Electrical Burn Injury Management

Introduction to Electrical Burn Injuries

• Electrical burn injuries require close cardiac monitoring due to the risk of cardiac arrhythmias, which are a primary cause of immediate death from electrocution, as recommended by the American Heart Association 1, 2

Severity Assessment and Characteristics

• Electrical burns vary widely in severity, ranging from mild tingling sensations to fatal injuries, with the extent of injury often not correlating with visible skin damage, according to the American College of Cardiology 3, 4

Cardiac Complications and Monitoring

• Cardiopulmonary arrest is the primary cause of immediate death from electrocution, making cardiac monitoring essential, as stated by the American Heart Association 1
• Cardiac arrhythmias including ventricular fibrillation, ventricular asystole, and ventricular tachycardia may result from exposure to both low and high-voltage current, as reported by the American College of Cardiology 1, 2
• The frequency of alternating current increases the likelihood of current flow through the heart during the vulnerable period of the cardiac cycle, potentially precipitating ventricular fibrillation, according to the American Heart Association 1

Management Approach

• Initial management includes ensuring scene safety by turning off the power source before approaching the victim, as recommended by the American College of Surgeons 4, 5
• Once power is off, assess the victim who may need CPR, defibrillation, and treatment for shock and thermal burns, according to the American Heart Association 4
• Early intubation should be considered for patients with evidence of extensive burns, particularly those involving the face, mouth, or anterior neck, as stated by the American College of Surgeons 2
• Rapid IV fluid administration is indicated for victims with significant tissue destruction to counteract shock and correct ongoing fluid losses, as recommended by the American College of Emergency Physicians 1, 2

Common Pitfalls and Caveats

• Underestimating the severity of electrical injuries based on visible skin damage can lead to delayed recognition of serious complications, as warned by the American College of Cardiology 4
• Failure to monitor cardiac function can result in missed arrhythmias, which are a significant cause of mortality, according to the American Heart Association 1, 2

Management of Electrical Injury

Fluid Management

• The American College of Critical Care recommends initiating therapy with crystalloid isotonic fluids (0.9% saline solution) as the first line for patients with electrical injuries who show signs of shock 6, 7
• Isotonic crystalloid fluids should be used to avoid hypotonic solutions like lactated Ringer's, which can increase tissue edema in patients with electrical injuries 6
• Fluids should be administered using a fluid challenge technique, with boluses of 250-1000 ml and reevaluation after each bolus 8

Resuscitation Goals and Monitoring

• The response to fluid resuscitation should be evaluated by measuring lactate levels (aiming for a 20% reduction in the first hour) and clinical signs of tissue perfusion 8
• The use of vasopressors (such as norepinephrine) should be considered if hypotension persists despite adequate fluid resuscitation 8
• Fluid resuscitation should be interrupted when no improvement in tissue perfusion is observed in response to volume loading 8
• Signs of fluid overload, such as pulmonary edema, should be monitored, especially in patients with limited access to mechanical ventilation 8

Electrical Burn Care Planning

Assessment and Management

• The Lund-Browder method is recommended for documenting the total body surface area (TBSA) affected, as it is more accurate than other assessment methods 9, 10

Management of Electrocution Burns

Burn Assessment and Management

• The American Burn Association recommends using the Lund-Browder chart for total body surface area (TBSA) measurement, as it is the most accurate method, preventing both overtriage and undertriage that can increase morbidity and mortality 11, 12, 13, 14, 15
• The open hand (palm and fingers) represents approximately 1% TBSA and is a practical alternative that limits overvaluation 11, 12, 13, 14, 15
• Smartphone applications (e.g., E-Burn) can facilitate TBSA assessment 11, 12, 13, 14, 15

Specialist Referral and Transfer

• The American College of Surgeons recommends referral to a burn specialist immediately to determine whether the patient should be admitted to a burns center 11, 12, 13, 14, 15
• Telemedicine should be used to improve initial assessment when no burns specialists are readily available, as it reliably improves TBSA measurement and prevents inappropriate transfers 11, 12, 13, 15
• Direct admission to a burns center should be preferred if hospitalization is indicated, as this reduces time to excision, duration of mechanical ventilation, and improves survival 11, 12, 13, 16, 15

Surgical Considerations

• The American Burn Association recommends escharotomy if deep burns induce compartment syndrome in the limbs or trunk that compromises airways, respiration, and/or circulation 11, 12, 13, 14, 15
• Ideally, escharotomy should be performed in a burns center by an experienced provider 11, 12, 13, 14, 15
• Circumferential third-degree burns can cause acute limb ischemia with neurological disorders, thoracic/abdominal compartment syndrome with decreased cardiac output and pulmonary compliance, hypoxia, hypercapnia, acute renal failure, and mesenteric ischemia 16

Electrical Burn Treatment Guidelines

Introduction to Electrical Burn Care

• The American Heart Association recommends that burns involving the face, hands, feet, and genitals may require surgical intervention to prevent permanent disability and should be treated in a specialized burn center 17

Pain Management for Electrical Burns

• The American Society of Anesthesiologists suggests administering over-the-counter analgesics such as acetaminophen or NSAIDs for burn pain, as they are well tolerated and generally recommended 17
• The British Journal of Anaesthesia recommends considering multimodal analgesia with titrated intravenous ketamine combined with other analgesics for severe burn-induced pain 18
• All analgesic medications must be titrated based on validated comfort and analgesia assessment scales, as recommended by the Anaesthesia society 18

Electrical Burn Management

Classification and Severity

• All electrical burns are classified as severe burns requiring immediate referral to a specialized burn center, according to the American Burn Association 19, 20, 21
• Electrical burns meet severe burn criteria when they involve high-voltage electricity, or low-voltage electricity combined with total body surface area (TBSA) >10% or deep burns 3-5% 19, 20, 21
• For children, any electrical burn automatically qualifies as severe 19, 20, 21

Triage and Referral

• The American College of Surgeons recommends immediate referral to a burn specialist to determine admission to a burns center, as direct admission reduces time to excision, duration of mechanical ventilation, and improves survival 19, 20, 21
