Unit 1 - Fluid Therapy Flashcards
What are colloids?
Synthetic molecules, large molecular weight that keeps the fluid in the vasculature and provides oncotic support
Provide an example of a colloid.
Hetastarch or Oxyglobin
When is Hetastarch typically used?
For oncotic support in LA due to hypoalbuminemia
What are crystalloids?
Small salt-based solutes that rapidly distribute into the extracellular space
Provide an example of a crystalloid.
LRS, Normosol, 0.9% NaCl, Plasma-lyte
What is the fluid of choice for therapy of RDA?
isotonic fluid - 0.9% NaCl for example
What are replacement fluids used for?
To replenish fluid deficits primarily those in the extracellular fluid department
What types of fluids are used for replacement fluids?
Normosol-R, Plasma-lyte, and LRS
What are maintenance fluids?
Fluids that are used to maintain metabolism, insensible losses, growth, and ongoing losses
What is the maintenance fluid rate for cows?
2-3 ml/kg/hr
Provide an example of a fluid that is used for maintenance fluids.
Plasma lyte
What should the composition of Na, Cl, and K be for replacement fluids?
High Na and Cl, and low K
What should the composition of Na, Cl, and K be for maintenance fluids?
Less Na and Cl, and add K
If you are given base deficit, how do you calculate estimated bicarbonate deficit?
BW(kg) x base deficit x 0.6 (calves)
BW (kg) x base deficit x 0.3 (adults)
If you are given base excess, how do you calculate estimated bicarbonate deficit?
The same as base deficit
BW x base excess x 0.3 (adults)
BW x base excess x 0.6 (calves)
