Kidney Int. PATIENT Any patient who has serum blood sodium (Na) result <135mmol/L (<130 mmol/L in pregnancy) Mild−moderate hyponatremia is usually defined as serum Na 121-135 mmol/L Severe hyponatremia is defined as serum Na ≤120mmol/L. the nurse should monitor for fluid I&O at least every 8 hours, or even hourly. However, 30-40% of ICU patients have HN, and these patients have high mortality rates. 1. The expectations of nursing management are focused on restoring homeostasis and preventing additional complications. Introduction. Crossref Medline Google Scholar; 25 Sterns RH, Hix JK. In this regard, Stelfox et al. Hyponatremia is defined as a serum sodium level of less than 135 mEq/L and is considered severe when the serum level is below 125 mEq/L. Low serum sodium levels can be dangerous and even fatal if hyponatremia is severe. 6th ed. Hyponatremia in marathon runners due to inappropriate arginine vasopressin secretion. 2008; 14:627–634. Hyponatremia is frequently associated with hypovolemia or fluid overloa … 23 Treatment is further strategized by the severity, which depends on the sodium level, time to development, and patient symptoms. Hyponatremia is the most common, clinically-significant electrolyte abnormality seen in patients with aneurysmal subarachnoid hemorrhage. This condition can be due to low levels of sodium or to excess water in relation to the amount of sodium, ... Urden L, Stacy K, Lough M. Thelan's Critical Care Nursing. Siegel AJ, Verbalis JG, Clement S, et al. A syndrome of renal sodium loss and hyponatremia probably resulting from inappropriate secretion of antidiuretic hormone. Nursing Management. In addition to correcting the serum sodium, the management of hyponatraemia must always include treatment of the underlying cause. Daily weight. Nursing Care Plans. Management is determined by presence of seizures/ altered conscious state and fluid status (see flow chart below). L.G. She has had four pulmonary bacterial infections during the last 7 years and was found to have radiologic evidence of bronchiectasis. CMAJ. Avoidance of neurologic injury requires a clear understanding of why the serum sodium (Na) concentration falls and why it rises, how the brain responds to a changing serum Na concentration, and what the goals of therapy should be. American Journal of Medicine 1957 23 529–542 and Janicic N & Verbalis JG. Clin Nephrol 1996; 46:149. This chapter outlines the treatment of low serum sodium levels in patients in the neonatal intensive care unit (NICU), particularly those dependent on parenteral fluids. 1,2 Likewise, hyponatremia is a mortality predictor in critical patients. Hypertonic saline for hyponatremia: risk of inadvertent overcorrection. Plasma osmolality plays a critical role in the pathophysiology and treatment of sodium disorders. We aimed to explore the scope, content, and consistency of these documents. Epidemiology The reported incidence of a serum sodium below 130 for very low birth weight infants in the NICU varies in the literature from about one-quarter to one-third. Hypervolemic hyponatremia, the type of most concern in critical care, is the result of excess fluid causing sodium dilution 10 ; about 25% of patients with hyponatremia have the hypervolemic type. The nurse meets these goals by administering intravenous solutions and other therapies that are appropriate to the underlying cause and the patient’s status, performing frequent assessments, and monitoring cardiac function by interpreting the EKG readings. Administer 3% hypertonic saline 100-150cc IV over 5-10min The management of hypotonic hyponatraemia depends primarily on whether the onset is acute (i.e., <48 hours) or chronic (≥48 hours). The treatment of hyponatremia involves the removal of free water, treatment of underlying causes, and use of saline infusion. Hyponatraemia is the most frequently observed electrolyte abnormality.1 Mild hyponatraemia is associated with cognitive deficits and falls, but in hospitalised patients it is associated with increased mortality.2 In primary care, patients are often found to have hyponatraemia during chronic disease monitoring. 2 Hypervolemic hyponatremia can be differentiated from euvolemic hyponatremia on the basis of physical signs of fluid overload, such as jugular venous distention, pulmonary edema, and/or pitting edema. Hypernatremia Disease: Hypernatremia disease is an elevated sodium level in the blood. Soupart A, Decaux G. Therapeutic recommendations for management of severe hyponatremia: current concepts on pathogenesis and prevention of neurologic complications. Hyponatremia: clinical diagnosis and management Am J Med. Multiple organizations have published guidance documents to assist clinicians in managing hyponatremia. The key to understanding hyponatremia is relating it to volume status. Hyponatremia is a common electrolyte disorder.

Sodium disorders are associated with an increased risk of morbidity and mortality. Nurses may use effective teaching and communication skills to help prevent and treat various fluid and electrolyte disturbances. The AVP-receptor antagonists, a new class of agents, correct hyponatremia by directly blocking the binding of AVP with its receptors. The hyponatremic patient: a systematic approach to laboratory diagnosis. 24 Schrier RW, Bansal S. Diagnosis and management of hyponatremia in acute illness. She was known to have had hyponatremia for several years, with serum sodium levels in the range of 121–127 mEq/L. Joint Trust Guideline for Inpatient Management of Hyponatremia 2. Management of other patients … This could be withdrawing the probable causative drug, treating postoperative pain, treating hormonal abnormalities and treating identifiable causes of the syndrome of inappropriate antidiuretic hormone secretion. Many medical illnesses, such as congestive heart failure, liver failure, renal failure, or pneumonia, may be associated with hyponatremia. This is because acute onset indicates the likelihood of cerebral oedema, which requires prompt treatment in a hospital. 2002 April 16; 166(8): 1056 -1062. Seek emergency care for anyone who develops severe signs and symptoms of hyponatremia, such as nausea and vomiting, confusion, seizures, or lost consciousness. Nursing care plan and goals for fluid and electrolyte imbalances include: maintaining fluid volume at a functional level, patient exhibits normal laboratory values, demonstrates appropriate changes in lifestyle and behaviors including eating patterns and food quantity/quality, re-establishing and maintaining normal pattern and GI functioning. The syndrome of inappropriate secretion of antidiuretic hormone (SIADH) is one of the causes of hyponatremia. Crossref Google Scholar To reduce risk of osmotic demyelination from rapid correction of hyponatremia.

Hyponatremia is a commonly encountered electrolyte disorder among hospitalized patients, and it is often underrecognized and undertreated. Evaluation and management of hypo-osmolality in hospitalized patients. Hyponatremia is defined as a serum sodium concentration of 136 mmol/l, and is the most common electrolyte disorder in hospitalized patients (affecting 15–20% of all individuals requiring hospital admission). Mohmand HK, Issa D, Ahmad Z, et al. To reduce in-patient hospital stays attributable to hyponatremia. management of patients with hyponatremia 2.
