Study Notes
Body Heat Loss and Transfer
- Approximately 10% of the body's heat is lost through conduction.
- Convection involves the warming of air surrounding the skin, facilitating heat transfer.
Body Temperature and Fever
- Hyperthermia refers to a temporary rise in body temperature.
- Pyrexia describes an elevation of body temperature due to a substance in the bloodstream.
- Localized infections, such as abscesses or cellulitis, can cause a localized fever.
Types of Fever
- A regular fever is characterized by consistent patterns of temperature rise and fall.
- Trypanosomiasis and Equine infectious anemia commonly present as remittent fever.
- Ephemeral fever is typically defined by short duration and sudden onset.
- Continuous fever presents prolonged fever periods with equal non-febrile intervals.
- The primary distinction between regular and irregular fevers lies in the temperature patterns and variations.
Thermoregulation
- The primary source of heat gain in the body is metabolic processes.
- The body's balance maintains homeostasis between heat production and heat loss.
- Catabolism is the process of breaking down complex substances into simpler ones.
- The hypothalamus serves as the central regulator in thermoregulation, integrating input signals.
- Circulating blood plays a crucial role in distributing heat throughout the body.
Body Heat Elimination
- Body heat is continuously eliminated through a variety of mechanisms, including convection, conduction, radiation, and evaporation.
Fever Characteristics
- An affected animal in a state of fever often exhibits general malaise and altered behavior.
- Prolonged fever can lead to intestinal dysfunction due to impaired circulation and metabolic shifts.
- Functional parts of an organ in the body are referred to as parenchyma.
- Chronic or long-continued fever results in tissue damage and potential organ dysfunction.
Fluid and Electrolyte Balance
- Healthy animals maintain a dynamic balance of fluids and electrolytes.
- Fever typically increases respiration rate due to heightened metabolism and oxygen demand.
- Water constitutes about 60% of body weight in healthy adult animals.
- Hydration status can be assessed through various clinical signs and tests.
Dehydration Indicators
- A minimum fluid loss of 5-6% body weight is required for clinical signs of dehydration to appear in a calf.
- Prolonged capillary refill time can indicate poor circulation and potential dehydration.
- A dehydrated calf may exhibit sunken eyes as a sign of fluid loss.
- Normal capillary refill time in healthy animals ranges from 1 to 2 seconds.
