synthesis
What causes wrinkles
Decreased collagen
Why does infection affect owund healing
Prolonged inflammatory phase, prevent epithelialization
What is dehiscence
Partial or complete separation of tissue layers during healing process, organ are still inside
What is evisceration
Total separation of tissuues allowing visceral organs to protrude
