Nursing Management. 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. 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. 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. Hyponatremia is frequently associated with hypovolemia or fluid overloa … Plasma osmolality plays a critical role in the pathophysiology and treatment of sodium disorders. Sodium disorders are associated with an increased risk of morbidity and mortality. 2007; 120:653-658. Hyponatremia is common in critical care units. 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. those with evidence of cerebral oedema) should be admitted to hospital as an emergency. Nursing Care Plans. The syndrome of inappropriate secretion of antidiuretic hormone (SIADH) is one of the causes of hyponatremia. To reduce risk of osmotic demyelination from rapid correction of hyponatremia. I&O. American Journal of Medicine 1957 23 529–542 and Janicic N & Verbalis JG. Seek emergency care for anyone who develops severe signs and symptoms of hyponatremia, such as nausea and vomiting, confusion, seizures, or lost consciousness.

Treat Neurologic Emergencies Related to Hyponatremia. 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. management of patients with hyponatremia 2. Overcorrection of hyponatremia is a medical emergency. 6th ed. CMAJ. 23 Treatment is further strategized by the severity, which depends on the sodium level, time to development, and patient symptoms. To reduce in-patient hospital stays attributable to hyponatremia. Normal sodium levels: 135 to 145 mEq/L (<135 = hyponatremia). Hypertonic saline for hyponatremia: risk of inadvertent overcorrection. Hyponatremia is a commonly encountered electrolyte disorder among hospitalized patients, and it is often underrecognized and undertreated. This disorder may be present on admission to the intensive care setting or develop during hospitalization as a result of treatment or multiple comorbidities. The treatment of hyponatremia involves the removal of free water, treatment of underlying causes, and use of saline infusion. Clin Nephrol 1996; 46:149. 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. Soupart A, Decaux G. Therapeutic recommendations for management of severe hyponatremia: current concepts on pathogenesis and prevention of neurologic complications. Hyponatremia (HN) is the most common electrolyte disorder, and is documented in 15-30% of hospitalized patients. Call your doctor if you know you are at risk of hyponatremia and are experiencing nausea, headaches, cramping or weakness. 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). Nurses may use effective teaching and communication skills to help prevent and treat various fluid and electrolyte disturbances. Kidney Int. We searched MEDLINE, EMBASE, and websites of guideline organizations and professional societies to September 2014 without language restriction for … In addition to correcting the serum sodium, the management of hyponatraemia must always include treatment of the underlying cause. Hyponatremia is the most common, clinically-significant electrolyte abnormality seen in patients with aneurysmal subarachnoid hemorrhage. 24 Schrier RW, Bansal S. Diagnosis and management of hyponatremia in acute illness. 2008; 14:627–634. A serum sodium level below 135 mEq/L is considered hyponatremia. Mohmand HK, Issa D, Ahmad Z, et al. Diagnosis and Management. 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. Multiple organizations have published guidance documents to assist clinicians in managing hyponatremia. Step-Wise Approach to Emergency Management of Hyponatremia. However, 30-40% of ICU patients have HN, and these patients have high mortality rates. Serum sodium concentration plays a major role in the body's volume status. the nurse should monitor for fluid I&O at least every 8 hours, or even hourly. Role of sodium in the body: An important electrolyte that helps regulate water inside and outside of the cell.Remember that water and sodium loves each other and where ever sodium goes so does water.Sodium also play a role in muscle, nerves, and organ function. Joint Trust Guideline for Inpatient Management of Hyponatremia 2. Milionis HJ, Liamis GL, Elisaf MS. This is because acute onset indicates the likelihood of cerebral oedema, which requires prompt treatment in a hospital. 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. Management of hyponatremia ranges from stopping inappropriate water intake to using sophisticated V2-antagonist drugs to abolish the effects of vasopressin on the cortical collecting duct. The AVP-receptor antagonists, a new class of agents, correct hyponatremia by directly blocking the binding of AVP with its receptors. She was known to have had hyponatremia for several years, with serum sodium levels in the range of 121–127 mEq/L. The target rate of serum sodium correction is 6-8mmol/L in 24 hours (unless seizing- see flow chart below). Close monitoring should be done for patients with fluid and electrolyte imbalances. Hypernatremia Disease: Hypernatremia disease is an elevated sodium level in the blood. Adapted from Schwartz WB, Bennett W, Curelop S & Bartter FC. Evaluation and management of hypo-osmolality in hospitalized patients. In clinical trials, conivaptan, lixivaptan, tolvaptan, and satavaptan have increased serum osmolality and normalized the serum [Na(+)] in hyponatremia associated with … The college loves this topic, because inevitably hypertonic saline comes up as a topic of discussion. 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. Hyponatremia is the most frequently occurring electrolyte abnormality and can lead to life-threatening complications. 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. The expectations of nursing management are focused on restoring homeostasis and preventing additional complications. Administer 3% hypertonic saline 100-150cc IV over 5-10min 1,2 Likewise, hyponatremia is a mortality predictor in critical patients. Management of other patients … Nursing Assessment. Management of severe hyponatraemia (serum sodium <120mmol/L) Definition • Acute hyponatremia is defined as hyponatremia (serum Na < 135mmol/L) presenting within 48 hours • Symptomatic hyponatremia is defined as any biochemical degree of hyponatremia presenting with moderately to severe neurological symptoms 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. Management is determined by presence of seizures/ altered conscious state and fluid status (see flow chart below). Lack of timely diagnosis and/or providing inadequate or inappropriate treatment can increase the risk of morbidity and mortality. In this regard, Stelfox et al.

Crossref Google Scholar is a 73-year-old woman referred for management of chronic hyponatremia. Many medical illnesses, such as congestive heart failure, liver failure, renal failure, or pneumonia, may be associated with hyponatremia. 2009; 76:577–589. 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 management of hypotonic hyponatraemia depends primarily on whether the onset is acute (i.e., <48 hours) or chronic (≥48 hours). The hyponatremic patient: a systematic approach to laboratory diagnosis. The key to understanding hyponatremia is relating it to volume status. Hyponatremia: clinical diagnosis and management Am J Med. Low serum sodium levels can be dangerous and even fatal if hyponatremia is severe. Am J Med 2007; 120:461.e11. Controversy continues to exist regarding both the cause and treatment of hyponatremia in this patient population. Siegel AJ, Verbalis JG, Clement S, et al. Hyponatremia and hypernatremia are classified based on volume status (hypovolemia, euvolemia, and hypervolemia). L.G. Crossref Medline Google Scholar; 25 Sterns RH, Hix JK. We aimed to explore the scope, content, and consistency of these documents. 1. Hyponatremia is a common electrolyte disorder. In the event of a seizure, coma or suspected cerebral herniation as a result of hyponatremia, IV 3% hypertonic saline should be administered as soon as possible according to the following guide:.
