How to change the dressing after anal fistula operation?

Postoperative dressing change can be as follows: ① clean the wound surface and prevent pollution by cleaning and wiping the secretion and feces of the wound surface; (2) Adding oil sands strips during dressing change can not only discharge pus and secretions smoothly, but also protect the wound surface; ③ Some drugs used in dressing change can promote wound growth; ④ granulation with edema can be treated in time; ⑤ By filling oil sands, the wound can be separated, bridge healing can be avoided and recurrence can be prevented in the future. The specific methods of nursing dressing change after anal fistula surgery should also be different according to the condition. In the first few days after the operation, we should pay great attention to the cleaning of the wound. High or complicated anal fistula should be washed, and the washing solution should be normal saline and hydrogen peroxide if necessary. The contained oil sands should fill the whole wound, especially the inner mouth, and must be compacted. With the decrease of secretion, clean wounds can be wiped with normal saline, and the oily sand strips contained in them should also be gradually reduced. At this time, the focus of observation is to prevent granulation edema and bridge healing. Granular edema can be scraped off with a scraper. If the bridge healing has been formed, it should be cut off in time. Ointment should be used less in the early stage of secretion, and ointment can be used appropriately in the later stage to promote healing. In addition to general methods, anti-tuberculosis drugs should also be used on the wound surface for dressing change of tuberculous anal fistula. The frequency of dressing change depends on the amount of secretion. In principle, it is once a day after defecation, except in special circumstances. The more frequent the dressing change, the better. Sometimes too much dressing change will be counterproductive. There is a saying in Chinese medicine called simmering pus to grow meat, which means that a thin layer of secretion on the wound will promote the growth of meat. Re-emphasize that postoperative nursing and dressing change are very important, and the treatment of internal orifice of anal fistula is the key to treatment. If the internal orifice cannot be found during the operation, or the internal orifice is not handled properly, the fistula cannot be completely cured. Even if the operation of anal fistula is successful, postoperative nursing is very important to prevent the recurrence of anal fistula, and patients still have nervousness after operation.
