Both iodophor and alcohol have disinfectant and antiseptic effects and are mainly used as disinfectants in clinical practice. Both can not directly promote wound healing, but can only provide a good environment for wound healing by keeping the wound in a clean and sterile state as much as possible, and assist the wound to heal. Too low a concentration may affect the effect of sterilization, while too high a concentration may cause significant irritation to the skin. Although smaller wounds can be disinfected with iodophor and alcohol, iodophor is relatively mild. Therefore, if the wound area is large, choose to use iodophor for wound disinfection, which is less painful. However, when some patients have wound trauma contaminated by grease type, the use of alcohol can penetrate the grease for wound disinfection, and alcohol can be chosen for disinfection at this time. 2. Disinfection range: iodophor as a disinfection preparation has a greater disinfection range, and in addition to killing bacteria, it also has a certain effect on some of the budding spores and viruses that alcohol cannot kill. In the process of wound healing, attention should be paid to dressing the wound under hygienic conditions, and you can use swelling and pain-relieving Chinese medicines to promote wound healing. If the wound appears pus, the wound should be drained and cleared in a timely manner, and the use of iodophor or alcohol may not achieve better results at this time. Daily attention should be paid to avoid contact with water, sweat, etc. to avoid contamination of the wound. When the wound is not completely healed, it should also be avoided to have a large amplitude of action resulting in wound tearing.
