Osmotic demyelination as a complication of hyponatremia correction: a systematic review.

The development of osmotic demyelination was predominant in women under 50 years of age, with severe hyponatremia and rapid correction. In 10.4% of cases, there was demyelination even with correction <10 mEq/L/day. These data reinforce the need for conservative targets for high-risk patients, such as 4-6 mEq/L/day, not exceeding the limit of 8 mEq/L/day.
