Perianal abscess needs incision and drainage. If there is more body hair around the wound, it may affect the future surgical operation and wound care, so shave it off. Whether the operation or not, it is very important to do a good job of anal nursing. The specific points are: rinse the anus with water after defecation, smoke and bathe every day according to the doctor's advice, and sit in the air to let the anus breathe. The general doctor will give you an electric anal care set, which has an anal cleaner to help clean after defecation, an anal support pad to help suspend the anus, and an anal medicine basin to be fumigated and bathed on the toilet. But if the hospital is too expensive, you can also buy it online, but be careful not to buy fakes because of greed. For example, in order to observe the concentration of medical anal medicine bathtub, the basin body must be transparent, but it will be colorful because of ignorance, which will lead patients to misjudge the concentration of medical anal medicine. The sitz bath medicine should be diluted by 1: 50 potassium permanganate solution 100 times before use. Don't buy the wrong one with a concentration of 1:5000. It's for gynecology. At least ten bottles should be used for sitting bath in anorectal department. Patients with hematochezia should be washed with anal cleaner after defecation, and the wound should be thoroughly disinfected with anal disinfection towel, otherwise the residual bacteria will pollute the wound.
