What is the primary concern resulting from rhabdomyolysis?

The primary concern resulting from rhabdomyolysis is kidney damage. Rhabdomyolysis occurs when muscle tissue breaks down and releases its contents, including myoglobin, into the bloodstream. Myoglobin is a protein that can be harmful to the kidneys. When the kidneys filter this myoglobin, it can lead to acute kidney injury due to several factors, such as fluid overload, electrolyte imbalances, and direct toxicity from the myoglobin itself.

This kidney damage can result in conditions such as oliguria (decreased urine output), and eventually, if not managed properly, can lead to renal failure. Monitoring kidney function and ensuring adequate hydration are critical components in the management of patients who have experienced rhabdomyolysis.
