Debridement is used to remove necrotic tissue or foreign bodies from the wound. There are many methods for debridement, and different methods have different definitions and indications. Some methods may still be disapproved under certain circumstances. Surgical and conservative sharps debridement are considered invasive methods due to the use of surgical instruments. Medical staff should follow their respective (doctors, nurses, specialist nurses, doctor assistants, etc.) practice scope and institution regulations to conduct clinical practice.
Debridement method:
There are currently 5 main non-selective and selective debridement methods, but many factors determine which method is best for your patient. Remember BEAMS, the acronym for 5 methods of debridement.
Biological debridement (Biological): Use maggots (larvae of Lucilia sericata) cultivated in a sterile environment to remove necrotic tissues, which can swallow and digest necrotic tissues and pathogenic microorganisms;
Enzymatic debridement (Enzymatic): topical application of enzyme-containing preparations to liquefy necrotic tissue. Enzymes can degrade the inactivated tissue in the wound matrix. The combination of antibacterial agents and collagenase will reduce the effect of enzymatic debridement. This method can be used in conjunction with surgical and instrumental debridement;
Autolytic debridement (Autolytic): The slowest method of debridement is the most commonly used method in long-term care institutions. The method does not cause pain. Using the body's own enzymes and the water retained by the dressing, the inactivated tissue is liquefied. Maintaining moisture balance is very important. The most commonly used dressings for autolytic debridement include hydrogels, hydrocolloids and transparent membrane dressings;
Mechanical debridement (Mechanical): Commonly used mechanical debridement methods include washing, hydrotherapy, and the use of wet to dry dressings. This method is cost-effective, but it can damage healthy tissue and is painful. Among them, wet-to-dry dressings have been replaced by advanced dressings and are not often used;
Surgical debridement (Surgical) and conservative instrument debridement: It is often performed by specially trained and experienced specialists, using surgical instruments, such as blades, curettes, scissors, and tweezers. The degree of debridement is determined by the type of tissue that needs to be removed.
