Q

Holliday-Segar method is for…

How do you do it? ex: 21 kg kid.

A

IV maintenance rate
100 cc/kg per 24 hours for first 10 kg
50 cc/kg per 24 hours for second 10 kg
20 cc/kg per 24 hours over 20 kg

1500+20 = 1520
1520/24 = 63.3 cc per hour

A

IV maintenance rate

4 cc/hr x 10 kg = 40 cc/hr

Q

What’s the problem with treating a baby, young child with severe shock/dehydration? What do you do about it? Last resort?

A

getting an IV on this kid is going to be a crazy challenge. It’s a fairy tale, you won’t even be able to palpate it.

Check out their external jugular vein. If that’s used, make sure you point the needle DOWN towards heart, not up towards the brain.
Last resort location: intraosseus - tibial plateau line.

Q

A 14 gage needle won’t go into a kid. If it’s used on an adult, how quick will you get a Liter of fluid?

Q

Law of fluid dynamics – there are 2 factors that determine how fast you’ll get fluid into a patient:

What’s most rapid?
What are central lines?

A

length of IV catheter, and the diameter of the catheter.
Most rapid: So we want a shorter catheter and a wider diameter
Central lines are a huuuuge catheter with a narrow diameter. Therefore this is slower than a 14 gage needle.

Q

Identifying symptoms of Severe Dehydration implies ___% fluid deficit from ideal body weight.

So what if the kid’s ideal body weight is 20 kg?

A

10% fluid deficit from IBW

20kg x .1 = 2 kg loss.
2 kg = 2000 cc total deficit fluid loss

Q

Let’s talk through the whole process of correcting fluids in this 4 year old kid who weighed 20 kg a week ago, now weighs 18 kg and is severely dehydrated.

A

2000 total deficit
20 ml/kg resuscitative bolus: 20 x 20 = 400 cc (1600 cc deficit remaining)
800 cc over 8 hours = 100 cc/hr + 60 cc/hr for maintenance = 160 cc/hr
800 cc over following 16 hours = 50 cc/hr + 60 cc/hr for maintenance = 110 cc/hr
