Hyponatremia is the most common electrolyte disorder encountered in neurosurgical patients. The aggressive treatment of hyponatremia in this group is critical, as hyponatremia can lead to mental status changes, seizures, vasospasm, cerebral edema, and even death. When it occurs, it represents a failure of one of several homeostatic mechanisms that tightly regulate serum sodium. ⋯ Syndrome of inappropriate antidiuretic hormone is characterized by a volume-expanded state, whereas CSW is characterized by a volume-contracted state. Determining the exact cause remains a clinical imperative as the treatment for each is different. The rate at which serum sodium is corrected must be attended to, as rapid shifts in serum sodium pose potential risk of cerebral pontine myelinolysis.

Clinical course of ICU patients with severe pandemic 2009 influenza A (H1N1) pneumonia: single center experience with proning and pressure release ventilation.
A number of different modalities have been employed in addition to conventional ventilation to improve oxygenation in patients with severe 2009 pandemic influenza A (H1N1) pneumonia. Outcomes with ventilatory and rescue therapies for H1N1 influenza-related acute respiratory distress syndrome (ARDS) have been varied. A single intensive care unit (ICU) experience with management of laboratory-confirmed 2009 pandemic influenza A (H1N1) ARDS with a combination of proning and airway pressure release ventilation (APRV) is described. ⋯ Proning in combination with APRV provides improvement of hypoxemia with limitation of end-organ dysfunction and thereby facilitates recovery from severe 2009 pandemic influenza A (H1N1).
