Anus fistula and perianal abscess are the most common and common perianal diseases in the anus, and due to the particularity of the physiological structure of the anus, the local anus wound is open after perianal surgery. Susceptible to faecal contamination and infection, healing is slow.
The local blood circulation of perianal is abundant, the wound is prone to hemorrhage, the exudate is many, affects the wound healing, so it is very important to choose the appropriate alginate dressing for local medicine change. Traditional methods include sitting bath, gauze, gauze stuffing and other methods, play the role of local compression hemostasis. However, this method has a long course of disease, and gauze and other dressings have limited absorption and seepage capacity, put in the wound quickly dry, again when changing the drug will aggravate the patient's pain and re-injury. and gauze dressing stuffing wound patients will appear a strong sense of feeling and a sense of rise, resulting in patients discomfort. Alginate Dressing-wool is a kind of wet dressing, which is used in pressure sores, sinus stuffing and anus fistula after operation. Because perianal subcutaneous nerve and blood vessels are relatively rich, so postoperative pain is more sensitive, alginate dressing can make the wound in a moist environment, reduce the stimulation of nerve endings, thus reducing local pain.
Wet environment is conducive to the formation of wound epithelial cells, so that the wound does not go through the general scab process and natural healing, and the healing speed is 1 time times faster than the dry environment. Avoid the exposure of the nerve endings of the wound, dehydration and the stimulation of certain inflammatory substances, so as to achieve pain relief effect, so the replacement of alginate dressing-wool when the patient has no pain and no sticky wound.
Wet environments can also maintain cell survival, allowing them to release growth factors and regulate and stimulate cell proliferation. Alginate dressing-wool separates sodium alginate from pure natural brown algae, and calcium alginate fibers are made by wet textile. It is rich in mannose acetaldehyde and calcium ions, through the complete replacement of calcium-sodium ions, the formation of moist gel. This semi-solid substance, similar to gel, isolates the wound from the outside world and forms a closed, atmospheric oxygen environment. Alginate Dressing-The gel formed by the wool can prevent wound dehydration, wound surface gel layer formation, the wound has a continuous debridement effect, placed in the wound after the wound bacteria, microorganisms and necrotic tissue are rapidly adsorbed, locked in the glue. Reduces defecation stimulation, acts as a quarantine of faeces, and avoids the chance of two infections.
At the same time, alginate dressing-wool makes the wound maintain a certain humidity and temperature, for the wound healing to create a good microenvironment, to promote early wound healing. Alginate dressing-The strip covered the wound after contact with the wound seepage, through ion exchange to the insoluble calcium alginate into soluble sodium alginate, due to the release of calcium ions, as a coagulation factor to participate in hemostasis, speed up the hemostasis speed. Therefore, alginate dressing is used to have good hemostatic drainage after operation.
Secondly, its absorption performance is good, can absorb its own weight of 17-20 times the amount of seepage.
Alginate Dressing in Anus fistula To sum up, alginate dressing-wool in the anus stuffing can achieve good hemostatic function and drainage while accelerating wound healing time.
With short course of treatment, good curative effect, fast healing and so on, alginate dressing is used in postoperative treatment of perianal abscess with high comfort and easy to be accepted by patients.
