Alginate wound dressings are a type of functional wound dressing composed of alginate, which has high absorption capabilities. When this medical film comes into contact with wound fluid, it forms a soft gel, providing an ideal moist environment for wound healing, promoting wound healing, and relieving pain. Alginate wound dressings can be used for the treatment of infected wounds, but they should be used under the guidance of medical staff and in conjunction with other treatment measures. Additionally, medical staff should regularly evaluate clinical indications and examine the wound condition of the patient.
The liquefaction of fat in surgical incisions directly affects the normal healing and postoperative recovery of patients, prolonging their hospital stay. Alginate wound dressings have good efficacy in caring for surgical incisions with liquefied fat. Alginate wound dressings have strong absorption capabilities and can dissolve and clear necrotic tissue, effectively controlling exudate. Alginate wound dressings not only absorb exudate within wounds but also absorb and trap deep bacteria and cellular debris in the gel, achieving rapid and effective debridement. The moist healing environment can accelerate granulation tissue formation and ultimately accelerate wound healing. Moreover, when changing Alginate wound dressings, they can be fully removed while protecting the base of the incision and without affecting fresh granulation tissue, promoting incision healing and significantly reducing pain during dressing changes.
Surgery is currently the main method for treating complex anal fistulas, and dressing changes for the incision after complex anal fistula surgery are crucial to ensuring treatment efficacy. Due to the special physiological structure of the anus, there is generally more bleeding and exudate after perianal surgery, and the perianal incision is open and prone to contamination by fecal matter, making it susceptible to infection and resulting in delayed healing. Alginate wound dressings form a fibrous gel-like substance when they come into contact with the wound exudate, absorbing liquid and swelling to form a soft, moist, gel-like, semi-solid substance on the wound surface, isolating the wound from the outside world and creating a closed, anaerobic environment that promotes angiogenesis and maintains moist wound-healing environment by increasing the regenerative capacity of epidermal cells, accelerating their movement, and promoting wound healing. Additionally, it releases calcium ions while undergoing sodium/calcium ion exchange with exudate, providing hemostatic effects.
