Sitz baths for perianal abscesses depend on whether it is before or after perianal abscess surgery. If a perianal abscess is not treated surgically, it is not recommended to treat it with a sitz bath. Sitz bath with warm water has the effect of improving blood circulation around the anus, which may cause perianal abscess lesions to expand, and perianal abscesses should be treated by surgery in hospital in time. If it is postoperative, you can use warm boiled water or potassium permanganate water, and you can also use light salt water to take a sitz bath, which can improve the blood circulation around the anus and accelerate the recovery of the incision. In addition to the sitz bath, regular specialist dressing changes should be performed, and gauze should be stuffed into the incision site for drainage, which can drain the secretions from the incision site and prevent pseudo-healing of the incision.
