Burns: Types, Symptoms, Causes, Risk Factors, Treatments and Recommendations

Burns

Burns are injuries to the skin or other tissues which caused by various factors, such as heat, electricity, chemicals, radiation, or friction. Burns can differ in severity, ranging from mild superficial burns to severe deep burns that can be life-threatening. Normally, they result in damage to the affected tissues, mostly leading to burning sensation, severe pain, inflammation, and sometimes loss of function.

What are the different types of Burns?

Burns can be categorized into different types based on their severity and the depth of tissue damage. The most commonly recognized classification divides burns into four main types:

1. First-Degree Burns (Superficial Burns): These burns affect only the outermost layer of the skin, commonly known as the epidermis. They typically cause redness, pain, and minor swelling. First-degree burns are often caused by brief exposure to heat, hot liquids, or sunburns. They generally heal within a week without scarring.

2. Second-Degree Burns (Partial-Thickness Burns): Second-degree burns extend beyond the epidermis and affect the underlying layer of skin called the dermis. They can be further divided into two subcategories:

a. Superficial Partial-Thickness Burns: These burns involve the upper layers of the dermis and result in blistering, redness, pain, and swelling. They may take several weeks to heal and can leave temporary pigment changes or scars.

b. Deep Partial-Thickness Burns: These burns extend deeper into the dermis and may appear white, blotchy, or charred. They often result in intense pain and can take several weeks to heal, often requiring medical intervention such as skin grafting.

3. Third-Degree Burns (Full-Thickness Burns): Third-degree burns extend through the entire thickness of the skin, affecting both the epidermis and dermis. The burned area may appear white, blackened, or leathery. Third-degree burns usually result in numbness or loss of sensation because the nerve endings are damaged. These burns require immediate medical attention and often necessitate surgical intervention, such as skin grafting.

4. Fourth-Degree Burns: In some classifications, fourth-degree burns are mentioned to describe burns that extend beyond the skin layers and affect the underlying structures like muscles, tendons, or bones. These burns are severe and can be life-threatening, requiring emergency medical care.

What are the common symptoms of various types of burns?

The symptoms of a burn can vary depending on the severity and depth of the burn. Here are common symptoms associated with different degrees of burns:
1. First-Degree Burns (Superficial Burns):
  • Redness of the skin
  • Pain or discomfort
  • Swelling
  • Mild to moderate tenderness
2. Second-Degree Burns (Partial-Thickness Burns):
  • Blistering of the skin
  • Severe pain
  • Redness and swelling
  • Moist or weeping appearance
  • Peeling skin
  • Possible scarring
3. Third-Degree Burns (Full-Thickness Burns):
  • White, brown, black, or charred appearance of the skin
  • Hard, dry, or leathery texture
  • Numbness or loss of sensation in the affected area
  • Severe pain or no pain (nerve endings may be damaged)
  • Swelling
  • Difficulty breathing (if the burn involves the airway)
  • Possible scarring

What are the main probable contributing factors of burns?

Burns can be caused by various factors and sources. Here are some common causes of burns:
1. Heat Sources:
  • Fire or flames: Contact with open flames, explosions, or flammable materials.
  • Hot objects: Touching hot surfaces, such as metal, glass, or cooking utensils.
  • Scalding liquids: Contact with hot water, steam, or boiling liquids.
  • Thermal burns: Exposure to extreme heat from sources like hot air or hot surfaces.
2. Electrical Sources:
  • Electric shock: Contact with exposed live wires or faulty electrical equipment.
  • Lightning strikes: Direct or indirect contact with lightning.
3. Chemical Sources:
  • Contact with corrosive or caustic substances: Exposure to acids, alkalis, strong cleaning agents, or industrial chemicals.
  • Inhalation of toxic fumes: Breathing in harmful gases or smoke from chemicals or burning materials.
4. Radiation:
  • Sunburn: Overexposure to ultraviolet (UV) radiation from the sun or tanning beds.
  • Radiation therapy: Treatment involving high-energy radiation for medical purposes.
5. Friction: 
  • Abrasion: Rubbing the skin against a rough surface, causing friction burns.
  • Road rash: Skin injuries resulting from motorcycle or bicycle accidents, or sliding on a hard surface.
6. Cold Sources:
  • Frostbite: Prolonged exposure to extremely cold temperatures, leading to tissue damage.

What are the complications associated with burns?

Burns can lead to various complications, especially in more severe cases. To give more focus on some points like prompt medical attention, proper wound care, and ongoing follow-up with healthcare professionals are essential to prevent and manage complications associated with burns. Here are some common complications associated with burns:
  • Infection: Burned skin is vulnerable to infection. Bacteria can enter through open wounds or compromised skin barriers, leading to localized infections or potentially life-threatening systemic infections like sepsis. Some common signs of infection include increased pain, redness, swelling, warmth, discharge, or fever.
  • Scarring and Contractures: Severe burns can result in the formation of scar tissue, which can lead to restricted movement and the development of contractures. Contractures occur when the scar tissue tightens, causing the skin, muscles, or joints to become immobile. Physical therapy and scar management techniques are often employed to minimize contractures.
  • Respiratory Issues: Burns involving the face, neck, or chest can affect the airway, leading to breathing difficulties or inhalation injuries from smoke, toxic fumes, or chemical inhalation. Inhalation injuries can damage the lungs and respiratory tract, potentially causing respiratory distress or complications like pneumonia.
  • Circulatory Problems: Severe burns can damage blood vessels, leading to impaired circulation. This can result in poor wound healing, tissue death (necrosis), or the need for amputation in severe cases.
  • Hypovolemia and Shock: Extensive burns can cause significant fluid loss from the damaged skin, leading to hypovolemia (low blood volume). This can result in hypoperfusion, where organs and tissues do not receive enough blood flow which ultimately leading to shock. Shock is a life-threatening condition requiring immediate medical intervention.
  • Electrolyte Imbalance: Burns can disrupt the balance of electrolytes (such as sodium, potassium, and chloride) in the body, leading to imbalances that can affect vital functions and lead to complications such as cardiac arrhythmias or muscle weakness.
  • Psychological and Emotional Impact: Burn injuries can have a profound psychological and emotional impact on individuals. They may experience anxiety, depression, post-traumatic stress disorder (PTSD), or body image issues. Psychological support and counseling can play a vital role in the recovery and well-being of burn survivors.

