A2 Lee, Kiwon SR Print(0) ID 1101645531 T1 Disorders of Water Homeostasis: Hypo- and Hypernatremia T2 The NeuroICU Book YR 2012 FD 2012 PB McGraw-Hill Education PP New York, NY SN 9780071636353 LK neurology.mhmedical.com/content.aspx?aid=1101645531 RD 2024/04/23 AB Critically ill patients are prone to a wide variety of fluid, electrolyte, and acid-base disorders. Two of those disorders are of particular relevance to patients with critical neurologic illness: hyponatremia and hypernatremia. These are by far the most common electrolyte abnormalities in patients with central nervous system disease and have the most pressing diagnostic and therapeutic implications. This chapter therefore will focus exclusively on these disorders. Interested readers will find a recent, more comprehensive discussion of fluid, electrolyte, and acid-base abnormalities in critically ill patients elsewhere.1
