How does burn scald blister do? How to deal with daily burns

In our life, we often encounter skin burns, especially in summer. For housewives, scalding is very common in the process of cooking, so how to deal with it in an emergency?

Blisters are a sign of second degree burns

When the patient is scalded or blistered in the injured area quickly after burns, the general burn doctor will locate such manifestations as second degree burns or light second degree burns. Although some patients are scalded or have blisters after burns, they do not show a very painful feeling of their own. The doctor also requires that you do not use a needle to prick the blister, let alone prick the blister and drain the water inside, because it is easy to cause bacterial infection. The second degree scald can be divided into two types: light second degree scald and deep second degree scald

1. Light second degree scald:

The superficial second degree scald is dermal injury. The clinical manifestations are obvious redness and swelling in the affected area, with blisters of different sizes, containing yellow plasma like liquid or peptone coagulated by protein. When the blister ruptures, we can see the wound with flush, soft texture, high temperature, and the patient feels intense pain.

2. Deep second degree scald:

Deep second degree scald is a deep injury of dermis with residual skin accessories. The clinical manifestation is that the vesicles are smaller or thinner, the sensation is slightly dull, and the skin temperature is also slightly lower.

Should scald blister be pricked?

Why don't you pick and break the blisters after burns under the guidance of doctors, which is easy to cause bacterial infection? Xiao Changming, director of burn and plastic surgery department of Neijiang No.1 People's Hospital, explained that small blisters appear on the local skin after burns, which generally belong to shallow second degree burns. The main substances in these vesicles are electrolytes, glucose, fibrin, etc. when these nutrients are combined, a good culture medium is formed for bacteria. Therefore, improper treatment of blisters can easily lead to wound infection.

Whether the blister of scald should be broken should be judged according to the situation. Generally speaking, small blisters do not need to be punctured, and keep the local dry. Blister skin is a good protective film, which can prevent infection, and it is best to let it absorb and heal by itself.

Standard treatment method for large blisters:

After local disinfection, use a sterile syringe to pump the blister solution or a needle to puncture the epidermis at the lowest position of the blister to release the solution, and use a sterile cotton swab to gently squeeze it to make the blister solution flow out fully at the lower position, while retaining the blister epidermis, then use a sterile dressing to wrap it, keep the local area clean and dry, and it will heal quickly. Do the above steps, and the blister will scab, dry and self heal quickly 。 If blisters are contaminated and cause infection, seek medical attention in a timely manner.

How to deal with burns scientifically?

If the fire and scald happen unfortunately, what should we do? It is very important to deal with it scientifically and reasonably at the first time. First of all, don't panic or deal with it blindly, which will not help the patient, but will bring more harm and pain to the patient. The specific operation methods are as follows:

1. Cold water washing:

In case of burn and scald, the patient shall be quickly separated from the fire source or heat source, and the affected area shall be immediately washed with tap water for 15 to 20 minutes, so as to achieve the effects of cooling, reducing residual heat damage, reducing swelling pain, preventing blistering, etc., and avoid deep skin damage due to excessive temperature.

2. Timely antiphlogistic:

Dip a cotton swab in light salt water and gently smear the burn area, which can play an anti-inflammatory role.

3. Don't handle it blindly:

Do not take off the clothes on the patient immediately, because the skin and clothes are adhered at the moment of burn and scald. Taking off the clothes will cause the wound surface to fall off and the injured part to be damaged again. If there is small blister on the wound, do not break it by yourself to avoid infection of the wound.

4. Do not use the wrong way:

Many people will apply vinegar, toothpaste and other 'earth' on the wound after burn and scald. There is no scientific basis for these 'earth'. Not only the purpose of treating burn and scald can not be achieved, but also the wound will be blurred after being coated with solid or liquid with color, which will cause great inconvenience to the wound cleaning and increase the pain of patients.

After cold water cooling and other treatment, the patient was immediately sent to the hospital for treatment. In the process of transportation, pay attention to avoid wound infection, use clean sheets, clothes and other simple bandages, and avoid pressure. At the same time, pay attention to prevent bumps and maintain the speed.
