Study Notes
First Lines of Defense and Wound Types
- Skin serves as the primary line of defense against microorganisms.
- Closed wounds similar to bruises are known as contusions.
- Adequate oxygen and nutrients are necessary to maintain cell life and resist injury.
Ulcers and Pressure Injuries
- Pressure ulcers, also known as bedsores, develop due to prolonged skin pressure.
- Essential components for a normal body response to injury include proper blood flow and immune function.
- Resistance to injury can be influenced by factors like nutrition and hydration.
Healing Processes and Wound Management
- Normal healing is promoted when wounds are free from foreign material, allowing the body's natural processes to proceed unimpeded.
- Sharp object injuries are classified as lacerations or incisions.
- The inflammatory phase is the initial stage of wound healing, involving blood vessel constriction and clot formation.
Prevention and Treatment of Pressure Injuries
- To prevent pressure injuries, it is crucial to reposition patients regularly and relieve pressure from vulnerable areas.
- Maintaining higher humidity and using moisturizers helps keep skin hydrated, reducing friction and the risk of injury.
- Applying heat can enhance blood flow and alleviate pain in pressure injuries.
Dressings and Drainage Systems
- Hydrocolloid dressings are effective for maintaining moisture and promoting healing.
- When changing dressings, always follow aseptic techniques and assess the wound for any changes.
- Jackson-Pratt drains represent a closed drainage system often used following surgery.
Immediate Treatment Post-Injury
- Applying cold in the first 72 hours helps reduce swelling and numb pain.
- Factors affecting responses to hot and cold treatments include individual sensitivity and skin condition.
- Minimizing skin injury from friction or shearing is essential in preventing pressure injuries.
Assessment and Health History
- The first phase of wound healing focuses on hemostasis, ceasing blood loss.
- The proliferative phase involves forming new tissue and is fundamental for scar tissue development.
- Risks for pressure injury development include immobility, poor nutrition, and moisture.
- Stage 3 pressure injuries feature full-thickness skin loss affecting subcutaneous tissue but not underlying fascia.
Wound Assessment Considerations
- Health history should prioritize factors such as existing comorbidities, nutrition status, and medication effects on healing.
- Skin assessments should be conducted regularly in acute care settings to monitor any changes or signs of injury.
- Drainage assessment should consider color, consistency, and quantity to evaluate healing progress.
Additional Considerations
- Cold applications enhance comfort and reduce pain in the early stages of injury treatment.
- Cleansing skin routinely helps prevent infections and maintains skin integrity, particularly in at-risk patients.
