What is Fluid Therapy?
Fluid Therapy is the administration of fluids to a patient as a treatment or preventative measure. It can be administered via an intravenous, intraperitoneal and subcutaneous routes. 60% of total bodyweight is accounted for by the total body water. This can further be divided into intracellular or extracellular as shown below.
Fluid therapy is indicated when there is a loss of fluid to any part of these compartments. The severity of the fluid loss, and the compartment which is has been lost from with influence the choice of fluid.
Indications
- Hypotension
- Hypovolemia
- Electrolyte, metabolic and acid base disorders
- Decreased oxygen delivery
- Geriatric patients at risk of organ failure
Definitions
- Osmosis is the net movement of water across a semi permeable membrane. The movement is caused by a concentration gradient due to different solute concentrations.
- Osmotic Pressure is the pressure caused by the solutes within the solution. The solute concentration prevents water movement across the membrane.
- Tonicity is the term used to compare the osmotic pressure of different solutions
- A hypotonic solution is one that has an osmotic pressure lower than plasma.
- A isotonic solution is one that has an osmotic pressure the same than plasma.
- A hypertonic solution is one that has an osmotic pressure higher than plasma.
Types of Fluids
- Crystalloids
- Colloids
- Blood Products
