As a dermatologist, daily contact with many outpatients, day after day, the patient can reach thousands, slowly observe some findings: small area (not more than a palm area of their own) skin injuries such as: hot water burns, abrasions, motorcycle exhaust burns, etc., because the wound is not large, patients like to choose their own treatment, but the treatment is often incorrect. Generally there are the following situations: 1. a variety of topical drugs together, or keep changing the type of topical drugs, the result is not only ineffective, but also aggravate the infection, and even more so because the topical drugs themselves irritation led to allergies. So patients will say not only not well, but red and itchy as hell. Que Dongmei, Department of Dermatology, Zhongshan City Chen Xinghai Hospital 2. prefer to choose powder: patients come over and look at the surface to see that there is no running water (exudate), but it is still painful all the time and the base is red. 3. it is true that the wound is well, but the pigmentation is very obvious and unsightly, and does not subside for a long time. I would like to tell you some correct treatment: 1. scald (hot water, tail gas, etc.), immediately cold water rinse, lasting about 10 minutes, no hurry topical drugs, observe only redness, no blisters, no breakage, may not need topical drugs, or a topical burns cream or powder. 2. burns, blisters, and even epidermal breakage, the need for topical anti-infective drugs to prevent infection, such as Bactrim, fusidic acid, erythromycin cream and other topical drugs. The use of powder is not recommended for those with blisters or exudate. Another do not use a variety of topical drugs, a variety of topical drugs does not play a superposition of about. But there is a risk of allergy and so on. 3. local topical medication, should avoid irritating large drugs, if the use of stinging obvious, it is recommended to stop using and see a doctor. Also may aggravate the late skin pigmentation spots. 4. For pigmentation spots that have already formed, basically we can only wait for their metabolism to slowly fade away, and topical medication is not recommended. As long as there is no scar formation, hyperpigmentation can eventually fade away completely, but it will take a longer time. The above suggestions are only applicable to small area of skin damage, another if the damage is deeper, or local skin blackening, burning sensation, is sure to have to go to the hospital to avoid delaying the disease.
