Electrolyte disorders / Nephrolithiasis

Abstract

stable in 5% of cases, worst in 43% of cases. Conclusions: Our study confirms that hypernatremia is a situation known in less than 1% of patients admitted to the emergency department. It mostly happens with old patients, with cognitive disorders, and generally it is associated with extracellular dehydration. Most of the times, the admission’s reason to the emergency is confused with the cause of hypernatremia. The mortality of hypernatremic patients is important because of underlying comorbidities and the reason for admission to the emergency. After one day of hospitalization, 43% of patients have serum sodium higher than at the entrance. The factors which increase the natremia are numerous: inadequate choice for the rehydration fluid, no calculation of water deficit, less prescription by prescriber (rate). Hypernatremia is a situation related with a significant mortality. The emergency management of hypernatremia has to be improved. Several factors lead to the aggravation of the hypernatremia during the first 24 hours for some patients.
