What are likely immediate life-threatening effects of electrical or lightning burns?

• A. Renal failure
• B. Splenic rupture
• C. Cardiac or Pulmonary arrest/dysrhythmias
• D. Severe GI bleeding

Answer: (C)

The immediate danger from electrical or lightning burns is disruption of the heart’s rhythm and the ability to breathe. When current passes through the chest, it can depolarize the heart and trigger dangerous arrhythmias such as ventricular fibrillation, or cause sudden cessation of respiration. Lightning strikes can cause a rapid, massive current that leads to cardiac arrest and apnea right away, even if the external burns aren’t severe. These events happen in the first moments and require rapid resuscitation with airway management, ventilation, and defibrillation if indicated. Later complications like renal failure, splenic rupture, or severe GI bleeding may occur, but they’re not typically immediate life-threatening events. They tend to emerge after the initial injury due to muscle breakdown, bleeding, or organ damage rather than the immediate electrical disruption of heart and lungs.
