Wound dressings are the core tool of wound care. Wound dressings influence the quality of wound care，such as the healing speed of wound and the quality of wound healing. So, the selection of wound dressings is important. The scientific selection of dressings depends on characteristics of different wounds, the stages of wound healing, and the properties of various dressing materials. I will help you choose appropriate wound dressing base on different wound types and healing stages, so that improving clinical outcomes, wound management efficiency, and patient satisfaction.
Wound types are diverse, including open wounds, surgical wounds, chronic wounds, burns or scalds, and infected wounds.
An open wound refers to a break in the integrity of the skin or mucous membrane, exposing underlying tissues such as muscles, fat, or bones to the external environment. It include abrasions and lacerations. Such wounds are usually accompanied by bleeding and bacterial infection easily, requiring timely cleaning, hemostasis, and dressing with wound dressings. If open wound not be cared correctly, it may lead to serious complications such as tetanus and sepsis.
Surgical wound refers to an intentional injury to the skin and tissues caused by surgical procedures (such as incisions, suturing, or minimally invasive techniques). The healing process of surgical wound is more complex than ordinary wounds, the wound often presenting symptoms like redness, swelling, discharge, or sutured/closed marks, requiring strict and professional care.
Chronic wounds refer to that fail to heal through the normal healing process within 4-12 weeks and are easy to recurrence, such as diabetic ulcers and pressure sores. The healing of chronic wounds requires professional dressing interventions.
Burn wounds commonly exhibit varying degrees of swelling and blisters. In addition to topical dressings, surgical intervention can also be used to accelerate the healing of burn wounds.
An infectious wound refers to a pathological wound caused by the invasion of bacteria, fungi, viruses, or other pathogens into the injured area, leading to local or systemic inflammatory responses. It typically requires surgical debridement, antibiotic therapy, and specialized dressing for auxiliary treatment.
There are three key stages during wound healing: the inflammatory phase, the proliferative phase, and the remodeling phase. The inflammatory phase involves redness, swelling, and pain, lasting 0-3 days.
The proliferative phase is characterized by red, granular tissue with epithelial cells covering the wound surface, typically lasting 3-21 days. During the remodeling phase, the scar gradually softens and flattens, lasting from 21 days to 1 year. Due to the wound healing status varies at each stage, the focus of wound care also different.
Wound dressings are designed to promote healing or prevent further tissue damage. High-quality dressings can achieve multiple objectives, including including providing an appropriate level of moisture and serving as a barrier to bacterial invasion. The idea dressings has high permeability, provides thermal insulation, supplements enzymes and growth factors. I will introduce types of dressings and advantages or disadvantages of dressings, help you select wound dressings efficiently.
Gauze has excellent breathability, with its cotton fiber structure allowing free air circulation and reducing the risk of overheating. At the same time, gauze is more cost-effective compared to advanced dressings. However, gauze cannot maintain a moist environment and requires frequent changes so that increasing the nursing workload.
Dermlin is a composite dressing, the core feature of Dermlin contain inorganic elements such as calcium and silicon, which accelerate healing by stimulating cell proliferation and exerting antibacterial effects, reducing care costs effectively. Dermlin dressings have a wide range of applications and can be used for both acute and chronic wounds.
The film dressing is easy to apply so that saving bandaging time. It also provides a moist healing environment, accelerating wound recovery. The polyurethane/silicone layer blocks external moisture and bacteria, reducing the risk of infection. Its transparent design allows real-time monitoring of the healing progress. However, its limited exudate capacity makes it unsuitable for infected wounds.
Foam dressings are a commonly used dressing for moderate to highly exudative wounds, made from polyurethane or silicone foam materials. They can absorb a large amount of exudate, reducing nursing burden and healthcare costs. Compared to traditional gauze, they can improve wound healing rates by 20%. However, due to their strong absorbency, they are not suitable for dry wounds, and their thickness may restrict joint movement.
Hydrocolloid dressing is a self-adhesive, semi-occlusive wound dressing which include hydrophilic colloidal particles as core ingredient. It features high moisture retention, waterproofing, antibacterial properties, and high comfort, effectively promoting wound healing, reducing pain, and thereby lowering care costs.
Alginate dressing is a highly absorbent, biodegradable biological material primarily composed of calcium/sodium alginate, which is natural and non-irritating. It provides a moist wound-healing environment and promotes rapid hemostasis. However, due to its low adhesiveness, it must be secured with gauze or film dressings and requires frequent changes, increasing wound care difficulty.
Silicone Dressing is a hypoallergenic, non-adherent wound dressing. It made of medical-grade silicone which has gentle adhesion, scar reduction, and easy replacement. However, it has low stickiness and easy to fall off, the price of silicone dressing is relatively more expensive than film dressings.
Film Dressing is suitable for open wounds such as skin tears and abrasions, because these materials are semi-permeable and have good therapeutic effects on the healing of superficial burns, minor abrasions, and lacerations. Meanwhile, foam dressings are highly absorbent and also suitable for the care of open wounds. It can absorb a large amount of exudate, compared to film dressings, foam dressings are more effective in promoting the healing of skin tears.
Hydrocolloid dressing and Dermlin dressing are suitable for postoperative wounds and chronic wounds. When there is exudate from a wound, hydrocolloid dressings absorb the fluid and form a gel, thereby maintaining a moist environment. They are an ideal choice for postoperative wounds and ulcer wounds.
Foam dressings and alginate dressings are suitable for infected wound, because both foam dressings and alginate dressings can absorb large amounts of exudate and provide a moist environment to promote healing.
There are different care needs at each stage of wound healing. To effectively manage the wound at each stage, selecting the appropriate wound dressing is crucial. No single wound dressing is suitable for all stages of healing.
During the inflammatory phase of a wound, the core needs of wound care are controlling exudate and inhibiting bacteria. Therefore, the dressings used in the inflammatory phase must have strong absorbency and antibacterial properties. Alginate dressings and Dermlin Dressing are the best choices for this stage.
The core needs of wound care are to promote granulation tissue growth and regulate epidermal regeneration, while balancing exudate management during the proliferative phase. Therefore, dressings that provide a moist wound environment, such as Dermlin Dressing, foam dressings, and hydrocolloid dressings, should be selected.
The core requirements are collagen remodeling and scar management during the remodeling phase . Therefore, the care dressing needs to have moisturizing and anti-scar effects. Silicone dressings are the best care dressing for this stage.
The requirements for wound care dressings are different among different groups. For special groups such as children, the elderly, and pregnant women, the safety and comfort requirements of dressings are more stringent.
The selection of wound dressings for children focuses on safety and comfort. Prioritize non-irritating, hypoallergenic materials such as hydrocolloids, silicone dressings, or Dermlin Dressing. Avoid products containing alcohol or strong adhesives. Opt for lightweight, soft dressings like foam dressings to minimize skin friction.
The skin of elderly individuals is fragile, so opt for dressings with silicone edges or painless removal, such as silicone patches. For elderly patients with diabetes, Dermlin Dressing is a more suitable choice.
Pregnant women should choose hypoallergenic, breathable, and medication-free dressings. Dermlin Dressing, silicone, hydrocolloid, or foam dressings are the first choice.
Selecting wound dressings requires an understanding of the wound healing process. The choice of dressing depends on a holistic assessment of the patient, the characteristics of the wound, and the stage of healing. Cost, availability, and shelf life are also important considerations when ordering dressings.
