[Dysnatremia].

Area of Science:

• Anesthesiology and Critical Care Medicine
• Nephrology and Endocrinology
• Neurology

Context:

• Serum sodium concentration abnormalities (dysnatremia) are common in clinical practice, particularly during anesthesia.
• These imbalances are complex and often inadequately managed, leading to feared neurological sequelae like cerebral edema, hemorrhage, and coma.
• Assessing volume status and extracellular volume is challenging in acute settings, complicating routine dysnatremia classification based on tonicity.

Purpose:

• To provide a structured overview of dysnatremias, including diagnosis and treatment recommendations.
• To address the complexities of managing both hyponatremia and hypernatremia.
• To offer a practical algorithm for clinical routine to guide anesthesiologists in managing serum sodium disturbances.

Summary:

• The abstract discusses the challenges in managing serum sodium imbalances (dysnatremia), highlighting risks like cerebral edema and central pontine myelinolysis.
• Severe hyponatremia treatment involves hypertonic saline, with careful monitoring to prevent rapid sodium correction.
• Hypernatremia management requires clarifying the cause, compensating water deficiency, and employing specific volume therapy and drug support, all while ensuring slow, controlled correction to avoid neurological damage.

Impact:

• Development of a clinical algorithm to standardize the diagnosis and treatment of dysnatremia.
• Improved patient outcomes by mitigating the risk of severe neurological complications associated with serum sodium imbalances.
• Enhanced clinical decision-making for anesthesiologists managing acute and chronic dysnatremia in diverse patient populations.
