Electrical Burns: Symptoms, Risks and Medical Treatment

Electricity is an essential part of everyday life, but accidental contact with live wires, faulty appliances, damaged electrical connections, or high-voltage equipment can cause serious injuries. An electrical burn occurs when an electric current passes through the body or generates enough heat to damage the skin and underlying tissues. Unlike ordinary thermal burns, electrical burns can cause injuries that extend deep beneath the skin. In some cases, the visible wound may appear small even when muscles, nerves, blood vessels, or internal organs have been affected. Recognising electrical burn symptoms early and seeking immediate medical attention can help prevent serious complications. Whether the injury occurs at home, in a workplace, or due to accidental contact with exposed wiring, understanding the risks and appropriate treatment is important.  

What Are Electrical Burns?

Electrical burns are injuries caused by exposure to an electrical current. When electricity enters the body, it may travel through different tissues and generate heat, damaging cells along its pathway. The severity of an electrical injury depends on several factors, including:

• The voltage and strength of the electrical current.
• How long the person remains in contact with the electricity.
• The pathway the current takes through the body.
• The type of electrical source, such as household wiring or high-voltage equipment.
• The person’s overall health and the speed of medical treatment.

Electrical injuries may cause surface burns, deep tissue damage, or a combination of both. Some people develop visible entry and exit wounds, while others experience internal injuries without obvious skin damage.

Common Causes of Electrical Burns

Electrical injuries can happen in different environments. Some of the most common causes include:

1. Contact with Exposed Electrical Wires

Damaged insulation, loose connections, exposed cables, and faulty wiring can expose people to live electrical currents. Accidental contact may result in burns, muscle contractions, or severe electrical shock.

2. Faulty Household Appliances

Damaged electrical appliances, defective switches, broken plugs, and improperly maintained equipment can increase the risk of electrical accidents. Using electrical devices with wet hands or operating appliances near water can also create dangerous situations.

3. Workplace Electrical Accidents

Electricians, construction workers, maintenance personnel, and industrial employees may face electrical hazards while handling power equipment, electrical panels, machinery, and high-voltage installations. Inadequate safety equipment or failure to follow electrical safety procedures can increase the risk of serious injury.

4. High-Voltage Power Lines

Contact with overhead power lines, transformers, or electrical substations can cause extensive tissue damage and life-threatening complications. Even approaching certain high-voltage sources can be dangerous because electricity may arc through the air.

5. Lightning Strikes

Lightning is another source of electrical injury. A lightning strike can affect the heart, nervous system, skin, and other organs, sometimes causing immediate loss of consciousness or cardiac arrest.

8 Common Symptoms of Electrical Burns

Electrical burn symptoms depend on the amount of electrical exposure and the tissues affected. Some symptoms appear immediately, while others may become noticeable later.

1. Visible Burns on the Skin

Electrical injuries may leave burn marks where the current enters or exits the body. These wounds can appear as small, round, blistered, or discoloured areas. However, the size of the visible burn does not necessarily indicate the extent of internal damage.

2. Severe Pain or Burning Sensation

Some individuals experience intense pain around the affected area. Pain may also occur deeper in the muscles if electrical current has damaged underlying tissues. In certain cases, nerve damage can cause reduced sensation instead of pain.

3. Numbness and Tingling

Electrical current can affect nerves, leading to numbness, tingling, weakness, or unusual sensations in the hands, arms, legs, or other affected areas. Persistent changes in sensation require medical evaluation.

4. Muscle Spasms and Weakness

Electricity can trigger involuntary muscle contractions. These contractions may be strong enough to prevent a person from releasing an electrical source. Muscle injuries can also result in pain, swelling, and weakness after the initial accident.

5. Irregular Heartbeat

One of the most serious complications of electrical injury is an abnormal heart rhythm, medically known as an arrhythmia. An electrical current passing through the chest may interfere with the heart’s normal electrical activity and, in severe cases, cause cardiac arrest.

6. Difficulty Breathing

Electrical injuries may affect the nerves and muscles involved in breathing. Severe exposure can also cause loss of consciousness or cardiac arrest, leading to breathing difficulties. Any breathing problem following an electrical shock requires emergency medical assistance.

