Dehydration

Question 1

Maintenance calculation

Answer 1

100 + 50 + 20 rule / 24hr

4 + 2 + 1 rule

Question 2

Replacement calculation

Answer 2

Maintenance + deficit - bolus

e.g. 25kg child 5% dehydrated

Maintenance = 1600ml (1000 + 500 + 100)
Deficit = 25 kg x 5% = 1250
Replacement = 2850/24 = 118ml/hr

Question 3

Fluid types used in maintenance, replacement, and resuscitation

Answer 3

Maintenance = 0.9 NaCl, 5% glucose, +/- KCl (20mMol)

Replacement = 0.9 NaCl, 5% glucose, +/- KCL (20mMol)

Resusc = 0.9 NaCl

Question 4

Resusc fluid amount

Answer 4

10ml/kg bolus of normal saline

Question 5

Fluid given in mild dehydration (i.e. trial of fluid)

Answer 5

0.5ml/kg every 5mins. Try oral/enteral first

Question 6

HR
RR
skin turgor
frontonelle
