What Is a Hydrogel Wound Dressing?
Wound dressings are wound dressings that cover sores, wounds, or other damage. The types of wound dressings are: 1. Passive dressings (traditional dressings), passively cover the wound and absorb exudates, providing limited protection for the wound. 2. Interactive dressings. There are various forms of interactions between the dressing and the wound, such as absorbing exudate and toxic substances and allowing gas exchange to create an ideal environment for healing; the barrier outer layer structure prevents Invasion of microorganisms in the environment to prevent cross infection of wounds. 3. Bioactive dressings (closed dressings).

- Wound dressings are wound dressings that cover sores, wounds, or other damage.
- Today, new dressings for wound care have undergone revolutionary changes compared to earlier days, and a variety of dressings with different properties are available for clinical nurses to choose from.
- In general, the evolution of dressings has evolved from the earliest passive dressings to interactive dressings, and then to today's bioactive dressings.
- The types of wound dressings are briefly explained as follows:
- 1. Passive dressing (traditional dressing), passively covers the wound surface and absorbs exudates, providing limited protection for the wound surface.
- 2. Interactive dressings. There are various forms of interactions between the dressing and the wound, such as absorbing exudate and toxic substances and allowing gas exchange to create an ideal environment for healing; the barrier outer layer structure prevents Invasion of microorganisms in the environment to prevent cross infection of wounds.
- 3. Bioactive dressings (closed dressings)
- This type of dressing is also called a closed dressing because it can prevent wounds from drying out. The dressing is a combination dressing made of high-molecular materials and biomaterials through high-tech processing, which is a hot spot in the research and development of wound dressings. The biosynthetic dressing has a double-layer structure, and the outer layer is applied with a polymer material, which provides a barrier function equivalent to the epidermis; the main materials selected for the inner layer are collagen, chitosan wound dressing [1] and calcium alginate, which have biological properties Compatibility, good water absorption, breathability, adhesion and antibacterial, hemostatic effect. It can not only absorb wound exudate and ensure full drainage, but also retain part of the exudate in the dressing to maintain a local moist environment that mimics the physiological healing of the wound, which is beneficial to the regeneration of wound granulation tissue and epithelial cells and accelerate wound healing. In synthetic dressings, some substances that are beneficial to wound healing, such as drugs, cytokines, and growth factors, can be added to form various dressings such as drug dressings, cytokine dressings, and growth factor dressings.
- Considerations when choosing a dressing
- 1. Assessment based on individual patient's condition
- The patient's physical, psychological, and economic acceptance of the dressing is also very important. Patients with different constitutions have different sensitivity to dressings, and some dressings may cause skin allergies in some patients. In some patients, dressings such as hydrocolloids and alginates are not acceptable. If patients have higher requirements for quality of life, the comfort and convenience of dressing become important reference factors for choosing dressings. New dressings are relatively expensive, but good dressings can reduce the number of replacements. The dressing should ultimately be used according to the patient's requirements.
- 2. Choose a dressing based on wound assessment. Gauze and film should be used for first-stage healing wounds; film should be used for superficial wounds; hydrogel for wounds with little to moderate exudation; alginates should be used for wounds with moderate to severe exudation; dry necrosis For wounds, hydrogel and hydrocolloid should be used.
- 3.Dynamic evaluation during use. Since the condition of the wound is constantly changing, the evaluation of the wound must be carried out at regular intervals. Based on the progress of the wound healing or the extent of the deterioration, evaluate at any time whether the most suitable dressing is selected and whether the dressing is used correctly.
- Concluding remarks
- It is difficult to say which dressing will be the most suitable for a wound, and even if the effectiveness of a dressing for such a wound has been proven, it may not be suitable for all patients. Therefore, it is the most reasonable to choose dressings dynamically and in combination with each other to select the dressing that is the safest, most effective, simple to use, and high cost-effectiveness ratio. At present, there are more products to choose from, and new products are constantly being introduced. The wound situation should be accurately evaluated, and economical, simple, and practical wound coverings should be selected to promote wound healing. Of course, the standards for ideal dressings are relative. With the development and progress of society, humans will have higher and higher requirements for dressings.