7. Dizziness or Loss of Consciousness

A person may experience confusion, dizziness, seizures, or temporary loss of consciousness following an electrical injury. These symptoms may indicate serious neurological or cardiovascular complications.

8. Swelling and Deep Tissue Damage

Electrical burns may damage muscles and other tissues beneath the skin. Swelling can develop around the affected area and sometimes increase pressure within muscle compartments, restricting blood flow. This condition, known as compartment syndrome, requires urgent medical assessment.

Serious Health Risks and Complications of Electrical Burns

Electrical burns are not limited to skin injuries. Depending on the severity of exposure, they can affect several vital body systems.

1. Internal Organ Damage

Electrical current can travel through the body and damage tissues that are not visible during an initial examination. Muscles, blood vessels, nerves, and internal organs may be affected. This is one reason why medical evaluation is important even when the external burn appears small.

2. Heart Rhythm Disturbances

Electrical exposure can interfere with the heart’s electrical signals, potentially causing dangerous arrhythmias. In severe cases, the person may experience cardiac arrest and require immediate resuscitation.

3. Kidney Damage

Severe muscle injury can release a protein called myoglobin into the bloodstream. This may damage the kidneys, particularly when associated with dehydration or extensive muscle breakdown. Doctors may monitor kidney function and urine output to identify complications early.

4. Nerve and Muscle Damage

Electrical injuries may affect nerve function and muscle strength. Some individuals experience ongoing numbness, weakness, pain, or difficulty moving the affected body part. Recovery depends on the extent of tissue damage and the treatment required.

5. Bone Fractures and Other Injuries

Strong muscle contractions or sudden falls during an electrical accident may cause fractures, joint injuries, or head and spinal trauma. Doctors may need to evaluate these associated injuries alongside the burn itself.

6. Infection and Delayed Wound Healing

Deep electrical burns can damage tissue and reduce blood supply to affected areas. This may increase the risk of infection and delay wound healing. Proper wound management and follow-up care are important to support recovery.

First Aid for Electrical Burns: What Should You Do Immediately?

The first priority during an electrical accident is protecting the injured person without putting yourself at risk. Follow these essential steps:

Step 1: Switch Off the Electricity

Immediately disconnect the power supply if it is safe to do so. Switch off the main power source or unplug the appliance when possible. Never touch a person who is still in contact with a live electrical source. You could also receive an electric shock. If the electricity cannot be switched off, do not approach the person or attempt to separate them from high-voltage equipment. Contact emergency services and the electricity provider.

Step 2: Call for Emergency Medical Assistance

Once the situation is safe, arrange immediate medical help. High-voltage injuries, loss of consciousness, breathing difficulties, abnormal heartbeat, seizures, and severe burns require emergency attention. Do not assume that the person is safe simply because they appear conscious or have only a small visible wound.

Step 3: Check Breathing and Responsiveness

After confirming that the electrical source is disconnected, check whether the person is conscious and breathing normally. If the person is unresponsive and not breathing normally, begin CPR if you are trained to do so, and follow the emergency dispatcher’s instructions. Use an automated external defibrillator (AED) if available.

Step 4: Cover the Burned Area

If there is a visible burn, cover it with a clean, dry, sterile dressing or cloth while waiting for medical assistance. Avoid applying pressure to the injured area.

Step 5: Prevent Further Injury

Keep the person comfortable and prevent unnecessary movement, particularly if they may have fallen or sustained a spinal injury. Do not remove clothing stuck to the burned skin or apply home remedies.

What Should You Avoid After an Electrical Burn?

• Do not touch the injured person before the electrical source is disconnected.
• Do not approach fallen high-voltage wires.
• Do not apply oil, toothpaste, butter, or creams to the burn.
• Do not break blisters or remove damaged skin.
• Do not delay hospital evaluation because the wound looks minor.
• Do not attempt to treat deep electrical injuries at home.

Important: Electrical injuries require prompt medical assessment even when visible skin damage is limited. Do not delay emergency care to perform home treatment.

How Are Electrical Burns Diagnosed?

Diagnosing an electrical burn involves more than examining the visible wound. Doctors assess the person’s exposure history, symptoms, vital signs, and possible internal injuries. Depending on the severity of the accident, the following investigations may be recommended.

