Wound hemostasis The traditional first aid hemostatic dressing is mainly the first aid kit, four headband and other cotton dressings (such as cotton, bandages, gauze, etc.), only rely on physical pressurization to stop bleeding, hemostasis effect is not poor, often with the help of tourniquet to control wound bleeding. The indications of alginate dressing in various surgical wounds are mainly embodied in three aspects: absorbing wound exudate, promoting hemostasis, and providing a moist healing environment for the wound. At the same time, alginate dressings can also relieve pain in the wound, and can absorb the protease of the wound, accelerate the healing process of the wound.
When alginate dressing is applied to cutting injury, pressure sores and bleeding wound in the feeding area, the calcium ions in the fiber are exchanged with the sodium ions in the wound exudate to form a gel, and when the calcium ions are released, the mass assembly of calcium ions on the wound surface can accelerate the hemostasis of the wound.
Surgical incision The fat liquefaction of the incision directly affected the normal healing of the incision and the postoperative rehabilitation of the patients, and prolonged the hospitalization time of the patients. Alginate Dressing has a good effect on the treatment of fat liquefaction of surgical incision. Alginate Dressing has strong absorbability, and the dressing has self-soluble debridement effect, which can accelerate the dissolution and removal of wound necrosis tissue and effectively control the seepage fluid. Alginate dressing can not only absorb the seepage in the wound, but also absorb and lock the deep bacteria and cell debris in the gel, to achieve the role of rapid and effective debridement, its moist healing environment can accelerate the formation of granulation tissue, and ultimately accelerate wound healing. In addition, the dressing can be completely removed, while protecting the base of the incision without affecting the fresh granulation tissue, which not only promotes the healing of the incision but also significantly reduces the pain during the change of medicine.
Nasal surgery Nasal tamponade is a traditional Chinese medicine measure to treat nasal hemorrhage and prevent bleeding, adhesion or restenosis after nasal sinus surgery. Alginate dressing in the blood or the mouth of the sodium salt into a gel shape, with good biocompatibility and hydrophilicity, can absorb a large number of exudate, while promoting necrotic tissue shedding, cleaning wounds, accelerated wound healing and epithelial repair, especially in nasal surgery can accelerate the adhesion of platelets and red blood cells, promote hemostasis, and the formation of colloids on the wound can reduce the pain of patients, so it is suitable for nasal surgery wound care.
The results of clinical use of alginate medical dressings showed that less bleeding during filling and extraction could reduce nasal pain and light nasal mucosal edema after operation.
Anus Fistula Surgery is the main method to treat complex anus fistula, and the wound replacement after operation of complex anus fistula is the key to ensure the therapeutic effect. Because of the special physiological structure of the anus, the phenomenon of bleeding and seepage of the wound after perianal surgery is generally more, the local wound of the anus is open, the stool is polluted, the infection is easy to occur, and the healing is slow. The alginate dressing forms a fibrous colloid after contact with the wound exudate, absorbs the liquid and expands, forms a soft, moist, gel-like semi-solid substance on the wound, isolates the wound from the outside world, forms a closed non-atmospheric oxygen environment, accelerates the neonatal microvascular hyperplasia, can maintain the wound moist environment, Improve the regeneration ability of epidermal cells, speed up the movement of epidermal cells, and promote wound healing. In addition, with the seepage of sodium ion/calcium ion exchange at the same time release calcium ions, with accelerated hemostasis function.
