Rule Of Nine

Rule of Nine - well all we know rule of nine is applied in case of burns

Here i would like to tell how to remeber the difference in rule of 9 in children and Adults

Adults we know

1 Head and upper extremity eacch assigned  9
2 Each lower extremity assigned two 9 units
3 Trunk assigned 4 units of 9 each

In Children

The concept being Babies have Bigger heads and smaller legs thus - two 9 for head and both legs share 3 9's instead of 4
