Potassium permanganate can treat bacterial glans, using potassium permanganate solution to wash the glans locally can inhibit local bacterial reproduction and play a role in controlling inflammation. When using potassium permanganate solution to clean the glans, it can be combined with other antimicrobial agents to carry out treatment, but it is best to have a culture of local secretions before using antimicrobial agents, so that it can be clear what kind of bacterial infection is present, and target the selection of antimicrobial agents. Potassium permanganate provides an acidic environment, so that bacterial reproduction is inhibited, and plays a role in suppressing local inflammation. However, it is relatively ineffective for fungal glans, and also relatively ineffective for trichomonas glans, so it is recommended that patients should have a culture examination of local secretions to identify the specific infectious pathogens before using potassium permanganate. In addition, potassium permanganate needs to be diluted with water, if the concentration of dilution is too high, it may also lead to local chemical damage, resulting in local inflammation aggravation or local pain, bleeding, and the risk of local superficial ulcers.
