Study Notes

Importance of Fluid Therapy

Can be life-saving in certain conditions
Loss of body water can cause problems ranging from mild headache to convulsions, coma, and death

Types of Fluids

Colloid Solutions

Contain large molecules that don't pass cell membranes
Expand intravascular volume and draw fluid from extravascular spaces via higher oncotic pressure

Crystalloid Solutions

Contain small molecules that flow easily across cell membranes
Increase fluid volume in both intravascular and interstitial spaces

Isotonic Solutions

0.9% sodium chloride (Normal Saline)
- Simply salt water containing sodium and chloride
- Used for severe diarrhea, vomiting, hemorrhage, fistulas, wounds, shock, mild hyponatremia, and metabolic acidosis
Ringer's lactate or Hartmann solution
- Most physiologically adaptable fluid, closely related to body's blood serum and plasma composition
- Used for burn and injury patients
Ringer's solution
- Contains sodium, potassium, calcium, and chloride in similar proportions to LR, but without lactate
Dextrose 5%
- Isotonic solution, but becomes hypotonic when dextrose is metabolized, causing fluid to shift into cells

Hypotonic Solutions

Lower concentration of solutes (electrolytes) compared to isotonic solutions
Osmolality less than 250 mOsm/L
Lower serum osmolality, causing fluid to shift from intravascular space to intracellular and interstitial spaces
Examples: 0.45% sodium chloride, 0.33% sodium chloride, 0.2% sodium chloride, and 2.5% dextrose in water
Used to treat patients with intracellular dehydration, hypernatremia, diabetic ketoacidosis, and hyperosmolar hyperglycemic state

Hypertonic Solutions

Higher tonicity or solute concentration
Osmolarity of 375 mOsm/L or higher
Draw water out of intracellular space, increasing extracellular fluid volume
Examples: 3% sodium chloride, 5% dextrose with normal saline (D5NS)
Used for severe hyponatremia, cerebral edema, and as volume expanders

Colloid Solutions

Expand intravascular volume by drawing fluid from interstitial spaces
Require administration of less total volume and have a longer duration of action
Examples: albumin (Human albumin 5% solution), hydroxyethalstarches

Precautions and Complications

Hypotonic solutions: decrease in vascular bed volume, worsen hypovolemia and hypotension, and cardiovascular collapse
Hypertonic fluids: intravascular fluid volume overload and pulmonary edema
Colloid solutions: interfere with platelet function, increase bleeding times, and anaphylactic reactions
Complications of fluid therapy: phlebitis, infiltration, extravasation, hemorrhage, local infection, pulmonary edema, and air embolism
