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). **Important Legal Notice:** This application is a clinical decision support tool for healthcare professionals. **It does NOT replace clinical judgment.** The author is not responsible for decisions made based solely on this tool.
