Hydrocolloid dressings are a type of new wound dressing widely used in clinical practice. Such dressings can absorb small to moderate amounts of exudates and their airtightness can block the invasion of microorganisms, providing a moist environment for wound healing while also partially debriding the wound and promoting healing, reducing scar formation.
Application of the wet healing concept in clinical nursing work is very important, reflecting the value of professionalism and specialization. Hydrogel and hydrocolloid dressings are new wound dressings developed under the guidance of the wet healing principle, meeting the basic requirements of ideal dressings, such as protecting the wound, providing a suitable environment for wound healing, being easy to remove without damaging new tissue. The combined application of new dressings for clinical wound treatment has significant therapeutic effects, shortening healing time, relieving pain, and improving wound healing quality.
Hydrocolloid dressings have good moisture retention, can promote epithelial growth during incision healing, and are conducive to wound healing, unlike the traditional method of changing dressings, in which connective tissue proliferation replaces normal tissue and forms incision scars, and can effectively prevent scar formation in the clavicle section after surgery, thus satisfying the patient's desire for beauty.
The incidence of pressure ulcers in critically ill patients is higher than in ordinary patients due to reasons such as critical illness, advanced age, more bedridden, passive postures, circulatory failure, and frequent use of antibiotics. The sacral area is considered to be the most common site of pressure ulcers. It is necessary to correctly identify the staging of pressure ulcers, select different dressing products according to different stages, and adjust the treatment plan in a timely manner according to the wound condition.
Hydrocolloid dressings are bioactive and have strong airtightness. They are formed by processing elastic hydrogel, synthetic rubber, and viscous substances, and have a unique water gel. They provide a moist environment for the surface of the pressure ulcer, facilitate painless change, have strong absorption capacity, reduce the number of changes, and have a semi-permeable polyurethane backing that prevents bacteria and water from entering while allowing water vapor to pass through. They are semi-transparent and self-adhesive dressings that are easy to inspect the wound healing status and do not require secondary dressings. They provide the best conditions for pressure ulcer healing from the external environment, effectively avoiding the exposure of nerve endings, and reducing the damage caused by frequent dressing changes to the wound due to strong elasticity. They maintain the pH value of the incision skin in an acidic environment and have strong bactericidal effects against pathogenic bacteria. Compared with traditional dressings, hydrocolloid dressings can shorten the healing time of incisions.
