Infants with hyponatremia can present with neurologic symptoms such as vomiting, weakness, and seizures. Common causes of hyponatremia in the infant population are excess ingestion or administration of hypotonic fluids and excessive gastrointestinal salt loss.
How do you fix hyponatremia in newborns?
Treatment of neonatal hyponatremia is with 5% D/0.45% to 0.9% saline solution IV in volumes equal to the calculated deficit, given over as many days as it takes to correct the sodium concentration by no more than 10 to 12 mEq/L/day (10 to 12 mmol/L/day) to avoid rapid fluid shifts in the brain.
Is Low sodium common in newborns?
Preterm infants are prone to hyponatremia because of a lower glomerular filtration rate, lower proximal tubular reabsorption of sodium, and an increase arginine vasopressin level when sick. Often very low birthweight infants show increased renal tubular sodium and water loss causing hyponatremia.
Why are babies at risk of hyponatremia?
Preterm neonates are at high risk for the development of hyponatremia because of (1) lower glomerular filtration rate, (2) reduced proximal tubular reabsorption of sodium, and (3) increased arginine vasopressin levels in response to illness , .
Can low sodium levels be cured?
Hyponatremia treatment is aimed at resolving the underlying condition. Depending on the cause of hyponatremia, you may simply need to cut back on how much you drink. In other cases of hyponatremia, you may need intravenous electrolyte solutions and medications.
What is the fastest way to correct sodium?
A true neurologic emergency, symptomatic acute hyponatremia can be corrected with sequential boluses of 100-300 mL of 3% saline to rapidly increase the sodium level by a goal of 4 to 6 mEq/L, a change experts say will forestall osmotic shifts and prevent the most dangerous immediate neurologic effects of a low serum …
How do pediatrics correct hyponatremia?
In patients with normovolemic hyponatremia, restriction of fluids to two-thirds (or less) of the volume needed for maintenance is the mainstay of treatment. Diuretics can be administered with fluid restriction to remove excessive free water. Once again, the change in Na levels should not exceed 8 mEq/L/d.
Can low sodium cause seizures in babies?
For infants less than six months of age with a normal exam, hyponatremia is the leading cause of new onset non-febrile seizure. Most commonly, this is secondary to water intoxication from inappropriate feeding practices.
What is the normal sodium level for infants?
The normal range for blood sodium levels is 135 to 145 milliequivalents per liter (mEq/L). Normal value ranges may vary slightly among different laboratories.
How do you correct hyponatremia?
Formula for Sodium Correction
- Fluid rate (mL / hour) = [(1000) * (rate of sodium correction in mmol / L / hr)] / (change in serum sodium)
- Change in serum sodium = (preferred fluid selected sodium concentration – serum sodium concentration) / (total body water + 1)
What causes low sodium levels in child?
Hyponatremia can be caused by heart, kidney, or liver problems, diarrhea, sweating, vomiting, dehydration, or certain drugs and medications. Since sodium is lost in sweat, hyponatremia also can be caused by drinking too much water during exercise, especially extended, intense exercise, such as a marathon or triathlon.
What causes hyponatremia kids?
The main cause of pediatric hyponatremia is an abundance of free water. This may occur in hypovolemic children with low ECF volume, normovolemic patients with inappropriately increased ADH secretion, and also in hypervolemic individuals with decreased effective circulating volume and appropriately increased ADH levels.
Why are babies and small children at greater risk for hyponatremia?
Because of their higher brain/intracranial volume ratio, children are at increased risk for these sequelae compared with adults.
How long does it take to recover from hyponatremia?
Generally, low sodium is asymptomatic (does not produce symptoms), when it is mild or related to your diet. It can take weeks or months for you to experience the effects of low salt in your diet—and these effects can be corrected by just one day of normal salt intake.
Who is at risk of hyponatremia?
Hyponatremia is more likely in people living with certain diseases, like kidney failure, congestive heart failure, and diseases affecting the lungs, liver or brain. It often occurs with pain after surgery. Also, people taking medications like diuretics and some antidepressants are more at risk for this condition.
What is the most common cause of hyponatremia?
Hyponatremia is decrease in serum sodium concentration < 136 mEq/L (< 136 mmol/L) caused by an excess of water relative to solute. Common causes include diuretic use, diarrhea, heart failure, liver disease, renal disease, and the syndrome of inappropriate antidiuretic hormone secretion (SIADH).
