Electrical Burns: Understanding the Severity and Treatment

Electricity powers our modern world, but it also presents a significant hazard. Contact with electrical current can cause devastating injuries, known as electrical burns. These burns differ significantly from thermal burns, often causing extensive internal damage that isn’t immediately apparent. According to the Electrical Safety Foundation International (ESFI), approximately 1,000 deaths per year in the United States are attributed to electrical injuries. Understanding the nature, severity, and proper treatment of electrical burns is crucial for preventing further harm and ensuring the best possible recovery.

What are Electrical Burns?

An electrical burn is a tissue injury resulting from electricity passing through the body. Unlike thermal burns caused by heat, electrical burns occur when the body becomes part of an electrical circuit, causing the current to travel through tissues and generate heat. The severity of an electrical burn depends on several factors:

Voltage: Higher voltage generally leads to more severe burns.
Type of Current: Alternating current (AC) is often more dangerous than direct current (DC) because it can cause muscle contractions, making it difficult to release the electrical source.
Pathway: The path the electricity takes through the body determines which tissues and organs are affected.
Duration of Contact: The longer the contact, the greater the damage.
Resistance: Tissues with higher resistance to electrical current, such as bone, tendon, and fat, experience more heat damage. Muscle, with its high volume, often carries the bulk of the current, leading to significant internal damage.

Electrical injuries are categorized into four main types:

True Electrical Injury: Occurs when an electrical current passes directly through the body.
Flash Injury: Caused by an arc flash, resulting in superficial burns as the current doesn’t pass through the body.
Flame Injury: Occurs when an electrical arc ignites clothing or nearby materials, leading to thermal burns.
Lightning Injury: Results from extremely high-voltage, short-duration electrical energy.

Severity and Classification of Electrical Burns

Electrical burns are classified based on the depth of tissue damage, similar to thermal burns:

First-Degree Burns: Affect only the epidermis (outer layer of skin). They are characterized by redness, pain, and minor swelling, typically healing within a week.
Second-Degree Burns: Involve the epidermis and dermis (second layer of skin). Symptoms include pain, redness, blistering, and potential oozing. Healing can take several weeks.
Third-Degree Burns: Extend through the dermis and into the subcutaneous tissue (innermost layer). These burns can appear white or charred, with a leathery texture. Nerve damage may result in a lack of pain in the affected area. Third-degree burns require immediate medical attention and often skin grafting.

However, the external appearance of an electrical burn can be deceptive. Significant internal damage may exist even when the skin appears only mildly affected. This is because electricity follows the path of least resistance within the body, potentially damaging deep tissues, muscles, and organs along the way.

Recognizing the Signs and Symptoms

Symptoms of electrical burns can vary widely depending on the severity and extent of the injury. Common signs and symptoms include:

Visible Burns: Entrance and exit wounds on the skin, often small but deep.
Loss of Consciousness: Even a momentary loss of consciousness warrants immediate medical evaluation.
Confusion or Disorientation: Neurological effects can cause confusion, dizziness, or headache.
Cardiac Arrhythmias: Irregular heartbeats or cardiac arrest can occur due to electrical interference with the heart’s electrical activity.
Muscle Pain and Contractions: Involuntary muscle contractions can be forceful enough to cause fractures or dislocations.
Numbness or Tingling: Nerve damage can lead to numbness, tingling, or weakness in the affected area.
Seizures: Electrical shock can disrupt brain function, leading to seizures.
Breathing Difficulties: Lung injury or neurological damage can cause shortness of breath.
Red or Red-Black Urine: This may indicate myoglobinuria, a condition caused by muscle breakdown that can lead to kidney damage.

