    Study Notes

    Isotonic Fluids

    • Isotonic fluids have the same concentration as body fluids.
    • Common examples include 0.9% NaCl, D5W, Lactated Ringer's solution, and Ringer's solution.

    Hypotonic IV Fluids

    • Hypotonic solutions lower solute concentration compared to blood.
    • Key examples are 2.5% Dextrose in Water and 0.45% Normal Saline (NS).
    • Not suitable for head injury patients due to increased risk of cerebral edema.

    Hypertonic IV Fluids

    • These fluids have a higher solute concentration than the blood.
    • Includes solutions like D5NS, D5 ½ NS, D5LR, and TPN.

    0.9% NaCl (Normal Saline)

    • An isotonic solution used to expand extracellular fluid volume.
    • Helps prevent mild metabolic alkalosis and serves as an electrolyte replacement.
    • Clinical applications include shock management, resuscitation, fluid challenges, blood transfusions, treating metabolic alkalosis, hyponatremia, and Diabetic Ketoacidosis (DKA).

    0.9% NaCl Uses

    • Administered in shock, blood transfusions, and flushing lines.
    • Used to prevent an increase in blood bicarbonate and to manage low sodium levels.
    • Compatible with various medications.

    Contraindications for 0.9% NaCl

    • Not recommended for patients with severe hypertension, pulmonary edema, heart failure, edema, or hypernatremia.

    Lactated Ringer's Solution

    • A crystalloid isotonic solution for fluid and electrolyte replacement.
    • Often used in surgical settings for volume expansion and maintenance of electrolyte balance.
    • Prevents or corrects mild acidosis without providing calories.

    Lactated Ringer's Uses

    • Effective in treating dehydration, burns, GI fluid loss, acute blood loss, and surgical maintenance.

    Contraindications for Lactated Ringer's

    • Not suitable for patients with liver disease due to ammonia processing issues and those with renal issues due to potassium content.

    D5W (5% Dextrose in Water)

    • A volume expander primarily for fluid replacement without electrolytes.
    • Begins as isotonic but becomes hypotonic upon metabolism of glucose.

    D5W Uses

    • Administered for fluid loss, dehydration, and maintaining blood sugar levels in NPO patients.

    Contraindications for D5W

    • Avoid use in head injury cases and severe dehydration due to risk of water intoxication.

    General Hypotonic Information

    • Hypotonic solutions draw water into cells, causing them to swell.

    0.45% Normal Saline

    • Known as Half Normal Saline, it's a hypotonic electrolyte replenisher for dehydrated patients, providing no calories.

    0.45% Normal Saline Uses

    • Used to address gastric fluid loss, cellular dehydration, and hypertonic dehydration with slow rehydration.

    Contraindications for 0.45% Normal Saline

    • Not advised for patients at risk of increased intracranial pressure or for rapid rehydration.

    2.5% Dextrose in Water

    • A low dose hypotonic solution similar to D5W, providing 85 calories per liter and contraindicated for head injury patients.

    General Hypertonic Information

    • Hypertonic solutions have higher salt concentrations, drawing water out of cells.

    D5NS (5% Dextrose in Normal Saline)

    • Contains both D5 and 0.9% NaCl, suitable for patients with overhydration or edema, but not recommended for diabetics.

    D5LR (5% Dextrose in Lactated Ringer's)

    • A hypertonic dextrose solution effective for hypovolemic and hemorrhagic shock; avoid in cardiac or renal patients due to high fluid pressure.

    D5 ½ NS

    • Hypertonic dextrose solution used for heat exhaustion and diabetic disorders; should not be used for rapid fluid replacement.

    TPN (Total Parenteral Nutrition)

    • A hypertonic, nutritionally complete solution containing dextrose, proteins, lipids, and electrolytes; bypasses the digestive system, indicated for patients on total GI rest or recovering from bowel resection.
