Pseudohyponatremia hyperglycemia correction
WebStep 1: differentiate true hyponatremia from pseudohyponatremia. A normal or elevated effective serum osmolality (280 mOsm/kg or greater) suggests pseudohyponatremia. Hypertonic states, like hyperglycemia or mannitol use, can cause hyponatremia by … WebJun 19, 2024 · “Pseudohyponatremia” can also be seen with hypercholesterolemia, hypertriglyceridemia, and abnormalities in plasma proteins as found in multiple myeloma.

Hyponatremia without hypotonicity can be found in patients with hyperglycemia and in patients who have accumulated exogenous effective osmoles like … WebThis sodium correction in hyperglycemia calculator requires two important patient data in order to work: the sodium measured value in mEq/L and glucose value that you can input in either mg/dL or mmol/L (or any unit form the list provided). The formula used is the following: Na = Sodium measured value + 0.016 * (Glucose value - 100)
WebPurpose: There are no controlled experimental data that assess the accuracy of the commonly used correction factor of a 1.6 meq/L decrease in serum sodium concentration for every 100 mg/dL increase in plasma glucose concentration. The purpose of this study was to evaluate experimentally the hyponatremic response to acute hyperglycemia.
