What are crystalloids?

IV fluids made of small molecules that pass easily through cell membranes. They can be hypotonic, isotonic, or hypertonic, depending on how they affect fluid movement.

What does a hypotonic IV solution do?

A hypotonic IV solution draws water from the blood vessels into the cells, helping to rehydrate the body.

What does an isotonic IV solution do?

An isotonic IV solution has the same salt concentration as the body's fluids, so it stays in the bloodstream and increases blood volume.

What does a hypertonic IV solution do?

A hypertonic IV solution draws water from the cells into the blood vessels, which can be helpful in dehydration but can also cause fluid overload in the lungs.

Study Notes

IV Fluids

  • Crystalloids: small molecules, tonic solutions

    • Examples: blood products, albumin
    • Monitoring: for circulatory overload (fresh frozen plasma (FFP))

  • Colloids: large molecules

    • Examples: blood products, albumin

Tonic Crystalloids

  • Hypotonic:

    • 0.45% Sodium Chloride in Water (0.45% NaCl): half normal saline
    • Water movement: from bag into cells
    • Use: maintenance fluids, fluid replacement for those without needing sodium replacement.

  • Hypertonic:

    • 3% Sodium Chloride: water moves from cells into the bag
    • Dextrose 5% in 0.9% saline (D5NS): replaces sodium, chloride, & calories
    • Dextrose 5% in 0.45% saline (D5 1/2NS): replaces fluid

  • Isotonic:

    • 0.9% Sodium Chloride in Water (0.9% NaCl): normal saline
    • Effect: increases circulating volume, but stays in blood vessels.

Lactated Ringers

  • Use: low sodium replacement
  • Composition: normal saline with electrolytes and lactate
  • Use in surgery: replaces fluid and buffers pH
