In the process of wound treatment, there are many different types of dressings. According to the feedback from clinical researchers, there is such a dressing in the clinic. It can not only be used alone, but also often used in conjunction with other dressings to create an excellent environment for wound protection. It can be said that it is one of the most commonly used dressings in the dressing industry, and it is a hydrocolloid dressing. So what makes it so attractive?
Hydrocolloid dressings are made from a hypoallergenic water-like adhesive and polyurethane or polyurethane foam that contacts the wound. On contact with the wound surface, the hydrocolloid dressing creates a moist healing environment that reduces pain, forms a moist gel, inhibits bacterial infection and promotes wound healing. It is especially suitable for chronic wounds that cannot be healed for a long time, as well as complex and time-consuming tissue regeneration treatment and prevention. It is also suitable for venous ulcers, second-degree burns, skin graft donor sites, and pressure ulcers.
The role of hydrocolloid dressings in the prevention and treatment of scars: The role of silicone dressings in the prevention and treatment of scars has been proven, but what about the role of hydrocolloids? A prospective study found that in the process of treating scars with hydrocolloid dressings, the itching and pain of the patients were significantly relieved after two months, the flexibility of the scars was also increased, and the pigmentation was also reduced, indicating that the hydrocolloid dressings can relieve the scars. symptom.
The fluid absorption capacity of hydrocolloid dressings varies widely among products from different manufacturers and is closely related to the length of time they are used. Hydrocolloid dressings are not suitable for moderately to highly exuding wounds. The hydrocolloid dressing is essentially a moisturizing dressing, which maintains a moist environment after absorbing and locking the exudate. It has a certain exudate absorption capacity, but it is not strong, and is only suitable for low to moderate exudate wounds.
Pain is one of the hallmarks of superficial wounds, especially when dressings are changed. Results of a prospective study showed that hydrocolloid dressings provided better pain relief in patients and, in addition, resulted in faster wound healing at the donor site. The exact mechanism by which hydrocolloid dressings relieve pain is not well understood, but some studies have also given some explanations, such as nerve endings feel less pain in a moist environment, and the sealing properties of hydrocolloid dressings allow them to better protect wounds.
