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. Hyponatremia is a commonly encountered electrolyte disorder among hospitalized patients, and it is often underrecognized and undertreated. Objectives To optimise and unify management of patients with hyponatremia 130mmol/L. The management of hypotonic hyponatraemia depends primarily on whether the onset is acute (i.e., <48 hours) or chronic (≥48 hours). This is because acute onset indicates the likelihood of cerebral oedema, which requires prompt treatment in a hospital. 2009; 76:577–589. A syndrome of renal sodium loss and hyponatremia probably resulting from inappropriate secretion of antidiuretic hormone. Seek emergency care for anyone who develops severe signs and symptoms of hyponatremia, such as nausea and vomiting, confusion, seizures, or lost consciousness. L.G. Lack of timely diagnosis and/or providing inadequate or inappropriate treatment can increase the risk of morbidity and mortality. 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. 2007; 120:653-658. Hyponatremia is the most frequently occurring electrolyte abnormality and can lead to life-threatening complications. Hyponatremia is common in critical care units. Low serum sodium levels can be dangerous and even fatal if hyponatremia is severe. 1. Crossref Medline Google Scholar; 25 Sterns RH, Hix JK. The management of patients with hyponatraemia with severe symptoms is best achieved by senior and specialist doctors working in a closely monitored environment in which there is easily available blood monitoring, and as such doctors who are uncertain of appropriate management strategies should seek help from appropriate medical or critical care teams as early as possible. Treat Neurologic Emergencies Related to Hyponatremia. Hypertonic saline for hyponatremia: risk of inadvertent overcorrection.

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. Hyponatremia: clinical diagnosis and management Am J Med. those with evidence of cerebral oedema) should be admitted to hospital as an emergency. 6th ed. 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. A serum sodium level below 135 mEq/L is considered hyponatremia. 23 Treatment is further strategized by the severity, which depends on the sodium level, time to development, and patient symptoms. Nursing Assessment. Call your doctor if you know you are at risk of hyponatremia and are experiencing nausea, headaches, cramping or weakness. 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.

Hyponatremia in marathon runners due to inappropriate arginine vasopressin secretion. Controversy continues to exist regarding both the cause and treatment of hyponatremia in this patient population. Hyponatremia (HN) is the most common electrolyte disorder, and is documented in 15-30% of hospitalized patients. Hyponatremia is frequently associated with hypovolemia or fluid overloa … Management is determined by presence of seizures/ altered conscious state and fluid status (see flow chart below). Hyponatremia is the most common, clinically-significant electrolyte abnormality seen in patients with aneurysmal subarachnoid hemorrhage. To reduce in-patient hospital stays attributable to hyponatremia. Close monitoring should be done for patients with fluid and electrolyte imbalances. Sodium disorders are associated with an increased risk of morbidity and mortality. HYPONATREMIA. 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.

Hyponatremia is a particularly common complication in elderly hospitalized patients, increasing in prevalence from approximately 7% in the general older population to 18% to 22% among elderly patients in chronic care facilities.21 Despite the many known causes of SIADH (Figure 1), hyponatremia is often associated with idiopathic SIADH in the elderly population. We searched MEDLINE, EMBASE, and websites of guideline organizations and professional societies to September 2014 without language restriction for … 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). the nurse should monitor for fluid I&O at least every 8 hours, or even hourly. This disorder may be present on admission to the intensive care setting or develop during hospitalization as a result of treatment or multiple comorbidities. Normal sodium levels: 135 to 145 mEq/L (<135 = hyponatremia). 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.

Hyponatremia is common in critical care units, and it can be deadly.1, 2, 3 To avoid iatrogenic injury, the intensivist must have a clear understanding of this complex electrolyte disturbance: why the serum sodium (Na) level falls and why it rises, how the brain responds to a changing serum Na concentration, what the goals of therapy should be, and how to achieve them.
