Electrolyte disturbances are frequently encountered in critically ill oncology patients. Hyponatremia and hypernatremia as well as hypocalcemia and hypercalcemia are among the most commonly encountered electrolyte abnormalities. In the intensive care unit, management of critical electrolyte disturbances is focused on initial evaluation and immediate treatment plan to prevent severe complications. A PubMed search was performed to identify best available evidence for evaluation and management of dysnatremias, hypocalcemia, and hypercalcemia...

INTRODUCTION: Dysnatremia commonly occur in the intensive care unit (ICU)- management of patients with aneurysmal subarachnoid hemorrhage (SAH). However, detailed management strategies have not been provided even by current guidelines. The purposes of this study were to examine the association of abnormal serum sodium levels with unfavorable neurologic outcomes and to identify the target range of serum sodium in patients with SAH. METHODS: We retrospectively reviewed all patients who were consecutively hospitalized with a confirmed diagnosis of SAH between January 2009 and December 2015...

REVIEW
Craig Hutto, Mindy French
Dysnatremia is a common finding in the intensive care unit (ICU) and may be a predictor for mortality and poor clinical outcomes. Depending on the time of onset (ie, on admission vs later in the ICU stay), the incidence of dysnatremias in critically ill patients ranges from 6.9% to 15%, respectively. The symptoms of sodium derangement and their effect on brain physiology make early recognition and correction paramount in the neurologic ICU. Hyponatremia in brain injured patients can lead to life-threatening conditions such as seizures and may worsen cerebral edema and contribute to alterations in intracranial pressure...

PURPOSE: Serum sodium derangement is the most common electrolyte disturbance among patients admitted to intensive care. This study aims to validate the association between dysnatremia and serum sodium fluctuation with mortality in surgical intensive care patients. METHOD: We performed a retrospective analysis of the Medical Information Mart for Intensive Care II database. Dysnatremia was defined as a sodium concentration outside physiologic range (135-145mmol/L) and subjects were categorized by severity of dysnatremia and sodium fluctuation...

Several studies have demonstrated the impact of dysnatremias on mortality of intensive care unit (ICU) patients. The objective of this study was to assess whether dysnatremia is an independent factor to predict mortality in surgical critically ill patients admitted to ICU in postoperative phase.One thousand five hundred and ninety-nine surgical patients (58.8% males; mean age of 60.6 ± 14.4 years) admitted to the ICU in the postoperative period were retrospectively studied. The patients were classified according to their serum sodium levels (mmol/L) at admission as normonatremia (135-145), hyponatremia (<135), and hypernatremia (>145)...

The assumption that sodium accumulation in the human body is always accompanied by water retention has been challenged by data showing that sodium can be stored nonosmotically. Here we investigated the contribution of nonosmotic sodium storage to short-term sodium homeostasis after hypertonic saline infusion in healthy individuals on a low-sodium diet. During four hours after infusion, we compared the observed changes in plasma sodium concentration and urinary cation excretion with changes that were calculated with the Adrogue-Madias and Nguyen-Kurtz formula, formulations widely implemented to guide the treatment of dysnatremias...

REVIEW
Julien Guillaumin, Stephen P DiBartola
This review article discusses normal and abnormal sodium balance in small animals. The terms and concepts central to understanding normal sodium and water balance are presented as well as of the physiology of body fluid compartments and the movement of fluid between those compartments. As dysnatremia is a very common disorder across the spectrum of critically ill patients, the main focus of the article is to present several clinical examples of both acute and chronic hypernatremia and hyponatremia and their practical, clinical management...

Dysnatremias (DN) are common electrolyte disturbances in cardiac critical illness and are known risk factors for adverse outcomes in certain populations. Little information exists on DN in children with cardiac disease admitted to the cardiac intensive care unit (CICU) after undergoing cardiac surgery, either corrective or palliative. The aim was to determine the incidence and adverse outcomes associated with DN in neonates and infants undergoing cardiac surgery. Retrospective cohort and single center study performed at Children's Hospital Colorado from May 2013 to May 2014, in children under 1 year old admitted to the CICU after undergoing surgery for congenital or acquired cardiac disease...

BACKGROUND: Sodium disarrays are common in peritoneal dialysis (PD) patients, and may be associated with adverse outcomes in this population. However, few studies of limited sample size have examined the association of serum sodium with mortality in PD patients, with inconsistent results. We hypothesized that both hypo- and hypernatremia are associated with higher death risk in a nationally representative cohort of US PD patients. METHODS: We sought to examine the association of serum sodium over time and mortality among 4687 adult incident PD patients from a large US dialysis organization who underwent one or more serum sodium measurements within the first 3 months of dialysis over January 2007 to December 2011...

Background: Frailty represents an age-related state of increased risk of adverse health outcomes, reflecting some combination of increased damage and compromised repair processes. Our objectives were to establish whether frailty is associated with dysnatremia (a deviation of serum sodium from normal values), to determine whether frailty explains the previously established association between age and dysnatremia and to assay the impact of each on mortality. Methods: The relationship between age, frailty, and dysnatremia was investigated across the adult life course in 8,911 respondents from the 2003-2004 and 2005-2006 cross-sectional National Health and Nutrition Examination Survey, on whom both laboratory and mortality data were available...

Because changes in the plasma water sodium concentration ([Na(+)]pw) are clinically due to changes in the mass balance of Na(+), K(+), and H2O, the analysis and treatment of the dysnatremias are dependent on the validity of the Edelman equation in defining the quantitative interrelationship between the [Na(+)]pw and the total exchangeable sodium (Nae), total exchangeable potassium (Ke), and total body water (TBW) (Edelman IS, Leibman J, O'Meara MP, Birkenfeld LW.

BACKGROUND: Hyponatremia and hypernatremia are associated with death in the general population and those with chronic kidney disease (CKD). We studied the associations between dysnatremias, all-cause mortality and causes of death in a large cohort of Stage 3 and 4 CKD patients. METHODS: We included 45 333 patients with Stage 3 and 4 CKDs followed in a large healthcare system. Associations between hyponatremia (<136 mmol/L) and hypernatremia (>145), and all-cause mortality and causes of death (cardiovascular, malignancy related and non-cardiovascular/non-malignancy related) were studied using Cox proportional hazards and competing risk models...
