Study Notes
Wound Classification
- Superficial Wound: Trauma affects only the epidermis; often associated with sunburn.
- Partial-thickness Wound: Involves the epidermis and dermis; examples include skin tears and blisters.
- Full-thickness Wound: Extends through the epidermis and dermis into subcutaneous tissue.
- Subcutaneous Wound: Extends beyond the integumentary structures into underlying bone, muscle, or tendons.
Types of Wound Closure
- Primary Intention: Wound edges are reapproximated and closed using sutures, staples, or adhesives; commonly associated with surgical procedures.
- Secondary Intention: Wound heals independently without closure; typically occurs with nonviable margins or infections.
- Tertiary Intention: Wound is initially left open to resolve risk factors (e.g., edema or infection) before closure through primary intention.
Debridement Methods
- Sharp Debridement: Involves surgical instruments to remove devitalized tissue or debris; effective for necrotic tissue, infections, or cellulitis; performed by physical therapists in most states.
- Enzymatic Debridement: Utilizes topical agents for breaking down dead tissue.
- Autolytic Debridement: Engages the body’s own mechanisms for tissue removal using moisture-retentive dressings; effective but slower healing, not for infected wounds.
Advanced Treatments
- Hyperbaric Oxygen Therapy: Involves inhalation of oxygen; indicated for conditions like osteomyelitis and diabetic wounds; contraindicated in certain health conditions such as cancer and pregnancy.
Wound Dressings
- Alginates: Highly absorptive and moisture-retentive; ideal for partial or full-thickness wounds, especially infected ones, facilitating autolytic debridement.
- Hydrocolloids: Retains moisture for healing; suitable for partial or full-thickness wounds, not recommended for infected wounds.
- Hydrogels: Moisture-retentive, appropriate for superficial and partial-thickness wounds; not for heavily draining wounds.
- Transparent Film: Breathable but water and bacteria-proof; intended for superficial or partial thickness wounds with minimal drainage; not for infected wounds.
Important Facts
- Silver Dressings: Antimicrobial; effective on infected wounds like MRSA.
- Pressure Garments: Essential for burn healing and scar remodeling; to be worn for 12-18 months post-injury.
Types of Grafts
- Autograft: Tissue graft harvested from the same individual.
- Allograft: Graft derived from another human (e.g., cadaver tissue).
- Heterograft/Xenograft: Graft obtained from a different species (e.g., pig tissue).
Hydrofiber Dressings
- Hydrofiber Dressing: Alginate-like dressings activated by moisture, suited for wounds with high exudate.
- Usage Caution: Not appropriate for dry wounds.
