The crystalloid vs colloid wars are being duked out, but in the meantime, I finally heard a helpful lecture re: colloid equivalents:
NS or LR 500 ml dose = 100-200 ml intravascular
5% albumin (used for resuscitation) 500 ml = 500 ml intravascular
25% albumin (SBP, etc) 100 ml = 300 ml intravascular (because of oncotic pressure pulling in fluid from interstitium)
Hespan 500 ml = 600 ml intravascular (same reason as above)
