For women who need to use potassium permanganate for sitz bath, the concentration is usually 1:5000, that is, one part of potassium permanganate solution to 5000 parts of water, the color of the solution is light pink, the concentration of potassium permanganate solution will not stimulate the vulvar skin, causing discomfort such as burning and stinging of the vulva, and will not have other abnormal effects on the vulva. At present, it is commonly used for two kinds of women: first, women who have poor absorption of sutures after normal delivery can promote the natural discharge of sutures by taking a sitz bath with potassium permanganate solution, which has the effect of disinfection and sterilization. Second, women who undergo vestibular gland submerged stoma surgery need to take a sitz bath with potassium permanganate solution to prevent infection of all the incisions. If women just use potassium permanganate to disinfect gloves or ordinary blades, they can use a concentration of 1:500, but they should not directly dip their hands in the solution to avoid damaging the skin.
