Effect of Different Sitz Bath Methods on Perianal Abscess After Surgery

Perianal abscess is a purulent infection of the tissues surrounding the anal canal and rectum. The postoperative wound is prone to infection, and the literature indicates that hip bathing is helpful to prevent infection, reduce edema, and promote healing. Therefore, patients need to use a bidet for medical sitz bath to avoid infection and contamination. The bidet on the market is divided into ordinary type and rinse type (manual or electric). There are no high-quality studies comparing the effects of these sitz baths. A prospective randomized controlled trial was designed to investigate the effects of regular sitz bath, manual irrigation, and electric irrigation. A total of 102 patients with perianal abscess in the Affiliated Hospital of Putian University were included in the study. The patients were 18-75 years old and underwent surgical treatment. Patients with recurrent abscess, anal fistula, mental disease, pregnant or lactating women, and diabetes were excluded. The patients were divided into general group, manual group and electric group by random number table method, with 34 cases in each group. All patients received hip bathing with 0.02% potassium permanganate solution at 41-43 ° C three times a day for 10-15 minutes each time after surgery.
