Study Notes
Wound Healing Overview
- All surgeries create a wound that typically heals by primary intention.
- Secondary intention healing is used for wounds that do not close properly, potentially taking weeks or months.
- Tertiary intention is planned delayed closure by a surgeon.
Phases of Wound Healing
- Hemostasis and Inflammation: Immediate response lasting a few days.
- Proliferation: Begins after a few days and lasts several weeks.
- Maturation: Starts around 2-3 weeks and can last several months; phases may overlap, and wounds can stall.
Local Factors Affecting Wound Healing
- Mechanism of injury
- Infection and edema
- Ischemia and necrotic tissue
- Radiation effects and malignancy
- Hypoxia and foreign bodies
Systemic Factors Affecting Wound Healing
- Age, nutrition, and obesity
- Trauma and stress responses
- Metabolic diseases and immunosuppression
- Connective tissue diseases and smoking
- Vasoconstriction
Wound Healing History and Physical Examination
- Duration of the wound (days, weeks, months)
- Associated findings: drainage, erythema, warmth
- Previous wounds and treatments in the same or other locations
- Comprehensive assessment to identify common causative factors
Key Steps in Wound Healing
- Assess tissue perfusion through ankle/brachial index; normal is 0.9 – 1.2.
- Identify and remove nonviable tissue; avoid surgical debridement in severe ischemia.
- Evaluate for infection; consider cultures or imaging for diagnosis.
- Manage edema with compression if perfusion is adequate.
- Maintain moisture balance in the wound bed.
- Optimize tissue growth with NPWT, HBOT, or growth factors.
- Ensure pain is well-controlled for better dressing compliance.
- Regular reassessment at every visit.
Chronic Wounds
- Chronic wounds often heal by secondary intention.
- Factors affecting chronic wounds overlap with those for primary intention.
- Common causes: pressure, venous insufficiency, arterial insufficiency, diabetes, and neuropathy.
Pressure Ulcers
- Localized skin and deep tissue injury from constant pressure due to impaired mobility.
- Reduced blood flow leads to necrosis and skin breakdown; common sites include sacrum, back, and heels.
- Affects 2.5 million patients yearly at a cost of $27 billion.
- Annual lawsuits: 17,000; pressure ulcers are a leading cause of wrongful death with 60,000 deaths associated annually.
Treatment of Pressure Ulcers
- Identify risk factors like immobility, moisture exposure, and nutritional deficits.
- Reposition immobile patients every two hours.
- Use pressure-relieving surfaces and maintain skin moisture.
- Ensure appropriate wound care.
Venous Ulcers
- Affect about 1% of Americans; 80% of lower extremity ulcers.
- Risk factors: previous leg injuries, DVT, obesity, and older age.
- Symptoms include pain, swelling, varicosities, and ulcers that are irregular and shallow.
- Standard treatment involves compression therapy and proper wound care.
Arterial Ulcers
- Present with severe pain, especially when the leg is elevated; "punched out" appearance is common.
- Associated with risk factors like smoking, hypertension, and diabetes.
- ABI is crucial for diagnosis; an ABI < 0.5 indicates severe disease.
- Treatment includes proper wound care and vascular surgery; avoid compression.
Diabetic Foot Ulcers (DFUs)
- Diabetic patients face a significantly higher risk of ulcers due to nerve dysfunction.
- Neuropathy presents symptoms affecting motor, sensory, and autonomic functions, leading to unrecognized trauma.
- Charcot foot can result from prolonged diabetes complications, leading to foot deformity.
- Treatment focuses on wound care, managing blood sugar levels, and avoiding trauma.
Lower Extremity Amputation
- Patients with diabetes are 10 times more likely to undergo amputation.
- Five-year survival rate post-diabetic amputation is 30%; high risk of contralateral amputation.
Generalized Wound Care
- Wound care pertains to managing chronic wound closure.
- Focus on treating the patient holistically; thorough assessment is essential.
Moist Wound Healing
- Preventing dry scab formation promotes quicker epithelization.
- Ideal wound care products maintain a moist environment, are painless, non-allergenic, and cost-effective.
Types of Wound Dressings
- Gauze, transparent films (Tegaderm), hydrocolloids, hydrogels, alginates, foam, collagen, iodine, and silver dressings.