What are the potential risk factors related to burns?

Several risk factors can increase a person's vulnerability to burns. These factors can include:
  • Age: Young children and older adults are at a higher risk of burns. Children have less awareness of potential dangers, while older adults may have reduced mobility or sensitivity.
  • Occupation: Certain occupations, such as firefighters, industrial workers, or chefs, can increase the risk of occupational burns due to the nature of the work and exposure to heat, chemicals, or flames.
  • Living or working conditions: Individuals living in or working in environments where fire hazards or flammable materials are present, for examples, factories, laboratories, or construction sites, face an increased risk of burns.
  • Cooking: Accidents during cooking, for instances, hot oil splatters or contact with hot surfaces or open flames, can lead to burns.
  • Substance abuse: Alcohol or drug use can impair judgment and coordination, increasing the likelihood of accidents involving fire, hot substances, or dangerous situations.
  • Mobility or cognitive impairments: Individuals with physical limitations or cognitive impairments may have difficulty avoiding burn hazards or recognizing dangerous situations.
  • Medical conditions: Certain medical conditions, such as diabetes, peripheral neuropathy, or impaired sensation, can reduce a person's ability to detect or respond to burns.
  • Medications: Some medications can increase sensitivity to the sun, making individuals more susceptible to sunburns.
  • History of burns: Individuals who have previously experienced burn injuries may be at a higher risk of future burns.
  • Environmental factors: Living in areas prone to wildfires or experiencing natural disasters like earthquakes or house fires can increase the risk of burn injuries.

How to calculate the severity of burns?

To calculate the severity of a burn, several methods can be used by healthcare professionals. The most commonly employed method is the Rule of Nines, which estimates the percentage of the total body surface area (TBSA) affected by the burn. This calculation is particularly useful for determining the need for specialized medical care, fluid resuscitation, and overall prognosis. The Rule of Nines divides the body into different regions, each representing approximately 9% or a multiple of 9% of the TBSA:

  • Head and Neck: 9% (front and back of the head each)
  • Each Upper Limb (Arm): 9% (front and back of each arm)
  • Front Torso (Chest and Abdomen): 18%
  • Back Torso (Back and Buttocks): 18%
  • Each Lower Limb (Leg): 18% (front and back of each leg)
  • Perineum (Genital area): 1%
Using this method, one can estimate the TBSA affected by adding up the percentages of the burn areas involved. It's important to note that this method provides an approximation and may not be precise for every individual case.

In addition to the Rule of Nines, there are more detailed methods available, such as the Lund and Browder Chart, which takes into account the different proportions of body surface area at various ages and can provide a more accurate estimation for burns in children.

What are the numerous options to treat burns?

The treatment of burns depends on the severity and extent of the injury. Here are general guidelines for burn treatment, but it's important to seek immediate medical attention for severe burns or burns involving sensitive areas like the face, hands, feet, genitals, or major joints:
1. First-Aid Steps:
  • Ensure safety: Remove the person from the source of the burn and eliminate any ongoing danger.
  • Assess the burn: Determine the severity of the burn and the affected area.
  • Cool the burn: For first-degree and some second-degree burns, run cool (not cold) water over the burn for 10-20 minutes or apply cool, wet compresses to ease pain and reduce swelling. Do not use ice.
  • Cover the burn: Protect the burn with a sterile non-stick dressing or clean cloth to prevent infection.
2. Pain Management: Certain over-the-counter pain relievers like acetaminophen or ibuprofen or diclofenac can help to manage pain. For this purpose, follow the appropriate dosage instructions.
3. Medical Evaluation: Seek medical attention for severe burns, deep or extensive burns, burns involving the face, hands, feet, genitals, or major joints, or if the person is experiencing difficulty in breathing or signs of shock.
4. Wound Care and Dressing: For second-degree burns, follow medical advice on whether to keep the blister intact or drain it. Clean the burn gently with mild soap and water, and apply a sterile dressing or prescribed ointment. Along with these, it is advisable not to apply adhesive bandages directly to the burn.
5. Tetanus Shot: Check with a healthcare professional if a tetanus shot is necessary, especially if the burn is deep, contaminated, or caused by a dirty or rusty object.
6. Antibiotics: Prescription antibiotics may be necessary to prevent or treat infection, particularly for deep burns or burns with significant tissue damage.
7. Specialized Treatments: For severe burns, specialized burn centers may provide advanced treatments like wound debridement, skin grafting, or other surgical interventions.
8. Rehabilitation and Support: For extensive burns, rehabilitation and support services such as physical therapy, occupational therapy, counseling, or support groups may be beneficial for recovery and coping with emotional challenges.
