Why 20cc/kg?

[spoonfats]

I have been asked the question by an attending; why in peds do we always start with 20cc/kg of IV fluid for a bolus? I think he is looking for some specific reason, but I can't figure it other than that you're replacing 2% dehydration, which is a good small amount to start with. Anybody know why specifically we use 20? Thanks!

Actually, after just taking PALS early this month, it appears they are kind of getting away from this in certain situations. I think most people will start advocating smaller boluses (i.e. 5-10 cc/kg) at a time and see the response. Especially if you are concerned about some sort of cardiogenic shock.

But as to the number 20 cc/kg who knows. Hey, why do we treat most things for 5, 7, 10, or 14 days with antibiotics? How come nobody ever says 6 or 8? Probably because these numbers are entrenched. 5 - standard work week. 7 - one week. 10 - nice round nubmer. 14 - 2 weeks.

1. Round number
2. Somehow has to come back to the 70kg male.

I thought antibiotic days were based on possible Football scores and their multiples:

3 days = field goal
7 days = TD w/ PAT
10 days ... well you get the point.

I tell everyone to take them until the Red Sox win a World Series. That should be plenty long enough.
