Approach to the Hypernatremic Patient

Of Water, Electrolytes, and Acid-BaseApproach to the Hypernatremic PatientFIGURE 1-29 Pathogenesis of hypernatremia. The renalconcentrating mechanism is the first line ofdefense against water depletion and hyper-osmolality. When renal concentration isimpaired, thirst becomes a very effectivemechanism for preventing further increasesin serum osmolality. The components of thenormal urine concentrating mechanism areshown in Figure 1-2. Hypernatremia resultsfrom disturbances in the renal concentratingmechanism. This occurs in interstitial renaldisease, with administration of loop andosmotic diuretics, and with protein malnu-trition, in which less urea is available togenerate the medullary interstitial tonicity.
