Disnatremias Support

Dysnatremias Support is an essential application for healthcare professionals, designed by Dr. Carlos Xavier Rivera Rueda, a Critical Care Medicine Specialist. It offers comprehensive support for the diagnosis and management of sodium imbalances, based on standard clinical guidelines (European/American).

Key Features:

Hyponatremia (< 135 mEq/L):
* Etiological Diagnostic Algorithm: A step-by-step guide to determining the cause of hyponatremia, evaluating:

* Plasma Tonicity: Calculation of effective osmolality (Na, Glucose, BUN/Urea).

* Dilution Capacity: Analysis of urine osmolality (Uosm).

* Urinary Volume and Electrolytes: Interpretation of urinary sodium (Ua) and clinical volume status (hypo/eu/hypervolemic).

* Emergency Management: 3% NaCl bolus protocols for severe symptomatic hyponatremia (seizures, coma, herniation), with options based on:

* European Guidelines (150 mL over 20 min).

* American Guidelines (100 mL over 10 min).

* Pediatric/Weight Protocol (2 mL/kg).

* Immediate goal: increase Na+ by 4-6 mEq/L in 1-2 hours to reverse the emergency.

* Differential between SIADH and CSW: Specific tool to distinguish between these conditions.

HYPERNATREMIA (> 145 mEq/L):

* Free Water Deficit Calculation: Precise tool to estimate the amount of water needed.

* * Correction Plan: Guidance on the correction rate to avoid cerebral edema, emphasizing the risk of osmotic demyelination and cerebral adaptation with idiogenic osmolytes. Maximum recommended rate: 0.5 mEq/L per hour.

LIBRARY & EDUCATIONAL FORMULAS:
* Correction Targets: Details on Na+ correction limits for acute and chronic hyponatremia, and associated risks such as Osmotic Demyelination Syndrome (ODS).

* Pharmaceutical Techniques: Calculation of mixtures (e.g., 3% NaCl) for preparing hypertonic solutions.

* Key Formulas: Quick access to formulas such as:

* Effective plasma osmolality.

* Free water deficit.

* Na+ exchange with infusion (Adrogué).

* FENa (Fractional Excretion of Sodium).

* FE Urea (Fractional Excretion of Urea).
