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

History:
- Includes information on fluid intake, output, and any relevant medical conditions.
Physical Examination:
- Allows assessment of clinical signs like:
  - Skin turgor
  - Mucous membrane dryness
  - Pulse and heart rate
  - Blood pressure
  - Respiratory rate
  - Mental status
Laboratory Tests:
- Blood tests, including:
  - Electrolytes (sodium, potassium, chloride)
  - Blood urea nitrogen (BUN)
