What is the healing process of a wound based on?
Pattern
Type of wound
Severity of wound
Overall condition
Time it takes to heal
Begins as soon as wound / injury occurs
Blood platelets adhere to the walls of the injured vessel, a clot begins to form
Fibrin in the clot begins to hold wounds together & bleeding subsides
hemostasis (Termination of bleeding)
Initial increase in the flow of blood elements (antibodies, electrolytes, plasma protein) & water out of the blood vessel into the vascular space
Repair cells to move toward the wound site & causes cardinal
S/s of inflammation
* erythema (redness)
* Heat
* Edema (swelling)
* Pain
* Tissue dysfunction
Cells in injured tissue migrate, divide, & form new cells w/in 24-48 hours
As this ends, new cells & capillaries refill in the wound from the underlying tissue to the skin surface
Inflammitory Phase of wounds
Myofibroblasts produce collagen (glue like protein strengthening wound tissue)
Collagen formation increases rapidly between postoperative days 5-25
Wound fills w/ granulation tissue & takes on the appearance of an irregular, raised, purplish, immature scar
* wound dehiscence most frequent in this pase
Reconstruction / proliferation phase of wounds
Wounds in which skin edges are closed together and little tissue is lost
* minimal scarring
Begins during inflammatory phase of healing in surgery
* usually in closure of wound
Primary Intention of wounds
When a wound must gradulate during healing
Occurs when skin edges are not close together (approximated), or when pus is formed
Some wounds develope purluent exudate (fluid, cells, or other that have been excreted from cells or blood through small pores/breaks in skin)
Slowly necrotized tissue decomposes & escapes , & the cavity begins to fill w/ granulation tissue, or soft, pink, fleshy projections that consist of capillaries surrounding by fibrous collagen
Secondary intention
Practitioner leaves contaminated wounds open & closes it later, after infection is controlled, by suturing two layers of granulation tissue together in the wound
* occurs when a wond becomes infected , opened, allowed to granulate, & and then sutured
Tertiary intention
What nutritional needs should be monitored in a pt w/ wounds?
Protein
Carbs
Fats
Vitamins
What can you do for a client who is unable to tolerate large meals or solid foods?
Eat small frequent meals
What food class helps promote wound repair?
Protein
* Meats
* Peanut butter
* Legumes
Vit A
* Dark leafy veg.
* Yellow/orange fruits & veg.
Vit C
* Strawberries
* Tomatoes
* Spinach
* Broccoli, califlower, cabbage
Zinc
* Fortified cereals
* Red meat
* sea food
What are some interventions for a pt w/ a wound?
Encourage fluid intake of 2000-2400mL in 24hrs
Monitor I/Os
* until stable (48-72hrs)
Balance rest & activity
Encourage to move one body part at a time
* To sit up, pt should roll to the side, use elbow as lever, & push into sitting position
If coughing occurs, apply pillow, rolled blanket, or palms of hands to incision area and apply pressure (Splinting)
Monitor for malnutrition, & chronic disease (HTN, DM, arthritis)
* these add stress to body & need ongoing monitoring
Watery plasma that is mostly clear, but may have some pink/yellow tinge to it
Thin, composed of serum portion of blood
Serous drainage
Thick
Yellow/green/tan/brown drainage
Indicates infection
Purulent drainage
Pale
Red, watery
Mixture of serous & sanguineous drainage
Thin
Can occur on the day of surgery
Serosanguineous
Bright red
Indicates active bleeding
Can occurs on day of surgery
Sanguineous
Closed drainage system that uses a bulb to provide the needed vacuum
Have wide, flat areas that must be brought through stab wound w/ great foce
Jackson-Pratt drainage device
Used after removal of gallbladder (via open cholecystectomy), the bile duct often is inflamed & edematous
* Drainage tube goes into duct to maintain free flow of bile until edema subsides
Long end of tube inserted through abdominal incision or through seperate surgical wound
Tube drains by gravity into closed drainage system
Collection bag emptied & measure Q shift
T-Tube drainage system
Used to treat acute wounds (traumatic wounds, flaps, & grafts) & chronic wounds
* Functions by applying negative pressure to wounds
Healing of wounds if facilitated by increased blood flow, improved/ increased fluid drainage, & enhance wound closure as pressure draws wounds together
Accelerated wound healing by promoting granulation tissue, collagen, fibroblasts, & inflammatory cells to close completely/ improve confition for skin graft
Negative pressure removes fluid from surrounding areas, thus reducing local edema & improving circulation
* After 3-4 days bacteria count drops
Wound-Vacuum-Assisted Closure (Wound vac)
Heart is not as effiecient as it should be
Ventricle is loaded with blood to the point where the heart muscle contraction becomes less efficient
Labs:
* CBC, MP
* Cardiac enzymes
* T3/T4, TSH
* C-reactive protein (If infection is suspected)
* B-type natrietic peptide (BNP)
* N-terminal pro b-type natiuretic peptide (NT-proBNP
Heart Failure
Often the choice for management of a wound w/ little exudate or drainage, such as abrasions and nondraining postoperative incisions
Keeps initial bleeding to a minimum & protects wounds from injury
Prevents introduction of bacteria, reduces discomfort, & speed healing
Prevents deeper tissues fromm drying out by keeping the wound surface moist
If dressing adheres to a wound, moisten dressing w/ sterile normal saline solution or sterile water before removing the gauze
Dry Dressing
Most appropriate for wounds that do not have significant amounts of ischemic or necrotic tissue or large amounts of drainage or exudate
Purpose is to keep wound bed moist or provide mechanical debridement
* Used NS & LR (Isotonic solutions)
Wet-to-dry dressing
