It will be a bit troublesome. You should seek medical treatment promptly, and also pay attention to anus care, which means keeping the anus open for ventilation when sitting, cleaning it with water after defecation, and ensuring sufficient time for fumigation and sitz bathing. Prepare an electric anal care package, which contains an anal cleaner to help clean after defecation. Patients with blood in the stool should pay special attention. Not only should they use an anal cleaner to rinse after defecation, but they also need to wipe and disinfect with anal disinfectant wipes, because wounds with blood in the stool It will be contaminated by bacteria in the stool. If it is not disinfected in time, bacterial growth will cause the condition to worsen. Use warm water or potassium permanganate for fumigation and sitz bath in the anal medicated bath every day. The anal support pad can help to float the wound and promote the subsidence of edema. For sitz bath medicine, you need to buy 1:50 concentrated potassium permanganate solution. One bottle of diluted solution is enough for 10 sitz baths. Many patients mistakenly buy 1:5000 concentration, and 10 bottles are enough for one sitz bath. Anal care kits are available in hospitals and online. Pay attention to identification when buying online. For example, the airway tubes purchased by some patients are made of recycled opaque rubber and have a pungent smell. The airway tubes used in hospitals are transparent, colorless and odorless.
