What does hyponatremia stand for in continuing education?
Continuing Education Activity Hyponatremia is defined as a serum sodium concentration of less than 135 mEq/L but can vary to a small extent in different laboratories. Hyponatremia is a common electrolyte abnormality caused by an excess of total body water when compared to total body sodium content.
What causes hypervolemic hyponatremia in emergency room?
Causes. Hypervolemic hyponatremia occurs when sodium stores increase inappropriately. This may result from renal causes such as acute or chronic renal failure, when dysfunctional kidneys are unable to excrete the ingested sodium load. It also may occur in response to states of decreased effective intravascular volume.
When to use NaCl infusions for hyponatremia?
For patients with severe hyponatremia — even if present for weeks or months — clinicians have been advised to provide continuous 3% NaCl infusions. With such a low threshold to use powerful osmotic agents for relatively non-threatening hyponatremia, it’s unsurprising that over-correction of serum sodium is so common.
How much hypertonic saline to give for hyponatremia?
Clinicians have been advised (in expert-produced topic reviews) to give boluses of 3% hypertonic saline for patients with only moderate hyponatremia (Na = 120 to 130 mEq/L) causing only minimal symptoms.
How to tell if you have hyponatremia at Mayo Clinic?
Thirst and the color of your urine are usually the best indications of how much water you need. If you’re not thirsty and your urine is pale yellow, you are likely getting enough water. By Mayo Clinic Staff.
Which is a major solute in hyponatremia?
Hyponatremia represents an imbalance in this ratio where total body water is more than total body solutes. Total body water (TBW) has two main compartments, extracellular fluid (ECF) accounting for one-third and intracellular fluid (ICF), accounting for the remaining two-thirds. Sodium is the major solute of ECF and potassium for ICF.
What causes hyponatremia when you drink too much water?
In hyponatremia, one or more factors — ranging from an underlying medical condition to drinking too much water — cause the sodium in your body to become diluted. When this happens, your body’s water levels rise, and your cells begin to swell.
