Inflammatory | initial increase in blood elements antibodies, electrolytes, plasma proteins and water flow out of the blood vessel and into the vascular space. |
heat, redness, swelling, pain and tissue dysfunction. Leukocytes engulf bacteria, fungi, viruses, and toxic proteins. New cells form. Blood clot dissolves the wound fills. Sides usually meet in 24-48 hrs. Seals the wound and protects it. | Inflammatory Phase |
Reconstruction | collagen formation occurs, usually from the 3-4th day to 2-3 weeks after initial injury |
Fibroblasts produce collagen, which adds tensile strength. glue-like protein. Collagen increases rapidly, post-op days 5-25. Irregular raised purplish immature scar. Foods high in vitamins A and C help. Dehiscence occurs during this phase. | Reconstruction Phase |
Maturation | from the 3rd week up to 2 years after the initial injury. Wound gains strength, scar formation, may develop a keloid (over growth of collagenous tissue) or hypertrophic scarring during this phase. |
Wounds heal at varying speeds. Internal wounds heal faster than external wounds. Keloids are elevated, rounded and firm; color ranges from red to pink to white. | Maturation Phase |
Primary intention | Wound edges are directly next to one another. Little tissue loss. Minimal scarring. Most surgical wounds heal by primary intention. Wound closure is performed with sutures, staples, or adhesive at the time of initial evaluation. |
Granulation | tissue and capillaries must extend from the edges inside the wound toward the center, this results in a broader scar |
Secondary intention | Epithelialization. Surgeon may pack a wound with gauze or use a drainage system to remove exudate. Granulation. Healing process is slow and can be prolonged. Wound care daily done daily. |
Tertiary Intention (Delayed primary closure) | The wound is initially cleaned, debrided and observed for a period of time (typically 4 or 5 days) before closure. The wound is purposely left open by placing dressing material in the wound to keep the edges apart. |
when does the nursing staff Assess the condition of wounds & dressing? | Every Shift |
Wound care documentation | Location. Size (length x width x depth). Drainage type and amount. Odor. Neurovascular (NV) status. Peripheral vascular status: depending on site of injury. |
Wound healing evaluation measures | Assess condition of the wound and dressing. Ask whether patient notes any discomfort during dressing change procedure; use pain scale to quantify level of pain. Inspect condition of dressings at least every shift. |
Potential nursing diagnoses for a patient requiring wound care | Potential for infection related to alteration in skin integrity. Alteration in comfort related to injury. Knowledge deficit related wound care |
What are the three types of wound healing? | Primary Intention. Secondary Intention. Tertiary (Delayed Primary) Intention |
Abscess | cavity containing pus and surrounded by inflamed tissue, formed as a result of pus from a localized infection |
Adhesion | band of scar tissue that binds together two anatomical surfaces normally separated; most commonly found in the abdomen |
Cellulitis | infection of the skin characterized by heat, pain, redness, and edema. |
Dehiscence | separation of a surgical incision or rupture of a wound closure |
Extravasations | passage or escape into the tissues; usually of blood, serum, or lymph. |
Hematoma | collection of extravasated blood trapped in the tissue or in an organ resulting from incomplete hemostasis after surgery. |
Wound bleeding may indicate? | a slipped suture, dislodged clot, coagulation problem, or trauma placed on blood vessels or tissue. |
Inspection of the wound and dressing aids in? | detecting an increase in drainage and color changes. |
S/S of Internal Bleeding | Patient will have increase thirst, restlessness, rapid, thready pulse, decreased blood pressure, decreased urinary output, and cool, clammy skin. |
Dressing may remain dry while the abdominal cavity collects blood. Abdomen will become rigid and distended. If not detected, hypovolemic shock can cause circulatory system collapse, causing death. | Internal Bleeding |
S/S of Dehiscence | Patient may say that something has "given way". May result after periods of sneezing, coughing, or vomiting. Evidence of new or increased serosanguineous drainage on the dressing is an important sign to assess. |
Dehiscence Management | Patient should remain in bed. Kept NPO. Told not to cough. Reassure patient. Place sterile dressing over area until physician evaluates the site. |
Evisceration Management | Patient is to remain in bed. Wound and contents should be covered up with warm, sterile saline dressings. Surgeon is notified immediately - this is a medical emergency. |
CDC labels: a wound is infected When? | it contains purulent (pus) drainage |
Purulent drainage has? | foul odor and is brown, yellow or green, depending on the pathogen |
Patient with an infected wound displays? | a fever, tenderness and pain at the wound site, edema, and an elevated WBC. |
Wound Infection management | Topical and systemic treatment ordered per pathogen and clinical symptoms. |
Factors that Impair Wound Healing | Extent of the Injury. Type of Injury. Age. Nutritional Status. Obesity. Impaired Oxygenation. Smoking. Drugs. Diabetes Mellitus. Radiation. Wound Stress |
Which wound complication is a surgical emergency? | Evisceration, notify surgeon immediately |
Surgical wounds generally heal better because? | they are aseptically created. They are usually covered by a dressing. |
Gauze | permits air (with impurities) to reach wound |
Semi-occlusive dressings | Permits oxygen but not air impurities to reach wound |
Occlusive dressings | does not allow air or oxygen |
thought to promote healing by keeping the wound moist yet sterile | Semi and Occlusive dressings |
What may be used to secure dressings? | Tape ties, bandages or cloth binders |
Inceision Dressing removal | Consult physician and agency policy. Medicate 30 min. prior if pain is expected. Assemble equipment needed. Sterile technique or standard precautions. Be careful not to disturb drains |
When are Dressings over closed wounds are usually removed? | by the third day |
Indication to use a dry dressing | Used when little exudate. Not used to debride a wound |
Indication to use wet to dry dressings | Need for increased absorption of exudate. dressing adheres to wound |
Wounds which call for Wet to dry Dressings | Abdominal evisceration, Dehiscence, Infected open wounds, Pressure ulcers, Diabetic foot ulcers |
What supplies do you need to do a dry sterile dressing change? | Gloves, gauze, tape, basin, NSS or SW, 30-60 ml syringe, pad |
Deep sutures are? | usually absorbable |
Sutures | threads of wire or other material composed of Silk, cotton, linen, nylon, Dacron or metal |
