Which electrolyte disturbance is often seen in rhabdomyolysis?

In cases of rhabdomyolysis, the breakdown of muscle tissue releases several intracellular components into the bloodstream, one of which is potassium. As muscle cells are damaged, they release potassium, leading to an increase in the serum potassium level, resulting in hyperkalemia. This electrolyte disturbance is a significant concern as it can lead to potentially life-threatening cardiac arrhythmias.

Additionally, it is crucial to monitor other electrolytes in rhabdomyolysis, as the condition can also cause shifts in calcium and phosphate levels, but the direct and immediate concern regarding the release of potassium is the hallmark of the condition. Identifying and addressing hyperkalemia quickly can be crucial in managing patients with rhabdomyolysis, highlighting the importance of recognizing this electrolyte disturbance in clinical practice.
