Cerebrospinal fluids
These are not available for water and solute exchange with the remainder of the ECV
Extracellular Fluid:
Lot of Na+ (major cation)
Chloride (major anion)
These along with other small ions move freely between plasma and interstitium in the ECV
Plasma contains:
Proteins (albumin, globulins) which create colloid oncotic pressure.
Plasma proteins are prevented from moving freely from vascular to interstitial space by the vascular endothelial cells and the endothelial glycocalyx layer (EGL) coating the inside of the vascular space.
Crystalloids categorized
Crystalloids can be categorized based on their tonicity or osmotic pressure of the solution with respect to that of plasma
Large volumes of NS can result in
hypercholremic metabolic acidosis
Balanced or Physiologic crystalloid solutions contain a composition approximating that of extracellular fluid but are usually slightly hypotonic because of lower sodium concentrations
