Understanding Thermal Burns: Causes, Symptoms, and Prevention

What are Thermal Burns?

Burns are among the most frequent household injuries, often occurring during daily activities like cooking or handling hot items. In the United States, nearly half a million individuals visit emergency rooms each year due to various types of burn injuries.

Burns can result from:

  • Heat
  • Electricity
  • Radiation
  • Chemicals
  • Friction
  • Cold

A thermal burn specifically occurs when the skin comes into contact with high-temperature objects or substances, such as boiling water, hot surfaces, or steam. Infants and young children are particularly susceptible to thermal burns, with approximately 25% of burn injuries affecting those under the age of 15.

This article explores critical questions regarding thermal burns, including their causes, symptoms, treatment options, and prevention methods.

Causes of Thermal Burns

Thermal burns account for a significant portion of burn incidents in the U.S., originating from both dry and wet heat sources. Wet heat burns are often referred to as scalds.

Sources of Heat:

Dry heat can stem from:

  • Open flames
  • Hot metals, glass, or similar materials

Wet heat can be caused by:

  • Hot water, oils, or other liquids
  • Steam

Moreover, inhaling smoke, steam, or heated air can cause serious airway burns.

Identifying Symptoms of Thermal Burns

The symptoms associated with thermal burns vary depending on their severity and location. Typically, symptoms worsen in the first few hours or days after the injury.

Common Symptoms Include:

  • Pain
  • Blisters
  • Swelling
  • Redness, whiteness, or charred appearance of skin
  • Peeling skin

Signs of Airway Burns:

  • Burns on the head, face, neck, or upper respiratory tract
  • Burns on lips or inside the mouth
  • Coughing or difficulty breathing
  • Black-stained mucus or changes in voice
When to Seek Emergency Help:

If experiencing the following symptoms after a thermal burn, seek immediate medical care:

  • Signs of airway injury
  • Burns on the face
  • Burns in children or the elderly
  • Minimal pain in the burn area
  • Burns larger than three inches
  • Pus or discharge from the burn site
  • Worsening pain over time
  • Changing characteristics of the burn
  • Unpleasant odor from the burn
  • Fever
  • Shock symptoms, such as pale skin, confusion, and weakness

Classification of Thermal Burns

Medical professionals classify burns into three categories based on their severity and depth:

First-Degree Burns:

Known as superficial burns, these affect only the outer layer of skin, leading to redness and swelling. Typically, they require no medical intervention.

Second-Degree Burns:

These partial-thickness burns impact both the outer and underlying layers of skin, often resulting in blisters. They are usually more painful and may require medical attention, especially if blistering occurs.

Third-Degree Burns:

Full-thickness burns damage all layers of skin, leading to a white or charred appearance. Due to nerve damage, pain may be minimal. Such burns often necessitate skin grafting, which involves transferring healthy skin to promote healing.

Immediate Steps for Managing Thermal Burns

If you or someone else suffers a thermal burn, take these steps to assess the situation:

  • For severe burns, get medical help immediately.
  • If it’s a minor burn:
    • Cool the burn under cool (not cold) running water for about 10 minutes.
    • Remove any clothing or jewelry near the affected area.
    • Avoid applying lotions or breaking blisters to reduce infection risk.
    • Petroleum jelly or aloe vera can be used if the area is clean.
    • Loosely cover the burn with a sterile bandage.
    • Consider over-the-counter pain relievers to manage discomfort.

Treatment Options for Thermal Burns

For at-home burn care, replace the dressing daily until healing is complete. Additionally, monitor for infection signs, including:

  • Pus or fluid from the burn
  • Increasing pain over time
  • Changing size or color of the burn
  • Unexpected odor from the area
  • Fever

If any of these symptoms arise, seek medical assistance promptly.

When to Contact a Physician

While first-degree and many second-degree burns can be managed at home, professional medical assistance is vital in the following situations:

  • Burns larger than three inches
  • Burns on the face, hands, feet, or genital areas
  • Injuries affecting joints
  • Full circumferential burns on limbs or digits
  • Accompanied by systemic symptoms
Critical Note: Never attempt to treat third-degree burns at home. Ensure to call emergency services immediately while keeping the burned area elevated above the heart, avoiding removal of any adhering clothing.

Tips for Preventing Thermal Burns

With over 73% of burn injuries occurring at home, implementing precautionary measures is crucial. Here are some effective strategies:

  • Never leave cooking food unattended.
  • Use back burners and ensure pot handles face inward.
  • Keep oven mitts and pot holders accessible while cooking.
  • Turn off appliances after use to prevent accidental burns.
  • Keep hot beverages out of children's reach.
  • Adjust water heater settings to 120°F (49°C).
  • Always supervise young children during baths.

Conclusion

Thermal burns, resulting from contact with hot objects, are a pervasive risk in everyday life. They range from mild first-degree burns, characterized by redness, to severe third-degree burns, which can damage skin and require professional treatment. Prompt and appropriate care can alleviate suffering and prevent complications, underscoring the importance of preventive measures in our homes to safeguard ourselves and our loved ones from burn injuries.
