A 3 year old male has full thickness burns covering his arms, posterior trunk and right leg. What percentage of burns did he receive?

To determine the percentage of burn coverage for a 3-year-old male with specified areas affected, it's important to use the "Lund and Browder Chart" or the "Rule of Nines" adapted for children, as their body proportions differ from adults.

Using the Rule of Nines for calculating burns in pediatric patients, the body is divided into segments, with each corresponding to a certain percentage of total body surface area (TBSA). In this case:

• The arms (both arms together) contribute approximately 18% (9% per arm).
• The posterior trunk is typically considered about 18% of total body surface area.
• The right leg (one leg) contributes around 14% of TBSA.

Adding these percentages together:

• 18% (arms) + 18% (posterior trunk) + 14% (right leg) = 50% TBSA burned.

Thus, the correct percentage of burn coverage for the described patient is 50%. This calculation illustrates the importance of using established guidelines and anatomical understanding when assessing burns in pediatric patients, leading to accurate and effective treatment planning.
