Fluid Therapy Objectives
- Define dehydration as the state where fluid loss exceeds intake, reducing overall body water content.
- Understand clinical signs of dehydration, including but not limited to:
- Decreased urine output
- Increased thirst
- Dry mucous membranes
- Sunken eyes
- Tachycardia
- Hypotension
- Lethargy
- Decreased skin turgor
Normal Water Output
- Sensible losses:
- Primarily through urine
- Insensible losses:
- Includes fecal matter
- Also includes respiratory losses through exhalation
Fluid Losses
- Fluid losses occur when the body consumes less fluid than it excretes.
- This can occur during periods of food and water restriction, exaggerated sensible and insensible losses, or due to underlying disease processes.
Dehydration
- Net reduction in the free water content of the body.
- Classified based on the type of fluid lost and the effects on remaining body fluids.
Indications for Fluid Therapy
- Maintain fluid volume in instances of:
- Dehydration
- Shock
- Systemic diseases
- Diuresis
- Hypoproteinemia
- Anesthesia
Assessment of Fluid and Electrolyte Imbalance
