 Burns and Scalds 

A burn is an injury caused by dry heat e.g. fire, hotmetal etc. while a scald is  an injury caused by  moist heat  e.g. steam and hot or corrosive liquids

Types of Burns and Scalds

Burns and scalds can vary in severity, classified as first-degree, second-degree, or third-degree burns:

• First-degree burns: These are superficial burns that affect the outermost layer of the skin (epidermis). They are characterized by redness, pain, and minor swelling. Sunburns are an example of first-degree burns.

• Second-degree burns: These burns affect both the outer layer (epidermis) and the underlying layer of the skin (dermis). They cause redness, blistering, pain, and swelling.

• Third-degree burns: These are the most severe burns, affecting all layers of the skin and potentially underlying tissues. Third-degree burns can appear white, brown, black, or charred. They may be less painful initially due to nerve damage.
  

Burns and scalds can be further  classified into different types based on the cause and severity of the injury. Here are the common types of burns and scalds:

1. Thermal Burns: Thermal burns occur due to contact with heat sources. They can be caused by flames, hot objects, steam, or hot liquids. The severity of thermal burns depends on the temperature, duration of exposure, and the area of the body affected.

2. Chemical Burns: Chemical burns result from contact with corrosive substances, such as acids, alkalis, or strong cleaning agents. These burns can cause damage to the skin and underlying tissues and may continue to harm the affected area until the chemical is neutralized or removed.

3. Electrical Burns: Electrical burns occur when an electric current passes through the body. They can be caused by electrical appliances, faulty wiring, or lightning strikes. Electrical burns can be deceiving as the external damage may not reflect the severity of internal injuries.

4. Radiation Burns: Radiation burns are caused by exposure to ionizing radiation, such as from X-rays, radioactive materials, or radiation therapy. These burns can be severe and have long-term effects on the skin and underlying tissues.

5. Friction Burns: Friction burns result from the skin rubbing against a rough surface. They commonly occur during falls or accidents involving high-speed activities like cycling or sports. Friction burns can range from mild abrasions to deeper tissue damage.

6. Cold Burns (Frostbite): Cold burns, also known as frostbite, occur when tissues freeze due to extreme cold temperatures. Frostbite typically affects the extremities, such as fingers, toes, ears, or nose, and can result in tissue damage or even tissue loss.

7. Scalds: Scalds are burns caused by hot liquids or steam. They commonly occur in the kitchen from boiling water, hot beverages, or cooking fluids. The severity of scalds depends on the temperature of the liquid and the duration of exposure.

First Aid for Burns and Scalds 

First aid for burns and scalds aims to provide immediate care to minimize pain, prevent further injury, and promote healing. Here are the steps to follow:

1. Ensure safety: Make sure the area is safe for both you and the injured person. If necessary, remove the person from the source of the burn or eliminate the burning hazard.

2. Stop the burning process: If the burn is caused by heat, extinguish flames or remove the person from the source of heat. For scalds, quickly remove any clothing or jewelry that is not stuck to the skin, as they can retain heat.

3. Cool the burn: For minor burns (superficial first-degree or small second-degree burns), cool the burned area with cool (not cold) running water for at least 10 minutes. This helps to reduce pain, prevent deeper injury, and minimize swelling. Avoid using ice or icy water, as they can cause further damage.

4. Remove constrictive items: Take off any constrictive items like rings, bracelets, or tight clothing near the burned area, as swelling may occur.

5. Cover the burn: After cooling the burn, cover it with a sterile, non-stick dressing or a clean cloth to protect it from dirt and reduce the risk of infection. Avoid using adhesive bandages directly on the burn.

6. Provide pain relief: Over-the-counter pain medications, following the recommended dosage, can be given to help alleviate pain. However, consult a healthcare professional or follow local guidelines before administering any medication.

7. Seek medical attention: It’s important to seek medical help for burns that are severe, cover a large area of the body, or are deep (third-degree burns). Also, burns caused by chemicals, electricity, or inhalation should be evaluated by a healthcare professional.

8. Don’t pop blisters: If blisters form, do not pop them. They serve as a protective barrier against infection. Allow them to heal naturally.

9. Elevate the burned area (if applicable): If the burned area is in an extremity, elevate it to reduce swelling, unless it causes more pain or discomfort.

10. Monitor for complications: Watch for signs of infection, such as increased redness, swelling, pain, or pus. Also, be vigilant for signs of shock (pale skin, rapid heartbeat, shallow breathing) and seek immediate medical attention if present.

Remember, proper medical assessment and treatment are crucial for more severe burns or burns that cover a large area of the body. These first aid steps are intended for immediate care, but professional medical help should be sought as soon as possible for appropriate evaluation and management.
