Figure- Rule of nines

Contents


___________________

What is the rule of nines?


Rule of nine is the quick method to estimate the percentage of burn in the body. It was advocated by Wallace(1951). In this rule, the human body is divided into sections by multiples of 9%.

Body parts and their percentage



Figure- Rule of nine flow chart


  • Head and neck of the body: 9%
    • Anterior part: 4.5%
    • Posterior part: 4.5%
  • Entire trunk: 36%
    • Chest: 18%
      • Anterior part: 9%
      • Posterior part: 9%
    • Abdomen: 18%
      • Anterior part: 9%
      • Posterior part: 9%
  • Both upper limbs: 18%
    • Right limb: 9%
      • Anterior part: 4.5 %
      • Posterior part: 4.5 %
    • Left limb: 9%
      • Anterior part: 4.5 %
      • Posterior part: 4.5 %
  • Both lower limbs: 36%
    • Right limb: 18%
      • Anterior part: 9 %
      • Posterior part: 9 %
    • Left limb: 18%
      • Anterior part: 9 %
      • Posterior part: 9 %
  • Groin: 1%
Note: The surface area of the palm of the patients is roughly about 1% of the total body surface area and the palm without the digits roughly makes 0.5% of the total body surface area.
________________________________

What are the limitations of rule of nine?

  • Obese people: rule of nine may not be accurate for obese people
  • Children: children have different head to body ratio than adults. We should modify the rule of nines to apply on children.
