Anaesthesia | Paediatrics | Body Composition and Growth



Body Composition and Growth
Session Overview
Description
The session starts with an introduction to the concept of growth and development, and why this is important for paediatric anaesthesia pharmacology. This includes an important outline of what is ‘normal’. A key point of this session is for the trainee to learn how to calculate approximate weight from the age of the child. The session will also discuss changes in body composition such as muscle and fat, as well as developmental changes in fluid compartments and blood volume. Lastly, the session will indicate how organs develop in terms of relative size, blood flow and maturity. The implications of these factors are briefly discussed.
Learning Objectives
By the end of this session you will be able to:
- Discuss what is meant by ‘normal’
- Calculate the approximate weight of a child based on age
- Describe why growth and development is relevant to paediatric pharmacology
- Describe how the relative composition of the body changes with age in terms of water, fat, fluid compartments and blood volume
