Which conditions need to be monitored in a person who sustains electrical injury?

• A. Rhabdomyolysis
• B. Compartment syndrome
• C. Renal failure
• D. All of the above

Answer: (D)

Electrical injuries can injure muscle, nerve, and heart, and problems often unfold over hours to days. The most important idea is that such injuries can trigger rhabdomyolysis, swelling inside muscle compartments, and kidney injury, so vigilant monitoring for all these issues is needed. Rhabdomyolysis occurs when damaged muscle cells release myoglobin and potassium into the bloodstream. This can lead to acute kidney injury as myoglobin clogs renal tubules and as electrolyte disturbances, especially high potassium, raise the risk of life-threatening arrhythmias. Because of this, clinicians watch for rising CK and myoglobin levels, track kidney function (creatinine, BUN), monitor electrolytes, and keep a close eye on urine output and urine color. Aggressive IV fluids are usually used to preserve kidney perfusion and urine flow, and electrolyte abnormalities are corrected promptly. Compartment syndrome is another threat after electrical injury, especially with deep tissue damage. Swelling within a muscle compartment can raise pressure, cut off blood flow, and threaten limb viability. This requires serial neurovascular exams and, if suspicion remains or pressures are high, direct measurement of compartment pressures and timely intervention to relieve pressure. Renal failure and electrolyte disturbances are closely linked to the systemic effects of the injury; even when initial exams look ok, delayed kidney problems can develop, so ongoing assessment of renal function and urine output is essential. In addition, continuous cardiac monitoring is prudent because electrical currents can affect the heart’s conduction system, and electrolyte swings from muscle injury can precipitate arrhythmias. Since each of these issues can arise after an electrical injury, monitoring for all of them is the appropriate approach.
