Yes, diet is on the one hand, but also pay attention to anal care, that is, keep the anus clean, breathe while sitting, and fumigate with warm water or traditional Chinese medicine. The specific method is to prepare an electric anal nursing bag, which is equipped with an anal support pad, which can ventilate the anus and promote wound healing. After defecation, the anus cleaner washes the anus with water, and the patient with hematochezia is anal rupture. After washing, you need to use an anal disinfectant towel to avoid repeated inflammation of the wound caused by bacteria remaining in the stool. It is best to fumigate the anal basin with potassium permanganate in sitz bath. When purchasing, please pay attention to the use of potassium permanganate solution with concentration of 1:50 in anorectal department, and dilute one bottle enough for sitting bath 10 times. Don't buy the concentration of 1:5000 by mistake. This is for andrology or gynecology. You can only use 10 bottle in a sitz bath. There are anal care packages in hospitals and online. Pay attention to identification when buying, and don't buy fakes. For example, the height of the anal support pad used in the hospital is 8 cm to ensure that the wound is suspended, while the fake one is generally 7 cm, and the overhead area is designed to be very small, so many patients with wounds on the side simply do not need it.
