What is the appropriate management of a child with an electrical injury?

Management of Electrical Injury in Children

All children with electrical injuries require immediate scene safety assessment, followed by standard pediatric resuscitation protocols with cardiac monitoring, and all victims need medical evaluation regardless of apparent injury severity because internal damage may not be visible externally. 1, 2

Immediate Scene Safety and Initial Assessment

Scene Safety (Critical First Step)

• Do not touch the child while power is on - you become part of the circuit 1
• Turn off power at the source (circuit breaker/fuse box for household injuries)
• For high-voltage injuries (fallen power lines): immediately call 911/fire department and do not approach until power is confirmed off by trained personnel
• All materials conduct electricity at high voltage - do not use any object (including wood) to remove wires until power is off 1

Primary Survey and Resuscitation

Once scene is safe, assess for life-threatening conditions:

Cardiac arrest is the primary cause of immediate death from electrocution 1. The child may require:

• CPR and defibrillation for cardiac arrest
• Prolonged resuscitation may be warranted - case reports document good neurologic outcomes after up to 70 minutes of CPR in electrical injury 2
• Cardiac arrhythmias can include ventricular fibrillation, ventricular tachycardia, atrial fibrillation, and pulseless electrical activity 2
• Respiratory arrest may occur from injury to the brainstem respiratory center or tetanic contraction/paralysis of respiratory muscles 1

Comprehensive Medical Evaluation

Every child with electrical shock requires medical assessment because the extent of injury may not be apparent externally 1. This is critical because:

Hidden Injury Patterns

• Thermal burns occur at entry and exit points AND along the internal pathway of current through the body 1
• High-voltage injuries cause severe deep tissue damage despite potentially minimal external burns 3
• Internal injuries include: cardiac damage, rhabdomyolysis, compartment syndrome, vascular thrombosis, neurological injury, and renal dysfunction 4, 5

Voltage-Specific Considerations

Low-Voltage Injuries (<1000V):

• Predominantly household exposures in younger children (mean age ~4 years) 3
• Smaller total body surface area involvement (mean ~3%) 3
• Shorter hospitalization (mean ~9 days) 3
• Lower surgical burden but still require full evaluation 3

High-Voltage Injuries (≥1000V):

• Typically outdoor exposures in older children (mean age ~10 years) 3
• Significantly larger burns (mean ~20% TBSA) 3
• Prolonged hospitalization (mean ~27 days) 3
• Greater need for surgical intervention, ICU care, and rehabilitation 3
• Higher risk of compartment syndrome requiring fasciotomy 4

Specific Management Components

Cardiac Monitoring

• Continuous cardiac monitoring for arrhythmias
• ECG to assess for cardiac injury patterns
• Consider troponin levels for myocardial injury assessment 4

Burn Management

• Cool thermal burns with cold tap water (15-25°C) as soon as possible until pain relieved 1
• Do NOT apply ice directly - causes tissue ischemia
• Avoid prolonged cooling in large burns - risk of hypothermia 1
• Cover burn blisters with sterile dressing but leave blisters intact - improves healing and reduces pain 1
• Assess for compartment syndrome in extremity burns - may require urgent fasciotomy 4

Laboratory and Imaging Evaluation

• Urinalysis for myoglobinuria (rhabdomyolysis)
• Creatine kinase levels
• Basic metabolic panel (renal function, electrolytes)
• Consider imaging for associated traumatic injuries from falls or blast events 4

Multisystem Assessment

Monitor for:

• Neurological: altered mental status, seizures, peripheral neuropathy 4
• Renal: acute kidney injury from rhabdomyolysis
• Musculoskeletal: compartment syndrome, fractures from falls
• Ocular: cataracts (may be delayed), corneal injury 4
• Auditory: tympanic membrane rupture 4

Surgical Considerations

• Electrical burns often require grafting despite small external appearance 6
• 24% of electrical burns in one pediatric series required skin grafting 6
• 12% required rehabilitation and 20% needed compression garments for hypertrophic scars 6
• Some patients require late reconstructive surgeries for contractures and deformities 6

Critical Pitfalls to Avoid

1. Never assume minimal external injury means minimal internal damage - electrical current causes deep tissue injury along its pathway 1, 4
2. Do not discharge children with "minor" electrical injuries without full evaluation - complications can be occult or delayed 1, 4
3. Do not forget to assess for non-accidental trauma - providers should be alert to signs of potential abuse in all injured children 7
4. Do not underestimate fluid resuscitation needs - internal muscle damage may be extensive despite limited external burns 4

Disposition and Follow-up

Transfer to specialized pediatric burn center for:

• High-voltage injuries
• Significant burns requiring surgical management
• Evidence of systemic complications (arrhythmias, rhabdomyolysis, compartment syndrome)
• Providers at non-specialized centers should be able to evaluate, stabilize, and transfer acutely injured children 7

Psychological support: Evaluate and refer injured children and families for stress reactions related to injury 7
