lecture 3 - polzin1 - fluids Flashcards
1
Q
- what % of body is water?
- how does ^age affect?
- how does ^fat affect?
A
- 60%
(534 - 660 mL/kg in normal dogs)
- lowers it
- lowers it
2
Q
- what percentage of body water is ICF?
ecf?
- how much of ecf is plasma? interstitial?
- how much is blood by bw in…
dogs?
cats?
A
- 2/3
1/3…
- 25%, 75%
- 8-9%
6-7%
3
Q
- big dog needs 40 mL/kg/day - small dog needs 60 - why is this?
A
- surface area
4
Q
- never give fluids faster than what?
A
- 1 blood volume per hour
5
Q
- what is sensible fluid loss
- what is insensible?
- what are additional pathological ∆s called?
A
- urine (can be measured)
- fecal, respiratory, cutaneous
- ongoing losses
6
Q
1-5. What are the five indications for fluid therapy?
A
- dehydration
- 2 hypovolemia
- maintain effective circulating volume
- colloidal oncotic support
- induce/promote diuresis
7
Q
1-3. What are the three parts of the fluid therapy plan and what does each part address?
A
- replacement - pathologic losses
- maintenanace - normal losses
- ongoing losses (contemporary losses)
(fix the deficit –> prevent additional losses)
8
Q
1-5 what five questions when giving flui therapy?
A
- how much
- what type
- how fast
- where
- how to monitor
9
Q
(deciding how much fluid is needed)
- estimate based on what?
- how about for shock patients?
A
- physical findings
history of losses
lab assessments
- to effect - not based on volume!!!
10
Q
- what is the main extracellular cation?
intracellular?
- so if you give fluids containing Na where will they go?
- if you give pure water where will it go
- what do you give if you only want vasculature fluid?
A
- Na
K
- ECF
- ICF and ECF
(not many things will deplete both)
- colloid or plasma
11
Q
(dehydration)
What would you see at each of these levels of dehydration?
<5%
5-6%
6-8%
10-12%
12-15%
A
