Hydrocolloid dressings may help heal chronic wounds

1. The magical effect of hydrocolloid dressing in the prevention and treatment of phlebitis


Phlebitis is one of the most common complications of intravenous infusion administration. Studies have shown that the incidence of phlebitis can reach as high as 44% in patients with peripheral venous catheter intubation (the average catheterization time is about 11 days).


Even if relatively catheterized the incidence rate of emergency patients with shorter time is also as high as 31%. Intravenous infusion care is one of the important contents of clinical nursing work, and the high incidence of phlebitis not only brings pain to patients, but also increases the difficulty of work for clinical medical staff. Smart nursing experts have found that hydrocolloid dressings can effectively prevent and treat phlebitis in clinical work, and to a certain extent, hydrocolloid dressing patches are effective in preventing and treating chemotherapy-induced phlebitis and mechanical phlebitis.


Regardless of the prevention or treatment of phlebitis, the hydrocolloid dressing has a clear mechanism, and the semi-permeable membrane structure creates a hypoxic environment, promotes local capillary regeneration, accelerates local blood circulation, accelerates the resolution of inflammation, and effectively prevents or relieves symptoms related to phlebitis; and Compared with methods such as traditional Chinese medicine mixture or wet compress, it can significantly reduce the workload of nursing, is easy to use, has good application properties, does not affect activities, and is easier for patients to accept. The application of hydrocolloid dressings in phlebitis deserves to be widely promoted.


2. Hydrocolloid dressings can not only cover wounds, but also help wounds heal


Hydrocolloid dressings can absorb a large amount of exudate and toxic substances, maintain sufficient humidity in the wound, allow oxygen exchange, be impermeable to microorganisms, and be non-invasive when changing the dressing. Hydrocolloid dressings can be used for chronic wounds and leg ulcers. In the early stages of wound healing, inflammation increases capillary permeability, resulting in excess fluid flow into the wound. Exudate decreases over time during wound healing, but in non-healing wounds during the inflammatory phase, exudate levels are consistently higher. Too much or too little exudate can interfere with healing. The hydrocolloid dressing can be left for 24 hours to 5 days. The dressing interacts with the wound exudate to form a soft protective gel in the wound. There is a typical smell after opening the dressing. Hydrocolloid dressings limit exudate at the wound site and prevent the spread of exudate to the periwound skin; controlling exudate levels while maintaining a moist wound healing environment. The purpose of hydrocolloid dressing is to remove harmful bacteria and enzymes from the wound bed to prevent them from hindering wound healing; to reduce pain and discomfort for patients when applying and changing dressings.


Epithelial cells require water to migrate from the wound edge to re-epithelialize or close the wound. In dry wounds, these cells migrate to the moist area below the wound. But in a moist wound environment, cells can migrate directly in the wound, which speeds up the healing process. Hydrocolloid dressing patches provide wounds with a moist and airtight environment, which is conducive to the dissolution of necrotic tissue, maintains a low-oxygen state in the local microenvironment of the wound, promotes the release of various growth factors, and promotes the formation of capillaries; the moist and airtight heat preservation environment is conducive to Migration, proliferation and differentiation of cells, thereby promoting healing.