First Aid and Immediate Care

Providing immediate and appropriate first aid is crucial in the event of an electrical burn. Follow these steps:

Ensure Safety: Do not touch the injured person if they are still in contact with the electrical source. Turn off the power at the source (e.g., circuit breaker) if possible. If you cannot turn off the power, use a dry, non-conductive object (such as a wooden broom handle, cardboard, or rubber mat) to separate the person from the electrical source.
Call for Help: Call 911 or your local emergency number immediately. Electrical burns can cause life-threatening complications, so prompt medical attention is essential.
Assess the Victim: Check for responsiveness, breathing, and pulse. If the person is not breathing or does not have a pulse, begin CPR immediately.
Treat Burns: Cover any burned areas with a sterile gauze bandage or a clean cloth. Do not apply ointments or break blisters.
Prevent Shock: Keep the person warm and lying down, elevating their feet and legs slightly.

What to Avoid:

Do not approach high-voltage wires until the power is turned off. Stay at least 50 feet away from downed power lines.
Do not remove clothing or try to clean the burned area.
Do not use a blanket or towel to cover the person, as loose fibers can stick to the burn.

Hospital Treatment and Management

In the emergency department, doctors will conduct a thorough evaluation to assess the extent of the electrical burn and any associated injuries. This may include:

Cardiac Monitoring: To detect and manage any heart rhythm abnormalities.
Laboratory Tests: Blood tests to check for muscle damage (creatine kinase), kidney function, and electrolyte imbalances. Urinalysis to detect myoglobinuria.
Imaging Studies: X-rays to check for fractures or dislocations. CT scans to evaluate internal organ damage or head trauma.
Burn Assessment: Determining the degree and extent of the burn to guide treatment.

Treatment strategies focus on:

Airway Management: Ensuring adequate oxygenation and ventilation, potentially requiring intubation.
Fluid Resuscitation: Administering intravenous fluids to prevent shock and maintain kidney function.
Wound Care: Cleaning and dressing the burn wounds to prevent infection.
Pain Management: Providing pain relief medication.
Surgical Intervention: Debridement (removal of damaged tissue) and skin grafting may be necessary for severe burns. Fasciotomy (surgical incision to relieve pressure) may be required to treat compartment syndrome caused by tissue swelling.

Potential Complications and Long-Term Effects

Electrical burns can lead to a variety of complications, both immediate and long-term:

Cardiac Arrest: Electrical current can disrupt the heart’s rhythm, leading to cardiac arrest.
Neurological Damage: Nerve damage can cause chronic pain, numbness, tingling, weakness, seizures, and cognitive impairments.
Muscle Damage: Rhabdomyolysis (muscle breakdown) can lead to kidney failure.
Compartment Syndrome: Swelling within muscle compartments can compromise blood flow and nerve function, potentially requiring fasciotomy.
Infection: Burned skin is more susceptible to bacterial infections.
Scarring and Contractures: Deep burns can result in significant scarring and contractures (tightening of the skin), limiting movement.
Amputation: Severe tissue damage may necessitate amputation of affected limbs.
Cataracts: Electrical injuries can cause cataracts to develop in the eyes.
Psychological Trauma: Electrical burns can be emotionally traumatic, leading to post-traumatic stress disorder (PTSD), anxiety, and depression.

Legal Considerations

If an electrical burn is caused by someone else’s negligence, the victim may have grounds for a personal injury lawsuit. Potential liable parties may include:

Employers: For workplace electrical injuries due to unsafe conditions or inadequate training.
Utility Companies: For injuries caused by downed power lines or faulty equipment.
Manufacturers: For injuries caused by defective electrical products.
Property Owners: For injuries caused by hazardous electrical wiring on their property.

An experienced personal injury attorney can help victims understand their legal rights and pursue compensation for medical expenses, lost wages, pain and suffering, and other damages.

Prevention Strategies

Preventing electrical burns requires awareness, caution, and adherence to safety guidelines:

At Home:
- Use safety covers on electrical outlets, especially if children are present.
- Inspect electrical cords regularly for damage and replace them if frayed or worn.
- Never overload electrical outlets or extension cords.
