Why would you give a patient a hypertonic solution?

Why would you give a patient a hypertonic solution?

Hypertonic solutions are also useful to patients with fluid overload when they need electrolytes. This includes conditions such as Heart Failure or severe edema. 3% Saline can provide patients with needed electrolytes, all while adding minimal water.

When should hypertonic saline be used?

According to the recent European Clinical Practice Guidelines, hypertonic saline solution is recommended for the treatment of hyponatremic encephalopathy regardless of whether it is acute or chronic, whether the symptoms are moderate or severe, or if the degree of hyponatremia is moderate (125–129 mmol/l) or profound ( …

When would you use hypertonic or hypotonic solutions?

You want to give your patients a solution that has the tonicity that is opposite their problem most of the time. For example, if your patient is dehydrated their blood is hypertonic. They will need a hypotonic solution to bring their tonicity back within normal ranges.

When would you use hypertonic IV fluids?

Hypertonic sodium chloride solutions are used in the acute treatment of sodium deficiency (severe hyponatremia) and should be used only in critical situations to treat hyponatremia. They need to be infused at a very low rate to avoid the risk of overload and pulmonary edema.

When would a hypotonic solution be used?

Hypotonic solutions are used when the cell is dehydrated and fluids need to be put back intracellularly. This happens when patients develop diabetic ketoacidosis (DKA) or hyperosmolar hyperglycemia.

What are indications of hypertonic solution?

Sodium is the most abundant extracellular ion. Historically, therapy with hypertonic saline was widely used for a variety of conditions. Currently, there are 3 primary indications for its use in critical care: hyponatremia, volume resuscitation, and brain injury.

What would happen to a patient if they were given a solution that was hypertonic or hypotonic relative to their cells?

If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.

When would you give a patient a hypotonic solution?

What are hypertonic fluids used for?

Clinicians use hypertonic fluids to increase intravascular fluid volume. Hypertonic saline can be utilized in the treatment of hyponatremia. Hypertonic saline and mannitol are both indicated to reduce intracranial pressure.

Why is hypertonic saline used in Siadh?

In euvolemic hyponatremia treated with hypertonic saline, infusion of large loop diuretics promotes urinary water losses and can be used instead of vaptans. Frequent monitoring of the serum sodium concentration is imperative in this setting.

What happens hypertonic solution?

Hypertonic solutions have less water ( and more solute such as salt or sugar ) than a cell. Seawater is hypertonic. If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ).

What happens if you use a hypertonic solution instead of hypotonic?

If a hypertonic solution was put in place instead of a hypotonic solution, the cells could shrivel, killing the patient. The intricacies of the process of administering IV fluids can have a large ramifications if they one mistake is made.

When to use hypertonic or isotonic IV fluids?

Finally, hypertonic fluids are discussed. These fluids cause fluids to leave the cells and enter the intravascular space; therefore, “hypertonic solutions are used as volume expanders. Hypertonic solutions may be prescribed for patients with severe hyponatremia.

Why are hypertonic solutions used as volume expanders?

These fluids cause fluids to leave the cells and enter the intravascular space; therefore, “hypertonic solutions are used as volume expanders. Hypertonic solutions may be prescribed for patients with severe hyponatremia. Patients with cerebral edema may also benefit from an infusion of hypertonic sodium chloride” (Crawford & Harris, 2014 1).

When to use hypertonic saline in high acuity areas?

Maintain vigilance when administering hypertonic saline solutions because of their potential for causing intravascular fluid volume overload and pulmonary edema. 2 Hypertonic sodium chloride solutions should be administered only in high acuity areas with constant nursing surveillance for potential complications.
