Although various formulas predicting plasma sodium level ([Na]) are proposed for correction of hyponatremia, it seems that an anticipated [Na] frequently exceeds or falls below the measured [Na], especially in syndrome of inappropriate antidiuretic hormone secretion (SIADH). The causative factors of the fluctuation have never been investigated clearly. The aim of this study was to identify the determining factors for accurate prediction of [Na] by comparing data from previously proposed formulas and a novel osmotic compartment model (O-C model)...

Use of online formulas to treat hyponatremia is a common practice. We report here that while using the same goal of correction and type of infusate to treat a patient with hyponatremia, a large discrepancy in infusion rate is obtained from using the 2 commonly available online equations. When the therapy fluid is less concentrated saline (0.9%), Adrogue's formula poses the risk of large amount of volume being administered for only a small change in serum sodium concentration. This may be detrimental especially in patients with congestive heart failure...

BACKGROUND: Hypernatraemia is common in intensive care patients and may present an independent risk factor of mortality. Several formulae have been proposed to guide infusion therapy for correction of serum sodium. Unfortunately, these formulae have never been validated comparatively. We assessed the predictive potential of four different formulae (Adrogué-Madias, Barsoum-Levine, Kurtz-Nguyen and a simple formula based on electrolyte-free water clearance) in correction and maintenance of serum sodium in 66 hyper- and normonatraemic ICU patients...

We report a case of a young male with adrenal hypoplasia who presented following water intoxication with severe hyponatraemia and seizures. He required a period of intensive care and over the initial 24 h his serum sodium corrected at average of 0.9 mmol x l(-1) h(-1). He subsequently developed osmotic demyelination syndrome. Following supportive treatment he made a full recovery. Severe hyponatraemia carries a risk of cerebral oedema with a significant mortality, yet correcting it too rapidly can result in osmotic demyelination syndrome, again with potentially disastrous consequences...

BACKGROUND AND OBJECTIVES: Data regarding dosage-response relationships for using hypertonic saline in treatment of hyponatremia are extremely limited. Objectives of this study were to assess adherence to previously published guidelines (limiting correction to <12 mEq/L per d and <18 mEq/L per 48 h) in treating hyponatremia with hypertonic saline and to determine the predictive accuracy of the Adrogué-Madias formula. DESIGN, SETTING, PARTICIPANTS & MEASUREMENTS: A retrospective review was conducted of all 62 adult, hyponatremic patients who were treated with hypertonic saline during 5 yr at a 528-bed, acute care, teaching hospital...

BACKGROUND: Rapid correction of dysnatraemias is frequently associated with increased morbidity and mortality. Therefore, it is important to estimate the proper volume and type of infusate required to change the serum sodium concentration predictably. The aim of this study is to evaluate the utility or/and the accuracy of the Adrogue-Madias formula in managing patients with hyponatraemia and hypernatraemia. METHODS: Among the 317 patients who either on admission to our internal medicine clinic or during their hospitalization were found to have hyponatraemia or hypernatraemia, we studied 189 patients (59...

Rapid correction of the dysnatremias can result in significant patient morbidity and mortality. To avoid overly rapid correction of the dysnatremias, the sodium deficit equation, water deficit equation, and Adrogue-Madias equation are frequently utilized to predict the change in plasma sodium concentration (Delta[Na+]p) following a therapeutic maneuver. However, there are significant limitations inherent in these equations. Specifically, the sodium deficit equation assumes that total body water (TBW) remains unchanged...
