Which of the following treatments is often recommended for managing conditions associated with high potassium levels during anesthesia?

The management of high potassium levels, especially in the context of anesthesia, emphasizes the careful selection of muscle relaxants due to their effects on the neuromuscular system. Atracurium is often the preferred choice because it is metabolized through a process called ester hydrolysis and non-specific plasma esterases. This metabolism does not rely on renal function, making it a safer choice for patients who may have renal impairment or elevated potassium levels.

In cases of hyperkalemia, there’s a concern for the use of certain neuromuscular blockers, particularly succinylcholine, which can lead to further potassium release from muscle cells, worsening hyperkalemia. Non-depolarizing muscle relaxants like atracurium are thus preferable as they have a more stable profile in managing neuromuscular blockade in high-potassium scenarios.

Additionally, other agents, such as pancuronium, can prolong neuromuscular block and may have cardiac implications in patients with electrolyte imbalances. Dantrolene is primarily used to treat malignant hyperthermia and is not a standard treatment for hyperkalemia. Therefore, atracurium emerges as the most suitable option for patients experiencing high potassium levels during anesthesia.
