Electrolyte and Fluid Balance

Question 1

What are the classifications of IV fluids?

Answer 1

CrystalloidColloid/Synthetic colloidFree waterHybridsBlood productK additives

Question 2

What is a crystalloid fluid?

Answer 2

Small molecules that can cross cell membranese.g. Normal saline, Hartmann’s solution

Question 3

What is a colloid fluid/synthetic colloid fluid?

Answer 3

Large molecules (e.g. albumin, gelatin - synthetic) that remain in the intravascular space -> expand IV space longer than crystalloid

Question 4

What is a colloid fluid/synthetic colloid fluid?

Answer 4

Large molecules (e.g. albumin, gelatin - synthetic) that remain in the intravascular space -> expand IV space longer than crystalloid
