Burn injuries are some of the most critical and time-sensitive emergencies in medical care. The Rule of Nines provides a fast, reliable method for assessing burn severity by calculating the total body surface area (TBSA) affected. This simple, yet powerful tool is essential for clinicians, first responders, and medical students, helping to prioritize care, guide fluid resuscitation, and predict potential complications. By dividing the body into sections that each represent roughly 9% of the total surface area, the Rule of Nines chart offers a clear framework for swift decision-making in high-pressure situations. Understanding this rule is not just vital for effective burn treatment—it could mean the difference between life and death.
