Wound dressing is an important part of surgical nursing work. How to eliminate all the factors that are not conducive to healing in the wound as much as possible, strengthen and create all conditions conducive to wound healing, is an urgent problem to be solved, and also the direction of exploration. Conventional dressings have the effect of absorbing wound exudate and isolating the wound. The requirements for dressing materials are only considered to be biologically inert, non-toxic and biocompatible. Therefore, the dressing of this conventional structure causes a more dry environment of the wound, dehydrating and crusting the wound, and causing secondary damage during the healing process. Since Witter (1962) proposed the theory of "wet healing", it was found that epithelial cells migrate faster than exposed wounds in a humid environment and without scarring. It is believed that promoting more binding of growth factor receptors to growth factors in a humid environment may be the basis for wound healing in moist environments. A large amount of basic research and clinical practice has also been proven.
In the past ten years, due to the development of science and technology, especially the advancement of materials science and processing technology, various types of modern medical biological dressings have emerged. Changed the principle of wound healing and deepened the understanding of clinical care for the dressing process. Alginate dressing is one of the new wet dressings. It is a medical alginate fiber produced by Foshan Youte Medical Technology Co., Ltd., which is imported from seaweed by the introduction of British technology and independently developed alginate dressing. . Alginate is combined with certain hydrophilic synthetic polymers to form alkaloids with Ca2+ to obtain a dressing with high water content, high elasticity and toughness.
