B31 Flashcards
blood volume ca
80-90ml/kg
blood volume fe
60-65ml/kg
EC
1/3
Na and Cl
IC
2/3
K, phosphor, proteins
btw EC and IC
cell membrane
water and urea move freely
ions, glucose dont move
btw IV and IS
capillary wall
water, ions, glucose, urea - freely
proteins dont move
fluid uptake
eating, drinking
fluid loss
urine
faeces
panting
sweating
hypovolemia
absolute
due to burns or gastric torsion
IV fluid deficit
quick reaction is needed
dehydration
IS and IC deficit
there is time for reaction
% of dehydration
<5% - cant be detected 5-6% - sticky mm 6-8% - skin turgor 8-10% enophthalmos 10-12% - hypovolemia >12% - shcok and death
isotonic
salsol A (0.9% NaCl) ringers lactate
HES = Hydroxyethyl STARCH
hypotonic
salsol b (0.45%) 5% Glucose
hypertonic
10% NaCl
contraindications of fluid therapy
congestive heart failure
too fast, too much
isotonic crystalloid to give during dehydration
BW Kg x 10 x dehydration %
colloid
large moleules
natural - albumin, globuulin, fibrinogen
synthetic - starch, gelatine
lipofundin - artificial feeding
