About Burn Injuries

Overview

Burn injuries refer to damage caused to the skin or other tissues due to exposure to heat, chemicals, electricity, or radiation. They can occur as a result of direct or indirect contact with high temperatures, electric currents, cold objects, corrosive substances, or highly radioactive materials. The severity of burn injuries depends on the depth and size of the wounds. They can be classified into four degrees based on the depth of tissue damage. Additionally, the size of burn injuries is often measured by calculating the percentage of the burned area compared to the total body surface area (TBSA). Burn injuries can be classified as minor or major based on their size and depth. It is important to note that older adults may experience more serious complications from burn injuries compared to younger adults.

Causes and Risk Factors

Burn injuries happen due to a complicated mix of different factors. The basic reasons behind the complications associated with burn injuries include:

• Burns cause the release of many chemicals within the body that cause high levels of inflammation. This inflammation affects every system of the body and can cause shock.
• When burn injuries involve large areas of the body, the body cannot protect itself against infection.
• If the airway is involved, there can be swelling that can require placement on a breathing machine (ventilator).
• Burn injuries cause coagulative necrosis—the death of skin and underlying tissues. The amount of damage depends on the temperature, energy transmitted, and how long the exposure lasts.
• A burn injury site can be divided into three zones:
  • The zone of coagulation (necrosis): where the most severe damage occurs
  • The zone of stasis: where there is moderate damage and reduced blood flow
  • The zone of hyperemia: where blood flow increases to healthy tissues.
• Burns that cover more than 30% of total body surface area (TBSA) can cause widespread effects, including low blood volume, the release of inflammatory mediators, burn shock, heart problems, fluid leakage (plasma extravasation), changes in blood flow, poor tissue perfusion (where blood isn’t flowing well enough to certain parts of the body), and a higher risk of multiple organ failure.

Non-modifiable risk factors for burn injuries cannot be changed or controlled. This includes:

• Age: Young children and older adults are more susceptible to burn injuries.

Modifiable risk factors for burn injuries can be influenced or changed. These include:

• Environmental factors: Exposure to heat sources, chemicals, electricity, or radiation
• Unsafe behaviors: Mishandling flammable substances or engaging in risky activities

Remember that prevention is key in reducing the risk of burn injuries. Always prioritize safety measures and seek professional advice for specific situations.

Symptoms

Early symptoms of burn injuries:

• Redness Blisters
• Intense pain or skin sensitivity
• Skin that looks white, very deep red, or very dark brown

Symptoms that may occur with later stages, progression, or higher severity of burn Injuries:

• Skin discoloration (white, grey, black, brown, yellow)
• Dry, leathery, or waxy skin
• Swelling
• Lack of pain due to damage to nerve endings
• Shock (body's inflammatory response causing damage to tissues and organs)
• Infections (severe damage to the skin making the body more susceptible to pathogens)

It is important to note that depression is a common symptom experienced by patients with burn injuries. It can occur alongside physical symptoms and should be addressed for the overall well-being of the patient. Additionally, pain is a major symptom in burn patients and can affect them emotionally and socially. Opioids are commonly used for moderate to severe burn pain but may have dependency issues with long-term use and other side effects. Consult with a healthcare professional for proper management and treatment options.

Diagnosis

During the diagnosis of burn injuries, healthcare providers commonly perform the following examinations, tests, and procedures:

• Physical examination: The healthcare provider will look for physical signs of a burn injury, such as pain, swelling, redness or other changes in skin color.
• Lab tests: Blood work may be performed especially when there is smoke inhalation associated with burns or if the burns involve a large area of the body.
• Imaging studies: X-rays or CT scans may be done to evaluate the extent of the burn injury and assess any underlying damage to bones or internal organs.
• Clinical procedures: Depending on the symptoms and severity of the burn injury, various clinical procedures may be performed, such as removal of some of the damaged tissue.

To determine the stage or severity of burn injuries, additional examinations and tests may include:

• Burn area assessment: Healthcare providers may use techniques like digital camera photography or specialized software to measure and document the size of the burn area.
• Burn depth assessment: Techniques such as laser-Doppler imaging can be used to check blood flow in burned tissue and determine how deep the burn injury is.

It's important to note that these are general descriptions of examinations, tests, and procedures commonly used in diagnosing and assessing burn injuries. The specific approach may vary depending on individual circumstances. Always consult with your healthcare provider for personalized advice.

Treatment Options

The goals of treatment for burn injuries include pain relief, prevention of infection, promotion of rapid healing, and cosmetic procedures to improve the appearance of the wounds.

Here's a breakdown of some treatment approaches to reach these goals:

Medication types:

• Topical medicines: Help improve survival and minimize the incidence of burn wound sepsis—a dangerous infection that starts in a burn wound and spreads through the body.
• Antibiotics: Used to prevent or treat infections that may occur in burn wounds

Therapies:

• Dressing options: Different types of dressings can be used to treat burns, depending on how deep the burn is and how much area is affected.
• Psychological interventions: Address depression and stress reactions among burn trauma survivors to help with physical and mental recovery and improve quality of life.

Medical procedures:

• Emergency treatment: The first step is to make sure the patient is stable, focusing on keeping their breathing and heart working well before treating the wound.
• Wound evaluation: This is checking the wound's condition to decide on the best way to treat it.
• Debridement: This is the process of cleaning the burn wound by removing any dirt, dead tissue, and bacteria to lower the risk of infection.
• Slough removal: This is clearing away dead tissue from the wound, which helps the wound heal better.

Lifestyle changes:

• Proper wound care: Keeping the wound clean, preventing the growth of harmful bacteria, and creating an environment that supports healing.
• Pain management: Reducing pain to the injured area through appropriate pain medications or techniques.
• Rehabilitation exercises: Preventing joint stiffness and contractures (tightening of muscles, tendons, or skin that makes movement difficult) by engaging in recommended exercises.

It's important to note that specific treatment recommendations may vary depending on the severity and location of the burn injury. Always consult with a healthcare professional for personalized advice.

Medication dosing may be affected by many factors. Check with your healthcare professional about dosing for your individual situation. Other side effects can occur. Check with your healthcare professional or read the information provided with your medication for additional side effect information.
