Sterile Technique and Infection Control: Professional wound care begins with proper hand hygiene and use of personal protective equipment including gloves, gowns, and eye protection when indicated. Maintain sterile technique when handling sterile supplies and dressings. Use sterile saline or appropriate wound cleansers rather than tap water for irrigation. Change gloves between dirty and clean procedures, and dispose of contaminated materials properly.
Wound Cleansing and Irrigation Protocols: Remove old dressings carefully, noting adherence and any tissue damage. Irrigate wounds with sufficient pressure to remove debris but not damage granulation tissue — typically 4-15 psi using an 18-gauge needle with 35ml syringe or commercial irrigation devices. Use gentle circular motions from center outward when cleaning surrounding skin. Avoid harsh antiseptics like hydrogen peroxide or povidone iodine in healing wounds as they can damage healthy tissue.
Debridement Techniques and Selection: Sharp debridement using scalpel or scissors provides immediate removal of necrotic tissue but requires skilled practitioners and appropriate patient selection. Enzymatic debridement uses topical agents to break down necrotic tissue gradually and is suitable for patients who cannot tolerate sharp debridement. Autolytic debridement uses the body's natural enzymes under occlusive dressings — slower but gentlest method. Mechanical debridement through wet-to-dry dressings is non-selective and can damage healthy tissue.
Advanced Dressing Selection and Application: Select dressings based on wound characteristics: hydrocolloids for light exudate and autolytic debridement, foams for moderate to heavy exudate with cushioning needs, alginates for heavy exudate with hemostatic properties, and hydrogels for dry wounds requiring moisture. Apply dressings with appropriate overlap onto intact skin, ensuring secure but not constrictive fixation.
Patient Education and Self-Care Training: Educate patients and caregivers on proper hand hygiene, dressing change techniques, and signs of infection or complications. Provide written instructions with diagrams when possible. Demonstrate proper disposal of contaminated materials and where to obtain supplies. Teach recognition of normal healing progression versus concerning changes.
