In the winter and spring, many patients with burns caused by hot water bags and electric heating cakes come to the clinic one after another, and some of them have been transferred to several hospitals and told that they need skin implants, so they come to try Chinese medicine treatment with the idea of trying. This kind of burns we call low-heat burns, the so-called low-heat burns, refers to the human skin for a longer period of time exposure to relatively low temperature (44 ~ 51 ℃) of the heat source caused by the injury. Life happens from time to time, mostly caused by careless heating, but also part of the medical source of injury, such as moxibustion, fire pot accident, physical therapy lead plate burns, etc.. The clinical manifestations have the following characteristics: Initially, there are more blisters, and smaller, the appearance of color is often darker, which is the blister fluid with more blood or traumatic stasis caused by blood. After the blisters are cleared, necrotic foci can be found on the trauma surface in addition to petechial hemorrhage. Some trauma surfaces can also appear pale. Low sensation or loss of sensation on the trabecular surface. Because of the presence of blisters on the trauma when the patient is first seen, it is often misdiagnosed as a deep second-degree or even shallow second-degree burn. Compared with high-temperature burns, low-heat burns have a small temperature difference and slow dehydration of superficial tissues, but due to the long duration of action, large heat capacity, and more heat conduction to deep tissues, coupled with the cumulative effect of thermal injury, the tissues form “baked white potato”-like changes, and the skin is not scorched by the fire but the lining (flesh) is cooked. We have achieved satisfactory results in the clinical treatment of this disease by combining the internal and external methods of Chinese medicine, so that patients can avoid skin implantation, and no obvious scars, and the local pigmentation changes slowly approach the surrounding normal skin over time. In the internal treatment, we should pay attention to: 1. Do not overuse cold and heat-clearing products to prevent Yang Qi from being suppressed and aggravate blood stasis, as well as bitter-cold medicine that hurts the spleen and defeats the stomach; 2. For diabetic patients, we should closely monitor the fluctuation of blood sugar and take medication on time to avoid prolonging the treatment time. In the external treatment, we should pay attention to: 1. remove the blister skin on the wound in time to keep the drainage unobstructed and prevent the “closed door”; 2. cut into the necrotic tissue vertically when correcting it so that the stasis surface is thoroughly exposed; 3. expand the wound appropriately when the wound has a large bottom and small burned bowl-like shape; 4. when a submerged cavity exists, it is important to When there is a latent cavity, it is necessary to patiently put the antiseptic drug in full contact with the necrotic tissue in the cavity, and make sure that the evil is removed, so that the necrotic tissue does not remain and liquefy to become a source of pus and rot and further expand the scope of the cavity; 5, when the pus and rot in the cavity are exhausted and the muscle wants to grow, cotton balls can be placed on the surface projection of the cavity and pressed to make the tissue adhere and the cavity close; 6, when the muscle is flat and the skin is long, cotton pads and wrapping method should be used to prevent the granulation from growing high and affecting the epithelial crawl, delaying the healing of the wound.
