Question 1

What is the equation to estimate pediatric weights?

Answer 1

50th percentile weight (kg)= (age x2) + 9
<1: age/(month)/2+4

Question 2

Kg: 0-10kg

Answer 2

4ml/kg/hr for each kg of body weight

Question 3

MIVF calculations for Pediatrics
kg: 10-20

Answer 3

40ml +2ml/kg/hr for each kg >10kg

Question 4

MIVF calculations for Pediatrics
kg: >20

Answer 4

60ml + 1ml/kg/hr for each kg>20kg

Question 5

How do you calculate max allowable blood loss?

Answer 5

[EBV x(starting Hgb-target hgb)]/target hgb

Question 6

How do you calculate the volume of PRBCs that need to be transfused?

Answer 6

[(desired HCt- present Hct)xEBV]/ Hct of PRBCs (~60%)
[(0.3-0.20x 800ml)]/0.60= 113ml
