Fluid viscosity

9

Catheter Complications

Thrombosis
Septic Phlebitis
Perivascular leakage
cracking
Abscessation
neurologic dysfunction
sloughing
Breakage - loss in heart and lung

10

What can occur from bilateral thrombosis?

Acute Respiratory Distress Syndrome - edema and closure of the nasal passages

11

What is the local effect of Hypertonic Saline?

draws fluid from 3rd space and intracellular environment

12

What is the central effect of Hypertonic Saline?

Stimulates a CNS response favoring CV stability

13

What are the averse reactions of equines to Hypertonic saline?

Hemolysis
Cardiovascular alterations

14

What are the contraindications for Hypertonic saline?

Uncontrolled Hemorrhage
Severe Hypernatremia
Severe Hypokalemia

Metabolic Alkalosis

17

How do you treat acute Hyper/Hypo-natremia?

Rapid Re-establishment of normal range of sodium

18

How do you treat chronic Hyper/Hypo-natremia within the compensatory range?

Slow establishment of normal range of sodium

19

How do you treat chronic Hyper/Hypo-natremia outside the compensatory range?

Rapidly drop their level and then slowly bring them back to normal level

20

What causes Synchronous Diaphragmatic Flutter (SDF)?

underlying electrolyte acid/base disturbance
