For a child, a burn greater than which percentage is considered life-threatening?

A burn greater than 20% of the total body surface area in a child is considered life-threatening due to several factors, including the child's smaller body size and greater relative risk of complications compared to adults. Children have a higher metabolic rate and a larger surface area-to-volume ratio, which makes them more susceptible to fluid loss, shock, and infection following significant burns. When more than 20% of the body surface area is burned, it can lead to serious physiological responses, including hypovolemic shock, severe pain, and prolonged healing times. Therefore, a burn of this magnitude requires immediate medical intervention and often specialized burn care. Understanding the implications of burn severity in children is crucial for appropriate assessment and treatment.
