If the sodium level is <120 mEq/L, the person can be treated with hypertonic saline as extremely low levels are associated with severe neurological symptoms. [14] In non-emergent situations, it is important to correct the sodium slowly to minimize risk of osmotic demyelination syndrome.
Hyponatremia or hyponatraemia is a low concentration of sodium in the blood. [4] It is generally defined as a sodium concentration of less than 135 mmol/L (135 mEq/L), with severe hyponatremia being below 120 mEq/L. [3] [8] Symptoms can be absent, mild or severe.
Saline solution for irrigation. Normal saline (NSS, NS or N/S) is the commonly used phrase for a solution of 0.90% w/v of NaCl, 308 mOsm/L or 9.0 g per liter. Less commonly, this solution is referred to as physiological saline or isotonic saline (because it is approximately isotonic to blood serum, which makes it a physiologically normal solution).
Urinary loss (urine sodium > 20) Diuretic drugs (especially thiazides) Addison's disease; Cerebral salt-wasting syndrome; Other salt-wasting kidney diseases; Treat underlying cause and give IV isotonic saline. It is important to note that sudden restoration of blood volume to normal will turn off the stimulus for continued ADH secretion.
The presence of cerebral edema, or other moderate to severe symptoms, may necessitate intravenous hypertonic saline administration with close monitoring of the serum sodium levels to avoid overcorrection. [2] SIADH was originally described in 1957 in two people with small-cell carcinoma of the lung. [3]
To maintain electrical neutrality, the solution has a lower level of sodium than that found in blood plasma or normal saline. [4] Generally, the source of the constituent ions is a mixture of sodium chloride (NaCl), sodium lactate (CH 3 CH(OH)CO 2 Na), calcium chloride (CaCl 2), and potassium chloride (KCl), dissolved into distilled water.
If the patient presents with acute hyponatraemia (low sodium levels due to overhydration) caused by psychogenic polydipsia, treatment usually involves administration of intravenous hypertonic (3%) saline until the serum sodium levels stabilise to within a normal range, even if the patient becomes asymptomatic. [30]
A bolus intravenous dose of 10 or 20 mg of furosemide can be administered and then followed by intravenous bolus of 2 or 3% hypertonic saline to increase the serum sodium level. [ 12 ] Pulmonary edema - Slow intravenous bolus dose of 40 to 80 mg furosemide at 4 mg per minute is indicated for patients with fluid overload and pulmonary edema.
