Case 50 Electrical Injuries
50.1 Description
Evidence of full-thickness burn to the right shoulder, suggesting this as a possible entry site
Exit site of electrical current is unclear
50.2 Work-Up
50.2.1 History
Age, gender, handedness, and occupation
Past medical, surgical, and social history
Source of electricity: Power line, power outlet, lightning, electrical arc, etc.
Intensity of electricity: High voltage (≥1,000 V) or low voltage (<1,000 V)
Points of contact with electricity: Grasp of power source, fall onto power source, or nearby flash from power source
Context of injury: Concurrent with fall or other trauma
Type of electrical current: Alternating current (AC) or direct current (DC)
Duration of contact with power source
50.2.2 Physical Examination
Advanced Trauma Life Support (ATLS) Protocol: Primary survey
ABCs: Assess if airway is maintained and assess for inhalation injury
Expose patient for evaluation; remove all potentially constricting clothing and jewelry
Secondary survey: Complete ATLS secondary survey
% Total Body Surface Area burn: Rule of Nines (see Fig. 49.1)
Indications for transfer to a burn center (Table 50.1)
Neurological examination: Establish baseline neurological examination, assess sensation in all limbs, assess mental status, and evaluate cranial nerves
Vascular examination: Assess perfusion of limbs
Otoscopic and ophthalmologic examination assessing extent of injury
Orthopedic examination: Assess for any concurrent orthopedic trauma
Compartment syndrome assessment
High index of suspicion for both upper and lower extremities
Disproportionately severe pain to active and passive motion
Assess tenderness and firmness of extremity compartments
Measure compartment pressures: Can use needle pressure gauge (STIC pressure monitor; Stryker, Kalamazoo, MI)
Pressure >30 mmHg is an indication for compartment release
Pain, pallor, paresthesias, paralysis, and pulselessness are all indications for release and are late findings
