Are there instances when you use a 3% sodium chloride infusion for patients with chronic hyponatremia secondary to SIADH but who are asymptomatic or have only mild symptoms?

When do you use a 3% sodium chloride infusion for patients with chronic hyponatremia due to SIADH who are asymptomatic or have only mild symptoms?

• To rapidly increase serum sodium for clinical reasons, such as preparing a patient for surgery
• To address potential subtle impairments, as chronic hyponatremia can cause cognitive deficits, gait instability, and increased risk of bone loss even in
• When urinary electrolyte-free water clearance is very low or negative, and free water restriction is ineffective in preventing further serum sodium decrease
• I do not use 3% NaCl infusion in asymptomatic or mildly symptomatic chronic SIADH patients
• Other
