Objective: To observe the clinical effect of nitrate-alum lotion in the treatment of wound edema after hemorrhoid surgery. Methods: Forty patients with wound edema after hemorrhoid surgery were randomly divided into two groups. There were 20 cases in the treatment group and 20 cases in the control group. The treatment group was treated with nitrate alum lotion, which was compared with the control group who used 0.02% potassium permanganate solution in warm water. Results: There were significant differences between the treatment group and the control group in terms of symptoms and signs improvement time and cure rate (p>0.05). Conclusion: Nitrate alum lotion has a definite effect in treating wound edema after hemorrhoid surgery, and it is worthy of clinical promotion.
