Cold water shower is the first choice for scald
01. Emergency cooling is the key to branchial scald. The essence of branchial scald is that high temperature causes damage to tissues. It is the heat damage to the capillary wall in the dermis of the scalded part of the human body, which leads to increased permeability. The plasma seeps out of the blood vessels, resulting in local skin erythema and edema. If the capillary wall is severely damaged and the exudate is excessive, the exudate will accumulate between the epidermis and dermis and form blisters. When a scald occurs, only by removing the heat source immediately and reducing the local skin temperature of the scald, can we minimize the persistent damage of high temperature to human skin. So, rapid cooling is the first priority of first aid for scalds. Then, we can understand how to apply toothpaste. This is because toothpaste cold has cooling effect, and many toothpaste contains mint, mint cool, smear can make patients feel more pain relief, so feel toothpaste effective.
02 Toothpaste has potential safety hazards though cooling down. Through understanding the principle of scald, we know that the preferred treatment of scald is cooling. Although toothpaste has some cooling effect, from the whole situation, its cooling effect is not obvious, and there are many potential safety hazards. People know toothpaste is used for brushing teeth, not medicine. If the skin of the burned area is damaged, its barrier ability will decrease, making the injured area more susceptible to bacterial infection. Once the wound infection will affect the process of wound healing, so prevention and treatment of wound infection is also an important step in the treatment of scald. And toothpaste itself is not sterile, long-term use of toothpaste will inevitably exist bacteria, viruses and other microorganisms, such toothpaste applied to vulnerable wounds, will undoubtedly increase the chance of wound infection. In addition, there are many kinds of toothpaste, some are acidic, some are alkaline, and some contain very strong irritation. Applying toothpaste indiscriminately to the wound may also erode the wound and increase the damage of the wound. Thirdly, if the scald is serious and needs medical treatment, the toothpaste covering the wound will cover up the wound, so that the doctor can not immediately determine the size and depth of the wound, it must be cleaned before rescue. This process is time-consuming and laborious, but will increase the pain of patients. Therefore, in the face of many potential safety hazards after the application of toothpaste, the widow suggests that people should stop using partial prescription products such as toothpaste in case of scald.
03. Cold water is the first choice for scalding. As mentioned above, the temperature of scalded area should be lowered immediately after scalding. The simplest way is to find cold water and ice nearby to reduce local skin temperature. Cooling can stop heat from penetrating deep, and it can also shrink capillaries and reduce the occurrence of blisters. Cold water shower is a recommended method, which not only reduces the local skin temperature, but also plays a certain role in cleaning. If the area of small wounds can be immersed in cold water or ice water to cool down. Warm tips, do not use strong water flushing when flushing cold water, in order to avoid skin ulceration, increase the difficulty of recovery. As long as the cold water passes through the scalded surface, it can play a cooling role. If there is clothing covering in the scald area, we should go out of the hot and humid cover. The clothes that are not removed can be slowly removed by scissors. Do not tear the clothes when the clothes adhere to each other, so as to avoid unnecessary damage to the patients. After first aid, patients can assess excessive scald by themselves and take appropriate measures. Gill 1. The skin surface is reddish and swollen, with burning sensation and no blister. It is a first degree scald without special treatment. It will heal naturally in 3 to 7 days. Gill 2, if the local redness and swelling of scald is obvious, and there is blister formation, it is second degree scald. If the blister area is small, it can be absorbed and disappeared by itself. Avoid breaking blisters as far as possible to prevent infection. In order to prevent bacterial infection of wounds, antibiotics can be used for external use under the guidance of doctors. Gill 3. If blister area is large, or blister burst, or there are serious conditions such as wound skin sensation decline, timely medical treatment should be conducted to avoid adverse consequences due to improper self-management.