1. Physical Examination

The doctor examines the skin for burn wounds, swelling, tissue damage, and possible entry and exit points. The assessment may also include checking muscle strength, sensation, circulation, and movement in the affected areas.

2. Electrocardiogram (ECG)

An ECG records the electrical activity of the heart. It may be performed to identify abnormal heart rhythms or other changes following electrical exposure. Further heart monitoring may be recommended depending on the injury and initial findings.

3. Blood Tests

Blood investigations may help identify muscle damage, electrolyte abnormalities, and changes in kidney function. Tests such as creatine kinase (CK), kidney function markers, and electrolyte measurements may be recommended in significant electrical injuries.

4. Urine Tests

Urine testing may help detect myoglobin released during severe muscle damage and assess possible kidney complications.

5. Imaging Tests

X-rays, ultrasound, CT scans, or other imaging investigations may be recommended when doctors suspect fractures, internal injuries, or significant tissue damage. Not every patient requires all these investigations. The doctor determines the appropriate tests based on the type and severity of the injury.

Medical Treatment for Electrical Burns

Electrical burn treatment depends on the depth of the injury, the organs affected, and the patient’s overall condition. Some patients require wound care and observation, while severe injuries may need intensive treatment or surgery.

1. Immediate Emergency Stabilisation

Doctors first assess breathing, circulation, heart function, and neurological status. Patients with serious injuries may require oxygen support, cardiac monitoring, resuscitation, or other emergency interventions.

2. Intravenous Fluids

Significant electrical injuries can cause extensive muscle damage and fluid shifts. Intravenous fluids may be given to maintain circulation and support kidney function. Fluid requirements are carefully monitored according to the patient’s condition and urine output.

3. Burn Wound Management

The medical team evaluates the depth and extent of the burn before deciding on appropriate wound care. Treatment may involve:

• Cleaning and dressing the wound.
• Removing dead or damaged tissue when necessary.
• Using appropriate wound-care products.
• Monitoring for infection.
• Providing pain management.

4. Surgical Treatment

Deep electrical burns may require surgical intervention when significant tissue damage is present. Depending on the injury, procedures may include:

• Surgical removal of damaged tissue (debridement).
• Fasciotomy to relieve dangerous pressure within muscle compartments.
• Skin grafting to cover areas where skin has been severely damaged.
• Reconstructive procedures to restore function and appearance.

Surgery is recommended according to the extent and progression of the injury.

5. Heart and Kidney Monitoring

Patients with significant electrical exposure may require monitoring for abnormal heart rhythms, muscle breakdown, and kidney complications. The medical team may repeat ECGs, blood investigations, and urine assessments depending on clinical findings.

6. Rehabilitation and Follow-Up Care

Recovery from an electrical burn may take time, particularly when muscles, nerves, or joints are affected. Physiotherapy, wound follow-up, scar management, and rehabilitation may help improve movement and restore daily functioning. Some patients may also benefit from psychological support following a traumatic electrical accident.

How Can Electrical Burns Be Prevented?

Many electrical accidents can be reduced through simple safety precautions at home and in the workplace.

• Replace damaged wires, plugs, and electrical switches.
• Never operate electrical appliances with wet hands.
• Keep electrical equipment away from water.
• Use appropriate safety equipment when handling electrical installations.
• Keep children away from exposed sockets and damaged cables.
• Avoid overloading electrical outlets.
• Hire qualified electricians for wiring repairs and maintenance.
• Follow workplace electrical safety procedures.
• Maintain a safe distance from fallen power lines and electrical transformers.

Prevention is particularly important in households with young children and workplaces where employees regularly handle electrical equipment.

When Should You Visit a Hospital After an Electrical Burn?

You should seek medical evaluation after any significant electrical shock or suspected electrical burn, even if the skin appears normal. Immediate emergency care is especially important if you notice:

• Visible burn wounds or damaged skin.
• Chest pain or an irregular heartbeat.
• Difficulty breathing.
• Muscle spasms or severe pain.
• Numbness or weakness.
• Dizziness, confusion, or loss of consciousness.
• Seizures.
• A fall or suspected fracture following the shock.
• Exposure to high-voltage electricity or lightning.

Early assessment helps doctors identify hidden injuries and decide whether observation, investigations, or specialised treatment is necessary.
