Episode notes
Isotonic Fluid Challenge and SIADH
- An isotonic fluid challenge can be diagnostic for SIADH.
- Patients with SIADH paradoxically retain water and excrete sodium when given isotonic fluids, lowering their sodium further.
The Edematous, Volume-Depleted Patient
- Josh Farkas recounts a case of a seemingly edematous patient who was actually volume depleted.
- History, like the patient reporting nausea and not eating, is crucial, often outweighing physical exam findings like edema.
Hyponatremia Risk Stratification
- Assess hyponatremia patients for two risks: worsening hyponatremia/herniation and overcorrection.
- Acute hyponatremia, symptomatic patients, and those with brain substrates are at higher risk for seizures/herniation, while chronic severe hyponatremia carries an overcorrection risk.
