What type of hyperthermia may lead to acute renal failure without immediate treatment?

The type of hyperthermia that may lead to acute renal failure without immediate treatment is malignant hyperthermia. This condition is a rare, life-threatening genetic disorder that can be triggered by certain anesthetic agents and is characterized by a rapid increase in body temperature and severe muscle contractions. If not treated promptly, the intense muscle metabolism can cause a dramatic increase in metabolic rate, leading to a release of large amounts of potassium from muscle cells into the bloodstream. This can result in hyperkalemia, which can significantly affect kidney function and lead to acute renal failure.

Timely intervention is crucial in malignant hyperthermia to manage symptoms and prevent severe complications such as renal failure. If treatment is delayed, the metabolic disturbances can escalate rapidly, resulting in systemic complications, including damage to vital organs like the kidneys. The other types of hyperthermia may also be serious, but they do not typically have this specific direct link to acute renal failure if not addressed immediately.
